Long-term stability and mineralisation rate of compost is influenced by timing of nutrient application during composting of plant residues
Provedor de dados: 21
Autores: Dresbøll, Dorte Bodin; Magid, Jakob; Thorup-Kristensen, Kristian.
The long-term nitrogen mineralization and stability of compost based on easily available plant residues was examined. Four different composts were prepared from wheat straw and clover-grass hay, one treatment receiving all material initially (100/0), two treatments where addition of 75% of the clover-grass was postponed for 3 weeks (75/25,3w) respectively 8 weeks (75/25,8w) and one treatment receiving only 25% of the clover-grass added to the other treatments (25/0). Mineralization and stability of the compost was followed for 24 weeks in leaching tubes, leached regularly by 0.01 M CaCl2. Postponing the addition of the clover-grass hay for 3 weeks (75/25,3w) during composting had a significant effect on the N mineralization rate leading to more mineralised...

Assessment of Alternative Phosphorus Fertilizers for Organic Farming: Chars, Ashes and Slags
Provedor de dados: 21
Autores: Möller, Kurt.
The application of sewage sludge to agricultural land, a common practice to recycle nutrients in the past, is currently prohibited in organic farming due to the risk of soil contamination from pollutants (e.g. toxic and potentially toxic elements, persistent organic pollutants, etc.). Incineration or disposal to landfill of dewatered sludge is costly, leads to greenhouse gas emissions, and eliminates the possibility of nutrient recovery, especially phosphorus. Options to treat dry organic matter are combustion and gasification, among other technologies to produce ashes or chars and to recover the residues for nutrient recycling. Dependent on the technology applied as well as the input material, nutrient concentrations and concentration of contaminants vary...

Disease control with quality compost in pot and field trials
Provedor de dados: 21
Autores: Fuchs, Jacques; Larbi, Mohamed.
Quality compost can have a positive effect on soil fertility and plant growth and health.  This positive effect is not only observable in the laboratory, but also by growers.  Phytopathological problems could be solved with the use of compost.  Durable success can only be obtained if a quality management is resolutely followed.  Further research is needed to optimize the quality management of compost production and  utilization. For example, very little is known about the long-term effect of the different composts on soil fertility and disease receptivity.

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...

Abschätzung des Risikos einer Schwermetall-Akkumulation in  Böden durch längerfristige Anwendung von Recycling-  Phosphor-Düngemitteln
Provedor de dados: 21
Autores: Weissengruber, Lina; Friedel, Jürgen K.; Möller, Kurt.
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...

Autores: von Fragstein und Niemsdorff, Prof. Dr. Peter; Möller, Prof. Dr. Torsten.
Plant based organic fertilisers were tested in plot trials on their effect as N supply for vegetable crops. Radishes (Raphanus sativus L.) and white cabbage (Brassica d-eracea var. capitata L.) were chosen as fest crops. Beside the unamended control four ({R}adish trial) and two ({C}abbage trial) fertilisers were investigated: Castor pomace (Ricinus communis L), pellets of crushed seeds of lupin (Lupinus luteus L), and faba bean (Vicia faba var. minor L.) and Phytoperls® (Zea mays L). They were applied in two N-levels {(R): 80 and 140 kg N ha-1; (C): 120 and 240 kg N ha1 with the two first mentioned fertilisers}. Castor pomace and lupin seed pellets were found to be more efficient N supplies than faba bean seed pellets and Phytoperls®; on the Iow level...

Heterogeneity inside heaps of composting livestock manure and its influence on emission loss of greenhouse gases and ammonia
Provedor de dados: 21
Autores: Hansen, Martin N.
Considerable amounts of methane and nitrous oxide were emitted during storage of solid pig manure generated by slurry separation. The production of greenhouse gases inside the heap was found to be heavily influenced by the oxygen accessibility, which again was influenced by length of storage and the distance to the heap surface. This implies that emission of greenhouse gases from stores of solid manure may be heavily influenced by the size of heaps and the length of storage. Attention should therefore be paid to the size of heap and the length of the storage period when composting studies for inventories of greenhouse gas emission are planned or used.

