Provedor de dados: 14
Autores: VIEIRA, R. F.; RAMOS, N. P.; PAZIANOTTO, R. A. A.
Resumo - Os efeitos da manutenção de quantidades diferentes de palha foram avaliados após a colheita da cana-de-açúcar, utilizando indicadores microbiológicos e enzimáticos de solo. O experimento foi conduzido utilizando três quantidades de palha: T0, toda a palha foi retirada do solo; T50 e T100, 50% e 100% da palha foram mantidas sobre o solo, respectivamente. O N da biomassa microbiana e a atividade da beta-glucosidase (AG) aumentaram com as quantidades de palha, ao contrário da atividade da urease. A respiração basal apresentou tendência crescente com o aumento das quantidades de palha. O nitrogênio potencialmente mineralizável (NPM) não apresentou diferença significativa entre os T50 e T100, mas foi maior do que o obtido no T0. Os resultados relativos...

Vários países têm tentado estabelecer valores de referência de solo ("background" ou "baseline") para elementos químicos tóxicos ou potencialmente tóxicos com vistas ao estabelecimento de uma legislação que regule o uso do solo como via alternativa para aplicação de resíduos domésticos/industriais. Com isso, mitigaria-se a acumulação de poluentes inorgânicos e seu possível impacto sobre a biota e as águas subterrâneas. No Brasil, a legislação referente ao assunto foi promulgada em 2009 (Resolução CONAMA nº 420 (Conselho Nacional do Meio Ambiente, 2009)). Nesse sentido, o objetivo principal do trabalho foi determinar os valores de referência de qualidade (VRQ) de uma série de elementos químicos (Fe, Mn, Sb, As, Ba, Cd, Pb, Co, Cu, Cr, Mo, Ni, Ag, Se, V e...

The characterization and composition of bacterial communities in soils blended with spent foundry sand
Provedor de dados: 18
Autores: Dungan, R.S.; Kim, J.; Weon, H.; Leytem, A.B.
The purpose of this research was to characterize the structure and composition of bacterial communities in  sandy loam and silty clay soils amended with 30% spent sand from iron, aluminum, and steel foundries. All spent foundry  sand (SFS) blends were grown with or without perennial ryegrass and samples were collected at 4 weeks and 6 months.  Regions of the 16S rRNA gene were amplified using PCR and subsequently analyzed by DGGE and sequenced for bacterial  identification and phylogenetic classification. Cluster analyses of PCR-DGGE banding patterns revealed that SFS blends  from week 4 and month 6 produced unique clusters, with most ryegrass treatments clustering away from those without  ryegrass. The diversity of the bacterial community revealed that it...

Autores: Blecker, S.W.; STILLINGS, L.L.; MCAMACHER, M.C.; Ippolito, J.A.; DECRAPPEO, N.M.
Soil quality indices are often management driven and attempt to describe key relationships between above- and below-ground parameters.  In terrestrial systems, indices that were initially developed and modified for agroecosystems have been applied to non-agricultural systems in increasing number. We developed a soil quality index in arid and semi-arid ecosystems of the Western US impacted by different types of geologic mineralization using the relationship between vegetation community parameters and soil abiotic and biotic properties. We analyzed these relations in soils associated with three different mineralization types: podiform chromite, Copper/Molybdenum porphyry, and acid-sulfate gold vein systems at four different sites in California and Nevada....

Provedor de dados: 18
Autores: Ippolito, J.A.; Spokas, K.A.; Novak, J.M.; Lentz, R.D.; Cantrell, K.B.
Biochar is the carbonaceous solid byproduct of the thermochemical conversion of a carbon-bearing organic material, commonly high in cellulose, hemicelluloses, or lignin content, for the purposes of carbon sequestration and storage.  More specifically, the thermal conversion process known as pyrolysis occurs when carbon-containing substances are introduced to elevated temperatures in the absence of oxygen at varying residence times, yielding biochar.  Several pyrolysis techniques employed to produce biochar differ in the temperature of reaction and residence time in the reactor.  Different reactor residence times are described as slow (hours to days), fast (seconds to minutes), and flash (seconds).  Fast or flash pyrolysis typically occurs around 500oC with...

Droughts associated with low or erratic rainfall distribution can cause detrimental crop moisture stress. This problem is exacerbated in the USA’s arid western and southeastern Coastal Plain due to poor rainfall distribution, poor soil water storage, or poorly-aggregated, subsurface hard layers that limit root penetration. We hypothesized that soil physical deficiencies may be improved by biochar applications. Research indicates a single biochar will not serve as a universal supplement to all soils; consequently, biochars may need to be designed with physico-chemical properties that can ameliorate specific soil physical deficiencies. We conducted a laboratory study that examined the effect of biochar on soil moisture retention and aggregate formation....

Aluminum-based water treatment residuals (Al-WTR) have a strong affinity to sorb phosphorus.  In a proof-of-concept greenhouse column study, Al-WTR was surface-applied at 0, 62, 124, and 248 Mg/ha to 15 cm of soil on top of 46 cm of sand; Al-WTR rates were estimated to capture 0, 10, 20, and 40 years of phosphorus from an urban watershed entering an engineered wetland in Boise, Idaho, USA.  Creeping red fescue (Festuca rubra) was established in all columns; one set of columns received no Al-WTR or plants.  After plant establishment, once per week over a 12-week period, ~1.0 pore volumes of ~0.20 mg phosphorus/L was added to each column.  Infiltration rates were measured, leachate was collected and analyzed for soluble phosphorus, and fescue yield,...

Case Study: On-Farm Evaluation of Liquid Dairy Manure Application Methods to Reduce Ammonia Losses
Provedor de dados: 18
Autores: Leytem, A.B.; Bjorneberg, D.L.; Sheffield, R.E.; de Haro Marti, M.E.
The volatilization of NH3 from landapplied manure is not only a loss of valuable N, but also an air quality concern because NH3 plays a role in the formation of airborne particulate matter, which can be a health hazard. The relative differences in potential NH3 losses from land application of liquid dairy manure were determined via 3 methods: surface application, Aerway incorporation (shallow incorporation with a rolling tine aerator), and subsurface injection. Liquid manure was applied at a rate of 190 m3/ha on 4 farms with average N and P application rates ranging from 28 to 130 kg N/ha and 6 to 36 kg P/ha, respectively. Average NH3 concentrations were measured with passive samplers for 3 d after manure application and ranged from 0.03 to 0.21 mg...

Quality soil management or soil quality management: Performance versus semantics
Provedor de dados: 18
Autores: Sojka, R.E.; Upchurch, D.R.; Borlaug, N.E.
In the past 200 years, soil science has used reductionist research to develop agricultural technologies that have unlocked the hidden potential of earth's natural systems to feed, clothe, and provide raw materials to the human population of over six billion. The soil quality paradigm seeks to change that scientific approach, the nomenclature of soil science, and institutional priorities for soil management and research. The definition of soil quality is elusive and value-laden. Concerns exist for the paradigm's policy overtones, regional and taxonomic biases, failure to reconcile conceptual contradictions, as well as its ambiguous definitions that are confounded by countless circumstance-specific, function-dependent scenarios. The paradigm does not...

Excessive copper concentrations in water systems can negatively impact biological systems.  Because copper can form strong associations with organic functional groups, we examined the ability of biochar (a carbon-enriched organic bioenergy by-product) to sorb copper from solution.  In a batch experiment, potassium hydroxide-steam activated pecan shell biochar was shaken for 24 hours in pH 6, 7, 8, or 9 buffered solutions containing various copper concentrations to identify effect of pH on biochar copper sorption.  Afterwards, all biochar solids from the 24 hours shaking period were air-dried and then analyzed using X-ray absorption fine structure spectroscopy to determine solid-phase copper speciation.  In a separate batch experiment, biochar was shaken...

The sustainability of modern manure management is far from certain, with many demonstrating significant limitations from the stand point of efficient use of manure resources and protection of environmental quality and human health. As demonstrated through this review, for manure management to be sustainable, a broad array of issues must be considered and addressed, all in the context of highly competitive modern livestock production systems that largely seek to minimize costs to the consumer. In the past decade there have been major innovations in the areas of land application, manure treatment and processing and in the science of understanding the impact of manure management. As a result, major opportunities exist to improve the components of manure...

Magnesium phosphates such as struvite (MgNH4PO4x6H2O) can be recovered from municipal, industrial and agricultural wastewaters.  However, minimal research has been conducted on the beneficial reuse of these recovered products; conducted research has focused on low pH soils.  This study determined whether recovered struvite and dittmarite (MgNH4PO4xH2O) were effective P fertilizers in alkaline soils.  In addition to commercially available triple superphosphate (TSP) and certified organic rock phosphate (RP), recovered struvite, dittmarite, and a heterogeneous recovered phosphate were evaluated in a laboratory dissolution study and as fertilizers for spring wheat (Triticum aestivum L.) in a greenhouse study.  Struvite and dittmarite were much more soluble...

Use of standardized procedures to evaluate metal leaching from waste foundry sands
Provedor de dados: 18
Autores: Miguel, Roberto E.; Ippolito, J.A.; Noriega, Roxana B; Dungan, R.S.
As part of the casting process, foundries create sand molds and cores to produce ferrous and non-ferrous metal castings.  After the process, a portion of the sand is discarded and becomes waste foundry sand (WFS). The aim of this study was to quantify metals (i.e. Ag, Ba, Cd, Cr, Cu, Ni, Pb, and Zn) in leaching extracts from a variety of waste molding and core sands from ferrous and non-ferrous foundries using the Extraction Procedure, Toxicity Characteristic Leaching Procedure, and ASTM water extraction procedure. The WFS metal extract concentrations were compared to those found in virgin silica sands and Argentinean and U.S. hazardous waste laws to determine if the WFSs met toxicity limits. The majority of the WFS extracts analyzed, regardless of metal...

The effects of biochar and manure in silage corn
Provedor de dados: 18
Autores: Lentz, R.D.; Ippolito, J.A.; Spokas, K.A.
Amending soil with biochar may be a means of sequestering atmospheric CO2 and improving soil quality, but few multiyear field studies have examined the impacts of a one-time biochar application in an irrigated, calcareous soil. We fall-applied four treatments: dairy manure (18.7 tons/ac dry wt.); hardwood-derived biochar (10 tons/ac dry wt.); combined biochar and manure; and no amendments (control). We measured net N-mineralization using buried soil bags and soil greenhouse gas emissions (CO2, CH4, and N2O) from late spring to fall, corn silage yields, and crop N uptake each year. The influence of biochar and manure on silage yield changed with time after application in fall 2008. Biochar increased corn yields slightly (5%) in 2009, decreased yields by 14%...

Autores: Ippolito, J.A.; Lentz, R.D.; Novak M, J; Spokas, K.A.; Collins, H.P.; Streubel, J.
Soil fertility benefits of charcoal application have been reported as early as 1847 indicating that plant nutrients are sorbed within charcoal pores.  The use of biomass-derived black carbon or biochar, the solid byproduct from the pyrolysis processing of any organic feedstock, has garnered recent attention as a potential vehicle for carbon sequestration and a beneficial soil conditioner.  However, most of the past biochar research has focused on improving the physico-chemical properties of tropical (i.e. terra preta) and highly weathered soils, while little research has focused on improving arid or semi-arid soils of the USA.  Here, we present an overview of the potential benefits and drawbacks of biochar usage in western US agro-ecosystems based on...

Small Grain Residue Management Effects on Soil Organic Carbon:  A Literature Review
Provedor de dados: 18
Autores: Tarkalson, D.D.; Brown, B.; Kok, H.; Bjorneberg, D.L.
Impact of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) straw removal from fields on soil organic C (SOC) is a concern.  Increased animal populations and potential development of cellulosic ethanol production could increase the removal of straw from fields.  This paper focuses on the effects of wheat and barley straw removal on SOC in irrigated production systems, and related the results to estimates of the minimum straw C inputs required to maintain SOC (MSC) from rain-fed systems. Six studies compared SOC changes with time in irrigated systems in which wheat straw was removed or retained.  These studies indicated that SOC did not decline when residues were removed. Apparently belowground biomass is supplying C to irrigated soils at a rate...

Consequently, can regression equations reasonably estimate plant availability of Zn, P, Fe, and Cu, where multiple applications of Littleton and Englewood, Colorado Wastewater Treatment Plant biosolids are applied to a dryland wheat (Triticum aestivum L.)-fallow agroecosystem? Before each growing season, we added Littleton and Englewood biosolids at rates of 0 to 11.2 dry Mg ha?1 to plots arranged in randomized complete blocks with four replications per treatment. Soil samples collected after each wheat harvest were analyzed using an NH4HCO3-diethylenetriaminepentaacetic...

Biochar is being evaluated by scientists from the United States Department of Agriculture (USDA) Agricultural Research Service (ARS) for its potential to sequester soil C, to improve soil health, and to increase crop yields.  ARS scientists from multiple locations such as Florence, SC, Kimberly, ID, Bowling Green, KY, Corvallis, OR, and St. Paul, MN, are conducting investigations with agronomic experiments at the laboratory, greenhouse, and field plot scales. To further expand biochars utility, ARS scientists have collaborated with United States Environmental Protection Agency (US EPA) investigators to reclaim mine-impacted soils. In the agronomic investigations, both positive and negative aspects of biochar application were revealed.  In some experiments,...

In-field rates of decomposition and microbial communities colonizing residues vary by depth of residue placement and plant part, but not by crop genotype for residues from two Cry1AB Bt corn hybrids and their non-transgenic isolines.
Provedor de dados: 18
Autores: Londono-R, L; Tarkalson, D.D.; Thies, Janice E.
The adoption of Bt corn has been largely overshadowed by concerns about their unintended effects on human health and the environment. Residues of transgenic Bt crops decomposed more slowly than their non-transgenic isolines in one laboratory study, although no mechanism to explain these observations was proposed. If Bt crop residues were to decompose more slowly in field soils, changes in carbon cycling and nutrient availability could result. We compared the in-field decomposition rates and diversity of decomposers colonizing residues of two Cry1Ab Bt corn hybrids, active against the European corn borer, with their non-transgenic isolines in litterbags placed in a Nebraska field. After five months, we found no significant differences in either the rates of...

Fifteen Years of Wheat Yield, N Uptake, and Soil Nitrate-N Dynamics in a Biosolids-Amended Agroecosystem. Agriculture, Ecosystems and Environment
Provedor de dados: 18
Autores: Barbarick, K.A.; Ippolito, J.A.; McDaniel, J.P.
Understanding N dynamics in biosolids-amended agroecosystems can help avoid over-application and the potential for environmental degradation. We investigated 15-years of biosolids application to dryland-wheat, questioning what is the relationship between cumulative grain yield and N uptake (N removal) and biosolids or N fertilizer rates and how many times biosolids or N fertilizer are applied? How are wheat-grain production and N uptake intertwined with residual soil nitrate-N? We found that biosolids or N fertilizer rates plus the number of applications of each material produced planar-regression (3-dimensional) models with 15-years of grain yield and N uptake data (all R2 &gt; 0.93). To evaluate how yield or N uptake impacted residual soil nitrate-N, we...

Autores: Hoffmann, Heide; Hübner, W.
In einem langzeit-Feldversuch in Blumerg (bei Berlin) wurden seit 1993 landwirtschaftliche Nutzungssysteme miteinander verglichen. Untersucht und verglichen wurde die Entwicklung der Erträge, der Nährstoffzustand und biologische Parameter der Sandböden unter konventioneller und biologischer Bewirtschaftung. 7 Jahre nach Versuchsbeginn waren die Erträge der konventionellen Variante um 27% höher als die in der biologischen Variante. Es wurden nur geringe Unterschiede zwischen den Nährstoffgehalten der Anbausysteme. Die potentielle Bodenfruchtbarkeit, die in einem Gefäßversuch untersucht wurde, schien im biologischen Wirtschaftssystem höher zu sein. Die Auswertung der biologischen Parameter steht noch aus.

Provedor de dados: 21
Autores: Athmann, Miriam; Fetscher, Johannes; Zemke, Daniel; Kautz, Timo; Köpke, Ulrich.
Biopores have been shown to be enriched with plant available nutrients as compared to the surrounding bulk soil and therefore are considered hot spots for the nutrient acquisition especially in the otherwise nutrient-poor subsoil. As a result of colonization of biopores by earthworms, pore walls are enriched with nutrients. In this study, a first attempt was made to assess the influence of earthworm abundance on both structural pore wall characteristics as assessed with in situ endoscopy and on pore wall C and N contents. Higher earthworm density resulted in higher N contents and significantly higher C contents in biopore walls as compared to the surrounding bulk soil, regardless whether they showed visible earthworm coatings. In the treatment with lower...

Maiserträge und Humusbilanzen in ökologischen Energiepflanzen-Fruchtfolgen mit Gärrestdüngung
Provedor de dados: 21
Autores: Levin, Karin; Simon, A.; Reents, Hans Jürgen; Hülsbergen, Kurt-Jürgen.
The long-term effects of biogas production in organic farming on soil fertility due to changes in crop rotations and the removal of carbon from these systems are, at  present, unclear. Data from a long-term field trial in Bavaria, Germany were used to evaluate the effects of different crop rotations and fertilization with biogas digestate on maize yields and humus balances. Digestate fertilization led to higher maize yields compared with an unfertilized control. Maize yields were lower when the maize was sown directly into a white clover cover crop. Humus balances show the importance of considering both the return of organic matter via fertilization and crop rotation design  to ensure that soil fertility is not depleted

The work aims to investigate the effects of different soil management strategies on carbon sequestration and total nitrogen in areas of vineyards suffering from loss of soil functionality. Treatments, selected for inter-row management, to re-install soil functionality were based on compost or other organic amendments (COMP), green manure (GM), and dry mulching (DM) strategies using winter legumes and cereals. Cover crops were seeded in fall and mown in late spring, leaved in the ground for mulching in DM or incorporated into the uppermost soil layers in GM. Such approaches were investigated in six vineyards in Italy, six in France, and two vineyards in Slovenia and Turkey.     The results showed that COMP significantly increased total organic carbon (TOC)...

Akkumulation von Schadstoffen in europäischen Böden durch alternative Phosphordünger
Provedor de dados: 21
Autores: Weissengruber, Lina; Friedel, Jürgen K.; Möller, Kurt.
Der Vorsorgewert wurde nur von Cr überschritten. Es zeigt sich, dass das Verhältnis von Schadstoff zu Phosphor eine wichtige Rolle spielt. Von Düngern mit einem geringen P-Gehalt, wie den Komposten, muss eine größere Menge ausgebracht werden, was in dieser Berechnung zu einer höheren Schadstoffanreicherung führte. Grüngutkompost hatte das höchste Akkumulationspotenzial für alle Schwermetalle, nur bei Cadmium wurde er von Triplesuperphosphat übertroffen. Vermutlich ist die atmosphärische Schermetallbelastung von Grünschnitt in Städten und entlang von Straßen besonders hoch und konzentriert sich im Kompost. Die Schadstoffgehalte der Dünger können, je nach Ausgangssubstraten, unterschiedlich sein. Als Phosphordünger eingesetzt, hatten Struvite, Fleisch- und...

In order to assess the risk of the use of recycled phosphorus (P) fertilisers for organic farming, the potential accumulation of heavy metals in soil after a 200-year fertilizer application equivalent to 11 kg P ha-1 yr-1 was calculated in a mass balance approach. Both fertilizers currently allowed in organic farming and recycled P fertilizers were regarded. For heavy metals, four scenarios with two soil pH levels (pH 5 and pH 7) and two precipitation excess levels (F 0.1 and F 0.3 m yr-1) were calculated. Recycled P fertilizers like struvite, meat- and bone meal, ashes, sewage sludge and digestate, as well as phosphate rock and triple superphosphate had a higher P content and a lower heavy metal-to-P ratio than composts. Consequently, compost application...

Zusammenfassung  Die nachhaltige Erhaltung und Steigerung der Bodenfruchtbarkeit ist für ökologisch wirtschaftende Betriebe von höchster Bedeutung. Im Öko-Landbau hängt das Niveau der Bodenfruchtbarkeit – abgesehen von den kaum zu beeinflussenden standörtlichen Gegebenheiten – sehr von der Leistungsfähigkeit der Leguminosen (N2-Fixierungsleistung, Durchwurzelungsvermögen) ab. Sie haben somit die Schlüsselstellung für die Verbesserung des Bodenfruchtbarkeitsmanagements im Öko-Landbau, speziell im Marktfruchtbau. Leguminosen werden allerdings stark durch bodenbürtige Pathogene beeinträchtigt. Auch die Art der Bodenbearbeitung, die im Öko-Anbau vergleichsweise intensiv ist, und das Befahren der Böden haben einen Einfluss auf die Bodenfruchtbarkeit, da bekannt...

Abstract - In our research we have evaluated a series of soil indicators to determine the correlation between individual soil properties in organic farming. Regression analysis has proven that the biological activity of the soil on organically farmed areas (grasslands) as expressed by respiration is mainly influenced by the bulk density, moisture, porosity, humus content, the proportion of cation exchange capacity and total nitrogen content. The multiple regressions have proven the important dependency of basal respiration to the moisture, bulk density and total nitrogen. The supply of organic matter to the soil environment, thus greatly influences the studied soil biological activity. Similar dependences were visible in the results of both conventional...

Autores: Fuchs, J. G.; Baier, U.; Berner, A.; Mayer, J.; Tamm, L.; Schleiss, K.
Composts can influence soil fertility and plant health. These influences can be positive or negative, depending of the quality of the composts. Some practitioners already make use of the positive effects on plant health. For example, they use composts to protect their plants against soil borne diseases in substrate, or to detoxify and reactivate soil after steaming. In order to estimate the potential of Swiss composts to influence  soil fertility and plant health positively, we analyzed one hundred composts representative of the different composting systems and qualities available on the market.    The organic substance and the nutrient content of the composts varied greatly between the composts; the materials of origin were the major factor influencing...

No-tillage (NT) and reduced tillage (RT) systems are well-known management tools for reducing soil erosion and improving soil fertility. NT and RT may improve the environmental and economic performance of organic farming, but they are still not common practice among organic farmers. This paper presents the effects of tillage [RT versus conventional tillage (CT)], fertilization (slurry versus manure compost) and biodynamic preparations (with versus without) on soil fertility indicators such as soil organic carbon (Corg), microbial biomass and microbial activity, soil nutrients and nutrient budgets in an organic farming system during the first six-year crop rotation period of a long-term experiment on a clayey soil in a temperate climate.

Autores: Koopmans, C.J.; Zanen, M.
Understanding organic management practices is a key in developing sustainable organic farming systems. We report the results of four different organic fertilization strategies in a field trial on yields, soil quality and economic performance. We found highest yields and economic performance in two direct plant feeding strategies. One of these strategies, a newly developed strategy based on biowaste compost (GFT) and an additional fertilizer performed well in terms of yields but looks also very promising in terms of soil quality and biodiversity. The economic perspective of this strategy renders it promising in regions with little animal manures.

Karbon i jord – kilder, handtering og omdanning
Provedor de dados: 21
Autores: Serikstad, Grete Lene; Pommeresche, Reidun; McKinnon, Kirsty; Hansen, Sissel.
Rapporten omfatter en gjennomgang av kunnskap om handtering, omdanning og lagring av karbon i jord. Klima, jordtype, driftsmåte, tilført organisk materiale og opprinnelig karboninnhold har betydning for karbonbindingen i jord, noe som gjør det umulig å generalisere det potensialet jord har til å binde karbon over lengre tid. Litteraturgjennomgangen viser at det ikke er enkelt å lagre karbon i dyrkajord. I rapporten diskuteres virkning av fermentering og kompostering på karbonbinding. Rapporten påpeker nødvendigheten av å vektlegge kvaliteten av det organiske materialet som skal tilføres jorda. Biokull kan brukes for lagring av karbon i jord. Positive egenskaper knyttet til jordforbedring kan bidra til at biokull tilført jordbruksarealer blir aktuelt som...

Åbent Hus: Forbedret udnyttelse af jord og ressourcer i økologiske dyrkningssystemer
Provedor de dados: 21
Autores: Kristensen, Helene.
Projektet SoilVeg handler om forbedret udnyttelse af jord og ressourcer i økologiske dyrkningssystemer for grøntsager med grønafgrøder. Der afprøves dyrkning af hvidkål i to nye dyrkningssystemer med reduceret jordbearbejdning. I det ene system plantes direkte ned i en tromlet vintergrønafgrøde uden anden jordbearbejdning, og her er det tanken at den tromlede biomasse dækker jorden og dermed holder ukrudt nede i løbet af sæsonen. I det andet system laves stribenedmuldning af grønafgrøden før plantning. De to nye systemer sammenlignes med almindelig nedmuldning og ingen forudgående grønafgrøde. Både vinterhestebønne, vinterært og vintervikke er blevet brugt som grønafgrøder og i blandinger med vinterrug. Disse forsøg kører ved Forskningscenter Årslev i 2016...

Verwerken van maaisel voor landbouwkundig gebruik: Waarde van compost,bokashi en bermgraskuil als meststof
Provedor de dados: 21
Autores: Janmaat, Leen.
Gewasresten van het landbouwbedrijf en maaisel uit beheersgebieden vormen reststromen die geschikt zijn als organische meststof. Deze reststromen kunnen als input voor composteren worden gebruikt. Bij composteren verdwijnt een deel van de organisch gebonden koolstof naar de lucht. Een alternatief is het fermenteren en conserveren van maaisel en andere inputs is het zogenaamde Bokashi-methode. Bokashi betekent “goed gefermenteerd organisch materiaal”. Met behulp van micro-organismen, zeeschelpenkalk en kleimineralen wordt het fermentatieproces in werking gezet.Het fermenteren vindt plaats onder zuurstofloze omstandigheden. In Noord-Holland zijn experimenten gedaan met het bereiden van Bokashi en die zijn vergeleken met compost. De waarde van Bokashi kan...

Above- and belowground nitrogen distribution of a red clover-perennial ryegrass sward along a soil nutrient availability gradient established by organic and conventional cropping systems
Provedor de dados: 21
Autores: Hammelehle, Andreas; Oberson, Astrid; Lüscher, Andreas; Mäder, Paul; Mayer, Jochen.
Aims  Belowground legume nitrogen (N) composed of roots and rhizodeposition is an important N input to soils, but published data of belowground N vary broadly, probably due to extrapolation from short-term experiments and dissimilar growing conditions. We quantified belowground N inputs of red clover (Trifolium pratense L.) during two consecutive years in a clover-grass sward along a soil nutrient availability gradient.  Methods  We established a red clover-perennial ryegrass (Lolium perenne L.) model sward in microplots located in field plots of the DOK experiment, which has a 33-year history of organic and conventional cropping, resulting in a soil nutrient availability gradient. Four treatments were examined: the zero fertilisation control, bio-organic...

DOC trail: soil organic matter quality and soil aggregate stability in organic and conventional soils
Provedor de dados: 21
Autores: Fliessbach, Andreas; Hany, Roland; Rentsch, Daniel; Frei, Robert; Eyhorn, Frank.
Conclusion  Soil organic matter quality is affected by the agricultural systems of the DOC trial. System effects on the chemical composition, however, were smaller than those on the living organisms in soil and their functions. A close correlation was found between soil structure and microbial biomass indicating that microbes are playing an important role in soil structural stability.

A importância das áreas ripárias para a sustentabilidade hidrológica do uso da terra em microbacias hidrográficas.
Provedor de dados: 21
Autores: Attanasio, Cláudia Mira; Gandolfi, Sergius; Zakia, Maria José B.; Veniziani Junior, José Carlos Toledo; Lima, Walter de Paula.
Zonas ripárias são áreas de saturação hídrica, permanente ou temporária, cuja principal função é a proteção dos recursos hídricos de uma microbacia. Essa pesquisa comparou a adequação do uso do solo de dois cenários de planejamento agrícola de uma microbacia: o cenário convencional, representando o método usualmente empregado, que apenas considera as classes de capacidade de uso da terra, e o cenário hidrológico, que inclui a delimitação e avaliação das zonas ripárias. Um estudo de caso foi realizado na Microbacia do Ribeirão São João (3.656 ha), no município de Mineiros do Tietê (São Paulo, Brasil). Mapas de Classe de Capacidade de Uso da Terra e de Adequação do Uso do Solo foram elaborados, utilizando o Sistema de Informação Geográfica (SIG), para a...

Development of SOM and aggregation in an agriculturally managed re-cultivated loess
Provedor de dados: 21
Autores: Pihlap, Evelin; Steffens, Markus; Kögel-Knabner, Ingrid.
Soil organic matter (SOM) and organic glues from biological processes are considered to be major contributors inaggregate formation. But there is limited knowledge on soil structural formation during initial soil development –the step when SOM content is low and soil properties are mostly controlled by the parent material. In our study we used a chronosequence approach in the re-cultivated open-cast mining area near Cologne, Germany to elucidate thedevelopment of soil structure and soil organic matter during initial soil formation in a loess material. We selectedsix plots with different ages of agricultural management after re-cultivation (0, 1, 3, 6, 12, and 24 years after firstseeding). In each plot 12 spatially independent locations were sampled with...

Provedor de dados: 21
Autores: Lori, Martina; Symanczik, Sarah; Mäder, Paul; de Deyn, Gerlinde; Gattinger, Andreas.
Population growth and climate change challenge our food and farming systems and provide arguments for an increased intensification of agriculture. A promising option is eco functional intensification through organic farming, an approach based on using and enhancing internal natural resources and processes to secure and improve agricultural productivity,  while minimizing negative environmental impacts. In this concept an active soil microbiota plays an important role for various soil based ecosystem services such as nutrient cycling, erosion control and pest and disease regulation. Several studies have reported a positive effect of organic farming on soil health and quality including microbial community traits.  However, so far no systematic quantification...

Effects of reduced tillage on soil organic carbon and microbial activity in a clayey soil
Provedor de dados: 21
Autores: Berner, Alfred; Fliessbach, Andreas; Nietlisbach, Bruno; Mäder, Paul.
In a long-term field trial recently launched (2002-2011), located in Frick (878 mm mean annual precipitation) near Basle, Switzerland, the effect of reduced tillage on soil fertility indicators and crop yield was studied in a heavy soil (45% clay) in a crop rotation under organic farming conditions. We present the results of soil analyses after three cropping years (2002-2005). Soil organic carbon (Corg) increased over that period by 7.4% (+1.5 g Corg kg-1 soil) in the 0-10 cm soil layer in the reduced tillage plots, while it remained constant in the ploughed plots. Soil microbial carbon (Cmic) and dehydrogenase activity (DHA, TTC-reduction) were 28% higher in reduced-tillage plots in this soil layer. Biological soil quality as calculated by Cmic to Corg...

Symbiotic nitrogen fixation and N-transfer in a grass-white clover mixture
Provedor de dados: 21
Autores: Vinther, Finn P.
Symbiotic N2 fixation (SNF) and transfer of fixed N from clover to grass in a grass-white clover mixture was measured during two years using 15N isotope dilution techniques. White clover derived from 87 to 99% of its N from the atmosphere. The total SNF ranged from 150 to 277 kg N ha-1 yr-1, which corresponded to 34-45 mg N fixed per gram of white clover dry weight. The transfer of fixed N from clover to grass corresponded to approximately 10 kg N ha-1 yr-1.

Autores: Möller, Kurt.
Phosphorus (P) is an essential element for all living organisms, and at the current rate of extraction, global reserves will be exhausted in the next few centuries. Often, P balances calculated for organically managed arable systems indicate that more P is removed with the products than applied as fertilizer. Within the IMPROVE-P consortium, the relative P fertilizer effectiveness of most recycling P fertilizers was assessed. Most organic P fertilizers with exception of meat and bone meal have a relatively high relative P effectiveness. Struvite obtained from chemical approaches for P recycling also showed high P effectiveness, while incineration and most other thermal approaches downgraded the final fertilizer value by the loss of organic matter, nitrogen...

Autores: Lagomarsino, A.; Agnelli, A.E.; Fulchin, E.; Giffard, B.
Soil enzymes were used to assess the impact of different treatments applied in four farms, each one with three vineyards as replicates, on soil functionality. 8 enzymes related to C, N, S and P cycling were measured and functional diversity indexes were estimated. Three treatments were compared: compost, green manure and dry mulching with respect to degraded and non-degraded soil. The four vineyards showed different enzymatic patterns and response to treatments. Vineyards with the largest difference between degraded and non-degraded soil have benefited more largely from the treatments. In particular, dry mulching seemed to be more effective than green manure or compost, with the exception of San Disdagio. However, the effect the short term.

Land management aiming to sustain ecosystem services is an important issue, especially in biodiversity hot spots such as found in Mediterranean areas. In Mediterranean areas, viticulture is an important land use. Vineyards are frequently found on inherently poor soils and are submitted to intensive management practices, which threaten soil functioning and associated ecosystem services. To encourage winegrowers and stakeholders to be reflective and adapt their vineyard practices, we evaluated the effects of three soil management practices (inter row plant cover duration, weeding and fertilization strategies) on soil functioning in 146 commercial plots distributed in Southern France, by a complementary set of biological and physico-chemical indicators.

SoilVeg - "Improving soil conservation and resource use in organic cropping systems for vegetable production through introduction and management of Agro-ecological Service Crops”
Provedor de dados: 21
Agro-ecological Service Crops (ASC) are introduced in the agro-ecosystems to provide or enhance ecological services, thus promoting the whole soil-plant system equilibrium. ASC introduction and proper management have impact on soil quality and fertility and soil nutrients losses. They also contribute to increase soil C sink potential, to mitigate GHG emissions and influence weeds, diseases and pests occurrence. To avoid competition with the subsequent cash crops, the growth of the interposed ASC is terminated in advance of the cash crop planting. The traditional, most widespread, technique used to terminate the ASC is incorporation as green manure into the soil by tillage. However, since tillage is an energy and labour consuming and soil disturbing...

Application of processed organic municipal solid waste on agricultural land - a scenario analysis
Provedor de dados: 21
Autores: Bruun, Sander; Hansen, Trine L.; Christensen, Thomas H.; Magid, Jakob; Jensen, Lars S.
Source separation, composting and anaerobic digestion, with associated land application, are increasingly being considered as alternative waste management strategies to landfilling and incineration of municipal solid waste (MSW). Environmental life cycle  assessments are a useful tool in political decision-making about waste management strategies. However, due to the diversity of processed organic MSW and the situations in which it can be applied, the environmental impacts of land application are very hard to determine by experimental means. In the current study, we used the agroecosystem model Daisy to simulate a range of different scenarios representing different geographical areas, farm and soil types under Danish conditions and legislation. Generally,...

Effect of conventional and organic cropping systems on SOC dynamics
Provedor de dados: 21
Autores: Tein, Berit; Kauer, Karin; Eremeev, Viacheslav; Luik, Anne; Loit, Evelin.
Soil organic carbon (SOC) concentration is an indicator for assessing soil quality. SOC concentration can be increased by using appropriate crop and soil management which can  increase organic matter input into soil and decrease its mineralization rate (Follett, 2001). The aim of this study was to investigate SOC content and dynamics in four inorganic and two organic cropping systems in five crop rotation. Data presented in this paper covers the first rotation from  years 2008 to 2012.

Autores: Munkholm, L.J.
Mange års pløjning med traktorhjulet i furebunden samt færdsel med tunge maskiner har betydet, at skadelig pakning af underjorden er et udbredt og tiltagende problem i Danmark. Undersøgelser ved Danmarks JordbrugsForskning viser, at stort set alle danske jorde har et fortættet jordlag under pløjedybden - en såkaldt pløjesål. Mange steder er jorden også pakket længere ned som følge af kørsel med tunge maskiner. Alt andet lige er skadelig pakning et alvorligt problem under økologiske dyrkningsforhold, hvor det vigtigt at bibeholde og fremme en velfungerende og sund jord.  Der findes en bred vifte af redskaber, der forholdsvis effektivt løsner en pakket underjord, hvis løsningen vel at mærke foretages under tørre forhold. Alligevel viser de fleste forsøg, at...

mechanisatie in dienst van bodembeheer
Provedor de dados: 21
Autores: Balen, Derk van.
Onbereden teeltbedden hebben bewezen een hogere opbrengst te kunnen geven in een groot aantal gewassen. Vooral structuurgevoelige gewassen zoals bladgewassen (spinazie) kunnen hiervan profiteren. Doordat er in principe niet meer over de teeltbedden gereden wordt, kan de bodemstructuur  in stand blijven of zich gemakkelijk herstellen.  Jammer genoeg is de oogstmechanisatie nog niet passend voor de onbereden teeltbedden.  Tot aan de oogst wordt er niet over de bedden gereden en zelfs dit heeft al een effect op de bodemstructuur. Door te kiezen voor een laag gewicht van de oogstmachines ontzien we de bodemstructuur.