Einfluss einer Schwefeldüngung zu Kleegras auf Pflanzengehalte, Leguminosenanteil und Ertrag auf einem Sandstandort
Provedor de dados: 21
Autores: Titze, Andreas; Gruber, Harriet.
Auf dem ökologischen Versuchsfeld am Standort Gülzow wurde in zwei Feldversuchen (2013-2018) der Effekt einer Schwefeldüngung im Kleegras getestet. Schwefelmenge, Ausbringungszeit und Düngerart wurden während des Versuchszeitraumes variiert. Die Ergebnisse zeigten wenige Wochen nach der Düngung einen Anstieg der Schwefelgehalt im Boden. Mit Hilfe der Schwefeldüngung konnte in der Regel sowohl der Leguminosenanteil gesteigert als auch der Schwefel- und Proteingehalt in den Pflanzen erhöht werden. Der Trockenmasseertrag stieg besonders durch Sulfatdüngung im Frühjahr an. Nach Düngung mit elementarem Schwefel waren kaum Effekte nachweisbar.

Soil nutrient status and okra pod yield as influenced by plant density and cattle dung manure application
Provedor de dados: 21
Autores: Law-Ogbomo, K.E.; Osaigbovo, A.U.; Ogedegbe, S.
A field was carried out on an ultisol in humid area of Edo State, Nigeria to evaluate the effects of plant density and cattle dung manure application on soil nutrient status and okra pod yield. Treatments consisted of three levels of cow dung (0, 300 and 450 kg N ha-1) and three plant densities (47,619, 66,666 and 83,333 plants per hectare (pph)). A 3 x 3 factorial arrangement fitted into randomized complete block design and replicated three times. Data were collected on soil chemical properties and pod yield of okra. Routine analysis of the soil indicated that the soil was low in nutrient content, thus addition of cattle dung to the soil at various levels influenced the soil nutrient status positively. After cropping with okra, cattle dung application had...

Potential of different composts to improve soil fertility
Provedor de dados: 21
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...

Effect of mycorrhizal inoculation and compost supply on growth and nutrient uptake of young leek plants grown on peat-based substrates
Provedor de dados: 21
Autores: Perner, Henrike; Schwarz, Dietmar; George, Eckhard.
Organic horticultural production systems often are characterized by the use of beneficial soil microorganisms because the application of soluble inorganic P or N fertilizers is not endorsed. Due to the limited supply of soluble nutrients in organic production systems, nutrient deficiency may limit plant growth and yield. The sole use of peat for pot-based cultures is also discouraged in organic production systems. Therefore, we have studied viable alternatives for highly soluble fertilizers and pure peat substrates using leek [Allium ampeloprasum L. var. Porrum] as a test plant. Plants were grown on peat-based substrates with different rates of compost additions, and with and without inoculation with arbuscular mycorrhizal (AM) fungi. Inoculation with a...

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.

Lucerne (Medicago sativa) or grass-clover as cut-and-carry fertilizers in  organic agriculture
Provedor de dados: 21
Autores: Burgt, Geert-Jan H.M.; Eekeren, N. van; Scholberg, Johannes; Koopmans, Chris.
On-farm nitrogen fixation is a driving force in organic agriculture. The efficiency with which this nitrogen is used can be increased by using lucerne (Medicago sativa) or grass-clover directly as sources of fertilizer on arable land: cut-and-carry fertilizers. In two arable crops, the use of lucerne and grass-clover as fertilizers was compared with the use of poultry manure and slurry. The nitrogen-use efficiency at crop level was comparable or better for the cut-andcarry fertilizers as compared to the animal manures. The relative P and K content of these fertilizers came closer to the crop demand than that of the poultry manure. Crop yields were comparable or better when using lucerne or grass-clover as fertilizer. It is concluded that cutand-carry...

Nitrogen losses from grass ley after slurry application - surface broadcasting vs. injection
Provedor de dados: 21
Autores: Uusi-Kämppä, Jaana; Mattila, Pasi K.
As the livestock numbers on Finnish dairy farms have increased and most fields on dairy farms are under grass, it has become common to spread cattle slurry over grasslands. To estimate environmental effects of recurrent slurry applications, a 5-year field study was performed to compare nitrogen (N) losses to water and ammonia losses to air by volatilization, when cattle slurry was either surface broadcast or injected into clay soil after grass cuttings. Slurry was spread on the grass in summer (1996–1997) or both in summer and autumn (1998–2000). Biomass N uptake before grass harvesting and amount of soil mineral N in spring and autumn were measured and field N balances were calculated. Despite cool weather, up to one third of the ammonium N of broadcast...

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...