Qualité des sols viticoles en Languedoc Roussillon : effets des pratiques
Provedor de dados: 21
Autores: Coll, Patrice.
Le sol, composante du Terroir doit être considéré comme une ressource non renouvelable essentielle au fonctionnement des agro‐écosystèmes. Or, les sols viticoles sont particulièrement vulnérables aux dégradations. L’objectif central de ma thèse est donc d’évaluer comment les pratiques viticoles affectent la qualité des sols dans le Languedoc‐Roussillon. Pour ce faire, j’ai d’abord évalué la qualité des sols sur 164 parcelles présentant une grande variabilité de pratiques culturales et réparties sur 9 zones pédologiques très diversifiées. Puis, j’ai évalué la vitesse de changement de la qualité des sols par l’analyse de 23 parcelles d’une zone homogène converties progressivement en viticulture biologique depuis un maximum de 17 ans.

Properties and functions of organic materials in poor agricultural soil condition
Provedor de dados: 21
Autores: Usman, Suleiman.
A field experiment was conducted under different soil  strata in poor agricultural soil condition. Each soil stratum was treated separately with different organic material for soil fertility management. These organic materials are cow dung, sheep dung, goat dung, donkey dung, rice husks, millet husks, Acacia albida, Acacia nilotica, wood ash, house refuses, and combination of all ‘ani-cro-ber’. In the first assessment, soil structure, texture, colour, consistency, bulk density were determined in the field, while in the second assessment N, P, K, Na, Ca, OC, OM and pH were determined under specific laboratory analysis. It is believed that the use of organic materials in soil management is a good way to improve and maintain soil quality and soil fertility...

Knowledge about the role of microorganisms in P cycling at conditions of constant soil respiration rates and constant size of microbially bound P is lacking. To study the kinetics of microbial P uptake and cycling under such conditions, soils differing in biological activity were 33PO4 labelled by introducing a carrier-free tracer solution and incubated for 56 days. The 33PO4 incorporation into the fraction of microbial P releasable by chloroform treatment (Pchl) was assessed and the isotopic composition [=specific activity (SA); SA=33PO4/31PO4] of Pchl and soil solution P compared. Soils were taken from a 20-year-old field experiment including a nonfertilised control (NON), a minerally fertilised conventional (MIN) and two organic farming systems...

Grassland carbon sequestration and emissions following cultivation in a mixed crop rotation
Provedor de dados: 21
Autores: Acharya, B.S.; Rasmussen, J.; Eriksen, J.
Grasslands are potential carbon sinks to reduce unprecedented increase in atmospheric CO2. Effect of age (1 to 4-yr-old) and management (slurry, grazing multispecies mixture) of a grass phase mixed crop rotation on carbon sequestration and emissions upon cultivation was compared with 17-yr-old grassland and a pea field as reference. Aboveground and root biomass were determined and soils were incubated to study CO2 emissions after soil disturbance. Aboveground biomass was highest in 1-yr-old grassland with slurry application and lowest in 4-yr-old grassland without slurry application. Root biomass was highest in 4-yr-old grassland, but all 1 to 4-yr-old grasslands were in between the pea field (0.81±0.094 g kg-1 soil) and the 17-yr-old grassland (3.17±0.22...

Nitrogen efficiency in organic farming using a GPS precision farming technique
Provedor de dados: 21
Autores: Zanen, Marleen; Koopmans, Chris.
In the coming years, agriculture in the Netherlands will be forced to produce more high quality produce with smaller inputs of fertilisers. Organic agriculture should play a leading role and set an example for sustainable soil management. This implies greater nutrient use efficiency and fewer inputs. GPS-controlled precision tillage using the same tracks in the field year after year offers the opportunity to improve soil structure. The tracks become compacted, improving trafficability (Vermeulen &amp; Klooster, 1992). Our hypothesis is that the soil structure of the remaining beds will improve, providing better aeration and rooting for the crop and access to necessary nutrients. This would mean that nutrient use efficiency would improve in GPS-controlled...

Spontaneous cover cropping is a common practice in Mediterranean vineyards because it is often seen as less competitive and easier to manage than sown covercrops. However, the services provided by the spontaneous flora highly depend on the species, these latter being influenced by the soil management practices. This study analyzes the specific and functional composition of the vineyard flora as influenced by three soil management strategies. To do so, weed cover was sampled at 5 dates during two years after the settlement of the experiment in a vineyard in the South of France. The three soil management treatments were: a control treatment (C) corresponding to a spontaneous cover regularly mowed, a spontaneous cover with organic amendment application each...

Land transformation to adapt fields to mechanization in perennial crop farming is a common practice which includes land levelling, deep ploughing, stone-breakage and clearing, application of fertilizers and amendments. Manipulation of the natural soil profile along its entire depth can severely disturb the naturally existing chemical  physical,biological and hydrological equilibrium (Costantini and Barbetti, 2008; Costantini et al., 2013). The most common effects of the land transformation are mixing of soil horizons and soil truncation, which result in reduction of soil depth and available water, organic matter depletion, enrichment of calcium carbonate content in the topsoil,imbalance of some element ratio, and decline in the activity and diversity of...

Improving Soil Structure and Nitrogen Use Efficiency by GPS-controlled Precision Tillage Technology in Organic Farming
Provedor de dados: 21
Autores: Zanen, Ir. M.; Koopmans, Dr. Ir. C.J.
A field experiment was conducted to determine the effects of tillage technique (GPS-controlled traffic system and traditional tillage) and level of fertilization (farmers’ practice or phosphate equilibrium) on yield, soil structure and nitrogen use efficiency. Manure inputs could be seriously reduced without yields being diminished during the first three years of the intensive crop rotation. Results suggest that an improved soil structure under GPS-controlled precision tillage enhances nitrogen use efficiency.

Farmyard manure, plant based organic fertilisers, inorganic fertiliser - which sustains soil organic matter best?
Provedor de dados: 21
Autores: Raupp, Joachim; Oltmanns, Meike.
Legume biomass or pulse meal may be considered as alternatives to farmyard manure (FYM) in organic farms with small scale animal husbandry or in stockless organic farms. From 1996 a field trial was established on a poor sandy soil to compare plant based organic fertilisers, FYM and inorganic fertilisers, each applied at 100 kg ha-1 N. Additionally, FYM was tested at a higher rate of 170 kg ha-1 N. Average soil organic carbon content in topsoil (Corg) of the last crop rotation period (2002-05) is compared to that in 1996. Corg remained at the same level of 0.78 % only with FYM, while plant based and inorganic fertiliser decreased carbon contents to 0.74 and 0.72 % Corg, respectively. The higher FYM rate increased Corg up to 0.84 %. Based on these results,...

This webinar is about Cover crops. They are an integral part of all organic cropping systems since they provide the foundation for organic nutrient management, pest control, weed suppression, and improving soil health. Andy Bary, Washington State University – Puyallup, explains the different classes of cover crops and the benefits each class provides. He also introduces the concept of “inter-seeding relay planting” or the growing of one crop planted between the rows of an existing crop, e.g. hairy vetch planted into corn. He discusses seeding techniques, species selection, and management strategies to ensure success. Weed suppression using summer cover crops is also discussed. The webinar is targeted both to newcomers and experienced organic farmers.

Organic matter addition in organic farming – Impact on root development and yields in maize and cowpea over dry seasons
Provedor de dados: 21
Autores: Sangakkara, Dr Ravi; Bandaranayake, Mr P; Dissanayake, Ms U; Gajanayake, Ms J.
Organic matter and its proper management are vital in tropical organic farming to maintain productivity. A field study thus placed rice straw or Gliricidia leaves on the soil surface or the material was incorporated into soil. The impact of these treatments on soil moisture, root development and yields of organically grown maize or cowpea were evaluated in an Asian dry season. Incorporation increased soil moisture retention in the soil and hence induced better root growth, culminating in higher yields. The impact was greater in maize, especially with Gliricidia leaves. The benefits of incorporating organic matter in dry seasons for tropical organic farming are presented.

Physical fractionation of soil and structural and functional complexity in organic matter turnover
Provedor de dados: 21
Autores: Christensen, B.T.
Physical fractionation is used increasingly to study the turnover of organic matter in soil.  This essay links the methods of fractionation to concepts of turnover by defining levels of structural and functional complexity that refer to experimentally verifiable pools of organic matter in the soil.   Physical fractionation according to size and density of soil particles emphasizes the importance of interactions between organic and inorganic soil components in the turnover of organic matter.  It allows the separation of free and occluded uncomplexed organic matter and of primary and secondary organomineral complexes.  This methodological approach recognizes that the overall regulation of decomposer activity is through the structure of soil, which determines...

Provedor de dados: 21
Autores: Hospers-Brands, A.J.T.M.; Strien, J. van.
Dit rapport bevat de resultaten van het vierde jaar van het project "Bedrijfsinterne Optimalisatie", en wel van het deelproject "Van Strien". Op diverse percelen zijn metingen uitgevoerd aan de bodem om de stikstof werking van maaimeststoffen in beeld te krijgen. Op perceel 1A (aardappelen in 2014) heeft de strook met maaimeststoffen 2,3 maal zo veel stikstof gekregen als de bedoeling was, als gevolg van een twee maal zo hoog drogestofgehalte als vooraf was ingeschat. Dit was echter niet terug te vinden in de gemeenten hoeveelheden N-mineraal in de bodem en in de gehele strook met maaimeststoffen was de opbrengst lager dan bij de standaard bemesting. Door een vroege Phytophthora aantasting moest er vroeg gebrand worde. Daardoor waren de opbrengsten zeer...

Organic farmers grow grassclover in nature areas to remove soil phosphate for development of specious rich grasslands
Provedor de dados: 21
Autores: Timmermans, B.G.H.; Eekeren, N. van.
While worldwide the current reserves of phosphate rock are being exhausted, many agricultural and former agricultural soils in The Netherlands have been enriched by large quantities of phosphorus as a result of fertilization. In current nature development projects on former agricultural lands, it is thought that this phosphorus prevents development of target-nature types. Therefore nature organizations currently seek ways to remove it. We tested grassclover, organically managed by local farmers, as a tool to extract excessive soil phosphate from nature areas and reimport it into the mineral cycle agricultural farms.  In a small scale experiment we have shown that grassclover with potassium fertilization can remove more than twice the amount of soil...

Microbial Community Structure and Litter Decomposition in Stratified Soils of a Long Term Reduced Tillage Experiment
Provedor de dados: 21
Autores: Suhadolc, M.; Baškovč, M.; Kaurin, A.; Kastelec, D.; Mihelič, R.
The aim of the present study was to examine decomposition of plant material (maize straw, green and rooibos tea) in stratified soils of the long-term tillage experiment, established in 1999 and shifted from conventional to organic farming system in 2015.    The plowing in conventional tillage (CT) has been done by moldboard plow 20 cm deep, while in minimum tillage (MT), soil disturbance has been up to 10 cm deep by a Special disc harrow. More than 15 years of long term Minimum tillage, with reduced soil disturbances and improved residue management, resulted in stratification of soil organic carbon and nutrients with highest concentrations in the very topsoil.

Einfluss von Pseudomonas fluorescens auf Ertrag von Weizen  und mikrobielle Biomasse des Bodens
Provedor de dados: 21
Autores: Fließbach, Andreas; Mäder, Paul.
P. fluorescens is used in agriculture and horticulture as a plant growth promoting  rhizobacterium. It colonizes root surfaces effectively and excretes compounds that are  influencing plant nutrient uptake and plant health. Soils with different initial biological  fertility were analysed 18 and 60 days after inoculating the freshly sown wheat plants  with a suspension of a rifampicine tolerant strain of P. fluorescens CHA0, in order to  evaluate its survival and lasting effect on soil microbial biomass. P. fluorescens had a  lasting effect in soils with low initial biomass, but no lasting effects were found in  biologically active soils.

A.; Willekens, Koen; Wittwer, Raphaël; Mäder, Paul.
Reduced tillage is increasingly promoted to improve sustainability and productivity of agricultural systems. Nonetheless, adoption of reduced tillage by organic farmers has been slow due to concerns about nutrient supply, soil structure, and weeds that may limit yields. Here, we compiled the results from both published and unpublished research comparing deep or shallow inversion tillage, with various categories of reduced tillage under organic management. Shallow refers to less than 25 cm. We found that (1) division of reduced tillage practices into different classes with varying degrees of intensity allowed us to assess the trade-offs between reductions in tillage intensity, crop yields, weed incidence, and soil C stocks. (2) Reducing tillage intensity in...

Autores: Mäder, Paul; Berner, Alfred; Fließbach, Andreas; Messmer, Monika; Koller, Martin; Weibel, Franco; Stolze, Matthias; Schader, Christian; Sanders, Jürn; Dierauer, Hansueli; Clerc, Maurice.
Die Landwirtschaft trägt weltweit mit 12–32 Prozent zum Klimawandel bei. Hauptquellen sind der Methanausstoss der Wiederkäuer, der CO2-Verbrauch für die Herstellung von Düngern und Pestiziden, die Abholzung von Wäldern für den Ackerbau und Weideflächen sowie die Bodenerosion. Auch der Einsatz des Pflugs verbraucht viel Energie, verstärkt den Abbau von Humus und belastet somit das Klima.  Gemäss bisherigen Untersuchungen benötigt die biologische Landwirtschaft schon heute mit den gängigen Methoden weniger Energie als die konventionelle Bewirtschaftung.  Im DOK-Versuch zum Beispiel verbrauchen die Bioverfahren 20 Prozent weniger Energie pro Ertragseinheit. Dies macht den Biolandbau zwar klimafreundlicher, aber noch nicht klimaneutral.

Residual effects of previous crops on soil respiration, nitrogen mineralisation and N2O emission

Autores: Vinther, F.P.; Olesen, J.E.
Models for simulating nitrogen leaching are often based on simulations of a number of individual processes in the soil, such as turnover of organic matter, nitrogen mineralisation and immobilisation, nitrification, denitrification etc. It has been found that the models used under Danish conditions (DAISY and/or FASSET) have some limitations especially concerning the turnover of organic matter with implications on e.g. soil respiration. Therefore, the models are being modified and for calibration of the model measurements of in situ soil respiration using a portable CO2-analyser, nitrogen mineralization using a field incubation technique and N2O emission using a static chamber method, were carried out during the growing season 2001. The measurements were...

Long-Term Management Affects the Community Composition of Arable Soil Seedbanks
Provedor de dados: 21
Autores: Rotchés-Ribalta, Roser; Armengot, Laura; Mäder, Paul; Mayer, Jochen; Sans, Francesc Xavier.
The intensification of farming practices has reduced weed infestations, but it has also led to a reduction in weed diversity and changes in species composition. These effects are well described for aboveground flora; however, it is less clear how these effects might be expressed in the soil weed seedbank. We evaluated the effects of different long-term farm management strategies on the weed seedbank abundance, diversity, and community composition in the DOK (bioDynamic, bioOrganic, and Konventionell) field trial established in 1978 at Therwil, Switzerland. The trial compares biodynamic, organic, and conventional farming systems, which mainly differ in fertilization, weed control strategies, and pest control. The species richness and seed abundance of the...

Learning how to manage beneficial soil biological processes may be a key step towards developing sustainable agricultural systems. We designed a conceptual framework linking soil management practices to important soil-life groups and soil fertility services like nutrient cycling, soil structure and disease suppression. We selected a necessary parameter set to gain insight between management, soil life and soil support services. The findings help to develop management practices that optimise yields, soil fertility and  biodiversity in organic farming.

Few recurring types of microdomains define smallest units of soilfunctioning
Provedor de dados: 21
Autores: Steffens, Markus; Rogge, Derek; Höschen, Carmen; Lugmeier, Johan; Mueller, Carsten W.; Kögel-Knabner, Ingrid.
Soil aggregation is a key factor for a number of important biogeochemical processes (e.g. soil organic matter stabilization and nutrient and pollutant sorption) in soils. Although there is a large number of studies on the factors controlling such soil processes, it is still challenging to study these processes in-situ. However, it can be assumedthat the spatial arrangement of organic and mineral soil constituents in soil aggregates, and thus the aggregate structure determine the processes happening at the aggregate scale. Using nanoscale secondary ion mass spectroscopy and a novel digital image processing approach, we extensively analyzed the spatial distribution of ions characteristic for mineral and organic soil components on the micrometer-scale in an...

A study was carried out in nineteen vineyards of five countries, well representative of major viticultural districts, which showed areas with fertility problems, consequence of strong soil erosion occurred during either pre-planting or ordinary cultivation. The comparison between degraded and non-degraded areas highlighted that the soil features limiting water nutrition and enhancing potential water stress were the most frequent discriminant soil conditions. Low nitrogen availability was the second most important cause of soil malfunctioning, together with low organic matter content. The degradation was also reflected in the very low values of the C/N ratio, pointing to a difficulty of microbiota in synthetizing humus. Other limiting factor were excessive...

Biological processes dominate phosphorus dynamics under low phosphorus availability in organic horizons of temperate forest soils
Provedor de dados: 21
Autores: Pistocchi, Chiara; Mészáros, Éva; Tamburini, Federica; Frossard, Emmanuel; Bünemann, Else Katrin.
Understanding the mechanisms underlying phosphorus (P) availability is important to predict forest productivity in a changing environment. We quantified P fluxes and traced P from plant litter into inorganic and organic soil P pools in organic horizons from two contrasting temperate forest soils with low and high inorganic P availability, respectively. We incubated the two organic horizons with and without litter after labelling the soil solution with 33P and performed sequential extractions at several time points in order to trace P dynamics in labile (water-extractable, available and microbial P) and non-labile (non-living organic P, P bound to iron and aluminium and P bound to calcium) pools. Under low P availability, P fluxes were dominated by gross P...

Autores: Koopmans, Chris; Rietberg, P.I.; Burgt, G.J.H.M.
The NDICEA model was used to simulate and evaluate field trials, designed to improve organic cropping system by using reduced tillage and green manures. The model can help to assess whether nitrogen shortages are likely to occur, and to evaluate the effect of green manure and reduced tillage conditions on nitrogen dynamics and soil organic matter pools.  To investigate the effects of tillage and nutrient management on N cycling and soil organic matter pools using the model NDICEA for different experimental sites across Europe. In addition adaptations to the NDICEA model are proposed to cover the effects of reduced tillage in these computer simulations.

Crop yield and soil fertility response to reduced tillage under organic management
Provedor de dados: 21
Autores: Berner, Alfred; Hildermann, Isabell; Fliessbach, Andreas; Pfiffner, Lukas; Niggli, Urs; Mäder, Paul.
Conservation tillage (no-till and reduced tillage) brings many benefits with respect to soil fertility and energy use, but it also has drawbacks regarding the need for synthetic fertilizers and herbicides. Our objective was to adapt reduced tillage to organic farming by quantifying effects of tillage (plough versus chisel), fertilization (slurry versus manure compost) and biodynamic preparations (with versus without) on soil fertility indicators and crop yield. The experiment was initiated in 2002 on a Stagnic Eutric Cambisol (45% clay content) near Frick (Switzerland) where the average annual precipitation is 1000 mm. This report focuses on the conversion period and examines changes as tillage intensity was reduced. Soil samples were taken from the 0-10...

Collembola in grassland – included in the new project SoilEffects
Provedor de dados: 21
Autores: Pommeresche, Reidun; Løes, Anne-Kristin.
Little is known about Collembola in arable soil, at least in Norway. Recently, a study including this group has been initiated in a Norwegian field experiment Soileffects).  Collembola (springtails) are a group of small animals (1-3 mm) living in vegetation,litter and in the pores and caves in the soil to a depth of ca 15 cm. They are important decomposers of dead plant material, eating fungi, algae and  microorganisms in soil and on organic debris. Their grazing and decomposing activity contribute significantly to the nutrient circulation in the soil. The name springtail refers to a furca on their back, usually folded in under the body, but released in need of a rapid escape. In one jump, Collembola can jump more than 50 times their own body length. In...

Basal organic phosphorus mineralization in soils under different farming systems
Provedor de dados: 21
Autores: Oehl, F.; Frossard, E.; Fliessbach, A.; Dubois, D.; Oberson, A.
Soil organic P (Po) mineralization plays an important role in soil P cycling. Quantitative information on the release of available inorganic P (Pi) by this process is difficult to obtain because any mineralized Pi gets rapidly sorbed. We applied a new approach to quantify basal soil Po mineralization, based on 33PO4 isotopic dilution during 10 days of incubation, in soils differing in microbiological activity. The soils originated from a 20 years old field experiment, including a conventional system receiving exclusively mineral fertilizers (MIN), a bioorganic (ORG) and bio-dynamic (DYN) system. Indicators of soil microbiological activity, such as size and activity of the soil microbial biomass and phosphatase activity, were highest in DYN and lowest in...

Effects of applying anaerobically digested slurry on soil available organic C and microbiota
Provedor de dados: 21
Autores: Johansen, A.; Pommeresche, R.; Riley, H.; Løes, A.-K.
Anaerobic digestion of animal slurries and plant residues is a valuable technology to produce bioenergy and fertilizers in organic farming systems, while at the same time reducing propagules of weeds and parasites in the input material. However, the digestion changes the quality of the slurry by reducing its content of organic matter and increasing mineral nitrogen (N) levels. This may have profound impact on soil fauna and microorganisms as well as the biogeochemical processes they drive. Organic farmers fear that application of digested materials may have negative implications for soil fertility by reducing the input of organic matter to the soil, compared to fertilizing with traditional animal slurries or green manures. Hence, it is important to gain...

Stepwise incorporation of white clover (Trifolium repens L.)as fertiliser increases nitrogen fixation and improves nitrogen retention when intercropped with leek (Allium porrum L.)
Provedor de dados: 21
Autores: Xie, Yue; Sørensen, Jørn Nygaard; Petersen, Karen Koefoed; Kristensen, Hanne Lakkenborg.
Background and aims  We investigated whether the incorporation of intercropped white clover as a split-dose fertiliser improves N retention of the plant-soil system in leek production.    Methods  White clover and leek were grown in pots where clover was stepwise incorporated into soil as fertiliser. Half of the clover was incorporated before leek transplantation (LT), the other half was incorporated 26 (S1) or 41 (S2) days after LT, compared with full incorporation of all clover (F) before LT. 15N injection and leaching studies were performed to investigate interspecific competition and the effects of precipitation on soil N availability.    Results  Stepwise incorporations increased or had no effect on leek growth, despite competition for N between white...

Autores: Manojlovic, M.; Cabilovski, R.; Kalentic, M.
The aim of this study was to examine on-farm the influence of organic farming systems on soil fertility, in order to recommend agrotechnical practices that will contribute to increase soil fertility, thus the yield and quality of cultivated plants. The survey was conducted at 7 representative farms in the system of control and certification in Vojvodina, northern Serbia, and within them, 55 production fields with different history of farming practices. Optimal to high soil fertility found in average in all investigated sites indicates that there are necessary natural preconditions for successful organic farming. The results showed high variability in soil fertility, both, between organic farming systems and between different sites. Significant differences...

Searching the critical soil organic carbon threshold for satisfactory tilth conditions – test of the Dexter clay:carbon hypothesis
Provedor de dados: 21
Autores: Schjønning, P.; de Jonge, L.W.; Moldrup, P.; Christensen, B.T.; Olesen, J.E.
The concern for deteriorating soil structure at low soil organic matter (SOM) contents calls for better knowledge of SOM interaction with soil minerals as well as guidelines for soil conservation. We measured clay dispersibility in a field with a textural gradient. Our results support the concept of differentiating soil content of clay in a complexed and non-complexed part although our data did not point out an exact clay/OC ratio threshold. Our results also indicated that labile fractions of SOM may play an important role in soil physical behavior. We revisited literature data and found evidence that soil content of fines (&lt;2 or &lt;20 μm) is a major determinant of soil specific surface area (SA). We noted that soil SA coverage with SOM changed...

Maintaining sufficient soil phosphorus (P) levels for non-limiting crop growth is challenging in organic systems since off-farm inputs of P are restricted. This study assessed the status of P on organic farms in Europe using soil test results for extractable P. Data was obtained from published literature, unpublished theses, and various national and regional databases of soil test values. Most of the data (15,506 observations) came from field scale soil tests, but in some cases (1272 observations) values had been averaged across a farm. Farm scale and field scale data were analysed separately and the impact of farm type (arable, dairy, grassland, horticulture, mixed, poultry, unknown) was assessed. Soil test results were assigned to P classes from very low...

Conservation practices are important in improving the environmental protection of agroecosystems in semiarid regions, as these are considered to be fragile environments. Soil-quality indicators are useful elements in evaluating the impact of some agricultural management practices, and the use of recognized indicators which are able to be measured by farmers is an innovative approach that seeks to integrate both scientific and local knowledge. This study aimed to evaluate the impact of various management practices through indicators of soil quality related to soil structure, in areas of family farming where agroecological consortiums are employed. These indicators were identified as important by the farmers themselves, and methodologies were suggested for...

Autores: Munkholm, Lars J.; Schjønning, Per; Rasmussen, Karl J.
Optimisation of soil tilth is of paramount importance in organic plant production in order to enhance crop growth. Non-inversion and reduced tillage systems are often claimed to be preferable for organic farming. The purpose of this study was to evaluate the early stage effects of converting a mouldboard-ploughed soil to a non-inversion tillage system. A multi-level experimental strategy including in situ, on-site and laboratory methods was followed in order to relate quantitative measures of soil physical properties directly to soil behaviour in the field. A non-inversion deep soil loosening (0¯35 cm) tillage system (NINV) was compared to a conventional mouldboard ploughing and harrowing tillage system (CONV). The experimental site was located on an...

Organically grown grassclover in nature areas to remove soil phosphate for development of specious rich grasslands
Provedor de dados: 21
Autores: Timmermans, B.G.H.; Eekeren, N. van.
Worldwide the current reserves of phosphate rock are being exhausted. In The Netherlands many former agricultural soils have been enriched by large quantities of phosphorus as a result of fertilization. It is thought that this phosphorus prevents development of target-nature types. Nature organizations currently seek ways to remove it. We tested grassclover, organically managed by local farmers, as a tool to extract excessive soilphosphate from nature areas and reimport it into the mineral cycle agricultural farms. In a small scale experiment we have shown that grassclover with potassium fertilization can remove more than twice the amount of soil phosphate compared to mowing alone. We tested the methodology on 60 ha of grasslands in nature areas and...

Utvärdering av jordblandningar för ekologisk produktion av småplantor
Provedor de dados: 21
Plantuppdragning för utplantering i fält är en viktig metod för att förbättra grödornas konkurrenskraft mot ogräs och för att utnyttja odlingssäsongen optimalt. Ökade kunskaper om hur en jord ska vara sammansatt för att ge de bästa småplantorna är mycket angeläget för utvecklingen av ekologisk grönsaksodling. I dag finns inte heller kunskap om vilka halter av olika växtnäringsämnen i småplantorna som är optimala för den fortsatta utvecklingen i fält. Syftet med projektet är att studera hur olika jordblandningar inverkar på plantkvaliteten vid utplantering, etablering i fält, samt på den fortsatta utvecklingen fram till skörd. Växtnäringsinnehållet följs upp med analyser av jord och plantor.

Am Beispiel der Reduzierung von Bodenerosion konnte modellhaft gezeigt werden, dass die Integration von Umweltzielen für einen integrierten Betrieb mit geringeren Opportunitätskosten verbunden ist, als dies bei dem ökologisch wirtschaftenden Betrieb der Fall ist. Aufgrund der Notwendigkeit einer vielfältigen Fruchtfolge mit Zwischenfrüchten bzw. Untersaaten im ökologischen Landbau, ist das Erosionsrisiko im ökologisch wirtschaftenden Betrieb bereits ohne Auflagen deutlich niedriger, als die im integrierten Betrieb. Ein integrierter Betrieb ist in der Regel nur durch Zahlung von Prämien zu einer Berücksichtigung von Umweltzielen bereit.

The BIOMOD project has aimed at expanding, calibrating and validating two Danish dynamic simulation models, namely FASSET and Daisy, for a range of crop rotational situations occurring in organic farming. Here we report on the calibration results for an extensive experiment with residual effect and nitrate leaching following grass-clover leys.

Telen bij lage  fosfaatniveaus in de  biologische landbouw;  achtergronden en  literatuurstudie
Provedor de dados: 21
Autores: Timmermans, B.G.H.; Sukkel, Wijnand; Bokhorst, J.G.
Fosfor bevindt zich in anorganische en organische vorm in de bodem. Beide lijken van belang voor plantenvoeding, maar over de verhouding waarin deze bronnen een rol spelen voor akkerbouw op kalkhoudende klei en zavelgronden is nog onvoldoende bekend. De huidige bodemanalyses worden verbeterd, maar er wordt vooral anorganisch fosfaat geanalyseerd. Planten hebben veel mechanismen om fosfaat op te nemen, maar het speelt zich allemaal heel dicht bij de wortel af en de meeste potentieel beschikbare fosfaat is daarom toch niet effectief beschikbaar. De bodemstructuur en beworteling bepalen het deel van de bodem dat toegankelijk is. Verzorging van de bodemstructuur en stimulering van het bodemleven zijn belangrijke maatregelen om bij lage fosfaatniveau ’s te...

Microbially-mediated P fluxes in calcareous soils as a function of water-extractable phosphate
Provedor de dados: 21
Autores: Schneider, Kimberly D.; Voroney, R. Paul; Lynch, Derek H.; Oberson, Astrid; Frossard, Emmanuel; Bünemann, Else K.
Soil phosphorus (P) tests are designed to indicate plant-available inorganic orthophosphate (Pi), but fail to account for Pi that may become available through organic phosphorus (Po) mineralization. This P source may be especially important in soils with low concentrations of solution and labile Pi. We assessed gross Po mineralization and immobilization using labeling with 33P in four calcareous Alfisols with varying concentrations of Olsen soil test P that were collected from forage fields of dairy farms in Ontario, Canada. Rapid microbial 33P uptake during incubation was found for the soils with the lowest available Pi as indicated by both Olsen soil test P and water-extractable Pi. The tracer incorporation into microbial P after 8 days ranged from 7 to...

Engrais verts en interculture d’automne-hiver en plein champ - rapport final 2005
Provedor de dados: 21
Autores: Védie, Hélène; Taulet, Annick.
La lutte contre les adventices et l’amélioration de la fertilité sont deux priorités en agriculture biologique : la culture d’engrais verts est une méthode permettant de concilier ces 2 objectifs. Les engrais verts permettent notamment d’introduire une biodiversité « interculturale » dans les rotations, de maintenir ou d’améliorer les qualités agronomiques et structurales des sols et de réduire l’enherbement.     Les essais conduits par le GRAB en 2003 et 2004 ont permis de sélectionner plusieurs types d’engrais verts qui sont particulièrement performants sur ce créneau : les crucifères (moutarde, navette) et certains mélanges graminées et légumineuses. Ces engrais verts permettent de bien limiter le développement des adventices, une production de biomasse...

Soil Fertility and Biodiversity in Organic Farming
Provedor de dados: 21
Autores: Mäder, Paul; Fliessbach, Andreas; Dubois, David; Gunst, Lucie; Fried, Padrout; Niggli, Urs.
An understanding of agroecosystems is key to determining effective farming systems. Here we report results from a 21-year study of agronomic and ecological performance of biodynamic, bioorganic, and conventional farming systems in Central Europe. We found crop yields to be 20% lower in the organic systems, although input of fertilizer and energy was reduced by 34 to 53% and pesticide input by 97%. Enhanced soil fertility and higher biodiversity found in organic plots may render these systems less dependent on external inputs.

Organic greenhouses may cope with high loads of soil-borne pathogens: not only root knot nematodes, but also various kinds of plant-pathogenic fungi. In a field situation in an organic greenhouse, 3 treatments were tested for their effectiveness to suppress root-knot nematodes compared to control plots. The treatments consisted of (1) Sarepta mustard, (2) Sarepta mustard covered with a plastic sheet for 8 days, (3) Ricasa: a mixture of Ricinus communis, Capsicum annuum and formic acid. After the field treatments were carried out, soil was sampled and tested in a bioassay for suppressiveness against Fusarium oxysporum f.s. linii. The field treatments had a significant effect on soil suppressiveness against Fusarium. Soil of fields treated with Ricasa were...

Humusbilanzmethoden als Prognose- und Bewertungsinstrumente im ökologischen Landbau – allgemeiner und spezieller Anpassungsbedarf
Provedor de dados: 21
Autores: Brock, Christopher; Leithold, G.
Humus balances are intended to serve as instruments to support humus management in practice. Still, urgent need for adaptation especially with regard to apllication in organic farming has been stated.   Results presented in this paper show that there in fact is a difference in humus repro-duction between conventional and organic farming that is not recognized in balance methods. In addition, the results exhibit a big uncertainty in balance results. They are pointing out basic problems of humus balance methods that are likely to be caused by an insufficient consideration of site-specific factors of the humus household and their interaction with farming.

Autores: Coll, P; Le Cadre, E; Mérot, A; Villenave, C.
Soil nematofauna is a bioindicator that can highlight changes in biological functioning when changing agricultural practices. In the present study, the effects of conversion of vineyards to organic agriculture on biological soil quality were evaluated. Twenty four conventional plots and organic plots in Cruscades (Aude) were studied: they were divided into four groups: (1) conventional, (2) converted for 7 years (Bio 7 years), (3) converted for 11 years (Bio 11) and (4) converted for 17 (Bio 17). The nematofauna was analyzed in 96 soil samples (four samples per plot) taken from the surface layer of soil (0-15 cm). The more longer the conversion of plots to organic viticulture, the higher the biological activity of the soil; it is the abundance of non-plant...

Auf acht konventionell und acht ökologisch wirtschaftenden Ackerbaubetrieben im Marchfeld / Niederösterreich wurden im Frühjahr 2010 in allen festgestellten Habitattypen Regenwürmer erhoben. Es wurden v.a. endogäische Arten (Aporrectodea rosea, Aporrectodea caliginosa, Allolobophora chlorotica) gefunden. Weder das Bewirtschaftungssystem noch die Art der Bodenbearbeitung hatten einen Einfluss auf die Regenwurmabundanz. Anözische Regenwürmer wurden überwiegend auf naturnahen Habitaten gefunden. Ihre Abundanz könnte durch eine Erhöhung des Anteils dieser Habitattypen auf den Betrieben gefördert werden.

Biological soil quality as a factor of efficient resource utilization in organic farming systems
Provedor de dados: 21
Autores: Fliessbach, A.; Mäder, P.
In 1978 the DOK long-term field experiment was installed at Therwil close to Basel comparing the farming systems „bio-Dynamic“, „bio-Organic“ and „(K)conventional“. In the first years of the trial, crop yield and feasibility of organic farming were investigated. Soils were analysed with respect to long-term effects on fertility and were evaluated in the view of farming effects on the environment. Today the interrelation of diversity and efficiency and the quality of organic products is the research focus. Long-term trials like the DOK-trial offer unique opportunities for this kind of research.  The DOK-trial compares the three systems mentioned above on the basis of the same intensity of organic fertilization (i.e. the same number of animals per area), the...

Carbon sequestration in organic and conventional managed soils in the Netherlands
Provedor de dados: 21
Autores: Sukkel, Wijnand; van Geel, Willem; de Haan, Janjo.
Next to other important agronomic and ecological aspects, the organic matter sequestration in the soil plays an important role in the CO2 balance. Based on detailed farm registrations, the input of effective organic matter and the changes in carbon sequestration in the soil was calculated for a large number of organic and conventional farms in the Netherlands. Results show that both organic and conventional management resulted in a decrease of the pool of organic carbon in the soil. The average decrease for the conventional management was 401 kg ha-1 year-1 and for the organic management 261 kg ha-1 year-1. The input of effective organic matter in the soil was significantly higher in organic than in conventional farms. Animal manure was the main...

Farmers in coffee producing countries may not be aware of the economic, social and ecological benefits available through organic agriculture. At a local, regional and global scale, smallholder coffee farmers can discover that organic production methods are linked to provisioning, regulating, cultural and supporting ecosystem services. It is assumed that organic agriculture has a significant influence on soil parameters, and by association, on ecosystem services. Differences between farming systems in soil chemical properties reveal advantages for coffee farmers and shows the ecosystem services derived through organic agriculture at a local level.  Benefits discovered in organic coffee systems are higher inputs of organic matter, higher biodiversity of soil...

Erhöhte Bodenfruchtbarkeit durch reduzierte Bodenbearbeitung im Langzeitversuch Frick
Provedor de dados: 21
Autores: Mäder, Paul; Berner, Alfred; Niggli, Urs.
Weltweit ging in den vergangenen 40 Jahren etwa 1/3 des wertvollen Ackerlands durch Erosion verloren. Angesichts der Nahrungsmittelknappheit ist diese Entwicklung dramatisch, und es müssen neue Wege zur Lösung dieses Problems beschritten werden. Durch tiefes Pflügen wird wertvoller Humus abgebaut, der Boden erodiert, und das klimarelevante Gas CO2 wird freigesetzt. Pfluglose, konservierende Anbausysteme bieten Vorteile bei der Erosionsbekämpfung und bei der Förderung der Bodenfruchtbarkeit. Insbesondere können sie zum Humusaufbau beitragen und sparen Energie. Diese Anbausysteme wurden aber unter den Bedingungen des konventionellen Landbaus unter Einsatz von Herbiziden und Mineraldüngern entwickelt. Diese belasten die Umwelt und benötigen zu deren...

Autores: Hospers-Brands, A.J.T.M.; Pollema, Thomas; Bus, Michiel.
2014 was the third year of the "Planty Organic" system development in practice. The six-year rotation is laid out and measurements took place at soil and crop. The fertilizers used were completely produced in the own system, as foreseen in the system design. The nitrogen fixation by the grass clover, the motor of the system, did not meet the expected levels. The amounts of nitrogen applied were therefore about 20% lower than foreseen in the design. Soil nitrogen is measured and used as input in the nitrogen model NDICEA. There was a sufficient match between measured and calculated level of soil mineral nitrogen, with exception of the cereals where measured values of soil mineral nitrogen were consistently lower than the calculated levels. This showed also...

Omschakelen op slimme wijze: Geef een boost  met compost!
Provedor de dados: 21
Autores: Lauwers, Lore.
Kastelers die willen omschakelen naar biologische teelt streven ernaar hun bodem in een zo kort mogelijke tijdspanne klaar te krijgen voor een robuuste teelt. Zeker voor telers die een verkorting van de omschakelingsperiode kregen en die intensief vruchtgroenten willen gaan telen, is dit een hele uitdaging. De bodem die lang onder plastiek heeft gelegen heeft vaak een laag organische stofgehalte, weinig voedingselementen en weinig bodemleven. Een koolstoftoediening van 16 ton C/ha over de 2 jaar verspreid kan zorgen voor een gemiddelde toename van het totaal organisch koolstofgehalte in de bodem van 0.42%.

Hvad forstås ved begrebet jordens frugtbarhed
Provedor de dados: 21
Autores: Christensen, Bent T.
Jordens frugtbarhed afhænger af et komplekst samspil mellem naturgivne og menneskeskabte forhold. En karakterisering af jordens frugtbarhed kræver bestemmelse af flere nøgleparametres udvikling over tid. Begrebet jordens frugtbarhed kan meningsfyldt defineres som jordens evne til vedvarende at understøtte en landbrugsmæssig planteproduktion, der er forsvarlig med hensyn til omfang, kvalitet, rentabilitet og påvirkning af det omgivende miljø. Jordens frugtbarhed vil således være påvirket af driftsform og planteproduktionens teknologiske og økonomiske rammer.

Dutch (organic) agriculture, carbon sequestration and energy production
Provedor de dados: 21
Autores: van der Burgt, Ir. G.J.H.M.; Timmermans, Dr. B.G.H.; Staps, Ing. J.J.M.
Carbon sequestration in soils is often mentioned in the discussions about climate changes. In this paper the opportunities for carbon sequestration in Dutch agriculture are discussed at farm and national level. Farm internal carbon sources are already completely used in livestock farming. The effect under arable conditions is limited in time and very limited compared to national CO2 emission. External sources are scarce. Energy production out of crop residues and manure via biogas installations is possible but the overall impact is again very limited. The effect of this biogas pathway  on soil organic matter quantity and quality is not yet known. Organic arable farmers do already have a higher soil organic matter content than conventional farmers, partly...

A New Approach to Humus Balancing in Organic Farming
Provedor de dados: 21
Autores: Brock, Christopher; Hoyer, Uta; Leithold, Günther; Hülsbergen, Kurt-Jürgen.
Humus balances provide a profitable approach for humus dynamics assessment in farming practice. Nevertheless, there is a clear demand for methodological adaptation.     This article presents a new approach to humus balancing using reproducible algorithms for the estimation of balance coefficients. Humus balance coefficients for crops and organic fertilizers are estimated according to a bipartite algorithm. Humus demand  is calculated on the basis of crop yields referring to the nitrogen household in the plant-soil system. Humus supply is derived from organic matter input with plant material and fertilizers. The new approach facilitates the adaptation of the method to new situations.

Hoe kunnen veetelers met minder input meer resultaten halen bij snijmaïsteelt? Dat is de centrale vraag van het project “Duurzaam bodembeheer maïs” (BO-31.03-001-003). Veel melkveehouderijbedrijven telen snijmaïs, een gemakkelijk te telen ruwvoergewas met een goede productie van constante hoge kwaliteit. Als zetmeelbron met een ruime energie/eiwitverhouding past het goed in het runderdieet, naast gras en graskuil. De maïsteelt kan echter nadelige effecten hebben voor de bodem door gewasbeschermingsmiddelen en het uit- en afspoelen van nutriënten. Wageningen UR en het Louis Bolk Instituut onderzoeken in opdracht van het ministerie van EZ duurzame en praktisch haalbare verbeteringen en vernieuwingen.

The soil quality concept and its importance in the study of Finnish arable soils
Provedor de dados: 21
Autores: Palojärvi, Ansa; Nuutinen, Visa.
Arable soil is a functional unit whose condition is vital to crop production, but also to ecosystems at large owing to the significant role of soil in global nutrient cycles and balances. The soil quality concept recognises the concern for the sustainability of current arable land use practices. It integrates soil chemical, physical and biological properties, and takes account of the interaction of soil with water and air. This paper reviews the soil quality concept and its applications and discusses the importance of the concept for the assessment of Finnish arable soils. Many aspects of the chemical quality of arable soil are already well known in Finland. In contrast, follow-up of the physical and biological soil components, which are increasingly seen...

Langfristige Effekte einer Grünlanderneuerungsmaßnahme auf den Bodenkohlenstoffgehalt und die N2O-Emissionen
Provedor de dados: 21
Autores: Biegemann, Thorsten; Loges, Ralf; Taube, Friedhelm.
An increased demand for renewable raw materials for food and energy production has led to an increased intensification of agricultural production in northern Europe. Grassland, as well as arable production, has been affected by this development. Extensive grassland swards are often renovated with the aim of improving herbage yield and quality. The renovation of grassland leads to a reduction of CO2-C-fixation rates and increased soil mineralization processes. As a result levels of carbon losses and nitrous oxide (N2O) emissions increased in the short-term [1, 2]. Few studies have been carried out on the development of soil carbon and nitrous oxide emissions in medium or long-term (&gt;1 year). In order to identify carbon sequestration and N2O-emissions...

The aim of this study was to evaluate the interaction between yield levels of nonleguminous crops and soil organic matter (SOM) under the specific conditions of organic and conventional farming, respectively, and to identify implications for SOM management in arable farming considering the farming system (organic vs. conventional). For that purpose, correlations between yield levels of nonlegume crops and actual SOM level (Corg, Nt, Chwe, Nhwe) as well as SOM-level development were examined including primary data from selected treatments of seven long-term field experiments in Germany and Switzerland. Yield levels of nonlegume crops were positively correlated with SOM levels, but the correlation was significant only under conditions of organic farming, and...

Organic viticulture and soil quality: A long-term study in Southern France
Provedor de dados: 21
Autores: Coll, Patrice; Le Cadre, Edith; Blanchart, Eric; Hinsinger, Philippe; Villenave, Cécile.
The rate of conversion of conventional vineyards into organic farming is currently increasing. This results in modifications of agricultural practices such as the application of organic manure, the use of tillage or grass-cutting to control weeds and the application of natural pesticides with preventive action. One of the aims of organic farming is to preserve the environment. In this context, the objective of our work was to evaluate the long-term effects of organic viticulture on soil quality. The study was conducted in a commercial vineyard where plots which had been organically managed for 7 (Organic7), 11 (Organic11) and 17 years (Organic17) were compared to conventionally managed plots (Conventional).

LIVESTOCK IN ORGANIC FARMING – HOW IMPORTANT IS IT FOR SOIL FERTILITY MANAGEMENT?
Provedor de dados: 21
Autores: Schulz, Franz; Brock, Christopher; Leithold, Günter.
Stockless management is increasing even in organic farming, but it is not known until now, whether organic matter supply is sufficient in such systems, or which measures are necessary to achieve a sustainable soil organic matter (SOM) management. Results from the long-term Organic Arable Farming Experiment Gladbacherhof (OAFEG) show that after two 6 y rotations, only a “mixed farm” treatment (MF) with fodder legumes in the rotation and cattle manure application corresponding to 1 LU ha-1 was able to maintain, and in the long term perhaps increase, SOM levels. The “stockless farm” with fodder legumes as green manure ley (SFL) was barely able to maintain the SOM level, while the “stockless cash crop farm” where organic matter supply relied on green manure...

Autores: Gollner, Manfred; Friedel, Jürgen; Freyer, Bernhard.
The effect of continuous organic farming (OF) on the arbuscular mycorrhizal fungi (AMF) of winter wheat (Triticum aestivum) was investigated in a greenhouse pot trial. Representative soil samples were taken from 5 farms in the “Weinviertel” region, northeast of Vienna, Austria. On each farm three sites with a different duration of OF were selected for soil sampling; wheat was used as test plant. The mycorrhizal colonization (MC), root length density (RD) and the mycorrhizal colonized root length density (MD) were evaluated for the wheat roots. The majority of the wheat plants indicated an increasing MC and MD with increasing duration of OF. Based on our results we assume that a conversion period from conventional to OF of approximately 15 years is needed...

Autores: Lori, Martina; Symanczik, Sarah; Mäder, Paul; Efosa, Norah; Jaenicke, Sebastian; Buegger, Franz; Tresch, Simon; Goesmann, Alexander; Gattinger, Andreas.
The majority of soil organic nitrogen (N) is bound in protein-like compounds and therefore its proteolysis in peptides and amino acids is considered the initial and rate limiting step of N mineralization. Proteolysis of N bound in organic fertilizer and subsequent provisioning for crops is a central element in agro-ecological intensification. Long-term farming system effects on N provisioning from organic fertilizer to crops and its underlying functional microbial communities were analyzed in experiments conducted in soils from the “DOK” system comparison trial (bio-Dynamic, bio-Organic, and “Konventionell”) subjected to optimal and future projected drought scenarios.

The soil between the tracks remains undisturbed. Its structure is crumbly and thus optimal for plant growth.    Practical information  • Controlled traffic farming is a system approach that has an effect on the entire farm. Good preparation is necessary, e.g., by getting informed from colleagues who already use CTF.  • Depending on the farm and the available mechanization (esp. working width), there are several ways to work with tramlines. Examples are bed-cultivation with a 1.5 to 3.2 m track width or a default track-width (often 1.5 m) with standardized, often wide machines (3 to 9 m in width).  • Use standard equipment and standard working widths that are used on your own and on neighbouring operations (e.g. farmer-colleagues, agricultural contractors)...

Short-term effects of different techniques to prepare an organic citrus soil for replanting on its microbiological and biochemical properties
Provedor de dados: 21
Autores: Albiach, Remedios; Pérez-Piqueres, Ana; Domínguez, Alfons; Pomares, Fernando; Canet, Rodolfo.
Adopting measures to increment soil levels of organic matter and biological activity is key when an agrosystem is going to be converted to organic management. Nutrient reserves are increased and more easily mobilized, and soil suppresivity is enhanced. This last aspect is particularly relevant in replantations where chemical disinfection treatments can not be used and plantlets are very sensitive. A field trial is therefore being carried out to study the effects  on soil biochemical and microbiological properties  of different techniques(disinfectant vegetal cover, organic amendment and biofumigation, with untreated and solarized controls) to prepare the soil for replanting in a citrus orchard in convertion to organic management.

Structural vulnerability of a sandy loam exposed to intensive tillage and traffic in wet conditions
Provedor de dados: 21
Autores: Munkholm, L.J.; Schjønning, P.
Sustainable soil management requires that the structural degradation is balanced or exceeded by regeneration. Our objective was to investigate the vulnerability of topsoil structure to stress exerted by intensive tillage or traffic. The study addressed the short-term stability to disturbance as well as the recovery (resilience) within a year. A field experiment was conducted in a randomized block design on a humid sandy loam in 1997-1999. Each year, either compaction from a heavy tractor (PAC) or puddling by intensive rotary cultivation (PUD) produced a severe impact on topsoil structure. The PAC and PUD treatments were carried out on wet soil in early spring. The mechanical treatments were referenced by plots (REF), which were left undisturbed until the...

Soil fertility building measures should be explored at the short and long-term for an adequate evaluation of their impact on sustaining yields and of its environmental consequences in crop rotations under organic farming. For such a purpose, process-based crop models are potential useful tools to complement and upscale field observations under a range of soil and climatic conditions. Organic rotations differ in soil fertility dynamics in comparison to conventional farming but very few modelling studies have explicitly considered this specific situation. Here, we evaluate the FASSET model to predict the effects of different fertility management options in organic crop rotations on dry matter (DM) and nitrogen (N) yield, and soil N dynamics, including N2O...

Provedor de dados: 21
Autores: Cuijpers, W.J.M.; Smeding, F.; Amsing, J.; Postma, J.; Koopmans, C.J.
Four months after application of sheet steaming to the soil in an organic greenhouse, the treatment had still a significant effect on the diversity of the soil microflora (bacterial and fungal populations). Also four months after steaming, two fertilizer types differed significantly in their effect on microbial composition. Goat manure had a positive effect on bacterial diversity, while spent mushroom compost had a stimulating effect on fungal diversity.

Autores: Blumenstein, Benjamin; Knebl, Lucas; Gattinger, Andreas; Brock, Christopher; Wufka, André; Möller, Detlev.
Stroh ist ein essentieller Bestandteil der Kohlenstoffversorgung landwirtschaftlicher Böden. Humusersatzstrategien mit Strohnutzung können vielfältige Auswirkungen sowohl auf die Organische Bodensubstanz als auch die jeweilige Kostenstruktur aufzeigen, abhängig von Verwendungsform und Logistik. Die ökonomische Analyse verschiedener Strohnutzungsstrategien identifiziert das Belassen des Strohs auf dem Feld als kostengünstigste Alternative, die allerdings große Kohlenstoffverlustpotenziale aufweisen kann. Die (über-)betriebliche Nutzung von Stroh und dessen Rückführung in Wirtschaftsdünger, Kompost oder Gärresten (WKG) auf den Acker scheint vordergründig mit höheren Kosten verbunden zu sein, besonders bei Berücksichtigung steigender Transportentfernungen....

Soil phoD and phoX alkaline phosphatase gene diversity responds to multiple environmental factors
Provedor de dados: 21
Autores: Ragot, Sabine A.; Kertesz, Michael A.; Mészáros, Éva; Frossard, Emmanuel; Bünemann, Else K.
Alkaline phosphatases such as PhoD and PhoX are important in organic phosphorus cycling in soil. We identified the key organisms harboring the phoD and phoX genes in soil and explored the relationships between environmental factors and the phoD- and phoX-harboring community structures across three land uses located in arid to temperate climates on two continents using 454-sequencing. phoD was investigated using recently published primers, and new primers were designed to study phoX in soil. phoD was found in 1 archaeal, 13 bacterial and 2 fungal phyla, and phoX in 1 archaeal and 16 bacterial phyla. Dominant phoD-harboring phyla were Actinobacteria, Cyanobacteria, Deinococcus-Thermus, Firmicutes, Gemmatimonadetes, Planctomycetes and Proteobacteria, while...

Beneficial System Outcomes in Organic Fields at the Long-Term Agroecological Research (LTAR) Site, Greenfield, Iowa, USA
Provedor de dados: 21
Autores: Delate, Dr. Kathleen; Cambardella, Dr. Cindy; Chase, Dr. Craig; Turnbull, Robert.
In 1997, Iowa State University established the first U.S. Land Grant University permanent faculty position in organic agriculture to assist farmers in the rapid expansion of organic production in that state. Research agendas, developed in consultation with organic farmers and processors, led to the establishment of the Neely-Kinyon Long-Term Agroecological Research (LTAR) site in Greenfield, Iowa, in 1998 to study the long-term effects of organic production in terms of yield and economic performance, in addition to other system effects. Over nine years of comparison, there was no significant difference in corn or soybean yields in the organic and conventional systems. Organic corn yields in the longest rotation (C-S-O/A-A) over a 9–yr period were 9914...

An Innovative Approach towards Organic Management of Late Blight in Potato under Inhana Rational Farming Technology
Provedor de dados: 21
Autores: Bera, R; Seal, A; Chowdhury, R. Roy; Datta, A; Saha, S; Sengupta, K.
Successful disease combat of crop can ensure healthy return for the farmers. However, limitation in the conventional disease management approach, especially in case of late blight of potato was the background for the present study that aimed at bringing forth an alternative pathway for effective disease management. Integrated farming under Inhana rational farming technology (IRF) was adopted as an alternate protocol. The approach works on the philosophy of the Trophobiosis theory that advocates pest/disease management through plant physiology management. The study was done in two major potato growing zones of West Bengal taking two major potato varieties i.e., Kufri Jyoti and Kufri Chandramukhi. Late blight incidence varied from 2.82 to 7.91% in the IRF...

Species-specific root microbiota dynamics in response to plant-available phosphorus
Provedor de dados: 21
Autores: Bodenhausen, Natacha; Somerville, Vincent; Desirò, Alessandro; Walser, Jean-Claude; Borghi, Lorenzo; van der Heijden, Marcel G. A.; Schlaeppi, Klaus.
Phosphorus (P) is a limiting element for plant growth. Several root microbes, including arbuscular mycorrhizal fungi (AMF), have the capacity to improve plant nutrition and their abundance is known to depend on P fertility. However, how complex root-associated bacterial and fungal communities respond to changes in P availability remains ill-defined. We manipulated the availability of soil P in pots and compared the root microbiota of non-mycorrhizal Arabidopsis with mycorrhizal Petunia plants. Root bacteria and fungi were profiled using ribosomal operon gene fragment sequencing, we searched for P sensitive microbes and tested whether a P sensitive core microbiome could be identified. Root microbiota composition varied substantially by P availability. A P...

Effects of organic matter input on soil microbial properties and crop yields in conventional and organic cropping systems
Provedor de dados: 21
Autores: Chirinda, Mr Ngonidzashe; Olesen, Professor Jørgen, E.
Unlike conventional cropping systems, which are characterised by targeted short-term fertility management, organic farming systems depend on long-term increase in soil fertility and promotion of soil biodiversity. This study sought to investigate long-term effects of organic matter inputs on various cropping systems in a 10-year-old experiment. Results show that in the long-term high C and N inputs enhance microbial activity. Microbial biomass N and the potential nitrification rate were higher in cropping systems based on green manure than in those reliant on inputs from animal manure and mineral fertilizer. Soil microbiological properties were affected by the individual crops in the rotation. The high microbial activity with increased organic matter...

På store økologiske kvægbrug er der oftest meget græs i sædskiftet tæt på stalden for at begrænse køernes vej til malkning. Langvarige græsmarker er dog ofte mindre  produktive og af dårligere kvalitet. Men der er gode muligheder for græsmarker af længere varighed. Nye forskningsresultater har nemlig vist, at udbyttet i kløvergræs i mange tilfælde ikke var markant påvirket af markens alder, og pga. højt kløverindhold var effekten af gødning beskeden.

Vanwege de eindigheid van de wereldvoorraad makkelijk winbaar fossiel fosfor (P) en om fosforemissies uit (overbemeste) landbouwgronden naar grond- en oppervlaktewater te verminderen, is het Nederlandse landbouwbeleid gericht op het verlagen van fosforbemesting. Het wordt steeds belangrijker om het fosfor dat in de bodem aanwezig is, te benutten. Dit project heeft als doel te onderzoeken hoe dit kan en hoe dit gekwantificeerd kan worden. Er wordt ingegaan op de invloed van bemesting op de bodemfosfortoestand en de mogelijke rol van organisch fosfor in de fosforvoorziening van het gewas. Daarnaast wordt gekeken naar biologische bedrijven die telen met lage aanvoer van fosfor en lage bodemfosforstatus. Deze rapportage betreft de projectjaren 2012 en 2013.

Effect of management of topsoil structure
Provedor de dados: 21
Autores: Vignozzi, N.; Andrenelli, M.C.; L'Abate, G.; Pellegrini, S.
This paper aims to show the effectiveness of different soil management strategies for improving soil structure in degraded areas within two vine farms inTuscany(Italy). The management practices adopted were: Composted organic amendment addition (COMP), Green Manure (GM), Dry mulching (DM) and Control (CONTR). Topsoil samples were taken at the beginning of the trial (2015) and two years later, and analyzed for bulk density (BD) and aggregate stability by wet sieving. The strategies adopted to restore the functionality of degraded vineyard soils diversely affected BD and aggregates stability. In both the farms COMP proved to be the best strategy to reduce BD, while GM and DM gave the best results in terms of aggregate stability increase.

Improper or excessive land preparation methods in vineyards before planting can have a considerable impact on  soil functionality. They include excessive levelling and deep ploughing leading to disturbances of the natural contour  of slopes and destruction, truncation and burial of soil horizons. Manipulations may significantly modify  chemical, physical, biological and hydrological balance of soils. Problems that may arise from these interventions  relate to the reduction of organic substances, enrichment of calcium carbonate and soluble salts, impacting development  and health of grapevines. Reduced water retention capacity can lead to increased water stress during  dry season, decreased water permeability and circulation of oxygen in the soil, increased...

In this paper we present effects of four paired agricultural management practices (organic matter (OM) addition versus no organic matter input, no-tillage (NT) versus conventional tillage, crop rotation versus monoculture, and organic agriculture versus conventional agriculture) on five key soil quality indicators, i.e., soil organic matter (SOM) content, pH, aggregate stability, earthworms (numbers) and crop yield. We have considered organic matter addition, no-tillage, crop rotation and organic agriculture as “promising practices”; no organic matter input, conventional tillage, monoculture and conventional farming were taken as the respective references or “standard practice” (baseline).

SOIL QUALITY AND CROP PRODUCTIVITY AS AFFECTED BY DIFFERENT SOIL MANAGEMENT SYSTEMS IN ORGANIC AGRICULTURE "TILMAN-ORG Session"
Provedor de dados: 21
Autores: Willekens, Koen; Vandecasteele, Bart; De Vliegher, Alex.
A multi-year trial was conducted to compare soil management strategies (tillage and fertilization) with regard to their effect on crop performance and soil quality. Two soil management systems were assessed. Farm compost application was combined with reduced non-inversion tillage, whereas animal manure was incorporated by conventional tillage with a moldboard plough. With regard to soil quality, a reduced tillage practice in combination with compost application seemed to be favorable for soil quality of the surface layer in the short term. With regard to crop productivity, an effect of soil management strategy is less clear and dependent on a seasonal variation of growth circumstances.

Tensile strength of soil cores in relation to aggregate strength, soil fragmentation and pore characteristics
Provedor de dados: 21
Autores: Munkholm, Lars; Schjønning, Per; Kay, Bev D.
Tensile failure of soil is desirable in tillage. Soil tensile strength estimates most often are obtained from compression tests of dry aggregates. As tillage is performed under moist conditions, it would be highly relevant to measure tensile strength at high water contents.    Plough-layer soil was sampled in a compacted soil (PAC) and in a non-compacted reference soil (REF). Tensile strength was measured in a new direct tension test using undisturbed soil cores (4.45 cm in diameter and 5.00 cm in height) adjusted to either -50 or -100 hPa matric potential. The air-filled pore space, a, was determined from water retention measurements. Air permeability, Ka, was determined at -30, -100 and -300 hPa matric potentials and from these measurements an index of...

Visual soil assessment: field guide for cropping
Provedor de dados: 21
Autores: Shepherd, Graham.
Visual assessments provide an immediate diagnostic tool to evaluate soil quality, as many physical, biological (and to a lesser degree chemical) soil characteristics show up as visual characteristics. Results are easy to interpret and understand.   The Visual Soil Assessment (VSA) method has been developed to help land managers assess soil quality easily, quickly, reliably and cheaply on a paddock scale. It requires little equipment, training or technical skills.   Part I, “VSA of soil quality under cropping” uses a score card for soil indicators and for plant indicators. The different indicators and states of condition are shown in photos which enables a direct and qualitative on-field scoring and assessment.  Assessing and monitoring soil quality on your...

Ranking the magnitude of crop and farming system effects on soil microbial biomass and genetic structure of bacterial communities
Provedor de dados: 21
Autores: Hartmann, Martin; Fliessbach, Andreas; Oberholzer, Hans-Rudolf; Widmer, Franco.
Biological soil characteristics such as microbial biomass, community structures, activities, and functions may provide important information on environmental and anthropogenic influences on agricultural soils. Diagnostic tools and detailed statistical approaches need to be developed for a reliable evaluation of these parameters, in order to allow classification and quantification of the magnitude of such effects. The DOK long-term agricultural field experiment was initiated in 1978 in Switzerland for the evaluation of organic and conventional farming practices. It includes three representative Swiss farming systems with biodynamic, bio-organic and conventional fertilization and plant protection schemes along with minerally fertilized and unfertilized...

Arsenic and heavy metal concentrations in agricultural soils in South Savo province
Provedor de dados: 21
Autores: Mäntylahti, Väinö; Laakso, Pirkko.
Increasing concentrations of arsenic and heavy metals in agricultural soils are becoming a growing problem in industrialized countries. These harmful elements represent the basis of a range of problems in the food chain, and are a potential hazard for animal and human health. It is therefore important to gauge their absolute and relative concentrations in soils that are used for crop production. In this study the arsenic and heavy metal concentrations in 274 mineral soil samples and 38 organogenic soil samples taken from South Savo province in 2000 were determined using the aqua regia extraction technique. The soil samples were collected from 23 farms.The elements analyzed were arsenic, cadmium, chromium, copper, mercury, nickel, lead and zinc. The median...

Soil quality aspects of humid sandy loams as influenced by organic and conventional long-term management
Provedor de dados: 21
Autores: Schjønning, Per; Elmholt, Susanne; Munkholm, Lars J.; Debosz, Kasia.
The development of low-input farming systems requires knowledge of the extent to which management characteristics influence the soil as a habitat for micro-organisms and a medium for plant growth. This paper presents a study of long-term effects of organically and conventionally cultivated systems on a range of soil physical, chemical and biological characteristics in Denmark. Seven soils were included, falling into three groups (I¯III). Each group consists of an organically managed soil (Org) referenced by one or two conventionally managed soils (Conv) with the same soil type (sandy loam) and pedological history. All organically managed soils were dairy farm soils (H), which had been organically managed for 46, 47 and 40 years, respectively. They had...

Subsoil Compaction and Ways to Prevent It
Provedor de dados: 21
Autores: Van den Akker, J.J.H.; Schjønning, P.
Subsoil compaction affects all aspects of soil quality, and contrary to topsoil compaction it is persistent. Natural alleviation processes such as wetting/drying, freezing/thawing and biological activity including root growth decrease rapidly with depth. In compacted soil, these alleviation processes are moreover diminished because root growth and biological activity are reduced and soil water contents remain higher in compacted than in well-structured soil. Wheel loads are still increasing and, in consequence, the extent and severity of subsoil compaction. Sustainable soil management requires the uncompromising criterion that no subsoil compaction can be accepted. Consequently, only field traffic with wheel loads lower than the carrying capacity of the...

Økologisk landbruk og klimagasser - metan, lystgass og CO2
Provedor de dados: 21
Autores: Serikstad, Grete Lene.
Alle former for landbruk bidrar til utslipp av klimagasser, særlig av lystgass og metan. Måling av klimagassutslipp fra landbruket og lagring av karbon i jord er komplisert og er både tids- og stedsavhengig. Offisiell statistikk for landbruk omfatter ikke alle utslipp som hører med i landbruksproduksjonen, som utslipp ved produksjon av kunstgjødsel. Innhold av karbon i dyrkajord regnes heller ikke med. Kostholdsammensetning og matsvinn betyr dessuten mye for samlet utslippsmengde fra matproduksjon. Ved sammenligning av driftsformer er det viktig å ha med alle faktorer av betydning for klimapåvirkning.   De fleste vitensynteser og metaanalyser om klimagassutslipp fra ulike driftsformer konkluderer med at økologisk drift gir mindre utslipp per arealenhet...

A new approach to soil tillage for organic vegetable production: permanent beds
Provedor de dados: 21
Autores: Vedie, Hélène; Berry, Dominique; Leclerc, Blaise; Grébert, David; Lhôte, Jean-Michel.
The effect of controlled traffic with permanent crop beds was compared to mouldboard ploughing in France for organic vegetable production. Four trials were carried out over a period of three to seven years at four sites with different pedo-climatic conditions. Variable results were obtained, depending on soil type (susceptibility to compaction), tillage machinery type, vegetable type (root or not, grown from seed or transplant) and weed development. However, permanent crop beds with controlled traffic generally improved biological activity and reduced labour demand.

Berücksichtigung von Bodenvariabilität bei der Kalk-Ausbringung
Provedor de dados: 21
Autores: Kling, Charlotte.
In Brandenburg ist die räumliche Variabilität der kalkungsrelevanten Bodenparameter Textur, pH und Humus so groß, dass durch Beprobungen auf 3-5 ha Teilflächen gemäß den VDLUFA-Empfehlungen Unterschiede nur unzureichend erfasst werden. Dies bedingt bei pH-anspruchsvollen Kulturen, wie Luzerne und Kleearten, heterogene Bestände und einen geringeren Vorfruchtwert. Gerade im Ökolandbau ist es daher wichtig, kleinräumige pH bedingte Probleme zu erkennen und Methoden zu entwickeln, die ortsspezifisches Kalkmanagement ermöglichen.  Im Rahmen des EIP-Agri-Projektes „pH-BB: Präzise Kalkung in Brandenburg“ kommen zwei mobile Sensorplattformen auf einem ökologischen und zwei konventionellen Betrieben zum Einsatz.

Soil quality is defined as the capacity of the soil to perform multiple functions, and can be assessed by measuring soil chemical, physical and biological parameters. Among soil parameters, labile organic carbon is considered to have a primary role in many soil functions related to productivity and environmental resilience. Our study aimed at assessing the suitability of different labile carbon fractions, namely dissolved organic carbon (DOC), hydrophilic DOC (Hy-DOC), permanganate oxidizable carbon (POXC, also referred to as Active Carbon), hot water extractable carbon (HWEC) and particulate organic matter carbon (POMC) as soil quality indicators in agricultural systems. To do so, we tested their sensitivity to two agricultural management factors (tillage...

A long-term field experiment demonstrates the influence of tillage on the bacterial potential to produce soil structure-stabilizing agents such as exopolysaccharides and lipopolysaccharides
Provedor de dados: 21
Autores: Cania, Barbara; Vestergaard, Gisle; Krauss, Maike; Fliessbach, Andreas; Schloter, Michael; Schulz, Stefanie.
Background: Stable soil aggregates are essential for optimal crop growth and preventing soil erosion. However, tillage  is often used in agriculture to loosen the soil, which disrupts the integrity of these aggregates. Soil aggregation can be  enhanced by bacteria through their ability to produce exopolysaccharides and lipopolysaccharides. These compounds  stabilize soil aggregates by “gluing” soil particles together. However, it has yet to be shown how tillage influences the  bacterial potential to produce aggregate-stabilizing agents. Therefore, we sampled conventional and reduced tillage treatments at 0–10 cm, 10–20 cm and 20–50 cm from a long-term field trial in Frick, Switzerland. We compared the stable aggregate fraction of the soil and the bacterial...

Background  Agricultural production is challenged by the limitation of non-renewable resources. Alternative fertilizers are promoted but they often have a lower availability of key macronutrients, especially phosphorus (P). Biological inoculants, the so-called bio-effectors (BEs), may be combined with these fertilizers to improve the nutrient use efficiency.  Methods  The goal of this study was to assess the potential of three BEs in combination with alternative fertilizers (e.g., composted manure, biogas digestate, green compost) to promote plant growth and nutrient uptake in soils typical for various European regions. Pot experiments were conducted in Czech Republic, Denmark, Germany, Italy, and Switzerland where the same variety of maize was grown in...

Die wendende Bodenbearbeitung mit dem Pflug ist im biologischen und im konventionellen Ackerbau nach wie vor stark verbreitet. Im Biolandbau gilt der Pflug oft als Ersatz für die fehlenden Herbizide. Durch die wendende Bodenbearbeitung werden Ernterückstände und Samen in die Pflugtiefe von ca. 20 cm vergraben. Das hindert die Samen an der Keimung. Gepflügte Böden trocknen schneller ab. Das Zeitfenster für die Aussaat wird dadurch grösser. Auch der Start der Kulturen ist durch die schnell einsetzende Mineralisierung am besten.

In order to improve our understanding of soil aggregation, we have studied the relative importance of bonding and binding mechanisms, especially how they scale according to aggregate size and how they are influenced by farming system and different management options. Topsoil samples were collected from four arable sandy loam soils found as two pairs (FP1 and FP2) of neighbouring fields. One of the fields in FP2 had been grown for decades with annual cash crops without application of organic manures, while the other three fields had been managed with diversified crop rotations and manure dressings. Aggregates were segregated from the bulk soil by promoting brittle failure. The samples of soil structural units were fractionated to 4-8 mm, 0.5-1 mm and...

The influence of green manures as winter cover crops and these combined with composted cattle manure on soil properties, biodiversity indicators and crop yield was studied in a crop rotation experiment in three organic systems at the Estonian University of Life Sciences.  The use of green manures as winter cover crops and their combination with cattle manure brought tendencies to improve the soil quality: increased content of organic carbon, pH, soil water permeability, soil water holding capacity, soil microbial activity and abundance of earthworms and ground dwelling arthropods. Depending on the year, yield level of all main crops was increased due to improved soil properties caused by green manures.

The Muencheberg Soil Quality Rating (SQR)
Provedor de dados: 21
Autores: Mueller, Lothar; Schindler, Uwe; Behrendt, Axel; Eulenstein, Frank; Dannowski, Ralf.
The Muencheberg Soil Quality Rating (M-SQR) is a simple and fast semi-quantitative method, which can be used by farmers and advisors. This field scoring method is used to analyse soil properties that limit crop yields and crop productivity potentials. Potential applications of the method are soil resource planning, guiding land purchase, and assessment of sustainability and environmental impacts of land use.   Ratings of soil quality are made during common soil survey mainly by applying visual methods of soil quality. Only a minimum of equipment is required for the field assessment. A field manual provides rating tables based on response curves and thresholds for basic indicators and different hazard indicators (such as risk of drought).   Finally, overall...

1. Organic farming (OF) enhances top soil organic carbon (SOC) stocks in croplands compared with conventional farming (CF), which can contribute to sequester C. As farming system differences in the amount of C inputs to soil (e.g. fertilization and crop residues) are not enough to explain such increase, shifts in crop residue traits important for soil C losses such as litter decomposition may also play a role.    2. To assess whether crop residue (leaf and root) traits determined SOC sequestration responses to OF, we coupled a global meta-analysis with field measurements across a European-wide network of sites. In the meta-analysis, we related crop species averages of leaf N, leaf-dry matter content, fine-root C and N, with SOC stocks and sequestration...

Eine kritische Analyse von Ruschs Theorien zur Bodenfruchtbarkeit als Grundlage für die Bodenbewirtschaftung im Ökologischen Landbau
Provedor de dados: 21
Autores: Paulsen, Hans Marten; Schrader, Stefan; Schnug, Ewald.
Auf die in den 50er und 60er Jahren publizierten Theorien zur Bodenfruchtbarkeit von Hans Peter Rusch wird im organisch-biologischen Landbau heute noch Bezug genommen. Zu nennen sind hier der Rusch-Test zur Einstufung der biologischen Qualität der organischen Substanz und von Böden, die Systematisierung des Abbaus organischer Substanz im Boden und der Humusbildung sowie die Flächenkompostierung. Ruschs Lehren zielen auf eine Verbesserung der Bodengare durch effiziente Zufuhr organischer Substanz und Humusbildung sowie auf die Verbesserung der Ausnutzung von Nährstoffen. Gegen den Geist seiner Zeit grenzte sich Rusch von der Mineraldüngung ab und hebt die auch heute unbestrittene Rolle des Humus für die Bodenfruchtbarkeit hervor. Die tatsächliche Bedeutung...