Composting of tomato wastes and sheep manure: An eco-friendly waste valorisation for enhancing the environmental sustainability in Souss Massa region (Morocco)
Provedor de dados: 21
Autores: Tabrika, Ilyass; Azim, Khalid; Mayad, El Hassan; Zaafrani, Mina.
Each season, a huge amount of crop residues is regenerated by horticultural production. The main type of wastes are tomato stalks, leaves and axillary buds which are subsequently the result of crop operations like trimming and plants trellising and uprooting. The landfilling of corps residues is a serious problem that need to be solved. Therefore, the valorisation of these organic wastes by composting is a simple way for suitable management and the produced compost could be used as an organic amendment to satisfy the crop growth needs and agronomic soil requirements. The aim of the study is to investigate the impact of the mixing proportion of tomatoes residues and sheep manure using an experimental biocomposter of capacity 220 L with passive aeration...

Abstract. Two field experiments were carried from 1999 to 2001 to assess the effectiveness of autumn, winter and spring application of straw-based farmyard manure (FYM). The soil was a sandy loam containing 106 g clay kg-1 situated in the temperate coastal climate of Denmark. The FYM was applied manually to experimental plots at a target rate of 300 kgN ha-1. The manure was incorporated by three initial tillage strategies (harrowing, rotavating or no-tillage) prior to ploughing. All combinations of tillage strategies were also carried out without manure application. Spring barley (Hordeum vulgare L.) was grown, followed by ryegrass (Lolium perenne L.). The results suggest that, as far as circumstances permit, FYM should be applied in spring to achieve the...

Phosphordüngewirkung von Recyclingdüngemitteln
Provedor de dados: 21
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...

Mahepõllumajanduses seab saagikusele tihti piiri  umbrohtumus, kuivõrd konkureeritakse kultuurtaimedega vee, päikesevalguse ja toitainete pärast ning sageli ollakse vaheperemeesteks ka kahjuritele ning haigustele (Hole jt., 2005). Samas suurendavad umbrohud elurikkust ja toetavad põllukoosluse ökoloogilist talitluskindlust, luues toidubaasi taimekahjustajate looduslikele vaenlastele. Seetõttu tuleb taimekasvatusele kasuks nende mõningane olemasolu põllul, ent liigse konkurentsi vältimiseks tuleb nende arvukust siiski reguleerida, kuid loodushoidlikul moel. Selles on üheks olulisemaks  meetmeks läbimõeldult kavandatud külvikord.

Different organic wastes (waste of tomato leaves and stems, sheep manure, olive mill waste and melon waste) were mixed with different proportions for different C/N ratio to make better use of tomato waste as it constitutes the majority of horticultural waste in the Souss-Massa region (south-western of Morocco). The objective of this study was to evaluate the effect of C/N ratio on the physicochemical parameters during aerobic composting process (temperature, relative humidity, pH, EC...), and the quality of the compost. The effect of each produced compost was also tested by its incorporation at different rates into sandy soil. The four studied C/N ratios (treatments) were: C/N=25; C/N=30; C/N=35 and C/N=40. Results revealed that the treatment C/N=35 has...

Improving green manure quality with phosphate rocks in Ontario Canada
Provedor de dados: 21
Autores: Arcand, M M; Lynch, D H; Voroney, R P; van Straaten, P.
Phosphate rock (PR) was applied to one conventional and two organic dairy fields and planted with buckwheat (Fagopyrum esculentum) as a green manure crop. In total, five types of PR were applied at three application rates in order to determine the yield, concentration of P in the aboveground tissue and the P uptake of buckwheat. It was found that PR of relatively high carbonate substitution and small particle diameter could increase buckwheat tissue concentrations to a quality such that mineralization of the buckwheat mulch could occur. Buckwheat mulch and residual PR increased soil P flux as determined by anion exchange membranes in situ in the following spring. This provides evidence that buckwheat of high P quality has the potential to supply P to a...

SOIL ENZYME ACTIVITIES RECOVERY AFTER ORGANIC TREATMENTS OF DEGRADED AREAS WITHIN VINEYARDS
Provedor de dados: 21
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.

Commercial organic fertiliser as supplementary fertilisers in potato crop production
Provedor de dados: 21
Autores: Dierauer, Hansueli; Weidmann, Gilles; Siegrist, Franziska.
The nitrogen requirement varies depending on variety and usage. The conventional fertilisation amounts to 120 kg of N per ha in table potatoes and potatoes for processing. Early potatoes and seed potatoes require slightly less nitrogen at about 100 kg of N per ha.    The nitrogen supply strongly depends on the conditions for N mineralisation (weather, humus content of the soil, preceding crop residues). Thus, optimising the N supply is complex.    Nitrogen from the preceding crop: Grain legumes or cereals in combination with green manure are favourable preceding crops. Field peas may leave behind up to 50 kg net weight of available nitrogen, a mixture of grain legumes and barley up to 30 kg. Depending on the preceding crop and the soil, the nitrogen left...