Solid-state 13C NMR characterization of surface fire effects on the composition of organic matter in both soil and soil solution from a coniferous forest
Provedor de dados: 21
Autores: Näthe, Kerstin; Delphis, F. Levia; Steffens, Markus; Michalzik, Beate.
Wildfires change the chemical composition of soil organic matter (SOM). Since the effects of fires on organic matter (OM) in soil solution are largely unknown, we sought to compare the quality of dissolved organic matter (DOM) and total organic matter (TOM =DOM +particulate OM) between burned and control sites. The sites were subjected to a low-intensity surface fire in a coniferous forest in Germany dominated by spodic Cambisols derived from Triassic sandstone. Soil solutions from three different soil horizons (O, Ah, Bw), and throughfall (TF) were analyzed using solid state 13C NMR spectroscopy, allowing us to track the initial fire impact on OM vertically through the soil profile and 70 days after the fire. In addition, organic layer samples were...

The role of soil science in optimization of soil resource management
Provedor de dados: 21
Autores: Schjønning, P.
Soils in the Nordic countries are threatened, primarily by erosion, compaction, and loss of OM. The EU Soil Thematic Strategy has suggested a Framework for implementation of tools to counteract the threats to a sustained soil quality. Soil scientists should take part in this process and accept the need to do so in a close cooperation with stakeholders and fellow col-leagues in related scientific branches. The diversity of soils calls for the development of GIS-based tools to identify the best strategy at given locations. An isolated focus on soil quality indicators in monitoring programmes is strongly discouraged.

Controlled traffic farming increased crop yield, root growth, and nitrogen supply at two organic vegetable farms
Provedor de dados: 21
Autores: Hefner, M.; Labouriau, R.; Nørremark, Michael; Kristensen, Hanne Lakkenborg.
Increased farm machinery weight in agricultural production results in soil compaction. Controlled traffic farming (CTF) restricts traffic to permanent lanes, thereby creating traffic free beds for crop production. Field experiments were conducted at two organic vegetable farms in Denmark, on a sandy loam (2013–2016) and on coarse sand (2013–2015) to investigate CTF effects compared with random traffic farming (RTF) on vegetable yield, root growth, and soil mineral nitrogen (N). Root growth was measured using minirhizotrons. White cabbage, potato, and beetroot yield increased by 27%, 70% and 42%, respectively, in CTF compared with RTF in 2015 and winter squash indicated a yield increase of 43% on sandy loam in 2016. White cabbage (2015) and potato, beetroot...

Small‐scale distribution of copper in a Technosol horizon  studied by nano‐scale secondary ion mass spectrometry
Provedor de dados: 21
Autores: Rennert, Thilo; Höschen, Carmen; Rogge, Derek; Steffens, Markus.
Rationale: In contaminated soil, copper (Cu) is commonly distributed among various very small particles. To enlighten the qualitative distribution of Cu in a contaminated Technosol (a soil developed from deposited technogenic material) on the sub‐micron scale, we used nano‐scale secondary ion mass spectrometry (NanoSIMS).  Methods: We studied seven areas (up to 40 μm × 40 μm) on a thin section of a soil horizon by NanoSIMS, measuring 12C−, 18O−, 32S−, 63Cu− and 56Fe16O−. We evaluated the NanoSIMS measurements with a novel digital image processing tool to enlighten the composition of measured areas and thus the distribution of Cu at the sub‐micron scale. Image processing comprised spatial and spectral smoothing, normalization, endmember extraction and...

Autores: Leong, KI; Lohr, D.; von Tucher, Sabine; Meinken, E.
P-recycling from biogas residue may play a future key role for sustainable P supply in organic farming. However, in particular transportation costs of residue need to be  reduced e.g. by pretreatment. One approach is carbonization by pyrolysis or hydrothermal carbonization (HTC). In a pot trial with maize on a P-deficient, acidic sandy loam P uptake after application of two chars from pyrolysis (400 and 700 °C) and HTC (6 and 8 h dwell time) all made of the same residue was compared to P uptake after application of the raw residue and water soluble KH2PO4 respectively. P  uptake was the same for KH2PO4, raw residue and both HTC treatments, but was significant lower in treatments with pyrolytic chars. Neither dwell time nor temperature  had an effect....

Effekten af økologiske driftsmetoder på ler-dispergering i kulstof-udpinte jorde
Provedor de dados: 21
Autores: Schjønning, P.; de Jonge, L.W.; Olesen, J.E.; Greve, M.H.
Mange danske jorde – især på Øerne – har i dag et lavt indhold af organisk stof som følge af årtiers ensidige kornsædskifter og ringe brug af husdyrgødning. I denne artikel viser vi, at lerpartikler (kolloider) i jord med et lavt indhold af organisk stof frigøres til jordens vandfase (dispergering), hvilket efterfølgende kan have store påvirkninger af vigtige jordfunktioner. Økologiske driftsformer er generelt karakteriseret ved en stor tilbageførsel af organisk stof til jorden og kan derfor potentielt modvirke den omtalte lerdispergering.

Autores: Blumenstein, Benjamin; Brock, Christopher; Dannehl, Theresa; Möller, Detlev.
Management measures to maintain or increase soil organic matter (SOM) are generally associated with additional costs and a decreasing profitability of crop rotations. However, certain SOM-enhancing strategies may have the potential to  synergistically optimize also the economic output in the short or long term. We evaluated several crop rotations and green/straw manuring systems on diverging site properties in stockless farm systems for their effects on production economics. Benefits may especially derive from an increased spatio-temporal synchronization of crop nutrient demand and nutrient supply by turning green manures into mobile  fertilizers, which can even result in short term economic benefits. However, as effects do not necessarily show instantly,...

Lower P-input levels in organic than conventional farming can decrease soil total and available P, which can potentially be resupplied from soil organic P. We studied the effect of 30 y of conventional and organic farming on soil P forms, focussing especially on organic P. Soil samples (0–20 cm) were taken in a field experiment with a nonfertilized control, two organic systems receiving P inputs as animal manure, and two conventional systems receiving only mineral P or mineral P and manure. Soils were analyzed for total, inorganic, organic, and microbial P, by sequential P fractionation and by enzyme additions to alkaline soil extracts. Samples taken prior to starting the experiment were also analyzed. Average annual P balances ranged from –20 to +5 kg...

Autores: Fließbach, Andreas; Krauss, Maike; Maurer, C.; Dierauer, Hansueli; Mäder, Paul.
When residues and organic fertilizers are not incorporated into the soil, they build a top soil layer that is enriched in soil organic matter. This is leading to a soil layer with  increased biological activity, while the soil layers below, receive less inputs in form of residues or manures and show a reduction in soil organic matter and biological activity. Soils from a replicated field trial and two on-farm trials were analysed for biological soil quality 6 years after the implementation of reduced tillage (RT) as compared to plough. Whilst crop yields were slightly lower with RT, weed cover was increasing, but not to a level that would compromise yields. Soils under RT accumulated soil organic matter in the tilled top layer of 0-10 cm, while in the...

Effects of organic matter input on soil microbial properties and crop yields in conventional and organic cropping systems
Provedor de dados: 21
Autores: Chirinda, Mr Ngonidzashe; Olesen, Professor Jørgen, E.; Porter, Professor John, R.
Unlike conventional cropping systems, which are characterised by targeted short-term fertility management, organic farming systems depend on long-term increase in soil fertility and promotion of soil biodiversity. This study sought to investigate long-term effects of organic matter inputs on various cropping systems in a 10-year-old experiment. Results show that in the long-term high C and N inputs enhance microbial activity. Microbial biomass N and the potential nitrification rate were higher in cropping systems based on green manure than in those reliant on inputs from animal manure and mineral fertilizer. Soil microbiological properties were affected by the individual crops in the rotation. The high microbial activity with increased organic matter...

Auswirkungen des langfristigen ökologischen Landbaus auf bodenbürtige Treibhausgasemissionen
Provedor de dados: 21
Autores: Gattinger, Andreas; Skinner, Colin; Krauss, Maike; Mäder, Paul.
Despite the increase in organic cropland, knowledge on the impact of organic farming on soil-derived nitrous oxide (N2O) and methane (CH4) emissions is rather limited. To improve the knowledge base, N2O and CH4 fluxes were investigated in a 571 day lasting cropping sequence in the “DOK” field trial. Two organic and two non-organic farming systems and an unfertilized control were chosen. For the whole monitoring, the two organic systems combined emitted 40% less N2O than the two non-organic ones cumulated on area-scale. Yield-scaled cumulated N2O emissions were nearly 10% lower for the organic systems combined, despite the yield gap of 27%. We found that besides N input, management induced soil quality properties drive differences in N2O emissions between...

Die angewendeten Methoden erwiesen sich als geeignet, um die mikrobiellen Gemeinschaften und deren physiologische Eigenschaften in den Böden der Anbausysteme des DOK-Versuches zu untersuchen. Sämtliche Parameter konnten Veränderungen der physiologischen Eigenschaften und taxonomischen Zusammensetzung beschreiben, die hauptsächlich auf die unterschiedlichen  Anbausysteme und Kulturen zurückzuführen sind. Es stellte sich zudem heraus, dass die Veränderungen besonders durch die Art der Düngung (organisch vs. mineralisch) hervorgerufen wurden. Die Untersuchung hat gezeigt, dass eine verknüpfende Betrachtung der Ergebnisse der hier angeführten Analysemethoden sinnvoll ist, um zukünftig verbesserte Aussagen über Bodenqualität und -fruchtbarkeit in...

Standardisierung eines Kressetestes für das  biologischdynamische Hornmistpräparat
Provedor de dados: 21
Autores: Morau, A.; Fritz, Jürgen.
The biodynamic preparations have been investigated mainly in field trials. By contrast long-term project is to establish a rapid bioassay to evaluate the effectiveness of the  horn manure preparation (HMP). The investigated bioassay is based on hydroponically grown cress (Lepidium sativum L.) as an indicator plant. Past results indicated its sensitivity for typical dilutions of HMP in agricultural practice. However one limiting point was the use of non-standard local well water as hydroponic solution. The aim of the present study was to standardise this parameter. A series of 8  experiments was conducted to compare a selected mineral water with well water. The results indicate a highly significant (p&lt;0,001) effect of the HMP on the root´s length  was...

Turnover of organic matter in differently textured soils. I. Physical characteristics of structurally disturbed and intact soils
Provedor de dados: 21
Autores: Schjønning, P.; Thomsen, I.K.; Møberg, J.P.; de Jonge, H.; Kristensen, K.; B.T., Christensen.
Soil type effects on organic matter turnover are most often ascribed directly to differences in soil clay content. Since soil texture determines the physical characteristics of soil, aggregation and water holding capacity may be more relevant to address in the search for controls of organic matter turnover. Most studies of microbial processes in soils are based on structurally disturbed soil, where the abiotic conditions for the microbial activity may be quite different from those in intact soils. In this study, basic physical characteristics were determined for structurally disturbed and intact soil samples from differently textured soils. Bulk soil was retrieved from 0–20 cm depth at six locations along a textural gradient in an arable field on...

Autores: Krauss, Maike; Berner, Alfred; Fliessbach, Andreas; Pfiffner, Lukas; Mäder, Paul.
Im Ackerbau sitzt man in Sachen Bodenbearbeitung zwischen zwei Stühlen. Zum einen bringt eine intensive Bodenbearbeitung zumindest kurzfristig oft agronomische Vorteile, zum anderen birgt sie ein hohes Erosionsrisiko und beeinträchtigt das Bodenleben stark. Es gilt, einen Mittelweg zu finden, der eine nachhaltige und bodenschonende Bewirtschaftung ermöglicht, ohne die momentane landwirtschaftliche Produktivität zu reduzieren.

Autores: Schjønning, Per; Lamandé, M.
Titlen kan lyde som en vittighed: jorden skal bære trafikken,- den skal være bæredygtig. Men driftsmetoder, der skader jorden vedvarende er ikke bæredygtige. Og nutidens maskiner giver skader. Man kunne også stille spørgsmålet, om man kan tale om ”økologisk trafik”? Økologerne har været foregangsmænd/-kvinder hvad angår udfasning af pesticider og mineralsk gødning. Budskabet i denne artikel er, at der ligger en tilsvarende udfordring og venter mht vores trafik i marken.

Regenerative Landwirtschaft – Bewertung des Systems durch die Erweiterte Spatendiagnose am Beispiel Kartoffel
Provedor de dados: 21
Autores: Junge, Stephan Martin; Pfister, Janna; Wedemeyer, Rainer; Finckh, Maria Renate.
Der Kartoffelanbau ist ein wichtiges ökonomisches Standbein vieler Biobetriebe. Die intensive Bodenbearbeitung gefährdet die Bodenstruktur und erhöht das Risiko von Wasser- und Winderosion. Die regenerative Landwirtschaft hat den Anspruch, den Boden während des Anbaus zu verbessern, was in der Praxis erprobt und diskutiert wird. In einem einjährigen Experiment wurden Techniken der regenerativen Landwirtschaft auf den Kartoffelanbau angewandt und durch die erweiterte Spatendiagnose bewertet. Erste Ergebnisse zeigen, dass eine reduzierte Bodenbearbeitung mit und ohne Mulch die Bodenstruktur verbessert unter Beibehaltung wirtschaftlicher Erträge.

Autores: Finckh, Maria R.; Bacanovic, Jelena; Junge, Stephan; Wedemeyer, Rainer; Schmidt, Jan Henrik; Hallmann, Johannes; Baresel, Jörg Peter.
In diesem Artikel konnte nur ein sehr kleiner Einblick in das Projekt OSCAR gegeben werden. Inspirationen kommen vor allem aus Südamerika, wo die Direktsaat bereits Standard ist. Die erfolgversprechendsten Arten als Zwischenfrüchte und Untersaaten werden von mehreren Projektpartnern gemeinsam mit beteiligten Landwirten in der Praxis getestet. OSCAR wird jedoch zum Projektende noch keine fertigen Lösungen bieten können.  Mit dem sich deutlich wandelnden Klima auch in Deutschland werden Boden- und Wasserschutz immer wichtiger. Dazu tragen die Lösungsansätze von OSCAR bei. Es sind aber bereits einige Folgeprojekte entstanden.  Dazu gehört vor allem ein Projekt zur Züchtung von Untersaaten unter den Bedingungen der Minimalbodenbearbeitung.

Earthworm species and burrows related to agricultural management of clover-grass rotations
Provedor de dados: 21
Autores: Krogh, P.H.; Lamandé, M.; Eriksen, J.; Holmstrup, M.
Clover grass is an important element in crop rotations due to its beneficial agronomic properties including nitrogen build-up, biodiversity stimulation and maintenance of soil macropores and it harvests very high levels of earthworm biomass. We studied the relationship between crucial ele-ments of a clover grass crop rotation and earthworm diversity and macropore depth distribution. The dominance of anecics increased from the annual crops to the perenial clover-grass. Aporrec-todea tuberculata decreased significantly Cattle grazing seems to favour coarse macropores made by anecics, Aporrectodea longa and Lumbricus terrestris. Our study stresses the importance of considering subsoil macropores to complete the picture of earthworm influence on soil...

This report describes a new method for composting and its use for cultivation of plants in greenhouse. The composting is performed in a combined stable and greenhouse directly in the mixture of cow manure and wood chips under the cows – a compost barn. This method is known for example in USA, Israel and Netherlands. In Norway a newly constructed compost barn with 18 sucklercows was followed by four visits and tests during 2017 and 2018. The animal welfare was no issue. The focus was on compost quality for growth media and the plant growth performance. During summertime, when cattle was outdoor, tomatoes, peppers and squash were cultivated. Compost was analysed in the beginning and the end of season. Compost maturity was evaluated by different standards and...

Short-term effects of tillage on mineralization of nitrogen and carbon in soil
Provedor de dados: 21
Autores: Kristensen, Hanne L.; Debosz, Kasia; McCarty, Greg W.
Tillage is known to decrease soil organic nitrogen (N) and carbon (C) pools with negative consequences for soil quality. This decrease is thought partly to be caused by exposure of protected organic matter to microbial degradation by the disturbance of soil structure. Little is known, however, about the short-term effects of tillage on mineralization of N and C, and microbial activity. We studied the short-term effects of two types of tillage (conventional plough- and a non-inverting-tillage) on mineralization and microbial N and C pools in a sandy loam under organic plough-tillage management. The release of active and protected (inactive) N by tillage was further studied in the laboratory by use of 15N labelling of the active pool of soil N followed by...

Autores: Kauer, Karin; Tein, Berit; Sanches De Cima, Diego; Talgre, Liina; Eremeev, Viacheslav; Loit, Evelin; Luik, Anne.
Maintaining or enhancing the stock of soil organic carbon (SOC) is a key factor in sustaining the soil resources of the world. The objective of this research was to study the effect of different farming systems (conventional farming with mineral fertilizers and crop specific fertilization vs. organic farming with organic fertilizers (catch crops and composted manure)) under the same 5-crop rotation (red clover, winter wheat, pea, potato, barley undersown with red clover) system on the SOC stock and the stability of SOC. The second aim was to quantify plant C inputs to the soil and to identify the relationship between C sequestration rate and C input. Data presented in this paper concerned the first rotation during 2008–2012. The main factors were farming...

The Impact of Organic Cotton Farming on the Livelihoods of Smallholders. Evidence from the Maikaal bioRe poject in central India
Provedor de dados: 21
Autores: Eyhorn, Frank; Mäder, Paul; Ramakrishnan, Mahesh.
This research report analyses the impact of conversion to organic cotton farming on the livelihoods of smallholders in the Maikaal bioRe organic cotton project in Madhya Pradesh, central India. For that purpose, it compares farm profile data, material and financial input/output and soil parameters of organic and conventional farms over two cropping periods (2003 – 2005). The results show that organic farms achieve cotton yields that are on a par with those in conventional farms, though nutrient inputs are considerably lower. With less production costs and a 20% organic price premium, gross margins from cotton are thus substantially higher than in the conventional system. Even if the crops grown in rotation with cotton are sold without organic price...

Management &amp; sustainability of stockless organic arable and horticultural systems
Provedor de dados: 21
Autores: Preston, Keith.
This review draws on the research into stockless systems and addresses the challenges of conversion planning, rotation design, maintaining soil nutrient status, weed control, pest control and economic return.     Traditional organic systems of mixed farming with alternate husbandry rely on fertility building leys and livestock manures to provide break crops and fertility building. However, the trend within agriculture has been a move away from mixed farming systems to specialist units. Stockless organic farming involves the use of green manures and green waste compost to replace livestock and animal manures.    The infrastructure costs (fencing, water and buildings) of introducing livestock into an all arable farm are often prohibitively expensive and...

Nutrient supply to organic agriculture as governed by EU regulations and standards in six European countries
Provedor de dados: 21
Autores: Loes, A-K.; Bünemann, E.; Cooper, J.; Hörtenhuber, S.; Magid, J.; Oberson, A.; Möller, K.
Organic farming systems need to replace nutrients exported via farm products, especially phosphorus (P) which may otherwise become depleted in soil in the long term. In Europe, EU regulations for organic production are shaping the farming systems with respect to inputs of nutrients. Permitted off-farm P sources include conventional animal manure, composted or anaerobically digested organic residues, rock phosphate, and some animal residues such as meat and bone meal. The recent proposed revision of EU regulations for organic production (2014) puts less emphasis on closing nutrient cycles and instead aims at minimizing off-farm inputs, to reduce the risk of importing contaminants. This development, which has received little attention from the organic sector...

Effects of High Stocking Grazing Density of Diverse Swards on Forage Production, Animal Performance and Soil Organic Matter: A Case Study
Provedor de dados: 21
Autores: Zaralis, Konstantinos; Padel, Susanne.
Mob grazing is regarded as a grazing management practice to increase soil organic matter, pasture productivity and nutrient cycling. There are different perspectives in the literature regarding the definition of mob grazing, but it is generally accepted that mob grazing is characterised by high stocking densities of livestock which are moved frequently from paddock to paddock (e.g.  with the aid of electric fences), trampling forage into the soil as they graze. It has also been recognised that biodiverse pastures have the potential to build up carbon levels in the soil much more effectively than conventional (usually monocultures) or less diverse pastures; in turn all can enhance animal productivity and maintain good herd health.   This paper reviews the...

Soil organic matter and soil quality - lessons learned from long-term experiments at Askov and Rothamsted
Provedor de dados: 21
Autores: Christensen, B.T.; Johnston, A.E.
The various elements of an arable cropping system, such as crop type and cultivar, soil tillage, crop protection measures, use of mineral fertilizers and animal manure, crop-residue disposal, and addition of town-derived organic refuses all interact in a complex manner with basic soil properties (texture and mineralogy), and this interaction determines the general productivity of the cropping system. The same elements also influence soil organic matter (SOM) turnover, some more than others. The SOM holds large pools of organically bound plant nutrients, which, through mineralization, may become available for crop uptake or loss from the soil-plant system through leaching or gaseous losses. Additionally, SOM is important to both soil structure and the...

A comparison of soil properties under organic and conventional farming in Australia
Provedor de dados: 21
Autores: Nachimuthu, Gunasekhar; Kristiansen, Paul; Lockwood, Peter; Guppy, Chris.
Organic farming is an alternative to conventional farming for providing sustainable crops with high export demand. This review analyses research findings on organic farming in Australia, with an emphasis on soil health. Several reports have indicated that organic farm management generally improves soil physical properties in Australia and elsewhere. Although low nitrogen (N) availability can constrain yields, organic farmers can improve N supply through legume green manures. Plant available phosphorus (P) is a more serious limiting factor in organic farming, particularly in Australia with naturally low P levels. Phosphorus is less easily replaced in the soil than N, and there is a need for alternate sources of organic-certified P and methods to enhance P...

Er kamme et alternativ til pløjning?
Provedor de dados: 21
Autores: Bugge Henriksen, Christian.
På Landbohøskolen arbejder vi med et alternativt jordbearbejdningssystem, hvor man i stedet for at pløje hypper jorden op i kamme om efteråret. Opsætning af kamme hvor det øverste jordlag lægges ind i kammen er en langt mere skånsom jordbehandling end pløjning hvor jorden vendes rundt. I forhold til andre former for pløjefri dyrkning har kamme den umiddelbare fordel, at de giver bedre mulighed for at indarbejde husdyrgødning og afgrøderester i jorden, ligesom de giver bedre mulighed for at bekæmpe ukrudtet mekanisk. Vores foreløbige resultater viser desuden at kamme rummer muligheder for at reducere udvaskningen af kvælstof og øge omsætningen af organisk stof.  I det nystartede projekt (CARMINA) undersøger vi mulighederne for at få dyrknings-systemer med...

Effect of vetch wheat mixture and broccoli as preceding crops on organic summer vegetables: on farm trial in western Turkey
Provedor de dados: 21
Autores: ASLAN, Burcay.
Organic farming requires the use of practices such as crop rotation, green manure and compost application instead of chemical compounds to enhance farm productivity. In this study, effects of two pre-crops (vetch-wheat mixture and broccoli) and additional fertilization (AF) strategy (compost and commercial fertilizer) were tested on organic production of two main crops (tomato and zucchini) and on soil fertility. The main aim of this on-farm trial is to evaluate the applicability of the results obtained over four years study under experimental conditions. Pre-crops and AF strategy had no significant effect on zucchini yield; highest tomato yield was recorded after vetch-wheat mixture and AF. At the end of the cycle soil organic matter statistically...

Monetäre Auswirkungen angepassten Reifeninnendrucks im Ackerbau unter besonderer Berücksichtigung der Erbsen
Provedor de dados: 21
Autores: Wolf, Daniel; Möller, Detlev; Schmidt, Harald; Wild, Melanie; Demmel, Markus.
A goal in ecological agriculture is to avoid and reduce soil compaction. One possibility is the use of a tire inflation system (TIS). Additionally, sowing equipment with broader working width can be used. Both technologies save working time and fuel. Furthermore, yield could increase due to less soil compaction, especially for peas as field trials show. Data from the field trials and from original farms were used to calculate the profitability for the soil protection technologies. The fuel savings are enough to cover the variable and fix costs of the TIS. The pea surplus is an extra revenue. If working time reduction is additionally valued than in total the farms can gain above 19,-€/ha arable land using a TIS. The most farms have not enough traction power...

Threats to soil quality in Denmark - A review of existing knowledge in the context of the EU Soil Thematic Strategy
Provedor de dados: 21
Autores: Schjønning, P.; Heckrath, G.; Christensen, B.T.
The EU Commission is preparing a proposal for a Soil Framework Directive with the purpose of protecting the soil resources in Europe. The proposal identifies six major threats to the sustained quality of soils in Europe. This report addresses the threats that are considered most important under the prevailing soil and climatic conditions in Denmark: compaction, soil organic matter decline, and erosion by water and tillage. For each of these threats, the relevance and damage to soil functions as well as the geographic distribution in Denmark are outlined. We suggest a procedure for identifying areas at risk. This exercise involves an explicit identification of: i) the disturbing agent (climate / management) exerting the pressures on soil, and ii) the...

Driftsformen har begrænset effekt på jordens evne til at holde på vandet
Provedor de dados: 21
Autores: Schjønning, P.; Iversen, B.V.; Jacobsen, O.H.
Mængden af organisk stof, som man påvirker med almindelig landbrugsdrift, har ikke nævneværdig indflydelse på jordens vandholdende evne.  Anvendelse af husdyrgødning i stedet for mineralsk gødning kan heller ikke forventes at påvirke jordens ledningsevne for vand i pløjelaget.   I forhold til ekstreme driftsformer med et ensidigt (korn-)sædskifte og uden anvendelse af organisk gødning vil en økologisk driftsform give både et større porevolumen og et mere forgrenet poresystem.   Et højt næringsstofniveau giver – uanset tildelingsmetode – flere store porer og bedre ledningsevne for vand i jordlaget under pløjedybde.

Micronutrient status in two long-term trials with fertilisation treatments and different cropping systems
Provedor de dados: 21
Autores: Fischer, Meike; Raupp, Joachim; Mäder, Paul; Dubois, David; Römheld, Volker.
Although organic fertilisers always contain micronutrients, we have to pay attention to the question of whether continuous fertilisation will lead to lower contents in plants or lower availability in the long run. We investigated topsoil samples from long-term trials with farmyard manure and mineral fertili-sation and with different organic and conventional farming systems. Input of micronutrients via or-ganic fertilisers was obviously more significant in the case of poor sandy soil than in that of loamy soil with high total contents and higher mineralising potential.

The enhancement and improvement of soil fertility is one of the principal aims of or-ganic agriculture. The practical realization needs a multi-annual, complex approach as well as the economic valuation. Exemplarily, it is shown for the use of green chop with wide C/N ratio in field beans. The cost-benefits-analysis is done with results from field trials and data from real farms. It includes the yield effects on beans and the following grain. Additional impacts like weed suppression and nitrogen fixation are estimated, too. The results show that the gross margin difference for beans is averaged  27 to  55 €/ha (depending on application techniques), but for grains +176 €/ha. Overall, the farms can gain +1 to +13 €/ha in average by using green chop to...

Effect of Water Regime on Aggregate-tensile Strength, Rupture Energy, and Friability
Provedor de dados: 21
Autores: Munkholm, Lars J.; Kay, Bev D.
The effect of water regime on aggregate-tensile strength, rupture energy, and friability index was studied in two experiments on sandy loam soils (Glossic Phaeozem/WRB 1998). In Exp. 1, soil from a long-term, 5-yr crop rotation receiving animal manure (dairy farm and grass, DFG) was compared with a soil (continuous cereal crop, CCC), which had grown almost continuous cereals and not received animal manure. In Exp. 2, soil from compacted plots (PAC) and uncompacted reference plots (REF) was sampled. The soil was air-dried and separated into four aggregate-size classes (i.e., 1–2, 2–4, 4–8, and 8–16 mm). Aggregate-tensile strength and rupture energy were measured on air-dry aggregates and on aggregates adjusted to -10, -30, -100, -350 kPa, and -166 MPa...

Phosphorus supply to organic agriculture:WHAT DOES THE ORGANIC SECTOR THINK ABOUT DIFFERENT PHOSPHORUS FERTILIZERS?
Provedor de dados: 21
Autores: Løes, Anne-Kristin.
Workshops were held in sixEuropean countries participating in the CORE Organic-project IMPROVE-P, to explore the opinions among organic agriculture (OA) stakeholders on recycled fertilizer products. Phosphorus (P) will be depleted over time in soil via export of farm products, and needs replacement to maintain soil fertility. Green waste was the most popular fertilizer product, accepted by more than 90% of the respondents. Least popular was conventional manure from fur animals, but even for this material, more than 30% of the stakeholders were willing to accept its use in OA. There is a large interest among organic stakeholders in fertilizer products derived from human excreta, provided these can be controlled to be safe with respect to food safety issues...

Animal manure for biogas production - what happens to the soil?
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Johansen , Anders; Pommeresche, Reidun; Riley, Hugh.
Utilizing animal slurry to produce biogas may reduce fossil fuel usage and emissions of greenhouse gases. However, there is limited information on how the recycling of digested slurry as a fertilizer impacts soil fertility in the long run. This is of concern because organic matter in the slurry is converted to methane, which escapes the on-farm carbon cycle. In 2010, a study of this question was initiated on the organic research farm in Tingvoll, Norway. So far, a biogas plant has been built, producing anaerobically digested slurry to be compared with undigested slurry in perennial ley and arable crops. Effects on crop yields, soil fauna, microbial communities, soil structure, organic matter and nutrient concentrations are measured.

Modelling Carbon Cycles as Basis of an Emission Inventory in Farms – The Example of an Organic Farming System
Provedor de dados: 21
Autores: Kuestermann, Bjoern; Huelsbergen, Kurt-Juergen.
In organic farms, the internal carbon fluxes are of great importance. They are connected with soil fertility (humus contents, biological activity, soil structure) and the yield potential; some C pools (C fixation in humus) and C fluxes (CO2 and CH4 emissions) may affect the environment. The approach used in the described model software allows to quantify management related and site dependant C fluxes and also the resulting emissions as starting point for an inventory of emissions from farms. The software was validated on the basis of intensive investigations made in the Experimental Farm Scheyern over many years. The results corresponded well to the measured values and characterize Scheyern as a farming system of intensive ecological shaping.

Grondgebonden landbouw is afhankelijk van de ecosysteemdiensten die het natuurlijk kapitaal van de bodem levert. Een gezonde bodem maakt voedingsstoffen vrij, geeft water door, heeft een goede bodemstructuur en het vermogen om ziekten en plagen te onderdrukken. Door gebruik te maken van deze diensten kunnen boeren een aanzienlijke agrarische productie realiseren van een goede kwaliteit. Het bodemleven vormt hierbij een belangrijke spil. We hebben gegevens van 137 melkveehouderijbedrijven onderzocht op de vraag hoe het is gesteld met de bodemgezondheid onder verschillende typen bedrijven.

Regarding a soil compaction survey carried out at the end of 2008 by the Estonian University of Life Sciences in collaboration with the Agricultural Research Centre, soil  compaction was define as one of the currently bigger problems in Estonian soils (Reintam et al., 2010). Soil compaction reduces porosity, permeability and therefore water flow through the soil is blocked, increasing the soil erosion and creating anoxic conditions in the bulk  which causes denitrification, and therefore the uptake of nutrients is reduced (Bakken et al., 1987). In conclusion soil compaction affects directly to the plant root development and crop yield.

Autores: Bliedtner, Marcel; Stalder, Tobias; Mäder, Paul; Fließbach, Andreas; Salazar, Gary; Sönke, Szidat; Zech, Roland.
Soils are one of the largest organic carbon pools and changes in the carbon release from soils has considerable impact on the composition of atmospheric CO2. Alongside the accelerated carbon release from soils by anthro-pogenic warming (Crowther et al., 2016), agricultural use strongly affects soil organic carbon (SOC) (Johnstonet  al., 2009). Conversion from conventional to organic  farming has been suggested a valuable contribution to sequester SOC providing a great mitigation potential within agricultural practices (Smith et al., 2008).Here  we  present SOC contents and 14C activity under two  different farming practices in the long-termagricultural DOK trial at Therwil, Switzerland (Mäder et al., 2002).

Forbedring af jordkvaliteten efter jordpakning - er løsning løsningen?

Autores: Grossmann, Cand. agro. Freya.
Dette speciale beskæftiger sig med jordkvalitet i relation til jordpakning og jordløsninger. Opgavens kapitel 2 behandler definitioner på bæredygtighed og jordkvalitet, og giver tre forskergruppers bud på modelleringer. Modellerne er dog konceptuelle, idet de kun svært kan omsættes til matematiske modeller baseret på data fra praktisk landbrug. Larson og Pierce (1991) opstiller dog et forslag til hvilke målemetoder der skal anvendes i praksis for at undersøge jordkvaliteten. Omfanget af måle-arbejdet gør det realistisk at anvende metoderne i markskala, mens det er urealistisk på regionalt, nationalt og internationalt plan.  På det internationale plan er der til gengæld udviklet et indeks kaldet GLASOD, der kortlægger omfanget af menneskeskabt...

Wat is beter: compost of bokashi?: Bokashi is voedsel voor het bodemleven, compost is geschikt om in te planten
Provedor de dados: 21
Autores: Janmaat, Leen.
Door overmatige aanvoer van diervoeders voor vlees-, ei- en melkproductie, kent Nederland een fosfaatprobleem. Dierlijke mest wordt hierdoor gediskwalificeerd tot afvalstroom, terwijl mest feitelijk een belangrijke grondstof is voor plantengroei. Bij organische mest draait het om de koolstof met daarbij verschillende mineralen waaronder ook stikstof. Afhankelijk van de samenstelling (C/N) werkt organische mest meer als voer voor het bodemleven dan wel als voeding voor de plant. Los van alle mestregels is het streven binnen de biologische sector om zoveel mogelijk biologische mest te gebruiken en daarmee kringlopen op landelijke of regi-onale schaal te sluiten.  De laatste jaren komt ook bokashi in de mode. Enkele biologische boeren zijn de mogelijkheden...

Long term farming systems affect soils potential for N2O production and reduction processes under denitrifying conditions
Provedor de dados: 21
Autores: Krause, Hans-Martin; Thonar, Cécile; Eschenbach, Wolfram; Well, Reinhard; Mäder, Paul; Behrens, Sebastian; Kappler, Andreas; Gattinger, Andreas.
N2O is a potent greenhouse gas with an atmospheric lifetime of 114 years which also contributes to ozone layer destruction. Mitigating N2O emissions is especially challenging to the agricultural sector that is responsible for the majority of anthropogenic N2O release. In order to develop effective mitigation strategies, a detailed understanding of drivers for N2O production and reduction in agriculturally managed soils is needed. Denitrification is recognized as one of the most important source processes for N2O emissions from soils. However, the last step in denitrification, the reduction of N2O to N2 is the only known sink for N2O in soil. Although the impact of single parameters on denitrification is quite well documented, there is still a knowledge gap...

2015 was het vierde jaar waarin de systeemontwikkeling “PlantyOrganic” in praktijk is gebracht. Op de zes percelen zijn de gewassen geteeld die voorzien waren en zijn metingen verricht aan bodem en gewas. De gebruikte meststoffen waren geheel afkomstig vanuit het eigen systeem, zoals in het ontwerp was voorzien. De stikstofbinding door de grasklaver, de motor van het systeem, bleef achter bij de verwachtingen. Daardoor waren de totaal gegeven hoeveelheden stikstof ca. 30 % lager dan waar in het ontwerp van uit is gegaan. De bodemstikstof is getoetst met metingen die in het stikstofmodel NDICEA zijn ingevoerd. De match tussen metingen en berekeningen is voldoende tot goed, met uitzondering van een onverwacht hoge meting in de zomer, na een lange droge...

Effects of animal manure application on springtails (Collembola) in perennial ley
Provedor de dados: 21
Autores: Pommeresche, Reidun; Løes, Anne-Kristin; Torp, Torfinn.
The density and diversity of springtails (Collembola) in the upper soil layer (0–3.8 cm) were studied in a perennial grass-clover ley in NW Norway during April–June 2012. The study was part of a field experiment comparing yields and soil characteristics after application of non-digested slurry (NS) versus anaerobically digested slurry (DS) from dairy cows. In total for three sampling dates, 39 species of springtails were identified. In the Control plots receiving no manure, the density level was around 30 000 individuals (ind.) m2 throughout the whole season. Three days after slurry application (40 t ha -1), the density of springtails had dropped significantly; from 55 214 to 7410 ind. m2 in the NS treatment and from 41 914 to 10 260 ind. m2 in the DS...

The emissions of nitrous oxide (N2O) and leaching of nitrate (NO3) from agricultural cropping systems have considerable negative impacts on climate and the environment. Although these environmental burdens are less per unit area in organic than in non-organic production on average, they are roughly similar per unit of product. If organic farming is to maintain its goal of being environmentally friendly, these loadings must be addressed. We discuss the impact of possible drivers of N2O emissions and NO3 leaching within organic arable farming practice under European climatic conditions, and potential strategies to reduce these. Organic arable crop rotations are generally diverse with the frequent use of legumes, intercropping and organic fertilisers. The...

Autores: Araújo, Ana Leônia de; Oliveira, Renato Teixeira de; Ferreira, Tiago Osório; Romero, Ricardo Espíndola.
Conservation practices are important in improving the environmental protection of agroecosystems in semiarid regions, as these are considered to be fragile environments. Soil-quality indicators are useful elements in evaluating the impact of some agricultural management practices, and the use of recognized indicators which are able to be measured by farmers is an innovative approach that seeks to integrate both scientific and local knowledge. This study aimed to evaluate the impact of various management practices through indicators of soil quality related to soil structure, in areas of family farming where agroecological consortiums are employed. These indicators were identified as important by the farmers themselves, and methodologies were suggested for...

Organic farming effects on clay dispersion in carbon-exhausted soils
Provedor de dados: 21
Autores: Schjønning, P.; de Jonge, L.W.; Olesen, J.E.; Greve, M.H.
Many Danish soils are depleted in organic matter (OM) after decades of intensive cereal cultivation (Schjønning et al., 2009). In this paper we show that clay particles (colloids) in soils that are low in OM content are easily dispersed in the soil water, which in turn has important effects on soil ecosystem functions and services. Organic farming systems generally tend to increase soil OM contents and may thus mitigate the negative effects.

Spatial variability of symbiotic N2 fixation in grass-white clover pastures estimated by the 15N isotope dilution method and the natural 15N abundance method
Provedor de dados: 21
Autores: Hansen, Jacob P.; Vinther, Finn P.
Aiming at estimating the spatial variability in N2 fixation, and to evaluate the appropriateness of the 15N isotope dilution (ID) method and the natural 15N abundance (NA) method in reflecting spatial variability under the influence of cattle grazing, the symbiotic N2 fixation in grass-white clover mixture was studied. At the Foulum site, where the ID method was used, differences in the climatic conditions between the two years of investigations caused a considerable difference in plant growth rates and proportion of clover. Consequently, the total N2 fixation in ungrazed reference plots was significantly less in 1998 than in 1997, being 5.9 and 12.5 g N m-2, respectively. In both years there was a wide range in concentration of inorganic N in the soil...

Evaluation of sustainability: results from long term experimental arable systems in Tuscany
Provedor de dados: 21
Autores: Migliorini, Paola; Vazzana, Concetta.
The research is aimed at implementing a methodology in order to estimate the sustainability of an agricultural system, through the use of Agro-ecological and Sustainability Indicators. The methodology is applied to three stockless, experimental agricultural systems, part of a long-term experiment (MOLTE) managed with diverse typologies (old organic, new organic vs conventional). The results derived from the three different management systems are estimated by considering crop rotation and efficiency in terms of energetic, macro-element (N, P, K) and organic matter flow. These are related to the landscape and biodiversity system, as well as the soil and the environmental system. The research shows that the agro-ecosystems managed with the organic agriculture...

Thanks to positive interactions between species, growing mixtures of cover crops allows improving the ecosystem services provided by cover crop cultivation. In this study, the influence of species diversity but also of species identity and mixture composition on cover crop biomass production and its stability in diverse growing conditions was studied. Several field experiments (varying soil type, preceding crop, soil tillage, sowing density, nitrogen fertilization and spatial replication) were set up in Switzerland during the period 2013−2016. In these experiments, the performance of cover crop species grown as sole crops was compared to that of multispecific mixtures. Part of these experiments followed a simplex design in which four cover crop species...

Assessing soil structure in organically farmed soils
Provedor de dados: 21
Autores: Shepherd, Mark; Hatley, Damian; Gosling, Paul.
This report was presented at the UK Organic Research 2002 Conference. Soil structure was assessed in over 90 fields (organic and conventionally farmed) covering mixed, stockless and pasture farming systems. A combination of spade and an objective scoring system based on the degree of aggregation and porosity was able to detect differences between fields. On average, in the fields sampled, topsoil structure was slightly better on the organic farms though, even on the conventional fields, structure was unlikely to limit crop growth.

In a field experiment based on a five-year crop rotation (pea, potato, barley undersown with red clover, red clover and winter wheat), several soil parameters, porosity, number and biomass of earthworms, total nitrogen, organic carbon, percentage of water stable aggregates and enzymatic activity, were studied during 2013 and 2014, the first and second year, respectively, since the first rotation concluded. This rotation was managed under three organic farming systems: Organic 0 (control), Organic I (with winter cover crops lately incorporated into the soil as green manure) and  Organic II (with the same cover crops plus a yearly amendment of 40 t ha−1 of cattle manure). Crop rotation had a yearly positive effect on the soil bulk density, and enhanced the...

Cover crop mulches and no-till maize
Provedor de dados: 21
Autores: Bortolussi, Stefano.
In a Northern Italian context, a field pea cover crop was tested as mulch for the maize crop. The roller crimper effectively terminated the cover crop (15 t per ha of wet biomass). However, the mulch did not last long enough, probably due to a narrow C/N-ratio and biologically active soil. The maize plants did not have enough time to develop and shade the entire soil surface. Weeds started to sprout through the decomposing mulch. For the test conditions, this cover crop has proven unsuitable as a long-lasting mulch to control weeds. No fertilization and no irrigation were applied. The maize yields amounted to about 5 t per ha.    Practical recommendations  • The cover crop needs to be sown as accurately as the main crop. Poor cover crop stands do not...

Soil Infrastructure, Interfaces &amp; Translocation Processes in Inner Space (“Soil-it-is”): Towards a Road Map for the Constraints and Crossroads of Soil Architecture and Biophysical Processes
Provedor de dados: 21
Autores: de Jonge, L.W.; Moldrup, P.; Schjønning, P.
Soil functions and their impact on health, economy, and the environment are evident at the macro scale but determined at the micro scale, based on interactions between soil micro-architecture and the transport and transformation processes occurring in the soil infrastructure comprising pore and particle networks and at their interfaces. Soil structure formation and its resilience to disturbance are highly dynamic features affected by management (energy input), moisture (matric potential), and solids composition and complexation (organic matter and clay interactions). In this paper we review and put into perspective preliminary results of the newly started research program “Soil-it-is” on functional soil architecture. To identify and quantify biophysical...

Identification of Distinct Functional Microstructural Domains  Controlling C Storage in Soil
Provedor de dados: 21
Autores: Steffens, Markus; Rogge, Derek M.; Mueller, Carsten W.; Höschen, Carmen; Lugmeier, Johann; Kölbl, Angelika; Kögel-Knabner, Ingrid.
The physical, chemical, and biological processes forming the backbone of important soil functions (e.g., carbon sequestration, nutrient and contaminant storage, and water transport) take place at reactive interfaces of soil particles and pores. The accessibility of these interfaces is determined by the spatial arrangement of the solid mineral and organic soil components, and the resulting pore system. Despite the development and application of novel imaging techniques operating at the micrometer and even nanometer scale, the microstructure of soils is still considered as a random arrangement of mineral and organic components. Using nanoscale secondary ion mass spectroscopy (NanoSIMS) and a novel digital image processing routine adapted from remote sensing...

Provedor de dados: 21
Autores: Büchi, Lucie; Wendling, Marina; Amossé, Camille; Jeangros, Bernard; Sinaj, Sokrat; Charles, Raphaël.
To address the inﬂuence of soil tillage reduction on crop yield and soil properties, an experiment was set up in 1969 in the western part of Switzerland. A conventional tillage treatment with plough was compared to a minimum tillage treatment and a deep non inversion tillage treatment, converted to no till in 2007. Evolution of crop yield through time was investigated, as well as the soil properties in 2013. Mean soil properties and their stratiﬁcation with depth were assessed. The results showed that, after 44 years, globally, all tillage treatments allowedtomaintainsimilaryieldsinthelongterm.However,duringthesametime,soilpropertieshavechanged deeply.

The effects of organic farming on the soil physical environment
Provedor de dados: 21
Autores: Papadopoulos, A; Bird, N R A; Whitmore, A P; Mooney, S J.
The aim of this research was to investigate the effects of organic farming practices on the development of soil physical properties, and in particular, soil structure in comparison with conventional agricultural management. The soil structure of organically and conventionally managed soils at one site was compared in a quantitative manner at different scales of observations using image analysis. Key soil physical and chemical properties were measured as well as the pore fractal geometry to characterise pore roughness. Organically managed soils had higher organic matter content and provided a more stable soil structure than conventionally managed soils. The higher porosity (%) at the macroscale in soil under conventional management was due to fewer larger...

Pore characteristics and hydraulic properties of a sandy loam supplied for a century with either animal manure or mineral fertilizers
Provedor de dados: 21
Autores: Schjønning, P.; Iversen, B.V.; Munkholm, L.J.; Labouriau, R.; Jacobsen, O.H.
Application of organic residues to soil is generally assumed to improve soil tilth. Only few studies have reported on the long-term effects on the more subtle aspects of soil porosity and no reports have considered the potential effects of organic amendments on the pore system in the subsoil. We sampled undisturbed soil cores (100 cm3 and 6280 cm3) in metal cylinders in differently fertilized plots in the long-term field experiments at Askov Experimental Station, Denmark. We selected the 0-60 cm soil layer of plots dressed for a century with either mineral fertilizers (labelled NPK) or animal manure (labelled AM). Both fertilization treatments were studied at two levels of nutrient application: 'normal' (labelled '1') and 1.5 times 'normal' (labelled...

Stickstoffnutzungseffizienz roher und anaerob vergorener  Güllen: Eine Studie mit unterschiedlichen 15N Methoden
Provedor de dados: 21
Autores: Hutter, M.; Krebs, R.; Mayer, Jochen.
In agricultural biogas plants in Switzerland, in general 80 % or more of the digested organic matter is farmyard manure. Organic waste materials are used as cosubstrates. A field experiment with silage maize was conducted to test whether the apparent nitrogen use efficiency (NUE) of anaerobically digested slurries is higher than the one of raw slurries in the year of application. Two different 15N labelling  methods were used. In the 15N direct method, slurry NH4-N was labelled. In the indirect 15N isotope dilution method soil was pre-labelled by incorporating 15N labelled  clover-grass powder; maize received unlabelled slurry. In the 15N direct approach, raw slurries had the lowest apparent NUE of NH4-N, two anaerobically digested (AD)  slurries had an...

Response of soil microbial biomass and community structures to conventional and organic farming systems under identical crop rotations
Provedor de dados: 21
Autores: Esperschütz, Jürgen; Gattinger, Andreas; Mäder, Paul; Schloter, Michael; Fließbach, Andreas.
In this study the influence of different farming systems on microbial community structure was analyzed using soil samples from the DOK long-term field experiment in Switzerland, which comprises organic (BIODYN and BIOORG) and conventional (CONFYM and CONMIN) farming systems as well as an unfertilized control (NOFERT). We examined microbial communities in winter wheat plots at two different points in the crop rotation (after potatoes and after maize). Employing extended polar lipid analysis up to 244 different phospholipid fatty acids (PLFA) and phospholipid ether lipids (PLEL) were detected. Higher concentrations of PLFA and PLEL in BIODYN and BIOORG indicated a significant influence of organic agriculture on microbial biomass. Farmyard manure (FYM)...

Estimating legume N2 fixation in a grass-clover mixture of grazed organic cropping systems using two 15N methods.
Provedor de dados: 21
Autores: Vinther, Finn P.; Jensen, Erik S.
The input of N through symbiotic N2 fixation (SNF) in grass-clover mixtures was determined in an organic cropping system for grazing during three years. The mixture of perennial ryegrass (Lolium perenne L.) and white clover (Trifolium repens L.) was established by undersowing in spring barley (Hordeum vulgare L.) and maintained subsequently for two production years. Dinitrogen fixation was determined using the 15N isotope dilution techniques and two labelling procedures. Using either pre-labelling of the soil with immobilisation of the 15N by addition of a carbon source before establishment of the grass-clover mixture or adding the 15N labelled ammonium to the established crop, resulted in similar estimates of the proportion of N derived from the...

Efficient nitrogen use from livestock manure
Provedor de dados: 21
Autores: Askegaard, Margrethe.
This tool is about efficient use of livestock manure, and how optimization will increase yields and reduce nitrogen losses. Thus, the tool is for farmers and their advisors who use livestock manure and higher yields. The tool can be useful regardless of experience.  This factsheet is about optimizing the use of limited amounts of nitrogen from livestock manure. The yield response from applying different amounts of nitrogen differs, hence nitrogen needs to be applied with respect to crop, pre-crop, N-need, soil type, and climatic conditions. The result of optimal N-use is higher yields and less N losses.   The factsheet provides recommendations on yield effective application of livestock manure in relation to nitrogen fixing crops, spring/winter crops, weed...

High Root Biomass FOR cereal crops increases carbon  sequestration in organic Arable systems
Provedor de dados: 21
Autores: Chirinda, N.; Olesen, Jørgen E.; Porter, J.R.
In agroecosystems, soil organic carbon (C) inputs come from applied manures, plant roots and retained shoot residues. Several reasons, associated with root measurements, limit current knowledge on root C input.This study aimed at evaluating root responses to nutrient management and fertility building measures (e.g. catch crops). We made use of one inorganic fertilizer-based and two organic systems in an 11-year-old field experiment on sandy loam soil. At anthesis, soil cores (5 cm dia.) were sampled from 0-30 cm depth within and between rows of winter wheat and spring barley. Roots were separated from soil and washed with tap water, the dry matter (DM) biomass was determined. Dry matter biomass was also measured in shoots.The spring barley root DM was at...

Il suolo, definito dall’Unione europea come la parte più esterna della crosta terrestre, situata tra la roccia o il sedimento inalterato e l’atmosfera, è un sistema naturale complesso, multi-fase, che tende ad auto-organizzarsi in conseguenza dell’azione dei fattori della pedogenesi e in particolare dell’attività biologica, che ne determina i maggiori dinamismi. Non è quindi un mero substrato inerte, statico, attraverso il quale realizzare le produzioni agricole e forestali o sul quale appoggiare le nostre attività e infrastrutture, ma un essere vivente. Il suolo è un patrimonio naturale che si è formato in prevalenza nei millenni precedenti l’Antropocene, l'era geologica attuale, nella quale l'essere umano e le sue attività causano le principali modifiche...

Collembola in grassland – included in the new project SoilEffects
Provedor de dados: 21
Autores: Pommeresche, Reidun; Løes, Anne-Kristin.
Little is known about Collembola in arable soil, at least in Norway. Recently, a study including this group has been initiated in a Norwegian field experiment Soileffects).  Collembola (springtails) are a group of small animals (1-3 mm) living in vegetation,litter and in the pores and caves in the soil to a depth of ca 15 cm. They are important decomposers of dead plant material, eating fungi, algae and  microorganisms in soil and on organic debris. Their grazing and decomposing activity contribute significantly to the nutrient circulation in the soil. The name springtail refers to a furca on their back, usually folded in under the body, but released in need of a rapid escape. In one jump, Collembola can jump more than 50 times their own body length. In...

Autores: Dierauer, Hansueli.
Dem Pflug wird nachgesagt, dass er im Biolandbau die fehlenden Herbizide ersetze. Nicht ganz zu Unrecht, denn nach der Umstellung wird oft mehr gepflügt als vorher. Um die reduzierte Bodenbearbeitung im Bioland zu verbreiten, förderte der Coop Fonds für Nachhaltigkeit über 5 Jahre das FiBL-Projekt «Boden- und klimaschonender Bioackerbau». Neben der Förderung der reduzierten Bodenbearbeitung in der Praxis wurde auch die Wissenslücke über die Bildung von Lachgasemissionen geschlossen.

Greenhouse gas emissions and agronomic feasibility for forage production on inverted peat soil.
Provedor de dados: 21
Autores: Hansen, Sissel; Rivedal, Synnøve; Øpstad, Samson; Heggset, Sverre; Deelstra, Johannes; Dörsch, Peter.
We studied greenhouse gas (GHG) emissions (CH4 and N2O), agronomic performance and soil conditions in a grassland on an inverted peat soil that was earlier cultivated and tile-drained, and compared it with grassland on conventionally tile-drained peat. A neighbouring undrained peat was used as a reference for GHG emissions. Preliminary results (2-year field data) revealed reduced GHG emissions from the inverted peat relative to the tile-drained peat, mainly caused by lower CH4 emissions. Our data suggest that peat inversion can improve the agronomic feasibility of forage production in cool-moist areas with abundant organic soils, and can offer a way of agronomic adaptation to a climate with increased precipitation. At the same time it may reduce the GHG...

Use of a mixture of biotite- and apatite-rich rock powder in a soil with inherent low soil fertility
Provedor de dados: 21
Autores: Bleken, Ass. prof Marina Azzaroli; Krogstad, Prof. Tore; Speetjens, Koen; Heim, Ass. pref. Michael.
Long-term fertility of organically managed soils is challenged by repeated removal of plant nutrients through cash crops. The use of selected rock powders may contribute to maintain soil fertility. A pot trial with Italian ryegrass and white clover was used in order to study the potential of a biotite-rich and of an apatite-rich rock powder to maintain and improve the nutrient supply of organically managed soils.

Um die Effektivität landwirtschaftlicher Anbausysteme zu beurteilen, bedarf es eines Verständnisses der Agrarökosysteme. Eine 21-jährige Studie ergab 20 Prozent geringere Erträge bei ökologischen Anbausystemen gegenüber konventionellen, obgleich der Einsatz von Düngemitteln und Energie um 34 bis 53 Prozent und der von Pestiziden um 97 Prozent geringer war. Wahrscheinlich führen die erhöhte Bodenfruchtbarkeit und die größere biologische Vielfalt in den ökologischen Versuchsparzellen dazu, dass diese Systeme weniger auf Zufuhr von außen angewiesen sind.

DOC-trail: 20 years of organic and conventional farming affect soil microbial properties
Provedor de dados: 21
Autores: Oberholzer, H.R.; Mäder, Paul; Fliessbach, Andreas.
In a long-term field trial (DOC; = bio-Dynamic, bio-Organic, Conventional) at Therwil, Switzerland, agricultural production systems have been compared since 1978. The production systems differ mainly in the amount and form of fertiliser and plant protection strategy. Crop rotation and soil tillage were the same. In the most prominent systems soil microbial properties were investigated for the first time after two crop rotations in 1990. In 1998, after 3 crop rotations, soil microbial properties were investigated in all field plots.  Conclusions  Agricultural systems exert distinct effects on chemical and microbiological soil properties, prominently the bio-dynamic system with the application of composted manure. Part of the influence on microbiological...

Conclusion of chapter 2: "Organic Farming and the Environment"  7 Conclusion  The findings of this study show that organic farming provides a wide range of environmental services. The main results may be summarised as follows:  1. Organic matter content is usually higher in organically managed soils indicating a higher fertility and stability of organic soils, thus reducing the risk of erosion.   2. Organically farmed soils have significantly higher biological activity and a higher total mass of micro-organisms. As a consequence of the higher activity of micro-organisms, in organically managed soils nutrients are recycled faster and soil structure is improved.  3. Organic farming poses no risk of ground and surface water pollution through synthetic...

Autores: Marinari, S.; Papp, R.; Marabottini, R.; Moscatelli, M.C.
The positive effect of Living Mulch on soil microbial biomass and its activity was more evident in the Mediterranean environment starting from the main crop planting (t1) . Conversely, in the Northern site the effect of LM was significant in not tilled soil at the main crop harvesting (t2). These preliminary results establish the bases for the final evaluation at end of the project, on the importance of pedoclimatic conditions to prove the effect of Living Mulch at different tillage levels.

Effect of incorporating rice straw or leaves of gliricidia (g. Sepium) on the productivity of mungbean (vigna radiata) and on soil properties
Provedor de dados: 21
Autores: Sangakkara, U. R.; Pietsch, G.; Gollner, M.; Freyer, B.
A field study evaluated the impact of mulching or incorporating two organic materials with differing C:N ratios on selected soil properties and the productivity of organically grown mungbean in a dry season, under rainfed conditions. While the organic matter improved the soil parameters and hence yields, incorporation had a greater beneficial impact on measured parameters, except weed numbers, which were reduced significantly by mulching with straw. Gliricidia leaves, with a lower C:N ratio than rice straw, had the better effect on soil properties and crop growth. The potential for using commonly available organic materials in smallholder tropical cropping systems to enhance productivity in dry seasons is discussed.

Soil properties at the beginning of the MEE (Multi Environment Experiments) were statistically analyzed in order to verify the field homogeneity. The initial soil properties represent the starting point to interpret the effect of CC and LM on soil fertility during crop cycle.Soil properties of the fields were quite homogeneous at the beginning of crop cycles (first and second).  The soil properties of the experimental fields in the selected areas showed a wide variety of pedons to be used for the comparison of CC and LM effect in different climate zones.  Soils from the Northern European sites are more acid and richer of nutrients and organic matter with respect to the soils in Southern sites.

The DOK long-term field trial in Switzerland started in 1978 (Mäder et al., 2002). Biodynamic (BIODYN), bioorganic (BIOORG) and integrated (CONFYM) farming systems with manure fertilization, an integrated system based on mineral fertilizer only (CONMIN) and an unfertilized control (NOFERT) were investigated for changes in soil organic matter and on the structure of the soil microbial communities. Soil organic matter (SOM) in the Ap-horizon (0-20 cm) was analysed from the beginning of the DOK field trial in 1978. Roughly 20% of the initial SOM was lost when no manure was applied for 21 years as in the CONMIN and the NOFERT system, whereas SOM increased slightly by 4% in the BIODYN system that makes use of composted farmyard manure, corresponding to 1.4...

Pilot Experiments with Electrodialysis and Ozonation for the Production of a Fertilizer from Urine
Provedor de dados: 21
Autores: Pronk, W.; Zuleeg, S.; Lienert, J.; Escher, B.; Koller, M.; Berner, A.; Koch, G.; Boller, M.
Pilot tests were performed with a process combination of electrodialysis and ozonation for the removal of micropollutants and the concentration of nutrients in urine. In continuous and batch experiments, maximum concentration factors up to 3.5 and 4.1 were obtained, respectively. The desalination capacity did not decrease significantly during continuous operation periods of several weeks. Membrane cleaning after 195 days resulted in approximately 35% increase in desalination rate. The Yeast Estrogen Screen (YES), a bioassay that selectively detects oestrogenic compounds, confirmed that about 90% of the oestrogenic activity was removed by electrodialysis. HPLC analysis showed that ibuprofen was removed to a high extent, while other micropollutants were...

Organic matter and soil tilth in arable farming: Management makes a difference within 5-6 years
Provedor de dados: 21
Autores: Schjønning, P.; Munkholm, L.J.; Elmholt, S.; Olesen, J.E.
Management-induced depletion in soil organic carbon (SOC) may create critical tilth conditions for arable farming. We investigated the short-term effect of crop rotation and addition of animal manure on SOC fractions, the dispersibility of soil clay, the length of fungal hyphae, wet aggregate stability, tensile strength of dry aggregates, and the pore size distribution, gas diffusivity and permeability of undisturbed bulk soil. SOC fractions were measured in whole-soil samples and in 1-2 mm air-dried aggregates. Plough layer soil was sampled five and six years after the start of a field experiment with different cropping systems at two loamy sand soils (Foulum, ~9% clay and Flakkebjerg, ~14% clay). A soil drop test was performed in the field to evaluate in...

Annual self-reseeding legumes and their application into mediterranean cropping systems.
Provedor de dados: 21
Autores: Driouech, Noureddin.
Soil fertility management is a major concern in organic farming. According to the EEC Regulation 2092/91, soil fertility must be maintained and/or increased by legumes cultivation. Native Mediterranean legumes ecotypes are more persistent than commercial varieties but their use in catch crop sequences is still limited. The N2-fixing legumes crops as a local resource can be considered as an alternative to improve nitrogen nutrition and to increase crop yields. This study aimed to investigate the agronomic performance of seven annual self-reseeding legumes and the short–term effect of nitrogen supply on the subsequent crops. Results are presented from field experiment on sandy-clay soil, pH 8.1 and 1.6% of organic matter, in the south of Italy, where the...

Isolation and characterization of labile organic phosphorus pools in soils from the Askov long-term field experiments
Provedor de dados: 21
Autores: Guggenberger, Georg; Christensen, Bent T.; Rubæk, Gitte H.
Labile soil organic phosphorus (Po) plays a crucial role in plant P nutrition and in environmental eutrophication. This paper discusses recent studies on the nature of labile soil Po and its response to different fertilization practices. Soil material was obtained from the Askov long-term experiment on animal manure and mineral fertilizers. Our analytical approach combined a macroporous anion exchange resin to isolate labile Po and 31P NMR spectroscopy to assess the chemical composition and origin of NaOH-extractable Po. The analyses were carried out on fine earth (&lt;2 mm) and particle-size fractions. The results suggest that the resin extraction isolates an active pool of soil Po that consists primarily of microbially-derived compounds. The size of the...

Organic no-till systems
Provedor de dados: 21
Autores: Moyer, Jeff.
Organic farming has relied heavily on tillage for weed control while conventional no-till techniques depend entirely on herbicides for weed control and effective cover crop kill. The challenges have been how to make the benefits of no-till accessible to organic farmers. Jeff Moyer, Rodale Institute, explains how organic no-till works, using sound biological principles and mechanical cover-crop termination, to reduce and even eliminate tillage. The system works well for soybean and requires further investigation for other crops. This is an advanced technique and requires some skills to be successfully applied, but it will probably be the way to grow many field crops.

Field trials on reduced soil tillage under organic farming conditions across Europe were used to compare the soil quality changes over time. Soil organic carbon fractions, soil carbon stocks and microbial community structure were analysed. Most severe differences between plough and reduced tillage were found in the top ten cm of the soil profile. Differences became less or not significant in deeper layers. Analyses are still ongoing and will only be ready to be presented at the conference.

Autores: Kainz, Max; Siebrecht, Norman; Reents, Dr. Hans Jürgen.
Soil erosion is often calculated by models. Those are up to now not reflecting the  specific conditions of Organic Agriculture (OA). The aggregate-stabilizing effect of  grass-clover ley, which is a crucial crop for OA, is considered much greater than  implemented in the models. Other factors not included in models include, the effects of  organic instead of mineral fertilizers, the non-use of pesticides and soil cover by  specific crops and weeds. This paper gives a first overview about the modifying effects  of organic farming on soil erosion.

Ripristino della funzionalità ottimale del suolo in aree degradate di vigneti biologici
Provedor de dados: 21
Autores: Priori, S.; Fantappiè, M.; Agnelli, A.E.; Costantini, E.A.C.
Il progetto ReSolve ha voluto testare tre diverse pratiche agronomiche biologiche per il recupero di aree di vigneto con suoli degradati, per cause legate allo scasso, ai livellamenti e all’erosione. L’obiettivo primario per il recupero di queste aree è quello di aumentare la dotazione di sostanza organica nel suolo, così da migliorarne la struttura, l’areazione, la fertilità chimica e l’attività biologica.  Le pratiche testate sono state: la forte aggiunta di compost, in quantità di circa 40 tonnellate ad ettaro; un sovescio con leguminose e graminacee (in Italia orzo e favino); una copertura con leguminose riseminanti per il taglio pre-estivo e la pacciamatura secca dell’interfilare.   Dopo due anni di prove, è stato osservato un grande incremento di...

Long-term soil accumulation of potentially toxic elements  and selected organic pollutants through application of recycled phosphorus fertilizers for organic farming conditions
Provedor de dados: 21
Autores: Weissengruber, Lina; Möller, Kurt; Puschenreiter, Markus; Friedel, Jürgen K.
The pollutant input and the risk of contamination by long-term application of recycled P fertilizers (RPFs) in European agricultural soils were estimated by a mass balance approach. Calculations based on literature data were carried out for the potentially toxic elements (PTEs) Cd, Cr, Cu, Ni, Pb, Zn and for the persistent organic pollutants (POPs) PCBs, PAHs and polychlorinated dibenzo-dioxins and -furans. The PTE accumulation estimation during 200 years of fertilizer application, equivalent to 11 kg P ha-1 year-1, the mean P export via harvested products on European stockless organic farms, regarded soil background concentrations and proposed threshold concentrations. For PTEs, inputs were fertilizer application, atmospheric deposition and liming, output...

HOW TO RESTORE SOIL FUNCTIONALITY IN DEGRADED AREAS OF VINEYARDS
Provedor de dados: 21
Autores: Costantini, E.A.C.; Priori, S.; Fantappiè, M.
In both conventional and organic vineyards, it is quite common to have areas characterized by problems in vine health, grape production and quality, often caused by improper land preparation before vine plantation and/or management. Causes for soil malfunctioning can include: reduced contribution of the soil fauna to the ecosystem services (i.e. nutrient cycles), poor organic matter content, imbalance of some element ratio, altered pH, water deficiency, soil compaction and/or scarce oxygenation.  ReSolVe is a transnational and interdisciplinary 3-years research project of the within the FP7 ERA-Net CORE Organic Plus aimed at testing the effects of selected organic strategies for restoring optimal soil functionality in degraded areas within vineyard.

Autores: Beste, Andrea.
Die Zunahme von Überschwemmungen entwickelt sich mehr und mehr zu einer Bedrohung  der Lebensqualität in Europa. Viel Geld wird in den technischen Hochwasserschutz investiert,  um Dämme, Schutzmauern oder Rückhaltebecken zu bauen. Auch die Diskussion um  die Flächenversiegelung findet ein breiteres Echo. Was jedoch leider kaum Eingang in die  Diskussion findet ist die Tatsache, dass nicht nur die Flächenversiegelung für Siedlungs- und  Verkehrsflächen oder mögliche Klimaveränderungen für die Zunahme von Hochwasserereignissen  verantwortlich sind, sondern in großem Maße die verminderte Wasseraufnahme-,  Speicher- und Filterfähigkeit unserer land- und forstwirtschaftlich intensiv genutzten Böden.

The aim of this study conducted at the experimental farm in Scheyern, was to investigate whether earthworm population in different habitats and under different farming systems (organic vs. integrated) differs. Arable land was compared with alley cropping systems, with meadows and field margins. For comparison purpose there were also investigations on the natural habitats fallow, forest and forest edge. The field study yielded the following results: In the meadow, the tree row in the alley cropping system and in the natural reference habitats (with exception of the studied forest), the abundance and species diversity was enhanced compared with arable land. In addition the tree rows in the alley cropping system had a positive effect on the earthworm...

Understanding soil nitrogen supply: organic matter quality and quantity
Provedor de dados: 21
Autores: Hatch, David; Shepherd, Mark; Hatley, Damian.
This report was presented at the UK Organic Research 2002 Conference. The soil organic matter (SOM) contents of organic and conventionally farmed soils were compared. Whilst the quantity of SOM was found to be similar with both systems, the quality of SOM differed in respect of higher amounts of N released by the organic soils under anaerobic incubation. This indicated a greater potential rate of mineralization and suggested that the inherent fertility of the organic soils had been improved

Soil organic matter and biological soil quality indicators after 21 years of organic and conventional farming
Provedor de dados: 21
Autores: Fliessbach, Andreas; Oberholzer, Hans-Rudolf; Gunst, Lucie; Paul, Mäder.
Organic farming systems often comprise crops and livestock, recycle farmyard manure for fertilization, and preventive or biocontrol measures are used for plant protection. We determined indicators for soil quality changes in the DOK long-term comparison trial that was initiated in 1978. This replicated field trial comprises organic and integrated (conventional) farming systems that are typical for Swiss agriculture. Livestock based bio-organic (BIOORG), bio-dynamic (BIODYN) and integrated farming systems (CONFYM) were compared at reduced and normal fertilization intensity (0.7 and 1.4 livestock units, LU) in a 7 year crop rotation. A stockless integrated system is fertilized with mineral fertilizers exclusively (CONMIN) and one control treatment remained...

Sorption of dissolved organic C and P to agricultural top- and subsoil
Provedor de dados: 21
Autores: Gjettermann, Birgitte; Styczen, Merete; Hansen, Søren; Borggaard, Ole K.; Hansen, Hans C.B.
In order to study the mobility of dissolved organic carbon (DOC) and dissolved organic P (DOP) in soil, the pH-dependent sorption of dissolved organic matter to an agricultural top- and subsoil was investigated. In general, sorption isotherms had convex shapes and DOC and DOP sorption increased with time of reaction. There was a very pronounced effect of pH resulting in much higher sorption of DOC at pH 5 than at pH 7; actually extensive desorption was observed at pH 7 especially for the topsoil. Similar sorption patterns were observed for DOP, but they were not as pronounced as for DOC.

Humusersatzstrategien im viehlosen Ökolandbau
Provedor de dados: 21
Autores: Brock, Christopher; Dannehl, Theresa; Blumenstein, Benjamin; Möller, Detlev.
Soil organic matter management is a challenge especially in stockless organic farming systems, as shares of fodder legumes in crop rotations are often small to provide  more cash crop area, and farmyard manure as the most valuable source for organic matter supply to soils is not available. However, there are many different options for  stockless farms to tackle this challenge. In this article we discuss strategies for organic matter supply to soils based on scenarios for different soil-climate regions in Germany.  We conclude that the integration of fodder legumes into crop rotations is the most valuable option, as these crops do not only provide carbon but are able to replace mineralized soil organic matter nitrogen that has been exported with the...

Effects of digestate from anaerobic digested cattle slurry and plant materials on soil microbiota and fertility
Provedor de dados: 21
Autores: Johansen, Anders; Carter, Mette S.; Jensen, Erik Steen; Hauggaard-Nielsen, Henrik; Ambus, Per.
Anaerobic digestion of animal manure and crop residues may be employed to produce biogas as a climate-neutral source of energy to provide fertilizers which allow recycling of plant nutrients on the farm. However, compared to fertilizing with the pristine input materials (e.g. raw animal slurry or plant residues), the effect on soil microbiota and soil fertility may be impacted due to the increased content of mineral nitrogen (N) and decreased amount of organic carbon (C); an issue of concern in especially organic farming systems.  An incubation study was performed where 1) water, 2) raw cattle slurry, 3) anaerobically digested cattle slurry + maize, 4) anaerobically digested cattle slurry + grass-clover, or 5) fresh grass-clover was applied to soil at...

Inside a long-term agronomic trial aimed at evaluating the effects of organic and low-input conventional management systems on soil fertility and arable crop production, we selected six fields bordered by hedgerows, three under each management system. Here, we analyzed the carabid assemblages and the slug abundance. Samplings took place in five different periods, across 1 yr of observations. The carabid abundances were similar in organic and conventional fields. The Shannon–Wiener diversity index (H’) showed a higher value in the conventional fields, although in the organic fields, a higher number of species were observed. The multivariate analysis described similar carabid communities, but excluding the period factor, it showed a significant influence of...

Soil Fragmentation and Friability. Effects of Soil Water and Soil Management
Provedor de dados: 21
Autores: Munkholm, Lars J.
Soil fragmentation is a primary aim in most tillage operations in order to create a soil environment favourable for crop establishment and growth. Soils vary around the world from those exhibiting a self-mulching nature to those of a hardsetting nature. These extremes have been reported for Australian and other tropical and subtropical soils. In humid temperate climates, soil tillage is generally needed in order to produce a favourable environment for crop establishment and growth. The ease of preparing a favourable arable layer depends on complex interactions between climate, soil and the tillage implement. Especially soil water affects soil strength and fragmentation properties and thereby the ease of preparing a suitable arable layer. Soil management...