Moderne staldgødningsspredere opererer med langt større arbejdsbredder end tidligere og er i stand til at sikre en jævnere spredefordeling af fast husdyrgødning, end set for ældre modeller. De testede typer er alle i stand til at sikre en ensartet spredning af både frisk og lagret dybstrøelse, forudsat at arbejdsbredden ikke overstiger en given afstand. Staldgødningsspredere udstyret med et tallerkenspredesystem giver, forudsat brug af større traktorkraft, mulighed for større arbejdsbredde og kapacitet end staldgødnings-spredere udstyret med et spredesystem, bestående af to opretstående spredevalser. Staldgødningsspredere udstyret med et tallerkenspredesystem har til gengæld et relativt større energibehov.

Integrating maize and triticale in grass/clover based dairy systems:  examining yields and autumn soil nitrate levels
Provedor de dados: 21
Autores: Pinxterhuis, Ina; Boer, H. de; Eekeren, N. van; Stienezen, M.W.J.
To establish N-efficient crop rotations with perennial ryegrass/white clover, maize and triticale, a 9-year field experiment was executed on an organic experimental farm in the Netherlands. Crop rotations with different levels of slurry (dairy effluent from the free-stall barn, average dry matter content of 7%) application were tested for dry matter (DM) yield, N yield, soil mineral N in autumn, soil organic matter and soil organic N. Maize cropping and slurry application both increased annual DM yield. However, the second year of grass/ clover following maize, maize itself and slurry applications each resulted in higher soil mineral N in autumn, increasing the risk of nitrate leaching losses. A rotation of 4 years of grass/clover, 2 years of maize and 1...

Efficient use of nitrogen from livestock manure
Provedor de dados: 21
Autores: Askegaard, Margrethe.
Optimized application of nitrogen from livestock manure will reduce nitrogen losses and result in higher yields.  Practical recommendation    Nitrogen application from livestock manure to winter and spring crops has different effects on crop yields depending on the pre-crop and the amount of ammonium-N provided.  The results above show that nitrogen availability from livestock manure is limited. Based on the results, the following recommendations can be made:   • If the pre-crop is not nitrogen-fixing, apply 20 to 60 kg of ammonium-N from livestock manure prior to sowing of crops.  • Livestock manure application to a spring crop after nitrogen-fixing clover-grass is not yield effective and may bear the risk of nitrogen losses.      • If livestock manure is...

The present study revealed that higher grain and stover yield, plant height and number of leaves in maize with panchagavya, cow urine but it was comparable to recommended fertilizer treatments at higher level (200% and 300%). It can be concluded that presence of rich plant growth substances, both major and micro nutrients, beneficial microbial population in organic liquid manures help to bring rapid changes in phenotypic characteristics of plants and also improves the growth and ultimately improve the productivity of the crops. Liquid organic manure like panchagavya could be prepared locally by farming community and obtain increased yield levels. Such practices would pave way to reduce use of external inputs and increase sustainability among organic...

Legume-based catch crops inprove N-supply without increasing the N2O emission
Provedor de dados: 21
Autores: Li, X.; Sørensen, P.; Petersen, S.O.; Olesen, J.E.
Legume-based catch crops (LBCCs) may be an important source of nitrogen (N) in organic crop rotations since they are capable of taking up N both from the soil and from the atmosphere via biological N fixation (BNF). Consequently, they may help improve the crop yield through enhancing soil fertility and crop N supply. On the other hand, the legume-based catch crops may also have a negative impact on the climate as they may enhance the emissions of nitrous oxide (N2O), which is a powerful greenhouse gas.     Therefore, the findings from two research projects HighCrop (Organic RDD 2) and Legume Future (EU-FP7) are promising, as they show that a higher level of N2O emission is not necessarily the consequence of growing LBCC.

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...