Soil microbiological analyses may serve as a means for assessing soil characteristics. Standard microbiological culture-techniques, however, leave over 90% of the microorganisms in the environment unaccounted for. Several more recently developed analytical techniques such as DNA, phospholipid fatty acid (PLFA), and community level substrate utilization (CLSU) Ængerprints allow for more detailed analyses of soil microbial communities. We applied analyses of (1) community DNA with PCR and restriction fragment length polymorphism (RFLP), (2) community PLFAs with gas chromatography and mass spectrometry, and (3) CLSU with Biologe gram-negative-plates, to evaluate the biological characteristics of three soils used in pesticide degradation studies.

Do Farm Management Practices Alter Soil Biodiversity and Ecosystem Function?   Implications for Sustainable Land Management
Provedor de dados: 21
Autores: Philipps, Ms Lois; Stockdale, Dr Elizabeth A.; Waston, Dr Christine A.
Maintaining ecosystem functions is a key issue for sustainable farming, while recent reviews (Hole et al, 2005, Fuller et al 2005) have highlighted that a wide range of taxa, including birds and mammals, benefit from organic management of land, there is a need to bring together the evidence for the impact of agricultural management practices on belowground biodiversity. A focus simply on the biodiversity of below-ground species is however not enough and there is a need to consider the contribution of below-ground biological processes to the maintenance and enhancement of a range of ecosystem services. A recent literature review on the impacts of land management practices on soil ecology and function shows clearly that farm management practices do alter...

Soil quality indicators in organic and conventional farming systems in Slovakia
Provedor de dados: 21
Autores: Lehocka, Zuzana; Klimekova, Marta; Bielikova, Magdalena.
In this study we compare some chemical and biological soil properties using the organic and conventional systems. In 2003 and 2004 the soil characteristics were observed on the precise field experiment plots in Borovce (near Piešťany, in the western part of the Slovak Republic) where organic management has taken place since 1995. The soil representative is loam and clay, loam degraded Chernozem on loess. The chemical and biological soil properties were determined within two farming systems: organic and conventional. The lower values of soil reaction and the higher contents of organic matter and inorganic nitrogen in the soil were measured under organic treatment. Organic management also positively affected a number of the cellulolytic and ammonification...

Matching nitrogen demand of plants and N release of organic fertilizers with respect to amount and timing is one key for successful cultivation of organic ornamentals. Thereby for plants with a low to moderate N demand growers can add the fertilizer as complete preplant application (CPA). For plants with a high N demand splitting fertilization in a reduced preplant application combined with an additional fertigation (RPA+F) is preferable. Aim of the current research was the investigation of N release of organic fertilizers in incubation experiments. Results of the incubation experiment were linked to a pot trial with pelargonium. Incubation experiments reveal that most  fertilizers release about 40 to 50 % of total N and most nitrogen is released within...

Karbonlagring i jord er avhengig av både planter og jordliv
Provedor de dados: 21
Autores: Pommeresche, Reidun; Riley, Hugh.
Det er ikke så enkelt å lagre karbon i jord. Både i kjøkkenhagen og i bondens åker er karbonholdige molekyler ettertraktede energikilder og byggeråstoff for organismene i jorda. Karbon tilfører vi gjennom husdyrgjødsel, kompost, jorddekke og via røttene til levende planter. Bare en liten del av karbonet vi tilfører jorda, det som skjermes for omdanning i såkalt stabil humus, vil være igjen i jorda etter noen år. Et viktig resultat av biologisk aktivitet i jorda, både plantevekst og all annen aktivitet, er dannelse av humusmolekyler.   Det er fra naturens side ingen automatikk i å lagre store mengder karbon i jord hvor det samtidig produseres og høstes store avlinger. Karboninnholdet i jord bestemmes av likevekten mellom det som tilføres og det som brukes i...

In Italian vineyards, it is quite common to have areas characterized by problems in vine health, grape production  and quality, often caused by improper land preparation before vine plantation and/or management. Causes for soil  malfunctioning can include reduced contribution of the soil fauna to the ecosystem services such as nutrient cycles  and organic matter turnover.  ReSolVe is a transnational and interdisciplinary project, supported by Core-Organic+ program, aimed at testing the  effects of selective agronomic strategies for restoring optimal soil functionality in degraded areas within organic  vineyard. For this purpose, the evaluation and biomonitoring of the abundance of soil mesofauna, nematodes  and microarthropods, represents an efficient tool...

En bekvem jord: hvad betyder det og hvordan opnås det
Provedor de dados: 21
Autores: Schjønning, P.; Munkholm, L.J.; Elmholt, S.
Ensidige sædskifter uden brug af husdyrgødning har vist sig at udpine jorden så meget, at der (bl.a.) bliver problemer med jordens evne til at smuldre under bearbejdning. Økologiske sædskifter vil oftest være så alsidige, at man dér vil opretholde en passende pulje af nydannet, ’aktivt’ organisk stof. Tildeling af husdyrgødning trækker i samme retning. Mekanisk påvirkning af jorden kan eliminere eller i hvert fald reducere de gode effekter af sædskiftet. Der er derfor al mulig grund til at begrænse skadelig pakning af overjorden mest muligt (brug brede lavtryksdæk) samt – om muligt – at undgå brugen af fræser og rotorharver.

In 2014 the N2 fixation of spring faba beans was elevated according to high grain yields, especially in pure stands. In 2015 grain yields and symbiotically fixed N2 were  on a low level due to stress (drought, aphids). Intercropping faba beans with oat in alternate rows evoked an increasing proportion of nitrogen derived from the atmosphere compared to faba beans in pure stands. N2 fixation of faba beans at  maturity did not differ significantly between deep ploughing and reduced tillage.

Multi-level assessment of soil quality – linking reductionistic and holistic methodologies
Provedor de dados: 21
Autores: Schjønning, Per; Munkholm, Lars J.; Debosz, Kasia; Elmholt, Susanne.
Soil quality is often used as a qualitative, general term. However, quantification is an important feature of the scientific approach to nature. On the other hand, addressing specific soil parameters as indicators of soil quality includes a reduction of the whole soil system. Therefore, results obtained by specialized methodologies ought to be evaluated by methods integrating the soil characteristics in situ. In this presentation, results are given from an investigation of the tilth of two differently managed loamy soils. One of the soils had been managed for decades with a forage crop system (labeled FCS), which included fertilization with farmyard manure, while the other had been grown with a continuous cereal system (labeled CCS), receiving no input of...

NEMATODE COOMUNITIES AS INDICATORS OF SOIL QUALITY IN VINEYARD SYSTEM: A CASE OF STUDY IN DEGRADED AREAS
Provedor de dados: 21
Autores: Landi, S.; D'Errico, G.; Simoncini, S.; L'Abate, G.; Priori, S.
The restoring effect of selective agronomic strategies on optimal soil functionality of degraded areas within organic vineyard was evaluated using the nematode community as an indicator of soil quality.  Three different restoring strategies were implemented in two organic farms located in Tuscany (Italy). The relative abundance of nematode trophic groups and the maturity index showed that the use of compost improved soil biological quality and increased the abundance of predators. Instead, dry mulching and green manure applications were useful to control the most dangerous nematodes of grapevines, namely the virus-vector Xiphinema index (Longidoridae).

The importance of amino-N for humus formation studied by comparing amino-N input to the soil and soil total nitrogen content in long-term experiments
Provedor de dados: 21
Autores: Schuler, Christiana; Raupp, Joachim; George, Eckhard.
Humus formation is thought to depend directly on carbon input. Referring to earlier studies we tested the role of amino-bound nitrogen (amino-N) input to the soil using data of 10 long-term experiments with different fertilization and crop rotation treatments. In 8 out of the 10 experiments there was a significant positive correlation between the amino-N input and soil total N content. This correlation was much stronger than the one of total N input and soil N content, indicating that amino-N was more important for soil N accumulation than total N input. Amino-N from farmyard manure seems to be more effective in this respect than amino-N from other organic fertilizers.

Nitrate leaching from organic farming systems with rotational grass-clover and arable crops
Provedor de dados: 21
Autores: Berntsen, J.; Grant, R.; Olesen, J.E.; Kristensen, I.S.; Vinther, F.P.; Mølgaard, J.P.; Petersen, B.M.
Organic farming is considered an effective mean of reducing nitrogen losses compared with more intensive conventional farming systems. However, under certain conditions organic farming may also be susceptible to high nitrogen (N) losses. This is especially the case for organic dairy farms on sandy soils that use grazed grass-clover in rotation with cereals, which may lead to high rates of nitrate leaching.   A study was conducted on two commercial organic farms on sand and loamy sand soils. On each farm a three year old grass-clover field was selected. Half of the field was ploughed the first year and the other half was ploughed the next year. Spring barley (Hordeum vulgare L.) was sown after the spring ploughing. Measurements showed a low N leaching...

A method for soil health assessment in the conversion to organic farming
Provedor de dados: 21
Autores: Mata, Macarena; Garrido, Marisol; Longhurst, Phil; Seaton, Roger.
This paper was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR).  The regulation for the assessment of the conversion to organic farming establishes the use of soil/produce pollution and the type of agricultural practices as indicators of performance. However, these indicators don’t reflect the complexity of the soil ecosystem and soil health. Therefore, complementary indicators were sought (soil biostructure and field capacity), and a specific three-steps method for the assessment and monitoring of soil health during the conversion process was developed.

After a completed rotation of seven years, soils of the Manure as a Chance (MAC) trial were analysed for the effect of organic amendments on soil physical, chemical and biological properties. Yields suggest significant differences due to different organic amendments after seven years. In treatments receiving farm yard manure and bio waste compost yields increased over time. Soil properties indicate changes in soil carbon, nitrogen mineralization en plant feeding nematodes due to different organic amendments. No significant changes in microbial and fungal biomass were found.

In our study we investigated the effect of soil phosphorus (P) status on legume occurrence and on phytodiversity of organically managed permanent grassland sites. Therefore, we realized screenings on 2 m x 2 m plots with a clear spatial  differentiation between the functional groups ‘legumes’ and ‘non-legumes’ on five mown pasture sites under organic management in north-eastern Germany. We found no significant difference between the phosphorus content of aboveground biomass of legumes and the associated non-legume group. However, we detected a significant difference between the soil PDL contents of these two groups with lower contents in  soils of the legume patches whereas the different P fractions and thus different P availability on the mineral site...

Weeds as soil bioindicators: How to sample and use data
Provedor de dados: 21
Autores: Carlesi, Stefano; Barberi, Paolo.
This technical note shows how weed species can be used as indicators of soil conditions that are either linked to soil characteristics (such as soil pH or texture) or to soil management (such as water logging, lack or excess of nutrients, compaction).   It should be stressed that (i) this kind of analysis does not always provide consistent results, because the relationship between weed species and soil conditions is not always clear cut and that (ii) the suggested sampling methodology requires some basic botanical skills for weed identification.

Ground Beetle (Coleoptera: Carabidae) Assemblages and Slug Abundance in Agricultural Fields Under Organic and Low-Input Conventional Management Within a Long-Term Agronomic Trial in Central Italy
Provedor de dados: 21
Autores: Rossi, Elisabetta; Antichi, Daniele; Loni, Augusto; Canovai, Roberto; Sbrana, Massimo; Mazzoncini, Marco.
Inside a long-term agronomic trial aimed at evaluating the effects of organic and low-input conventional management systems on soil fertility and arable crop production, we selected six fields bordered by hedgerows, three under each management system. Here, we analyzed the carabid assemblages and the slug abundance. Samplings took place in five different periods, across 1 yr of observations. The carabid abundances were similar in organic and conventional fields. The Shannon–Wiener diversity index (H’) showed a higher value in the conventional fields, although in the organic fields, a higher number of species were observed. The multivariate analysis described similar carabid communities, but excluding the period factor, it showed a significant influence of...

A model analysis on nitrate leaching under different soil and climate conditions and use of catch crops
Provedor de dados: 21
Autores: Pedersen, Anders; Stoumann Jensen, Lars; Thorup-Kristensen, Kristian.
The use of crops and catch crops with deep rooting can strongly improve the possibility of retaining nitrate-N that will otherwise be leached to the deeper soil layers and end up in the surrounding environment. But will it always be an advantage for the farmer to  grow a catch crop? This will depend on factors such as soil mineral nitrogen level, soil water holding capacity, winter precipitation, rooting depth and N demand of the scceeding crop. These factors interact, and it can be very difficult for farmers or advisors to use this information to decide whether growing a catch crop will be beneficial. To analyse the effect of catch crops under different Danish soil and precipitation conditions, we used the soil, plant and atmosphere model Daisy.

Spatial variability of microbial indicators and assessment of tillage systems on the soil microbiological functioning on organic farming.
Provedor de dados: 21
Autores: VIAN, Ph D Jean François; PEIGNE, Dr Joséphine; CHAUSSOD, Dr Rémi; DAVID, Dr Christophe; ROGER-ESTRADE, Pr Jean.
Reduction tillage, in modifying the soil microorganisms’ environment, modifies their potential to supply plants nutrients. This is of primary importance in organic farming as the nutrients availability is mainly dependent on the organic matter degradation by microorganisms. To study the effect of tillage on soil physical and microbiological properties, we compare 4 tillage practises (deep and shallow ploughing, chisel and no tillage) in an experimental field near Lyon. Our objective is to link a structural statement with a microbiological functioning in order to study the microorganisms’ abilities to supply nitrogen and phosphorus. For such studies, it is of primary importance to use a convenient sampling design as the microbiological properties are highly...

Viehhaltung im Ökologischen Landbau - ja oder nein?  Effekte auf Bodenfruchtbarkeit, N-Bilanzen und Erträge
Provedor de dados: 21
Autores: Schulz, Franz; Brock, Christopher; Leithold, Günter.
An organic long-term field experiment with two factors has been carried out since 1998 at the experimental station Gladbacherhof, University of Giessen. Effects of different farm types (with and without lifestock raising) combined with tillage treat-ments on plants, soil and environment have been investigated. This article presents results on soil fertility, N-balances and cash crop yields according to the farm system. All in all, the superiority of a management system with cattle over stockless organic farming is demonstrated. The mixed farm type led to higher amounts of humus in the soil, lower N-losses and higher yields. Unless stockless farming cannot be avoided a mulched grass-legume ley, in combination with grain- and fodder legumes as main or...

After reclamation of open-cast mining pits, soil formation starts from the deposited calcareous loess characterised by its basic physical and chemical properties whereas soil biology and structure need to develop to achieve a fully functional soil. In this study we used a chronosequence approach to elucidate soil formation on agriculturally reclaimed loess soils in an open-cast lignite mining area in Garzweiler (Germany). We selected six fields aged 0, 1, 3, 6, 12, and 24 years after the first seeding in order to observe the initial stage of development of soil properties and assess the role of management with conventional crop rotation in soil structure formation and soil organic carbon (SOC) accumulation. Loess parent material had a strong impact on...

In a long-term field trial (November 2002-2011), located in Frick near Basle (Switzerland), the influence of reduced tillage on soil fertility and yield is studied in a crop rotation under organic farming conditions. Here, we describe the field experiment and present results of the first year. The three factors examined, soil tillage, manure type and biodynamic preparations are implemented in a fully factorised experimental setup. The experimental field manifested a high homogeneity for the parameters pH, soil organic carbon (Corg), dehydrogenase activity and microbial biomass.  Wheat yield in the first experimental year was 16% higher in ploughed plots than in the plots with reduced tillage (p &lt; 0.001). Plots fertilised with slurry manifested 5 % (p...

Restmaterialer fra bio-energiproduktion - kan de tilbageføres til marken?
Provedor de dados: 21
Autores: Johansen, Anders; Hansen, Christian M.; Carter, Mette S.
Efluents from biogas production may be recycled to soil as plant nutrition. However, the proportion of plant-available nitrogen is high and may cause loss due to leaching or gaseous emissions. Hence, such waste stream materials must be applied with care to ensure maximum plant uptake to minimize loss. Spread of weed seeds via application of biogas effluents is only a problem when the digestion is performed at mesophilic conditions and when the seeds are staying less than a week in the plant. At thermophilic conditions, seeds from a range of weed plant were unable to germinate efter just a few days.

Autores: Hijri, Isabelle; Sýkorová, Zuzana; Oehl, Fritz; Ineichen, Kurt; Mäder, Paul; Wiemken, Andres; Redecker, Dirk.
Communities of arbuscular mycorrhizal fungi (AMF) in five agricultural field sites of different management intensities were studied. Variable regions of the ribosomal RNA genes were used to detect and identify AMF directly within colonized roots. Roots from a continuous maize monoculture showed low AMF diversity, in agreement with previous reports on molecular diversity of AMF in agricultural soils. In contrast, a substantially higher diversity of AMF was found throughout the long term `DOK' field experiment, where organic and conventional agricultural practices have been compared side by side since 1978. In this experiment, a 7-year crop rotation is performed under lower levels of inorganic fertilizer input and chemical pest control. These results are in...

Modelling soil pore characteristics from measurements of air exchange: the long-term effects of fertilization and crop rotation
Provedor de dados: 21
Autores: Schjønning, P.; Munkholm, L.J.; Moldrup, P.; Jakobsen, O.H.
Long-term cultivation of soils for arable crops and without application of organic manure is thought to reduce the soil quality for crop production. We studied the porosity of two sandy loam soils from organic dairy farms with a ley cropping system and compared them with a conventionally managed dairy farm growing arable crops only and an arable soil receiving only mineral fertilizers, respectively. Saturated hydraulic conductivity, water retention characteristics, air diffusivity and air permeability were determined in the plough layer of the soil.    The soil of one of the organic dairy farms contained many more earthworm burrows and had a significantly larger hydraulic conductivity than the counterpart soil of the conventionally managed dairy farm.

Bedeutung von Mykorrhiza-Pilzen für Rotklee-Gras-Mischungen
Provedor de dados: 21
Autores: van der Heijden, Marcel; Wagg, Cameron; Lukasiewicz, Kasia; Olbrecht, Luise.
Grass-clover pastures form an essential part of organic farming systems. It is well known that nitrogen fixing bacteria play a key role in determining productivity of grass-clover pastures. Yet, the impact of other plant symbionts, such as arbuscular mycorrhizal (AM) fungi, on grass-clover is still poorly understood. Here we demonstrate that AM fungi enhanced red clover biomass and enabled red clover to coexist with grass. Moreover, the diversity of AM fungi in the soil promoted productivity of grass-clover mixtures. Inoculation experiments in a range of field soils with native AM fungi showed that addition of AM fungi promoted clover biomass in several (but not all) soils. This study shows that AM fungi can be important for clover establishment in pastures.

Schlussfolgerungen  Unter der Einschränkung, dass die alleinige Betrachtung der N-Wirkung nur einen Teil des N-Haushaltes ausmacht (z.B. Einbau von N in den Humuskörper), können aus den vorliegenden Ergebnissen folgende Schlussfolgerungen gezogen werden:  • Bei der aeroben Rotte bzw. Kompostierung von Mist wurden im Vergleich zur anaeroben Lagerung von Mist grössere N-Verluste gemessen, d.h. es wurde bei diesen Verfahren folglich weniger Stickstoff auf die Parzellen ausgebracht.  • Bei der Anwendung auf dem Feld erzielten Rottemist und Mistkompost im Vergleich zu Stapelmist jedoch eine bessere N-Wirkung.

Der folgende Artikel geht der Frage nach, ob sich in Bayern die bodenbedingte Ertragsfähigkeit von konventionell und ökologisch bewirtschafteten Flächen unterscheidet. Dazu wurden bayernweit verfügbare Datengrundlagen der landwirtschaftlichen Nutzung und der Wertzahlen der Bodenschätzung ausgewertet. Die Analyse ergab, dass bei Ackerflächen die Bodenzahlen von Ökoflächen geringfügig niedriger (51,4 / 52,2), bei Grünland die Grünlandgrundzahlen dagegen höher (48,1 / 44,5) sind. Gemittelt über Acker und Grünland besteht kein Unterschied (49,7 / 49,8) zwischen den beiden Bewirtschaftungssystemen.

In ökologischen Betrieben auf ertragsschwachen Standorten (z.B. sandige Böden, trockenes Klima) ist der Umfang des Tierbestandes häufig dadurch begrenzt, dass unter diesen Standortbedingungen nur eine limitierte Menge Futter erzeugt werden kann. Oft wirtschaften solche Betriebe vollständig viehlos. Die positiven Wirkungen von Stallmist sind somit nur bedingt oder überhaupt nicht nutzbar. Pflanzliche organische Dünger, wie z.B. Leguminosen-Blattmasse oder Körnerleguminosen-Schrote, könnten hier eine Alternative sein, wobei deren Effekte auf Ertrag und Qualität der Pflanzen sowie auf die Humusentwicklung der Böden im Vergleich zu Stallmist genau geprüft werden sollten.  Dies war die Zielsetzung unseres Projektes. Am Beispiel von Ackerbohnenschrot wurde in...

Jordlevende sopp vokser som lange trådformede strukturer kalt hyfer. Når flere hyfer vokser sammen dannes et hvitaktig mycel som vi kan se med det blotte øye. Sopp har ikke klorofyll og må derfor skaffe seg næring på annet vis. Det gjør de ved å hente næring fra organisk materiale  i jorda, fra å bryte ned ferske planterester på overflaten og/eller ved å leve i samliv (symbiose)med levende planterøtter (bildet. Selv om man kan se store og små sopper på overflaten, er det alltid slik at mesteparten av soppen finnes under jordoverflaten.

Clay dispersibility and soil friability – testing the soil clay-to-carbon saturation concept
Provedor de dados: 21
Autores: Schjønning, P.; de Jonge, L.W.; Munkholm, L.J.; Moldrup, P.; Christensen, B.T.; Olesen, J.E.
Soil organic carbon (OC) influences clay dispersibility, which affects soil tilth conditions and the risk of vertical migration of clay colloids. No universal lower threshold of OC has been identified for satisfactory stabilization of soil structure. We tested the concept of  clay saturation with OC as a predictor of clay dispersibility and soil friability. Soil was sampled three years in a field varying in clay content (~100 to ~220 g kg-1 soil) and grown with different crop rotations. Clay dispersibility was measured after end-over-end shaking of field-moist soil and 1-2 mm sized aggregates either air-dried or rewetted to -100 hPa matric potential. Tensile strength of 1-2, 2-4, 4-8 and 8-16 mm air-dried aggregates was calculated from their compressive...

Soil quality comparison among organically and conventionally managed citrus orchards in Eastern Sicily (Italy)
Provedor de dados: 21
Autores: Canali, Stefano; di Bartolomeo, Emanuela; Torrisi, Biagio.
The aim of this work was to compare soil fertility status of conventional and organic managed citrus orchards, using specific soil system descriptors.   The research was carried out in a Mediterranean environment (Sicily region, Southern Italy), on Navelina and Tarocco orange orchards. Soil characteristics were analysed in 54 farms under both organic and conventional management. Farms were selected to obtain similar pairs (27) in the same environmental conditions. For each soil, total organic carbon, total nitrogen, mineral NO3-N and NH4-N were determined. In addition, in order to evaluate biological fertility status of soils, carbon mineralisation and nitrogen mineralisation in anaerobic conditions were studied. Soils humic fraction was at least...

Soil biological quality in short- and long-term field trials with conventional and organic fertility input types
Provedor de dados: 21
Autores: Fließbach, Andreas; Schmidt, Christoph; Bruns, Christian; Palmer, Mike; Nietlispach, Bruno; Leifert, Carlo; Tamm, Lucius.
Soils of the DOK trial and three other field trials with manure input were analysed for effects on soil biology. While long-term effects indicate a new steady state at the DOK trial site, differences at the other field trials suggest that fresh manure at the Bonn trial and chicken manure at the UK sites are at least temporarily advantageous, probably due to their relatively fast mineralization.

Soil microbial communities and activities under intensive organic and conventional vegetable farming in West Java, Indonesia
Provedor de dados: 21
Autores: Moeskops, Bram; -, Sukristiyonubowo; Buchan, David; Sleutel, Steven; Herawaty, Lenita; Husen, Edi; Saraswati, Rasti; Setyorini, Diah; De Neve, Stefaan.
We compared the effect of organic and conventional farming practices on soil microbial dynamics in West Java, Indonesia. A secondary forest was included to obtain natural reference values. On the organic farms, soil fertility is maintained mainly with composted organic matter in contrast to conventional farmers who combine fresh manure and chemical fertilizers, and typically apply large amounts of pesticides. Parameters measured were dehydrogenase, β-glucosidase, acid phosphomonoesterase and β-glucosaminidase activity, microbial biomass C (MBC) and microbial community composition by phospholipid fatty acid analysis. A strong negative impact of intensive chemical fertilizer and pesticide use on soil enzyme activities was demonstrated. Dehydrogenase and...

Soil structure dynamics: Effects of management and water content
Provedor de dados: 21
Autores: Munkholm, Lars J.; Schjønning, Per; Elmholt, Susanne.
A review is given of the last 5 years research on soil structure dynamics carried out at the Danish Institute of Agricultural Sciences. The studies were initiated as part of a large programme focussing on the development of organic farming in Denmark. In organic farming a healthy and living soil is highly valued. Holistic thinking is also a key element in the organic farming concept. In order to integrate a holistic thinking in our soil structure research a multidisciplinary approach was adapted that integrated soil physics, chemistry and microbiology. In addition, soil structure was studied at different levels from undisturbed “whole soil” in the field to specialized reductionistic studies using size separated or remoulded soil in the laboratory. In a...

Soil Fertility in Organic Farming in the First Years After Transition
Provedor de dados: 21
Autores: Cuvardic, Assoc. Prof. Maja; Seremesic, M.Sc. Srdjan; Novakovic, Dipl. ing. Nenad.
In this paper soil fertility indices were compared on four organic farms with neighbouring fields under conventional farming. The organic farms were in the first years after organic transition. Results indicate that there were significant differences between farming systems in nitrate nitrogen (NO3-N), available phosphorus (AL-P2O5) and potassium (AL-K2O). However, there were no significant differences in organic matter (OM) and total N contents between organic and conventional systems, although higher, but not significantly higher, soil fertility indices were found in conventional farming. There were no significant differences between organic and conventional systems in C/N ratio, although wider C/N ratio was found on organic fields with low fertility...

Soil bacterial and fungal communities along a soil chronosequence assessed by fatty acid profiling
Provedor de dados: 21
Autores: Welc, Monika; Bünemann, Else K.; Fließbach, Andreas; Frossard, Emmanuel; Jansa, Jan.
Microbial communities are important components of terrestrial ecosystems. The importance of their diversity and functions for natural systems is well recognized. However, a better understanding of successional changes of microbial communities over long time scales is still required. In this work, the size and composition of microbial communities in soils of a deglaciation chronosequence at the Damma glacier forefield were studied by fatty acid profiling. Soil fatty acid concentrations clearly increased with soil age. The abundances of arbuscular mycorrhizal fungi (AMF), bacteria and other soil fungi, however, were more affected by abiotic soil parameters like carbon content and pH than by soil age. Analysis of ratios of the different microbial groups (AMF,...

Greenhouse gas fluxes from agricultural soils under organic and non-organic management - A global meta-analysis
Provedor de dados: 21
Autores: Skinner, Colin; Gattinger, Andreas; Müller, Adrian; Mäder, Paul; Fließbach, Andreas; Stolze, Matthias; Ruser, Reiner; Niggli, Urs.
It is anticipated that organic farming systems provide benefits concerning soil conservation and climate protection. A literature search on measured soil-derived greenhouse gas (GHG) (nitrous oxide and methane) fluxes under organic and non-organic management from farming system comparisons was conducted and followed by a meta-analysis. Up to date only 19 studies based on field measurements could be retrieved. Based on 12 studies that cover annual measurements, it appeared with a high significance that area-scaled nitrous oxide emissions from organically managed soils are 492 ± 160 kg CO2 eq. ha− 1 a− 1 lower than from non-organically managed soils. For arable soils the difference amounts to 497 ± 162 kg CO2 eq. ha− 1 a− 1. However, yield-scaled nitrous...

Drivers of organic carbon allocation in a temperate slope-floodplain catena under agricultural use
Provedor de dados: 21
Autores: Mayer, Stefanie; Schwindt, Daniel; Steffens, Markus; Völkel, Jörg; Kögel-Knabner, Ingrid.
The distribution of soil organic carbon (OC) in the landscape shows high variability between landform positions.  Soils in depositional sites are characterized by a highly diverse vertical structure and can contain significant amounts of OC over the whole soil profile. However, anthropogenic modifications of the landscape such as land use and artificial drainage can significantly alter the OC balance in a catchment. Here, we analyse the spatial distribution of OC stocks along an agriculturally used catena in a catchment, tributary to the Danube River in the Bavarian Forest in Southern Germany. The combination of geomorphic aspects with highly detailed soil data based on 16 soil profiles along a catena allowed us to closely examine the relationship between...

Tillage effects on weed communities in an organic winter wheat-sunflower-spelt cropping sequence
Provedor de dados: 21
Autores: Sans, F. X.; Berner, A.; Armengot, L.; Mäder, P.
Conservation tillage could provide environmental benefits to organic farming. However, potential weed problems often tend to discourage farmers from adopting it. The effects of tillage (reduced vs. conventional), fertilisation (slurry vs. manure compost) and the application of biodynamic preparations (with and without) on crop yield and on weed cover, diversity and biological attributes were investigated in a cropping sequence of wheat, sunflower and spelt. Total weed cover and perennial cover in reduced tillage treatments were two to three times greater than in conventional treatments. Monocotyledon cover in reduced tillage was three times that in conventional tillage in spelt, whereas the dicotyledon Stellaria media dominated in sunflower. Weed diversity...

Provedor de dados: 21
Autores: Thomsen, I.K.; Schjønning, P.; Jensen, B.; Kristensen, K.; Christensen, B.T.
To evaluate the effect of soil texture and soil water content on decomposition of organic carbon (OC), turnover of partially stabilized 14C-labelled ryegrass residues was studied at four matric potentials in twelve differently textured soils of similar origin and cropping history. Six soils were from a naturally occurring clay gradient and had 11, 16, 21, 31, 37 and 45% clay (termed NA1 to NA6). Three clay-amended soils (CL2, CL4, CL6) and three silt-amended soils (SI2, SI4, SI6) were prepared by adding clay or silt sized organomineral complexes extracted from the NA2 soil to a portion of the NA1 soil. After 14C-labelled ryegrass had decomposed for eight months under field-like conditions, soil cores were sampled, adjusted to four matric potentials (-30,...

Soil organic matter and biological soil quality indicators after 21 years of organic and conventional farming
Provedor de dados: 21
Autores: Fliessbach, Andreas; Oberholzer, Hans-Rudolf; Gunst, Lucie; Paul, Mäder.
Organic farming systems often comprise crops and livestock, recycle farmyard manure for fertilization, and preventive or biocontrol measures are used for plant protection. We determined indicators for soil quality changes in the DOK long-term comparison trial that was initiated in 1978. This replicated field trial comprises organic and integrated (conventional) farming systems that are typical for Swiss agriculture. Livestock based bio-organic (BIOORG), bio-dynamic (BIODYN) and integrated farming systems (CONFYM) were compared at reduced and normal fertilization intensity (0.7 and 1.4 livestock units, LU) in a 7 year crop rotation. A stockless integrated system is fertilized with mineral fertilizers exclusively (CONMIN) and one control treatment remained...

Autores: Costantini, E.A.C.; Agnelli, A.E.; Fabiani, A.; Gagnarli, E.; Mocali, S.; Priori, S.; Simoni, S.; Valboa, G.
Deep earthwork activities carried out before vineyard plantation can severely affect soil profile properties.  As a result, soil features in the root environment are often much more similar to those of the underlying  substratum than those of the original profile. The time needed to recover the original soil functions is ecologically  relevant and may strongly affect vine phenology and grape yield, particularly under organic viticulture.  The general aim of this work was to investigate soil resilience after vineyard pre-planting earthworks. In  particular, an old and a new vineyard, established on the same soil type, were compared over a 5-year period for  soil chemical, physical, micro- and mesobiological properties.  The investigated vineyards (Vitis...

Conservation tillage (no-till and reduced tillage) brings many benefits with respect to soil fertility and energy use, but it also has drawbacks regarding the need for synthetic fertilizers and herbicides. To promote conversation tillage in organic farming systems, crop rotation, fertilization and weed control have to be optimized. In addition, crop varieties are needed with improved nutrient use efficiency (NUE) and high weed competitiveness or tolerance.

Reduced TILlage and Green MANures for sustainable ORGanic Cropping Systems
Provedor de dados: 21
Autores: TILMAN-ORG,.
No-Till (NT) and Reduced Tillage (RT) are conservation tillage practices with a high potential to restore or improve essential soil functions and mitigate climate change through carbon sequestration and reduced fuel use. While NT systems are widely used in conventional farming, these techniques are challenging to adapt to organic farming due to weed pressure and frequent nitrogen deficiency in early spring. A potential answer may be RT, such as shallow inversion ploughing, or non-inversion tillage. In TILMAN-ORG, the implementation of these practices in European organic farming systems was addressed by an interdisciplinary team of researchers from 11 European countries.

Autores: Krause, Hans-Martin; Hüppi, Roman; Leifeld, Jens; El-Hadidi, Mohamed; Harter, Johannes; Kappler, Andreas; Hartmann, Martin; Behrens, Sebastian; Mäder, Paul; Gattinger, Andreas.
N2O is a major greenhouse gas and the majority of anthropogenic N2O emissions originate from agriculturally managed soils. Therefore, developing N2O mitigation strategies is a key challenge for the agricultural sector and biochar soil treatment is one reported option. Biochar's capacity to increase soil pH and to foster activity of specialized N2O reducers has been proposed as possible mechanisms for N2O mitigation. An experiment was undertaken to investigate whether changes in the community composition of N2O reducers was observed under field conditions after biochar application. The study objective was to assess the abundance and taxonomic composition of the functional marker genes nosZ and nosZ –II across a vegetation period of Zea mays L. after biochar...

A comparison of soil and water properties in organic and conventional farming systems in England
Provedor de dados: 21
Autores: Hathaway-Jenkins, L. J.; Sakrabani, R; Pearce, Bruce; Whitmore, A. P; Godwin, R. J.
Organic farming and improvements to agricultural sustainability are often seen as synonymous. However, an extensive European review demonstrated that in practice this is not always true. This study aims to compare the status of soil and water properties between separate fields managed in either an organic or a conventional manner. Soil samples were collected from 16 pairs of farms, throughout England, with both arable and grass fields within each pair on similar soil type. Chemical (nutrients, pesticides, herbicides) and physical (aggregate stability, field capacity, shear strength, soil organic matter, infiltration rates) soil properties were measured in four main soil texture classes in organic and conventional fields. The physical soil properties varied...

Effects of an organic and a conventional cropping system on soil fertility
Provedor de dados: 21
Autores: Boldrini, Dr Arianna; Benincasa, Dr Paolo; Gigliotti, Prof Giovanni; Businelli, Prof Daniela; Guiducci, Prof Marcello.
An experiment was started in 1998 in Central Italy to evaluate changes in soil fertility and the risk of N loss in an organic (ORG) and a conventional low input (CONV) cropping system. At the end of a 6-year rotation, ORG caused a higher plant biomass incorporation into the soil and thus a higher soil soluble organic carbon. The N surplus in ORG was 32% higher than in CONV, while no differences were recorded on N content in the top soil, so that ORG implicated a higher N loss from that soil layer. In ORG we recorded a higher phosphatase activity but a lower available soil P (due to application of rock phosphate in sub-alkaline soil) and a lower exchangeable K.

Combined Application of Oil Cake and Rice Bran  Reduced the Number of Weeds and Increased  the Yield of Paddy Rice in a Pad Field    Incorporated with White Clover
Provedor de dados: 21
Autores: Sugimoto, Hideki; Takuya, Araki; Masahiro, Morokuma; Hossain, Shaikh Tanveer.
The combined application of oil cake and rice bran into the soil surface was found useful for weed control in our previous pot study. The present study was undertaken to evaluate the performance of white clover (Trifolium repens L.) while incorporated in the paddy field and effects of combined fertilizer on weed control and rice yield.  A plot was divided into two parts i.e. white clover incorporated and not incorporated. The nitrogen content of the incorporated white clover was 12.5 gm-2. Chemical fertilizer and combined fertilizer plots were compared with non-fertilizer conditions. The mixed ratio of combined fertilizer was oil cake 1.35 and rice bran 1.0. Combined fertilizer was applied to the soil surface, and chemical fertilizer was mixed in the soil....

Alsidig drift godt for jordens poresystem
Provedor de dados: 21
Autores: Schjønning, P.
I økologisk jordbrug anvendes alsidige sædskifter, efterafgrøder og/eller tildeling af husdyrgødning/halm/kompost. Alt dette er med til at fremme mængden af organisk stof i jorden, som normalt forventes at spille en stor rolle for strukturen og poresystemet (jordens hulrum). FØJO har gennemført en række undersøgelser for at afdække, hvor meget og hvordan man som landmand kan påvirke forholdene.  De langvarige forsøg med forskellig gødskning på Askov Forsøgsstation giver et godt grundlag for at vurdere effekten af organisk stof på jordens poresystem. Ca. 100 års forsøg uden tilførsel af nogen form for gødning har resulteret i et indhold af organisk stof i jorden på kun ca. 1% (svarende til et humusindhold på ca. 1,7%). Brug af mineralsk gødning (NPK) har...

Soil heath: a comparison between organically and conventionally managed arable soils in the netherlands
Provedor de dados: 21
Autores: van Diepeningen, Anne D.; Blok, Wim; Korthals, Gerhard W.; van Bruggen, Ariena H.C.
A comparative study of 13 organic and 13 neighboring conventional arable farming systems was conducted in the Netherlands to determine the effect of management practices on chemical and biological soil properties and soil health. Soils were analyzed using a polyphasic approach combining traditional soil analysis, culture-dependent and independent microbiological analyses, a nematode community analysis and an enquiry about different management practices among the farmers. Organic management resulted in significantly lower levels of both nitrate and total soluble nitrogen in the soil, higher numbers of bacteria of different trophic groups, as well as larger species richness in both bacteria and nematode communities and more resilience to a drying-rewetting...

Einfluss von Bewirtschaftungsmaßnahmen auf die Struktur und Funktion der Bodenmikroflora
Provedor de dados: 21
Autores: Schloter, Michael; Cania, Barbara; Schulz, Stefanie.
Im ökologischen Landbau gilt es unter umweltschonender Bewirtschaftung trotzdem hohe Erträge zu erzielen. Bisher wurde dies durch konventionelle Pflügung realisiert, diese Maßnahme zerstört aber die Bodenstruktur und damit den Lebensraum wichtiger Organismengruppen. Daher ist es wünschenswert die im konventionellen Landbau schon übliche reduzierte Bodenbearbeitung auch im  ökologischen Landbau zu etablieren. Im Rahmen dieses Projektes wurde daher untersucht wie sich die reduzierte Bodenbearbeitung auf das Mikrobiom auswirkt. Da Pflügen insbesondere die Bodenstruktur zerstört, lag der besondere Fokus auf dem bakteriellen Potential strukturbildende Substanzen wie Exo-(EPS) und Lipopolysaccharide (LPS) zu produzieren. Dazu wurden vier Standorte mit...

The changing needs with time for mineral nutrition of organic stone fruit orchard under Mediterranean conditions
Provedor de dados: 21
Autores: Raviv, Michael; Iviani, Ido; Laor, Yael.
Mediterranean climatic conditions for stone fruit production are good but soil fertility is low, mainly due to low (&lt; 2.0%) soil organic matter (OM). Consequently, conventional growers apply high fertiliser rates (typically ~350 Kg N ha-1 yr-1). Our main objectives were to compare the effects of 2 modes of nitrogen nutrition, suitable for organically certified orchard vs a conventional control on tree development, yield, and some soil chemical, physical and biological properties. The orchard is located on a Grumosol soil, in the Jezreel Valley, Israel and is treated organically in terms of plant protection and weed control. The orchard was planted to peach, plums and nectarines in 1998, all grafted onto rootstock CV. 677. The tested treatments were: A....

Provedor de dados: 21
Autores: Landi, S.; Priori, S.; Simoni, S.; Costantini, E.A.C.
In viticoltura, la non corretta preparazione del terreno prima dell’impianto comporta la formazione di aree degradate caratterizzate da scarsa produzione e la presenza di piante più suscettibili a fitoparassiti e fitopatologie. Le cause del malfunzionamento del suolo possono essere imputate alla riduzione del contributo della fauna del suolo e dei servizi ecosistemici a essa legati come il ciclo dei nutrienti, l’impoverimento nel contenuto di sostanza organica, alterazione del pH, il deficit idrico e la compattazione del suolo.

Omlegging til økologisk drift ved Tingvoll gard startet etter at Norsk senter for økologisk landbruk (NORSØK) i 1987 inngikk leieavtale om garden. Fram til 1996 var gardsdrifta sterkt integrert i NORSØK sin virksomhet, med mål om å drive ei allsidig gardsdrift som kunne synliggjøre idégrunnlaget i økologisk landbruk. Siden 1996 har gardsdrifta vært organisert som et familiebruk, drevet av forpakter. Forpakterfamilien er avhengig av inntektene fra gardsdrifta, og de er forpliktet til å drive i tråd med reglene for økologisk produksjon. Av økonomiske, interesse- og arbeidsmessige årsaker har gardbrukerne valgt å konsentrere drifta om melkeproduksjon. Fra 2006 inngikk forpakterne samdrift med en nabogard, noe som ga økt melkekvote og grunnlag for økt...

Wirkung von Biochar und organischen Düngern auf Pflanzenwachstum und Bodeneigenschaften
Provedor de dados: 21
Autores: Reents, Hans Jürgen; Levin, Kain.
The effects of Biochar and combinations with organic manures on plant biomass and soil properties were tested in a lab experiment with two different soils. Highest applications (10%) of Biochar alone implicated a plant growth decrease while the manure combinations increased biomass, especially in the Luvisol. This positive reaction was not detected in the Regosol during the experiment. Increasing rates of the different amendments decreased soil bulk density, especially in the Luvisol. Manures increased soil respiration, Biochar had nearly no effect. In order to improve soil fertility, combining Biochar with organic N-fertiliser is recommended.

A PRACTICE APPLICABLE MODEL FOR THE ASSESSMENT OF MANAGEMENT IMPACT ON ORGANIC MATTER IN ARABLE SOILS
Provedor de dados: 21
Autores: Brock, Christopher; Leithold, Günter.
We present the HU-MOD-2 model for the assessment of management impact on organic matter levels in arable soils. The model aims at optimal applicability as a management support tool in framing practice and therefore requires only easily available input data. In validation, the tool proved to be capable of giving a rough estimate on soil organic matter changes in arable soils. Taking into account the low demand for input data, the modeling error seems tolerable for a practice applicable decision support tool.

Biochar as a Soil Amendment: A Review of the Environmental Implications
Provedor de dados: 21
Autores: Woolf, Dominic.
The  term  'biochar'   refers  to black carbon  formed by  the pyrolysis of  biomass  i.e.  by heating biomass in an oxygen-free or low oxygen environment such that it does not (or only partially) combusts.   Traditional charcoal is one example of biochar produced from wood.  The term 'biochar' is much broader than this however, encompassing black carbon produced from any biomass feedstock.   The use of biochar as a soil additive has been proposed as a means  to simultaneously mitigate anthropogenic climate change whilst improving agricultural soil fertility.   This paper provides a review of what is known about both of these claims and also about the wider environmental implications of the adoption of this process.  The intention of this review is not...

It is supposed that organic farming reduces soil water erosion due to a long soil  coverage and soil aggregation by roots and organic manure. In a long term field trial  which is focused on the effect of legume management in different crop rotations soil  aggregation in the top layer of 0-5 cm was tested and correlated with some other soil  properties and indicators of carbon balances. There are differences in aggregate  stability between the crop rotations. The incorporated plant material (roots, stubble  residues, green manure) has the best effect on the stability of soil aggregates.

Den teknologiske udvikling i landbruget igennem de seneste årtier har betydet, at der bruges mindre og mindre tid med at dyrke hver enkelt ha, og tiden tilbringes i et komfortabelt førerhus flere meter over jorden. Spørgsmålet er om vi er ved at miste fornemmelsen for jord. Hvad gør jorden mere bekvem? Ja mange vil sikkert svare at husdyrgødning, halmnedmuldning, kompost etc. gør jorden mere bekvem. Andre vil sikkert svare at strukturskader gør jorden ubekvem. I et forskningsprojekt ved Danmarks JordbrugsForskning er der blevet sat tal på effekten af langvarig tilførsel af husdyrgødning og af pakning og intensiv jordbearbejdning.

Direct and indirect effects of urban gardening on aboveground and belowground diversity influencing soil multifunctionality
Provedor de dados: 21

Urban gardens are popular green spaces that have the potential to provide essential ecosystem services, support human well-being, and at the same time foster biodiversity in cities. We investigated the impact of gardening activities on five soil functions and the relationship between plant (600 spp.) and soil fauna (earthworms: 18 spp., springtails: 39 spp.) in 85 urban gardens (170 sites) across the city of Zurich (Switzerland). Our results suggest that high plant diversity in gardens had a positive effect on soil fauna and soil multifunctionality, and that garden management intensity decreased plant diversity. Indices of biological activity in soil, such as organic and microbial carbon and bacterial abundance, showed a direct positive effect on soil...

Driftsformen har begrænset effekt på jordens evne til at holde på vandet
Provedor de dados: 21
Autores: Schjønning, P.; Iversen, B.V.; Jacobsen, O.H.
De mængder af organisk stof, man påvirker med almindelig landbrugsdrift, har ikke nævneværdig indflydelse på jordens vandholdende evne. Anvendelse af husdyrgødning i stedet for mineralsk gødning kan heller ikke forventes at påvirke jordens ledningsevne for vand i pløjelaget. Et højt næringsstofniveau giver – formodentlig pga bedre rodvækst – flere store porer og bedre ledningsevne for vand i jordlaget under pløjedybde. Effekten er uafhængig af, om næringsstofferne er tildelt som husdyrgødning eller som mineralsk gødning.

Autores: Berntsen, J.; Petersen, B.M.; Kristensen, I.S.; Olesen, J.E.
Med udgangspunkt i regnskabsdata fra Fødevareøkonomisk Institut (FØI) og data fra Centrale Registre (CR) blev importen af kvælstof (N) i gødning til marken til konventionelle og økologiske planteavlere  estimeret til hhv. 129 og 51 kg N ha-1 år-1. Desuden blev der med udgangspunkt i den aktuelle afgrødefordeling opstillet et generelt sædskifte for hver af de to systemer. Det opstillede sædskifte for den økologiske planteavl havde en høj andel af vårsæd og desuden 20% kløvergræs, mens den konventionelle planteavl var domineret af kornafgrøder primært i form af vintersæd.   Med baggrund i disse model-sædskifter blev N-balancen på markniveau beregnet ved anvendelse af FASSET modellen. Dette inkluderede også N-udvaskning og ændring i jordens N-pulje. Alle...

Gardens have effects on the local ecology as well as on the wellbeing of the gardener, but few studies have attempted to study gardens using both ecological and social outcome variables. The aim of this exploratory study is to address this research gap by identifying the characteristics of gardens and the management practices of gardeners that enhance the outcomes of gardening, which we separate into three dimensions: human wellbeing, biodiversity, and soil quality. Data were collected from 18 gardens in Zurich, Switzerland and a typology of gardeners was dentified,which included ‘conservationist’, ‘functional’, ‘minimumeffort’,  ‘child-friendly’, and ‘aesthetic’ gardeners.

Does early spring grazing stimulate spring grass production?
Provedor de dados: 21
Autores: Eekeren, N. van; Rietberg, P.I.; Iepema, G; Wit, J. de.
Early spring grazing may stimulate grass growth in spring by increasing grass root exudation, which enhances mineralization. The objective of this study was to investigate the net effect of early spring grazing on spring grass production. Therefore, we conducted two field experiments on production grasslands. Simulated early spring grazing negatively affected the yield of the first cut: compared to ungrazed plots on sandy soil an a tendency on clay soil, dry matter yield of early-plots was reduced by 20% (sand, P=0.009) and 12% (clay, 0.062), respectively. These differences were partly compensated in later cuts. Despite the negative effect on grass yield of the first cut, early grazing positively affected the crude protein (CP) content of the grass in the...

Intensify pastures for livestock production: vermicompost use, an agro-ecological practice
Provedor de dados: 21
Autores: Boval, Maryline; Faverial, J.; Mulciba, P.; Loranger-Merciris, G.L.M.; Sierra , J.
The intensification of animal production at pasture is essential to meet the growing demand for animal products but also for other functions, the maintenance of areas, livelihoods and well-being of populations. This intensification must also take into account the reduction of agricultural land, promote positive interactions with the environment and biodiversity, while ensuring the supply of populations. The use of vermicompost involving the action of earthworms is an example of agro-ecological practices, to participate in the intensification of grassland and which has been studied in the context of a call to project, AGRIBIO3. Besides the fact that this practice makes it possible to achieve a proper recycling and recovery of various manures, it improves...

Sheepdrove Organic Farm Soils Programme Report 2003 Interim Report
Provedor de dados: 21
Autores: Philipps, Lois.
Sheepdrove Organic Farm wishes to maintain or improve soil fertility (where appropriate) in accordance with organic principles and to gain a greater understanding of the biological activity with the soil ecosystems of the farm. In order to monitor changes in soil fertility a monitoring programme has been established to record all available past soils data and implement an ongoing programme that meets the agronomic needs of the farming enterprises and contributes to the ‘Sheepdrove Story’.  From the limited data collected to date there is evidence that organic matter levels are higher than would be expected on these soil types and that past management has maintained major nutrient status at ‘conventional’ levels.

Biotic and abiotic binding and bonding mechanisms in soils with long-term differences in management
Provedor de dados: 21
Autores: Elmholt, Susanne; Munkholm, Lars J.; Debosz, Kasia; Schjønning, Per.
During the last decades Denmark has experienced a growing interest in low-input farming systems like organic farming. These systems rely on a high soil fertility to maintain nutrient availability and plant health. Soil aggregation contributes to this fertility, because it is crucial to soil porosity, aeration and infiltration of water. This paper reports a study of two pairs of differently managed, neighboring fields. The aim was to elucidate long-term effects of the different farming systems on physical and biological variables with influence on bonding and binding mechanisms of soil aggregation. Each pair consists of an organically grown dairy farm soil, based on a forage crop rotation system, including grass (Org-FCS(G)) and a conventionally managed...

Barley undersown with red clover in organic and conventional systems: nitrogen aftereffect on legume growth
Provedor de dados: 21
Autores: Alaru, Marika; Talgre, Liina; Luik, Anne; Tein, Berit; Eremeev, Viacheslav; Loit, Evelin.
Nitrogen (N) deficiency is a major problem in organic and low-input farming systems. Growing spring cereals with  undersown legumes has a positive effect on soil fertility, enriching it with nitrogen, through symbiosis of legumes  with nodule bacteria. Two hypotheses were tested: 1) undersowing of red clover increases the protein content of  barley grains and 2) mineral N has negative aftereffect on growth of legume plants. The aim of this study was to  investigate the effect of organic (cattle manure, off-season cover crop) and mineral N in organic and conventional  farming systems on (i) barley (Hordeum vulgare L.) grain yield and quality, (ii) biomass yield formation of  undersown red clover (Trifolium pratense L.) and (iii) the aftereffect of mineral...

Worldwide interest in soil quality evaluation has increased rapidly throughout the past decade, prompting us to evaluate the long-term impact of four cropping systems on several biological, chemical and physical determinants of soil quality. We hypothesized that after 17 years several of the determinants would show significant differences between conventional cereal and low input/organic rotations. Four crop rotations were imposed on a silt soil from 1982 through 1999. Rotation A was a conventionally managed cereal rotation that received 100% of the recommended mineral fertilizer each year. Rotation B was also managed conventionally from 1982 until 1993, although it received only 50% of the recommended mineral fertilizer. From 1994 through 1999, rotation B...

Effects of Compost on Soil Fertility Parameters in Short-, Mid- and Long-Term Field Experiments
Provedor de dados: 21
Autores: Fuchs, J. G.; Fliessbach, A.; Mäder, Paul; Weibel, F.P.; Tamm, L.; Mayer, J.; Schleiss, K.
To evaluate the influence of compost on soil fertility and plant growth, several medium term and long term field experiments with composts were conducted in different crops.  In two maize experiments, one in a sandy and one in a loamy soil, the influence of different composts and digestates on soil parameters and plant growth were investigated. All products increased pH of the soil and improved the biological soil activity (e.g., enzymatic activities). Immature compost immobilized nitrogen and reduced plant growth. Organic nitrogen fertilizer added during cultivation, could compensate the growth depression.  A full factorial experiment in a 2-years-old organic apple orchard was conducted from 2001-2007. The factors tested in all 9 possible combinations...

For the assessment of soil erosion many models have been developed. Most of these  don’t consider specific effects of organic agriculture (OA). That might result in wrong  calculations of soil losses. This paper describes how the widespread model ABAG  could be adopted to OA. But some effects can not be included easily. This seems to  be possible when using the model RUSLE2, which is compatible to ABAG. But at least  the carry-over effect of leys and the influence of pesticides need further research.

Autores: Brock, Christopher; Blumenstein, Benjamin; Dannehl, Theresa; Möller, Detlev.
An adequate supply of organic matter to arable soils is essential for the maintenance of soil productivity. Still, management implications can cause a trade-off with  economics, as measures for soil organic matter management may not directly induce ecosystem services that increase the profitability of the system. This is especially true  with regard to stockless organic farming systems, where well-proven measures, as the integration of fodder legumes in crop rotations, may not seem attractive with regard to  the revenue. In this article we evaluate strategies for soil organic matter management in stockless organic farming systems based on scenarios for different soil-climate  conditions in Germany to deal with this challenge. Several options to make use of...

Sampling and analysis or visual examination of soil to assess its status and use potential is widely practiced from plot to national scales. However, the choice of relevant soil attributes and interpretation of measurements are not straightforward, because of the complexity and site-specificity of soils, legacy effects of previous land use, and trade-offs between ecosystem services. Here we review soil quality and related concepts, in terms of definition, assessment approaches, and indicator selection and interpretation. We identify the most frequently used soil quality indicators under agricultural land use. We find that explicit evaluation of soil quality with respect to specific soil threats, soil functions and ecosystem services has rarely been...

PLANT UPTAKE OF SOLUBLE ORGANIC MOLECULES AS N SOURCE
Provedor de dados: 21
Autores: Reeve, Jennifer; Smith, Jeffrey L.; Carpenter-Boggs, Lynne; Reganold, John P.
Plants take up nitrogen principally in the form of nitrate and ammonium; however, evidence is growing that they can also utilize organic nitrogen in the form of amino acids and soluble proteins. We are conducting research to determine whether wheat grown in soil fertilized with organic N utilizes more organic N directly than wheat grown with inorganic N.  We are also testing for differences in uptake of amino acids between pre 1930s varieties and modern varieties of wheat to determine whether this trait has been selected for or against by breeding under high inorganic N input.  Preliminary results show both wheat varieties Arco and Madsen take up 14C labeled glycine under sterile conditions.  Further experiments to determine the role of microbial...

Multispectral remote sensing in participatory on-farm variety trials
Provedor de dados: 21
Autores: Drexler, Dora; Kovács, Tina; Varga, Korinna.
On the one hand, through the analysis of remote sensing images, it was possible to determine weed infestation, field heterogeneity and NDVI values/pixel (app. 1 cm per pixel). In some cases, we even discovered previously unknown underground field objects (e.g. a drainage system from the 70s).   On the other hand, NDVI data did not correlate with traditional sampling results (SPAD values and yield estimations), probably because the multicopter covered 100 % of the large plot area, while sampling only provided data from specific points (50 SPAD points/plot and three yield sampling quadrats/plot). We can thus assume that for large plot variety trials, remote sensing can give substantially more precise results than traditional sampling methods. Further tests...

Several studies indicate that cover crops can be used to enhance agricultural sustainability as they provide numerous ecological services in agro-ecosystems. They protect soil against erosion and nutrient losses and compete weeds. Moreover, legume species fix nitrogen (N) from the atmosphere and contribute to next crop nutrition. Hence, cover crops complement the ecological aims of organic agriculture. We investigated the impact of cover crops in different cropping systems (organic and conventional) and soil tillage intensities (plough, reduced and no-tillage) in various field experiments. Moreover, results from an experimental network, which has investigated the behavior of more than 11 cover crops, is included. Results show that  the effects of cover...

Effects of anaerobically digested manure on soil fertility - establishment of a long-term study under Norwegian conditions
Provedor de dados: 21
The project SOILEFFECTS will identify potential risks and benefits for soil fertility when animal manure is anaerobically digested for biogas production.In systems with preferably closed cycles of nutrients and organic matter,such as organic farms, soil fertility cannot be easily maintained by purchased nutrients, and manure quality is crucial. Anaerobic digestion of animal  manure for biogas utilization decreases the amount of organic carbon (C)applied to the soil, especially easily degradable C fractions. This may affect soil biology, for instance because earthworms and microorganisms compete  about this C as a source of feed. Less earthworm activity would impact negatively soil structure and fertility. Less C application to the soil may also more...

Animal manures regarded as wastes could be channeled towards improving the fertility of the soil and crop production. A field experiment was conducted at the Federal University of Agriculture, Abeokuta Nigeria in 2013 to evaluate the effect of animal manures on yield and chemical properties of soil grown with Solanum macrocarpon. Treatments used were: goat manure at 10, 20 and 30t/ha (GM 10, GM 20 and GM 30 respectively), poultry manure at 10, 20 and 30t/ha (PM 10, PM 20 and PM 30 respectively), cow dung at 10, 20, 30t/ha (CD 10, CD 20 and CD 30 respectively) and control.

Autores: Deru, Joachim; Schilder, Henk; Schoot, Jan Rinze, van der; Eekeren, N. van.
Although grasses have dense rooting systems, nutrient uptake and productivity can be increased, and N-leaching reduced, if rooting is further improved. The variation in root mass of 16 varieties of Lolium perenne was studied under field conditions in two experiments on sandy soil in The Netherlands.The chosen varieties differed in genetic and aboveground characteristics such as ploidy, productivity and grass cover. Root dry matter (RDM) was measured in the 0–8, 8–16 and 16–24 cm soil layers. In summary, we found that RDM of perennial ryegrass differed significantly between arieties under field conditions. These differences were not linked to grass yield, which indicates that it is possible to select perennial ryegrass varieties that combine high...

Indicators for the Evaluation of Soil Organic Matter and their Application in Organic and Conventional Farming Systems
Provedor de dados: 21
Autores: Hoyer, Uta; Reents, Hans-Jürgen; Hülsbergen, Kurt-Jürgen.
In view of the problems caused by soil degradation, it becomes ever more important to estimate the influence of different management systems on soil organic matter (SOM). In the past, a number of indicators characterizing SOM have been elaborated, which, however, do not allow to draw conclusions on separate management measures or even future development tendencies. A promising approach might be humus balancing, which quantifies and evaluates the humus supply of soils on the basis of crop rotation and fertilization. Comparative studies on adjacent arable sites under both organic and conventional management in different climatic regions of Germany have revealed that the indicator soil organic carbon (SOC) depends mainly on the site conditions, whereas...

Effects of plant residues on crop performance, N mineralisation and microbial activity including field CO2 and N2O fluxes in unfertilised crop rotations
Provedor de dados: 21
Autores: Vinther, F.P.; Hansen, E.M.; Olesen, J.E.
The impacts of crop rotation and input of organic matter in the form of green manure crops, straw residues and incorporation of catch crops on crop yield, nitrogen uptake, microbial biomass and activity was studied in unfertilised crop rotations differing in input of plant residues, i.e. high-input rotations with a grass-clover crop and catch crops included and low-input cereal rotations without catch crops. The parameters studied included substrate induced respiration (SIR), hydrolysis of fluorescein diacetate (FDA), arylsulfatase activity (ASA), N mineralisation, N2O emission, and soil respiration. These parameters were measured in bare soil plots, to estimate the effects of previous years crops and input of plant residues. In neighbouring plots crop...

Autores: Simoni, S.; Gagnarli, E.; Goggioli, D.; Guidi, S.; Tarchi, F.; D'Avino, L.; Giffard, B.
Quantitative and qualitative analyses among the soil microarthropods can be used in biomonitoring as tools in multi-disciplinary approach to characterize soil quality. Three groups of microarthropods - Collembola and Oribatida as detrivores and Gamasina as predators - were selected to evaluate the impact of different management treatments adopted to recover degraded soil in organic. Differences in arthropod populations between French and Italian sites were registered. In Italy, after two years of recovering treatments, an increase of the abundances of all groups, particularly detritivores in degraded plots, was observed. The population of gamasids increased, in all sites, only in non degraded plots. Soil invertebrates of similar trophic groups, like...

Naar een betere benutting van bodemfosfor
Provedor de dados: 21
Autores: Rietberg, P.I.; Timmermans, B.G.H.
In de Nederlandse landbouw wordt de aanvoer van fosfor (P) via mest en compost steeds verder aan banden gelegd. De uitdaging voor telers is om bij beperkte fosforaanvoer toch een goede opbrengst te realiseren. Dit artikel beschrijft onderzoek op twee biologische bedrijven die telen bij lage fosfaataanvoer en lage bodemfosforgehalten. Het gaat in op de vraag of er op deze bedrijven fosforgebrek of fosforlimitatie wordt ervaren en beschrijft experimentele resultaten. Vervolgens wordt kort ingegaan op de mogelijke bijdrage van vlinderbloemigen en van mineralisatie van fosfor uit organische stof aan de fosforvoorziening van het gewas.

Soil sustainability in organic agricultural production
Provedor de dados: 21
Autores: May-Roberts, S; Robertson, J; Killham, K; Paton, G.
Traditionally, the assessment of soil sustainability and the potential impact of cultivation are based upon the application of chemical procedures. In the absence of a biological context, these measurements offer little in understanding longterm changes in soil husbandry. Detailed microcosm investigations were applied as a predictive tool for management change. The microcosms were designed with homogenised soils treated with organic amendments. Key soil functional relationships were quantified using stable isotope techniques, biochemical measurements and traditional approaches.

One of the objectives of the TILMAN-ORG Project is to improve weed management under conservation agriculture (reduced tillage and/or cover crops) in organic arable systems. The shift from ploughing to conservation agriculture should not only maintain crop yield but possibly improve weed community diversity. This paper summarises the results on (1) weed abundance, (2) weed diversity and (3) crop yield obtained in the first year of the project (2012) in 13 trials scattered across Europe.

Effects of animal manure application on springtails (Collembola) in perennial ley
Provedor de dados: 21
Autores: Pommeresche, Reidun; Løes, Anne-Kristin; Torp, Torfinn.
The density and diversity of springtails (Collembola) in the upper soil layer (0–3.8 cm) were studied in a perennial grass-clover ley in NW Norway during April–June 2012. The study was part of a field experiment comparing yields and soil characteristics after application of non-digested slurry (NS) versus anaerobically digested slurry (DS) from dairy cows. In total for three sampling dates, 39 species of springtails were identified. In the Control plots receiving no manure, the density level was around 30 000 individuals (ind.) m2 throughout the whole season. Three days after slurry application (40 t ha -1), the density of springtails had dropped significantly; from 55 214 to 7410 ind. m2 in the NS treatment and from 41 914 to 10 260 ind. m2 in the DS...

Managing soil fertility in organic farming systems
Provedor de dados: 21
Autores: Watson, C.A.; Atkinson, D.; Gosling, P.; Jackson, L.R.; Rayns, F.W.
Complex relationships exist between different components of the organic farm and the quantity and quality of the end products depend on the functioning of the whole system. As such, it is very difficult to isolate soil fertility from production and environmental aspects of the system. Crop rotation is the central tool that integrates the maintenance and development of soil fertility with different aspects of crop and livestock production in organic systems. Nutrient supply to crops depends on the use of legumes to add nitrogen to the system and limited inputs of supplementary nutrients, added in acceptable forms.  Manures and crop residues are carefully managed to recycle nutrients around the farm. Management of soil organic matter, primarily through the...

Cross-linked polyacrylates in post-mining substrates:  persistence and effects on plant growth
Provedor de dados: 21
Autores: Rodionov, A.; Nii-Annang, S.; Fischer, T.; Gattinger, A.; Bens, O.; Raab, T.; Hüttl, R. F.
Application of hydrophilic polymers composed of cross-linked polyacrylate can improve soil water-holding capacity and accelerate the restoration of post-mining substrates. In this work, we studied the persistence of a polyacrylate polymer incorporated into a soil and its impact on plant nutrients at a reclamation site of former lignite mining in Lusatia (Germany). In contrast to autumn application, the incorporation of the polymer enhanced the sequestration of plant-derived carbon in the soil, which was reflected by a significant increase in the concentration of a lignin marker. Attenuated total reflexion–Fourier transform infrared spectra (ATR-FTIR) and total elemental contents in the applied polymer suggested an intensive cation exchange between the...

Enhancing and testing soil quality
Provedor de dados: 21
At present, soil fertility testing is based on soil chemical analysis. Organic amendments, either as manure and compost or residue from preceding crops and green manure, are essential for maintaining and enhancing soil quality and nutrient management in organic farming. Thus, organic farming is dependent on biologically mediated processes and functions of the whole soil system. Soil quality can be defined as soil's ability to function, it is dependent on the purpose of soil use, and it is based on chemical, physical, and biological soil properties. In recent years, there has been increasing interest in soil quality estimations. The aim of the study is to develop a soil quality test applicable for both organic and conventional farming. To achieve this, the...

Autores: Hörtenhuber, Stefan Josef; Weissengruber, Lina; Friedel, Jürgen K.; Möller, Kurt.
An efficient phosphorus (P) recycling from urban areas is becoming an increasing issue due to the scarcity of natural P deposits. In order to assess the environmental performance of different approaches of P recycling, a LCA assessment and risk assessment studies were carried out. Generally, we found the supply of recycled P-fertilisers (RPFs) to be competitive as compared to conventional sources in terms of LCA results analysed in this contribution: per kg P and with exclusion of infrastructure processes, the highest abiotic depletion potential is shown for conventional mineral fertilisers based on phosphate rocks due to the finite mineral P resources. For fossil primary energy demand, the recycled fertilisers (struvites and an ash-based fertiliser...

Biopore characterization with in situ endoscopy: Influence of earthworms on carbon and nitrogen contents
Provedor de dados: 21
Autores: Athmann, Miriam; Kautz, Timo; Huang, Ning; Köpke, Ulrich.
Biopores have been shown to be enriched with plant available nutrients as compared to the surrounding bulk soil and therefore are considered hot spots for the nutrient acquisition especially in the otherwise nutrient-poor subsoil. However, depending on their individual biography, i.e. colonization by plant roots or earthworms, different nutrient status can be assumed. In this study, individual biopores were characterized with respect to signs of earthworm passage using in situ endoscopy, a non-destructive technique for display of pore wall characteristics. Subsequent sampling and analysis of biopore linings and blockages revealed that only biopores with visible earthworm coatings had significantly higher C and N contents as compared to the surrounding bulk...

Increasing number of stockless organic farms give reason to search for new forms of clover-grass (CG) utilization in order to maintain or increase soil fertility and productivity. A quantitative study was carried out among 93 organic farms to identify different forms of CG utilization and their assets and drawbacks on organic farms.  Different ways of CG transfer such as direct transfer (cut &amp; carry) and indirect transfer stockless farms. In addition, seven farms were interviewed about their experiences  with CG transfer practices. The farmers rate CG transfer mainly positive, since it may partially compensate the negative effects on soil fertility through the missing manure on stockless organic farms.

An organic long-term field experiment with two factors has been carried out since 1998 at the experimental station Gladbacherhof, University of Gießen. The effects of  different farm types (with and without lifestock raising) combined with tillage treatments on plants, soil and environment have been investigated. This article  presents results on soil fertility and cash crop yields according to the farm system especially in the 2nd and 3rd rotation. All in all, the superiority of a management system  with cattle over stockless organic farming is demonstrated. The mixed farm type led to higher amounts of humus in the soil and to higher yields. Long term reduction of  humus in stockless farming is not acceptable. Therefore it is advisable that every crop...

Soil enzymes are considered sensitive indicators of soil health but are not well understood in tillage-intensive vegetable systems. The activities of soil enzymes involved in nutrient cycling (β-glucosidase, β-glucosaminidase, alkaline phosphatase, dehydrogenase, aspartase, and L-asparaginase) were evaluated during 6 yr of commercial-scale production in five organic vegetable systems in Salinas, CA. The systems differed in yard-waste compost inputs (none or 15.2 Mg ha–1 yr–1), winter cover crop frequency (annually or every fourth year), and cover crop type (legume-rye, mustard, or rye). Large differences in cumulative organic matter input (7.4 to 136.8 Mg ha–1) from compost and cover crop shoots affected soil enzyme activities. With exception of aspartase,...

Non-inverting Tillage: Early-Stage Effects on Soil Mechanical Behaviour
Provedor de dados: 21
Autores: Munkholm, Lars J; Schjønning, Per; Rasmussen, Karl J.
Organic farmers often claim positive effects of non-inverting and reduced tillage systems. There is a need of quantifying tilth characteristics in the former plough layer of soil converted to such tillage systems. A non-inverting tillage system (NINV) was tested in a field experiment conducted on a Danish sandy loam soil. It included deep loosening and shallow intensive cultivation and was compared to a conventional ploughing-harrowing tillage system (CONV).  A hierarchical analytical procedure was applied in studies of soil fragmentation and soil strength characteristics for the 7-14 cm soil layer. A visual description was carried out and ease of fragmentation was evaluated in the field using a soil drop test. Soil strength was measured in the field with...

Van bodemdilemma’s naar integrale verduurzaming. Casus: Vruchtbaar Flevoland, van bodemdegradatie en diepploegen naar integrale duurzame productie in Flevoland
Provedor de dados: 21
Autores: Staps, J.J.M.; Berg, ter, Coen; Vilsteren, A.; Lammerts van Bueren, E.T.; Jetten, T.H.
De jonge bodem van Flevoland staat bekend als een van de meest vruchtbare van Nederland. Daarom wordt Flevoland ook wel de groentetuin van Europa genoemd. Toch neemt de kwaliteit van de bodem structureel af. Steeds meer akkerbouwers gaan daarom over tot diepploegen, een drastische en slechts tijdelijke oplossing. Een belangrijke oorzaak van de achteruitgang is dat betrokkenen in de agrarische keten het belang van die bodem weliswaar erkennen, maar geen gezamenlijk verantwoordelijkheid nemen. Dit blijkt uit deze publicatie die op 15 april 2015 aan Gedeputeerde Bert Gijsberts van Flevoland is overhandigd.    De onafhankelijke wetenschappelijke Raad voor Integrale Duurzame Landbouw en Voeding (RIDLV) stelt zich als hoofddoel om vanuit wetenschap en...

NDICEA as a user friendly model tool for crop rotation planning in organic farming
Provedor de dados: 21
Autores: Koopmans, Chris J.; van der Burgt, Geert-Jan.
For organic farming systems, the challenge is to become more specific in practices to maintain high standards in sustainability. Soil processes need to be clearly understood if rotations and manure applications are to become more precise.  Simulation models like the NDICEA model help in the design and maintenance of these farming systems. These models play a key-role in the design of organic precision farming.   The NDICEA model has been calibrated for a number of long-term crop rotation experiments. Recently, the model was validated using research data from more than 35 organic farms all over the country. The model is used to calculate soil-specific mineralization rates in precision applications. In a new easy-to-use application, it was developed to...

Provedor de dados: 21
Autores: Berry, P.M.; Stockdale, E.A.; Sylvester-Bradley, R.; Philipps, L.; Smith, K.A.; Lord, E.I.; Watson, C.A; Fortune, S.
On organic farms, where the importation of materials to build/maintain soil fertility is restricted, it is important that a balance between inputs and outputs of nutrients is achieved to ensure both short-term productivity and long-term sustainability. This paper considers different approaches to nutrient budgeting on organic farms and evaluates the sources of bias in the measurements and/or estimates of the nutrient inputs and outputs. The paper collates 88 nutrient budgets compiled at the farm scale in 9 temperate countries. All the nitrogen (N) budgets showed an N surplus (average 83.2 kg N ha-1 year-1). The efficiency of N use, defined as outputs/inputs, was highest (0.9) and lowest (0.2) in arable and beef systems respectively. The phosphorus (P) and...

Impact of reduced tillage on greenhouse gas emissions and soil carbon stocks in an organic grass-clover ley - winter wheat cropping sequence
Provedor de dados: 21
Autores: Krauss, Maike; Ruser, Reiner; Müller, Tortsen; Hansen, Sissel; Mäder, Paul; Gattinger, Andreas.
Organic reduced tillage aims to combine the environmental benefits of organic farming and conservation tillage to increase sustainability and soil quality. In temperate climates, there is currently no knowledge about its impact on greenhouse gas emissions and only little information about soil organic carbon (SOC) stocks in these management systems. We therefore monitored nitrous oxide (N2O) and methane (CH4) fluxes besides SOC stocks for two years in a grass-clover ley – winter wheat – cover crop sequence. The monitoring was undertaken in an organically managed long-term tillage trial on a clay rich soil in Switzerland. Reduced tillage (RT) was compared with ploughing (conventional tillage, CT) in interaction with two fertilisation systems, cattle slurry...

Long Term Field Experiments in Organic Farming
Provedor de dados: 21
A number of cultivation methods in Organic Agriculture, such as diversified crop rotations and the application of organic manure, have a long-term effect, especially on the physical, biological and microbial parameters of soils. It often takes decades for the quantity and quality of soil organic matter to reach a new dynamic equilibrium. Long-term experiments are thus essential to investigate the effects of crop rotations and organic fertilization on soils and, as a result, on crops. The continuation of long-term experiments is therefore of particular importance to Organic Agriculture.    This volume contains a selection of 12 long-term experiments conducted under different site conditions in Germany, the USA, Italy, Denmark, Switzerland, Austria and...

Autores: D'Avino, L.; Priori, S.; Schroers, H.J.; Tangolar, S.; Tardaguila, J.; Giffard, B.; Fantappiè, M.; Costantini, E.A.C.
Degraded areas are frequent in vineyards, even if managed by organic farming, mainly caused by soil truncation, soil erosion, or salts enrichment. Recovering strategies implemented in 19 degraded vineyards in 5 countries within the RESOLVE project concerned: (i) composted organic amendments, or seeding of cover crops (including legumes) for (ii) green manure or (iii) dry mulch. The relationships between vineyard management and pedo-climatic conditions are useful to better understand other contributions dealing with RESOLVE project reported in the present special issue. The results suggested that the nature of degradation requires optimum seedbed preparation to grow green manure crops. Whereas dry mulching plants needs less tillage operations (neither...

Symbiotic nitrogen fixation and N-transfer in a   grass-white clover mixture
Provedor de dados: 21
Autores: Vinther, Finn P.
Symbiotic N2 fixation (SNF) and transfer of fixed N from clover to grass in a grass-white clover mixture was measured during two years using 15N isotope dilution techniques. White clover derived from 87 to 99% of its N from the atmosphere. The total SNF ranged from 150 to 277 kg N ha-1 yr-1, which corresponded to 34-45 mg N fixed per gram of white clover dry weight. The transfer of fixed N from clover to grass corresponded to approximately 10 kg N ha-1 yr-1.

Phosphorus in the coarse soil fraction is related to soil organic phosphorus mineralization measured by isotopic dilution
Provedor de dados: 21
Autores: Wyngaard, Nicolas; Cabrera, Miguel Lorenzo; Jarosch, Klaus A.; Bünemann, Else Katrin.
A sound prediction of soil organic phosphorus (Po) mineralization would be helpful to improve fertilizer recommendations. However, in most mineral soils expensive and time consuming isotopic dilution experiments are required to assess Po mineralization. A proposed method to estimate Po mineralization is the quantification of P in the coarse fraction (CF, &gt;53 μm) of the soil. The aim of this study was to evaluate if P in the CF can effectively predict Po mineralization. Soil samples from three North American long-term arable field experiments (&gt;10 years) with different textures (sand content 15–82%) and different fertilization treatments (non-P-fertilized, mineral P fertilizer, poultry litter) were analyzed. Soil samples were physically fractioned...

All-arable organic farming systems, especially when they are working without organic fertilizer, are often in challenge with their nutrient management to fulfill the requirements of crops. In this context one of the main issues is to mitigate nutrient losses. Here the use of catch crops may one strategy to counteract against this. We hypothesized that under the climate conditions of north-west Germany winter hard catch crops are more suitable to reduce nitrogen (N) losses than catch crops killed by frost, here especially with cereals or legumes as previous crop. In a field experiment in 2015/16 we tested 3 different catch crops (grown in pure stand and in mixture with legumes) after peas and triticale for their nitrogen loss paths over the winter period....

In a field experiment with five different main crop rotations and fives subtypes for organic biogas systems, aggregate stability, organic carbon, total nitrogen and pH were evaluated in the topsoil layer (0-5 cm) in April 2010 in a winter wheat stand. Aggregate stability reacted on variation of crop rotation but not on manuring with biogas slurry. Rotations with a higher percentage of legumes led to a higher aggregate stability. Nitrogen reacted in a similar way while organic carbon and pH were more influence by soil inhomogeneity.

Since the development of effective N2O mitigation options is a key challenge for future agricultural practice, we studied the interactive effect of tillage systems on fertilizer-derived N2O emissions and the abundance of microbial communities involved in N2O production and reduction. Soil samples from 0–10 cm and 10–20 cm depth of reduced tillage and ploughed plots were incubated with dairy slurry (SL) and manure compost (MC) in comparison with calcium ammonium nitrate (CAN) and an unfertilized control (ZERO) for 42 days. N2O and CO2 fluxes, ammonium, nitrate, dissolved organic C, and functional gene abundances (16S rRNA gene, nirK, nirS, nosZ, bacterial and archaeal amoA) were regularly monitored. Averaged across all soil samples, N2O emissions decreased...

Productivity, Soil Fertility and Biodiversity in Organic Agriculture
Provedor de dados: 21
Autores: Fliessbach, Dr. Andreas; Mäder, Dr. Paul.
The DOK long-term field experiment is comparing organic and conventional farming systems since 1978. The systems mainly differ with respect to fertilization and plant protection. The crop yields of the organic systems averaged at 20% of the conventional over three seven-year crop rotation periods. Nutrient input (N, P, K) in the organic systems was 34 – 51 % lower than in the conventional systems, indicating and efficient production. Soil quality as indicated by physical, chemical and biological measures is markedly higher in the organic systems. Organic systems of the DOK trial can therefore be regarded as efficient with respect to productivity and safeguarding environmental quality and biodiversity.

Is the enzymatic hydrolysis of soil organic phosphorus compounds limited by enzyme or substrate availability?
Provedor de dados: 21
Autores: Jarosch, K. A.; Kandeler, E.; Frossard, E.; Bünemann, E. K.
The mineralization of soil organic phosphorus (P) is catalysed by extracellular phosphatases that hydrolyse different non-phytate phosphomonoesters (e.g., sugar phosphates and nucleotides), inositol phosphates (e.g., phytic acids), and phosphodiesters (e.g., nucleic acids, phospholipids). The availabilities of both the organic P compound and the respective phosphatase enzyme jointly determine whether the hydrolysis reaction is substrate limited (enzyme availability &gt; substrate availability) or enzyme limited (enzyme availability &lt; substrate availability), with potential consequences for overall organic P composition and accumulation in soil. Our objective was to evaluate whether the hydrolysis of various organic P compounds in soil is limited by...

Soil Biological Activity Contributing to Phosphorus Availability in Vertisols under Long-Term Organic and Conventional Agricultural Management
Provedor de dados: 21
Autores: Bhat, Nisar, A.; Riar, Amritbir; Aketi, Ramesh; Iqbal, Sanjeeda; Sharma, Mahaveer P.; Sharma, Sanjay K.; Bhullar, Gurbir S.
Mobilization of unavailable phosphorus (P) to plant available P is a prerequisite to sustain crop productivity. Although most of the agricultural soils have sufficient amounts of phosphorus, low availability of native soil P remains a key limiting factor to increasing crop productivity. Solubilization and mineralization of applied and native P to plant available form is mediated through a number of biological and biochemical processes that are strongly influenced by soil carbon/organic matter, besides other biotic and abiotic factors. Soils rich in organic matter are expected to have higher P availability potentially due to higher biological activity. In conventional agricultural systems mineral fertilizers are used to supply P for plant growth, whereas...

Visuell vurdering av jordkvalitet
Provedor de dados: 21
Autores: Pommeresche, Reidun.
I jordbruksjord er jordstruktur resultatet av klima, jordtype, jordarbeiding og agronomi. Planterøtter, meitemark og andre organismer som lever i jorda er også viktige ved at de omdanner organisk materiale til jord og næring, samt flytter alt dette rundt i jorda. Jordkvalitet kan beskrives ved jordas biologisk aktivitet, grynstruktur, farge og lukt. Grav et profil i jorda og se etter meitemark, rotvekst og om røttene går langt ned i jorda. Se også etter knoller (med N2-fikserende bakterier) på røttene til belgvekster (kløver, vikke ol) og sjekk om knollene er rødlige inni (=aktive ). Alt dette indikerer god jordkvalitet. Test jordstrukturen (dårlig, middels eller god) og kvaliteten på jorda di ved å slippe en jordblokk fra 1 m høyde.

Establishment of three strategies in degraded areas within organic vineyards and relevance on soil behaviour, vine physiology and yield components
Provedor de dados: 21
Autores: Caillaud, Caroline.
The main objective of this study was to determine the impact of three organic strategies (organic compost, green manure and dry mulching) on soil’s physical behaviour, vine physiology and grapevine quality, from 2015 to 2017, within two vineyards: FF and SD. The degraded areas chosen had significant higher disruption of the soil, lower yield, but also lower quality of the grape. The two-years application of compost improved significantly the soil structure, the nitrogen and hydric status of the vine. The dry mulching and the green manure didn’t have significant impact. The vintage effect must be taken in account as the climatic conditions from 2015 to 2017 were heterogeneous and the vintage 2017 particularly dry. However, the treatment impact is proved by...

Einfluss von biologischer und konventioneller Bewirtschaftung  auf biologische Bodenqualitätsparameter: Entwicklungen im  DOK Langzeitversuch nach pH-Regulierung
Provedor de dados: 21
Autores: Oberholzer, Hans-Rudolf; Fließbach, Andreas; Mäder, Paul; Mayer, Jochen.
In the long-term DOK field trial at Therwil, Switzerland, agricultural farming systems  are compared since 1978: CONFYM (mineral and organic fertilisers, synthetic  pesticides), BIOORG (organic fertilisers, mechanical weeding and biological disease  and pest control) and BIODYN (with composted manure and bio-dynamic  preparations), all of them at two fertiliser intensities of 0.7 and 1.4 livestock units per  ha, respectively. They are compared with CONMIN (conventionally managed,  exclusively minerally fertilised) and NOFERT (unfertilised control). CONFYM and  CONMIN were limed with 2.7 t CaCO3 ha-1 in 1999, CONMIN with additional 2 t  CaCO3 ha-1 in 2005, since pH values had dropped below officially recommended  values. In spring of 1998 and 2006 soil...

Nitrogen release and synchrony in organic and conventional farming systems of the Central Highlands of Kenya
Provedor de dados: 21
Autores: Musyoka, Martha W.; Adamtey, Noah; Bünemann, Else K.; Muriuki, Anne W.; Karanja, Edward N.; Mucheru-Muna, Monica; Fiaboe, Komi K.M.; Cadisch, Georg.
To match Nitrogen (N) supply to crop N demand, it is essential to understand N release and uptake patterns in different farming systems and crops. To assesses the dynamics of N released in organic and conventional systems and potential synchrony and asynchrony in crop N uptake, a study was conducted over three cropping seasons (potato, maize and leafy vegetables) at two sites in the Central Highlands of Kenya. Mineral-N release and synchrony were monitored in conventional and organic systems at high (recommended N, P, pesticides and irrigation) and low input (low N, P, pesticide use and rainfed) systems. Mineral-N release was assessed using in situ buried bags and N synchrony was measured by the daily differences in N fluxes. The percentage of N applied...

Jordløsning i sædskifteforsøg
Provedor de dados: 21
Autores: Munkholm, Lars J.
Skadelig pakning af underjorden forekommer på en stor del af de dyrkede jord. Særligt er en rodhæmmende pløjesål et udbredt problem. Pakning af underjorden indvirker negativt på både kvantitet og kvalitet af afgrøderne, kan give problemer med at færdes på jorden og har negativ effekt på miljøet. Danmarks JordbrugsForskning har undersøgt effekten af at løsne en rodhæmmende pløjesål i de økologiske sædskifteforsøg på Flakkebjerg og Foulum.     Samlet viser resultaterne fra denne og tidligere undersøgelser, at mekanisk løsning sjældent giver et betydende merudbytte efter løsning. Manglende planteeffekt kan i nogle tilfælde forklares med hurtig genpakning af den løsnede jord. Men selv hvor genpakning er minimeret har vi ikke fundet markant merudbytte efter...

Autores: Erhart, Eva; Siegl, Thomas; Bonell, Marion; Unterfrauner, Hans; Peticzka, Robert; Ableidinger, Christoph; Haas, Dieter; Hartl, Wilfried.
Using biomass from intercrops as feedstock for biogas production makes it possible to produce renewable energy without compromising food production. In order that using intercrops for biogas and fertilizing with liquid digestate is sustainable, it must be secured that this practice does not have adverse effects on soil fertility. Two-year randomised field experiments were conducted on two different soil types near Bruck/Leitha (A). On chernozem soil, soil pH and composition of the cation exchange complex were hardly influenced by liquid digestate. Also on a parachernozem with pH 5.9 short-term effects of liquid digestate were small due to the low salt content and high C/N ratio of the digestate. Nevertheless the distinct increase in soil K content shows...

Decomposition rate of organic fertilizers: effect on yield, nitrogen availability and nitrogen stock in the soil
Provedor de dados: 21
Autores: van Opheusden, A.H.M.; van der Burgt, G.J.H.M.; Rietberg, P.I.
The nitrogen of organic fertilizers does not fully mineralize within a season, and hence will partly become available in later years. This effect is taken into account for the first year but generally not in later fertilizer applications. If it would be taken into account, fertilizer use could be more efficient.  This study is an analysis of a 13-year field trial where crop yield was measured in 13 fertilizer treatments which differ in total N applied and decomposition rate. This is complemented with a model study in which mineralization and soil nitrogen content were calculated.  We intended to show step by step that the use of fertilizers with a low decomposition rate, relative to fertilizers with a high decomposition rate, lead in the course of years to...

Autores: Bending, Gary.
This is the final report of Defra project OF0401. The attached report document starts with an Executive Summary, from which this text is extracted.  The aim of this 1 year study was to examine how key functional indicators of soil quality are affected by contrasting organic and conventional management regimes. In particular, the project investigated the impact of contrasting fertility building regimes on soil quality, focussing on the initial 5-year period following conversion from conventional to organic production.  Five 0.8 ha areas at HRI-Wellesbourne were selected for study. These were: two organic vegetable rotations supporting contrasting fertility building regimes, an organic arable rotation, a grass-clover ley, and a conventionally managed cereal...

How to set up and manage a good compost
Provedor de dados: 21
Autores: Fuchs, Jacques.
This teaching document explains how good compost is made.    Compost is the solid, crumble, brownish to dark brown product of an aerobic degradation of biogenic waste or organic material. There are huge numbers of microorganisms working under constant access of air (oxygen) and with sufficient moisture in the material mix. There is not only degradation, but also formation of new compounds.  Compost has to be treated like a living organism. A healthy compost can bring many advantages to the soil and to the plants, but an unhealthycompost can bring disadvantages for plant growth.

Autores: Gattinger, Andreas; Skinner, Colin; Müller, Adrian; Fließbach, Andreas; Mäder, Paul; Häni, Matthias; Buchmann, Nina; Stolze, Matthias; Niggli, Urs.
Explorative literature searches followed by meta-analyses were conducted to identify differences in soil organic carbon (SOC) and soil-derived greenhouse gas emissions between organic and non-organic farming systems. Within a total of 74 studies we found significantly higher SOC concentrations, SOC stocks and C sequestration rates in organically managed soils compared to those under non-organic management. Meta-analysis of soil-derived GHG flux data from 19 studies revealed lower N2O emissions and higher CH4 uptake rates in soils under organic management when related to acreage. Due to lower yields in organic farming systems higher GHG emissions from these systems were obtained when the data was related to unit crop yield. The poor availability of farming...

Ertrag und Qualitätseigenschaften von Sommerweizen und Kartoffeln bei organischer Düngung tierischer Herkunft (Rottemist) und pflanzlicher Herkunft (Ackerbohnenschrot)
Provedor de dados: 21
Auf Standorten mit sandigen Böden und trockenem Klima ist der Futterbau oftmals standortbedingt stark eingeschränkt, da die Ertragsleistung häufig zu gering ausfällt. Daher verfügen solche Betriebe oft über einen sehr geringen Viehbesatz oder wirtschaften generell viehlos, wodurch die Nutzung von Stallmist als Dünger mitsamt seinen positiven Auswirkungen auf Boden und Pflanzen (Nährstoff-versorgung, Humusersatz) meist gänzlich entfällt. Eine Alternative dazu könnten pflanzliche organische Dünger sein wie z.B. Leguminosen-Biomasse. Deren Effekte auf Boden und Pflanze im Vergleich zu Stallmist wurden bisher jedoch noch nicht rapräsentativ getestet. Dies stellt die Notwendigkeit dieses Projektes dar, durch welches überprüft werden soll, in wieweit es sich bei...

Organic farming and cover crops as an alternative to mineral fertilizers to improve soil physical properties
Provedor de dados: 21
Autores: Sánchez de Cima, Diego; Luik, Anne; Reintam, Endla.
For testing how cover crops and different fertilization managements affect the soil physical properties in a plough based tillage system, a five-year crop rotation experiment (field pea, white potato, common barley undersown with red clover, red clover, and winter wheat) was set. The rotation was managed under four different farming systems: two conventional: with and without mineral fertilizers and two organic, both with winter cover crops (later ploughed and used as green manure) and one where cattle manure was added yearly. The measurements conducted were penetration resistance, soil water content, porosity, water permeability, and organic carbon. Yearly variations were linked to the number of tillage operations, and a cumulative effect of soil organic...

The interest of organic farmers in adopting conservation agriculture principles, including minimal soil disturbance, permanent soil cover and crop rotation has been growing since the early 2000s. However, currently there is no network for organic farmers practicing conservation agriculture, and a lack of knowledge on how organic farmers implement conservation agriculture in practice. Consequently, few technical references are available for organic farmers when they start applying conservation agriculture practices, in particular on controlling weeds without the use of herbicides. The main objectives of this study were: (1) to explore the diversity of conservation agriculture techniques (i.e., reduced tillage, no-tillage and green manures) practiced among...

Soil Organic Carbon and Soil Bio-Physicochemical Properties as Co-Influenced by Tillage Treatment
Provedor de dados: 21
Autores: Fontana, Mario; Berner, Alfred; Mäder, Paul; Lamy, Frederic; Pascal, Boivin.
Soil conservation practices are growingly used with different aims such as reducing fuel consumption and preserving soil organic carbon (SOC). Among others, reduced tillage (RT) often replaces conventional tillage (CT). However, the compared impact of these practices on soil quality remains a matter of controversy. Moreover, the various changes expected are rarely considered all together though they are known to interact. This study aimed at characterizing together the changes in SOC, microbial activity, and a large set of physical properties when comparing RT and CT performed on a clayey soil. Shrinkage analysis allowed to characterize simultaneously the soil pore systems, their volume, air and water content, the hydro-structural stability, and the...

Nitrogen Budgets and Soil Nitrogen Stocks of Organic and Conventional Cropping Systems: Trade-Off between Efficiency and Sustainability of Nitrogen Use
Provedor de dados: 21
Autores: Oberson, Astrid; Jarosch, Klaus A.; Bosshard, Christine; Dubois, David; Frossard, Emmanuel; Hammelehle, Andreas; Mäder, Paul; Mayer, Jochen.
Organic and conventional cropping systems differ in the nature and amounts of nitrogen (N) inputs, which may affect efficiency and sustainability of N use. In the DOK (bio-Dynamic, bio-Organic, Konventionell) field experiment, organic and conventional cropping systems have been compared since 1978 at two fertilization levels. Nitrogen inputs via manure and/or mineral fertilizers, and N exports from plots with harvested products have throughout been recorded. For all treatments, N outputs with harvests have exceeded the inputs with fertilizers. Over the past years, symbiotic N2 fixation by soybean and clover grown in the trial has additionally been assessed, indicating average annual inputs of about 100  kg  ha-1  yr-1 of N fixed from the atmosphere.

Abstract: The objective of this work was to evaluate the soil physical and biological properties in an integrated crop-livestock system (ICLS), with or without cattle grazing, in different seasons. The experiment was carried out in the Cerrado biome, in Brazil, in a Rhodic Eutrudox. The treatments consisted of grazing areas (Urochloa ruziziensis) at 0.25, 0.35, and 0.45 m heights (with soybean cultivation after grazing) and of nongrazed areas. The ICLS had no negative effects on soil bulk density, total porosity, macroporosity, and microporosity. After ICLS implementation, the values of soil bulk density decreased, and those of soil macroporosity increased, in the grazed and nongrazed areas. However, after three years, bulk density and macroporosity were...

Abstract Human pressure on ecosystems has undesirable impacts on human well-being. After the Millennium Project, much interdisciplinary research has been developed worldwide aiming to understand these impacts on ecosystem flows and processes, and to learn about the costs and the benefits of ecosystem services for production. Soil provides many ecosystem services, since its multi-functionality is the basis for food production, water filtration, nutrient cycling, and other goods essential to life. This article presents the main concepts and classifications of soil ecosystem services and of its functions; the indicators and the methods for assessment, modeling, and valuation of ecosystem services; some recent applications to assess and evaluate impacts of...

Autores: MATOS,C.C.; COSTA,M.D.; SILVA,I.R.; SILVA,A.A.
ABSTRACT: The competition between weeds and crops is one of the main factors responsible for productivity losses in agricultural fields. This review aimed at presenting and discussing how the interactions between weeds and microorganisms can affect the competitive capacity of weeds and soil physicochemical properties. We also discuss how changes in the elemental stoichiometry of weeds can reflect their competitive and adaptative capacity. Although weeds are more dependent on associations with soil microorganisms than crops for growth, few studies have assessed the contribution of the soil microbiota to their competitive success in agroecosystems. When in competition, plants can change the elemental stoichiometry of their tissues in environments with varied...

Impact of Land Institutional Factors on Farm Management and Soil Quality
Provedor de dados: 31
Autores: Shuhao,   Tan.
Soil quality has important implications for sustainable agricultural development and food self-sufficiency in many developing countries. A decrease in soil nutrient stocks, one of the components of soil quality, necessitates more inputs and greater management skills in order to compensate for the reduction in nutrients availability. This is why the interaction of agricultural development and soil quality management attracts widespread attention from researchers. Applying plot level data on input/output, and a selected number of soil quality indicators and farm household level information, from the three villages, this paper examines the impact of land fragmentation and land tenure on soil management, the dynamic component of soil quality, crop husbandry...

Autores: Maria,Isabella Clerici De; Chiba,Márcio Koiti; Costa,Alan; Berton,Ronaldo Severiano.
Water resource quality is a concern of today's society and, as a consequence, low pollutant wastewaters and sludges are being increasingly treated, resulting in continuous production of sewage sludge. Sewage sludge (SS) can be used as soil physical conditioner of agricultural or degraded lands, due to its organic C component. The objective of this research was to evaluate the long-term SS effects on soil physical quality of properties such as bulk density, porosity, permeability and water retention of degraded soils treated with annual SS applications. The SS rates were calculated according to the crop N demand. The field experiment consisted of three treatments: mineral fertilization, 10 and 20 Mg ha-1 of SS (once and twice the SS quantity to meet the...

Crop-livestock integration represents an interesting alternative of soil management, especially in regions where the maintenance of cover crops in no-tillage systems is difficult. The objective of this study was to evaluate soil physical and chemical properties, based on the hypothesis that a well-managed crop-livestock integration system improves the soil quality and stabilizes the system. The experiment was set up in a completely randomized design, with five replications. The treatments were arranged in a 6 x 4 factorial design, to assess five crop rotation systems in crop-livestock integration, and native forest as reference of soil undisturbed by agriculture, in four layers (0.0-0.05; 0.05-0.10; 0.10-0.15 and 0.15-0.20 m).

The assessment of soil quality is based on indicators and indices derived from soil properties. However, intrinsic soil properties may interfere with other soil properties that vary under different land uses and are used to calculate the indices. The aim of this study was to assess the extent to which intrinsic soil properties (clay and iron oxide contents) explain variable soil properties (sum of bases, potential acidity, organic carbon, total porosity, and bulk density) under different land uses (native forest, no-tillage and conventional agriculture) on small family farms in Southern Brazil. The results showed that the five properties evaluated can be included in soil quality assessments and are not influenced by the clay and iron oxide contents. It was...

Autores: Calonego,Juliano Carlos; Rosolem,Ciro Antonio.
Soil compaction can be minimized either mechanically or biologically, using plant species with vigorous root systems. An experiment was carried out with soybean (Glycine max) in rotation with triticale (X Triticosecale) and sunflower (Helianthus annuus) in fall-winter associated with pearl millet (Pennisetum glaucum), grain sorghum (Sorghum bicolor) or sunn hemp (Crotalaria juncea) in spring. Crop rotation under no-till was compared with mechanical chiseling. The experiment was carried out in Botucatu, São Paulo State, Brazil. Soil quality was estimated using the S index and soil water retention curves (in the layers of 0-0.05, 0.075-0.125, 0.15-0.20, 0.275-0.325, and 0.475-0.525 m deep). Crop rotation and chiseling improved soil quality, increasing the S...

Mechanical chiseling has been used to alleviate the effects of compaction in soils under no-tillage (NT). However, its effect on the soil physical properties does not seem to have a defined duration period. The purpose of this study was to evaluate the behavior of the bulk density (BD) and degree of compaction (DC) at different soil depths, after chiseling in no-tillage, for one year. The experiment was performed in Ponta Grossa, Paraná State, Brazil, using an Oxisol (Rhodic Hapludox). Bulk density and DC were previously measured in an area under NT for 16 years, then immediately after chiseling (CHI) in May 2009, six months after chiseling (CHI6M) in October 2009 and one year after chiseling (CHI12M) in May 2010. In the layers 0.0-0.10, 0.10-0.20 and...

ABSTRACT Wildfire events cause considerable environmental disturbance but few studies have examined changes in soil properties due to fire. This study aimed to assess the effect of a wildfire event on chemical, physical, and biological properties of the soil in a eucalyptus forest in the Pampa biome. Part of a seven-year-old eucalyptus forest was affected by a wildfire event that lasted for two days. Soil and plant litter sampling was performed in three areas: in the forest that was not affected by the fire, in the forest affected by it, and in an adjacent natural pasture area (the original vegetation). Seven samples were collected from the 0.00-0.05 and 0.05-0.20 m layers of each plot for biological analysis, and three samples were collected for chemical...

To mitigate the impacts of eucalypt monoculture, forestry companies in the Upper Jequitinhonha Valley (MG) have adopted the insertion of strips of native vegetation in-between the commercial plantations. The method used for the creation of these corridors is to allow spontaneous regrowth of native vegetation in areas previously under eucalypt. The objective of this study was to evaluate the effect of cover crops on microbial and soil properties for a detailed description of the restoration process of native vegetation in forest soils of the Jequitinhonha Valley. The treatments were represented by an initial restoration stage (&lt; 4 years) with or without remaining eucalypt and the advanced restoration stage (&amp;gt; 4 years) with or without remaining...

Recovery of soil physical properties by green manure, liming, gypsum and pasture and spontaneous native species¹
Provedor de dados: 90
Autores: Santos Batista Bonini,Carolina dos; Alves,Marlene Cristina.
Inadequate usage can degrade natural resources, particularly soils. More attention has been paid to practices aiming at the recovery of degraded soils in the last years, e.g, the use of organic fertilizers, liming and introduction of species adapted to adverse conditions. The purpose of this study was therefore to investigate the recovery of physical properties of a Red Latosol (Oxisol) degraded by the construction of a hydroelectric power station. In the study area, a soil layer about 8m thick had been withdrawn by heavy machines leading not only to soil compaction, but resulting in high-degree degradation. The experiment was arranged in a completely randomized design with nine treatments and four replications. The treatments consisted of: 1- soil...

ABSTRACT Growth in the agricultural and industrial sectors has increased the demand for rare earth elements (REEs) in the production of technological devices and fertilizers. Thus, the accumulation of these elements in the soil has become an environmental concern. Here, we aim to determine the natural contents of REEs in soils derived from different parent materials and under climatic conditions ranging from humid to semi-arid. We then evaluate the influence of major elements and soil properties on the geochemistry of REEs. The contents of REEs were determined using inductively coupled plasma optical emission spectroscopy. Major elements were determined by X-ray fluorescence spectrometry. The mean content of REEs in soils from Rio Grande do Norte (RN),...

Soil Health refers to the ecological equilibrium and the functionality of a soil and its capacity to maintain a well balanced ecosystem with high biodiversity above and below surface, and productivity. To understand and use soil health as a tool for sustainability, physical, chemical, and biological properties must be employed to verify which respond to the soil use and management within a desired timescale. Attributes with a rapid response to natural or anthropogenic actions are considered good indicators of soil health. Among the physical indicators, soil texture, aggregation, moisture, porosity, and bulk density have been used, while among chemical indicators total C and N, mineral nutrients, organic matter, cation exchange capacity, among others are...

ABSTRACT: The use of crop residues as a bioenergy feedstock is considered a potential strategy to mitigate greenhouse gas (GHG) emissions. However, indiscriminate harvesting of crop residues can induce deleterious effects on soil functioning, plant growth and other ecosystem services. Here, we have summarized the information available in the literature to identify and discuss the main trade-offs and synergisms involved in crop residue management for bioenergy production. The data consistently showed that crop residue harvest and the consequent lower input of organic matter into the soil led to C storage depletions over time, reducing cycling, supply and availability of soil nutrients, directly affecting the soil biota. Although the biota regulates key...

ABSTRACT: Straw returning is an effective way to improve soil quality. Whether the bacterial community development has been changed by long-term straw returning in non-calcareous soil is not clear. In this study, the following five treatments were administered: soil without fertilizer (CK); wheat and corn straw returning (WC); wheat straw returning with 276 kg N ha−1 yr−1 (WN); manure, 60,000 kg ha−1 pig manure compost (M) and wheat and corn straw returning with 276 kg N ha−1 yr−1 (WCN). The high-throughput 16S rRNA sequencing technology was used to evaluate the bacterial communities. The results showed that the community was composed mostly of two dominant groups (Proteobacteria and Acidobacteria). Bacterial diversity increased after the application of...

A simplified Excel® algorithm for estimating the least limiting water range of soils
Provedor de dados: 63
Autores: Leão,Tairone Paiva; Silva,Alvaro Pires da.
The least limiting water range (LLWR) of soils has been employed as a methodological approach for evaluation of soil physical quality in different agricultural systems, including forestry, grasslands and major crops. However, the absence of a simplified methodology for the quantification of LLWR has hampered the popularization of its use among researchers and soil managers. Taking this into account this work has the objective of proposing and describing a simplified algorithm developed in Excel® software for quantification of the LLWR, including the calculation of the critical bulk density, at which the LLWR becomes zero. Despite the simplicity of the procedures and numerical techniques of optimization used, the nonlinear regression produced reliable...

ABSTRACT: Land use change is one of the the major factors related to soil degradation and alterations in soil microbial diversity and structure. In this study, we aimed to evaluate the microbial shifts caused by deforestation of a small area of a natural forest for the introduction of a pasture in the Brazilian Pampa. The microbial abundance and structure were evaluated by molecular approaches based on quantitative Polymerase Chain Reaction (qPCR) and Ribosomal Intergenic Spacer Analysis (RISA). The microbial communities did not present significant quantitative differences, but the environmental impact caused by deforestation changed the structure of the bacterial and archaeal communities. Taking into account the percentage of shared OTUs (operational...

ABSTRACT Although anthropogenic dark earth (ADE) is generally found in non-floodable land, it also occurs on floodplains but, there is no information about the chemical and physical characteristics of ADE in this environment. In this study, we propose to check the hypothesis that a Gleysol, classified as ADE, presents improved chemical and physical conditions than an adjacent soil, no anthropogenic. Thus, the objective of this study was to characterize the chemical and physical properties of the top layer of two ADE profiles in a Gleysol and compare them with an adjacent soil. Samples were taken from two areas classified as ADE in Bragança, Pará State, Brazil, at the "Jabuti" archaeological site, and from an adjacent non-anthropogenic site. Disturbed and...

Abstract: Different physiognomies across the Cerrado could influence the microbial C:N:P ratio in the soil since these physiognomies present different abundance and diversity of plant species. Thus, the aim of this study was to evaluate the microbial C:N:P ratio in soil across three different physiognomies of Cerrado in the Northeast, Brazil, namely campo graminóide (dominance of grasses), cerrado stricto sensu (dominance of grasses, shrubs, low trees, and woody stratum), and cerradão (dominance of woody stratum). Campo graminóide was characterized by lower values of total organic C, N, microbial C:P, N:P, and soil C:N. Cerrado stricto sensu presented average values for most of the measured parameters, while cerradão presented higher values of microbial C,...

ABSTRACT Overliming is an effective way of neutralizing and reducing the toxicity of the hydrolysates generated from acidic pretreatment of lignocellulosic biomass for ethanol production and others biotechnological products. Overliming generates a solid residue whose inadequate disposal may represent an environmental problem. This work aimed at the chemical characterization of the solid residue generated during the detoxification of the sugarcane bagasse hemicellulosic hydrolysate and evaluation of its behavior in soil. The solid residue was submitted to physicochemical and granulometric analysis and determination of the contents of sugars, metals and toxic compounds (acetic acid, furfural, hydroxymethylfurfural and phenols). The potential of the residue...

Soil enzyme activities under long-term tillage and crop rotation systems in subtropical agro-ecosystems
Provedor de dados: 58
Autores: Balota,Elcio Liborio; Kanashiro,Miriam; Colozzi Filho,Arnaldo; Andrade,Diva Souza; Dick,Richard Peter.
Agricultural practices that reduce soil degradation and improve agricultural sustainability are needed particularly for tropical/subtropical soils. No-tillage planting causes minimal soil disturbance and combined with crop rotation may hold potential to meet these goals. Soil enzyme activities can provide information on how soil management is affecting the potential to perform the processes in soils such as decomposition and nutrient cycling. Soil enzyme activities were investigated in a split-plot experiment (3 replications) where tillage (no till and conventional) was the main plot and crop rotation (soybean/wheat, S/W; maize/wheat, M/W or cotton/wheat, C/W) was the subplot. The experiment was established in 1976 in southern Brazil. Soil samples were...

Abstract The sugarcane in Brazil is passing through a management transition that is leading to the abolition of pre-harvest burning. Without burning, large amounts of sugarcane trash is generated, and there is a discussion regarding the utilization of this biomass in the industry versus keeping it in the field to improve soil quality. To study the effects of the trash removal on soil quality, we established an experimental sugarcane plantation with different levels of trash over the soil (0%, 50% and 100% of the original trash deposition) and analyzed the structure of the bacterial and fungal community as the bioindicators of impacts. The soil DNA was extracted, and the microbial community was screened by denaturing gradient gel electrophoresis in two...

Provedor de dados: 117
Autores: Fernández Cirelli,Alicia; Arumí,José Luis; Rivera,Diego; Boochs,Peter  W.
This article reviews the state of the art with respect to the environmental effects of irrigated agriculture on water and soil quality in arid and semi-arid regions on a field scale. Information is scarce and fragmentary. Examples in selected areas of other arid and semi-arid regions in the world clearly show the importance of studying the environmental impact of irrigation practices on water and soil quality. Studies mainly refer to waterlogging and salinization. As regards agrochemicals, fertilizers have been taken into account through nitrate leaching. The impact of micropollutants such as pesticides and heavy metals on water and soil quality is studied mainly by modeling. Pharmaceutical compounds emerge as pollutants when wastewater is used for...

Autores: Araújo,Ademir Sérgio Ferreira de; Melo,Wanderley José de.
Agricultural production systems have to combine management practices in order to sustain soil's profitability and quality. Organic farming is gaining worldwide acceptance and has been expanding at an annual rate of 20% in the last decade, accounting for over 24 million hectares worldwide. Organic practices avoid applications of synthetic fertilizers and pesticides, rely on organic inputs and recycling for nutrient supply, and emphasize cropping system design and biological processes for pest management, as defined by organic farming regulation in the world. In comparison with conventional farming, organic farming has potential benefits in improving food quality and safety. Plant production in organic farming mainly depends on nutrient release as a function...