Supressive effects of yard waste compost amended growing media on soilborne palnt pathogens in organic horticulture
Provedor de dados: 21
Autores: Bruns, Christian; Schüler, Christian.
Suppressive effects of composts have been demonstrated mainly by American scientists with composted hard-wood bark as a part of container media for ornamentals. In this paper we report about experiments with yard waste- (YWC), biogenic waste- (BWC) and cattle manure compost (CMC) towards the soil borne pathogen Pythium ultimum Trow. There are results included from model composting systems and from yard waste composts originating from two commercial composting plants (C-YWC). It was shown that, in comparison to the other tested composts, YWC from the model composting system was superior in reducing disease incidence caused by P. ultimum on peas. In fifteen cases out of eighteen experiments with addition of 15 % compost the amendment of YWC resulted in...

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,...

Monitoring nutrient turnover during composting has to be based on a constant reference parameter. Is total ash content really a good choice?
Provedor de dados: 21
Autores: Raupp, Dr Joachim.
The total ash content is usually considered to be fairly constant during the composting period, apart from addition of minerals by precipitation and losses by seepage. However, our field trials with farmyard manure have shown that the ash fraction insoluble in hydrochloric acid increased much more than the soluble fraction in the same time. If changes are merely caused by composting intensity (e.g. organic matter degradation), both fractions should be accumulated in the same degree. It is hypothesized that the higher rise of the HCl-insoluble fraction indicates a higher amount of soil material in the heaps at the end compared to the beginning of composting, as the insoluble fraction originates mainly in soil-borne silicates while the soluble fraction is...

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.

Autores: Ciaccia, Dr Corrado; Di Bartolomeo, Dr Emanuela; Calabretta, Dr M.L.; Intrigliolo, Dr Francesco; Tittarelli, Dr. Fabio; Canali, Dr. Stefano.
The aim of the work was to verify the potential of citrus by-products for the production of a quality compost to be used in both conventional and organic farming. Two different composts were produced utilizing Pastazzo (mixture of citrus pulp and skins). One of them, to be used in conventional farming, was prepared adding sludges obtained from citrus industry waste water treatment to pastazzo. The other one, whose final destination was organic farming, was produced without the addition of sludge as starting raw material. Chemical parameters were used to evaluate the characteristics of the final product. Results obtained demonstrated that organic residues from citrus-processing industry could be considered as raw materials for the production of quality...

Autores: Alföldi, Thomas; Schmid, Otto; Gaillard, Gérard; Dubois, David.
In den vergangenen Jahren wurde die Methode der Ökobilanzierung weiterentwickelt und an die Bedürfnisse der Landwirtschaft angepasst. Mit vergleichenden Ökobilanzen wurden bereits bisher die Umweltauswirkungen der biologischen und integrierten Anbauweise erfasst. Diese Arbeiten beschränken sich jedoch auf die Ebene der Einzelkultur. Im vorliegenden Beitrag stellen wir vergleichende Ökobilanzen über eine ganze Fruchtfolgeperiode vor, die wir im Rahmen eines langjährigen Vergleichsversuches (DOK-Versuch) durchführten. Unter diesen Bedingungen schnitt das organisch- biologische Verfahren ökologisch besser ab als das konventionelle/integrierte.

Phosphat-Mobilisierung durch Haupt- und Zwischenfrüchte nach Düngung von weicherdigem Rohphosphat im ökologischen Landbau
Provedor de dados: 21
Im Ökologischen Landbau ist weicherdiges Rohphosphat als Phospatdüngemittel zugelassen. Die Effizienz von Rohphosphatdüngemitteln wird insbesondere durch den pH-Wert des Bodens sowie die Phosphat- und Ca-Konzentration der Bodenlösung beeinflusst. Zur Förderung und Stabilisierung der Bodenfruchtbarkeit werden die Böden gekalkt, so dass der pH-Wert mineralischer Böden meistens über 6 liegt. Kalkung dient nicht nur der pH-Wert-Stabilisierung, sondern durch die Zufuhr von Ca2+ wird auch die Bodenstruktur gefördert und stabilisiert. Darüber hinaus wirkt die Kalkung aber einer höheren chemischen Löslichkeit der Rohphosphate entgegen. Die daher auf mit Rohphosphat gedüngten Flächen (mit pH über 6) niedrigere Phosphatfreisetzung kann für die Phosphaternährung...

Opportunity costs for maize associated with localised application of sewage sludge derived fertilisers, as indicated by early root and phosphorus uptake responses
Provedor de dados: 21
Autores: Lemming, Camilla; Oberson, Astrid; Hund, Andreas; Jensen, Lars Stoumann; Magid, Jakob.
Background: Phosphorus recycling from waste and localised placement of fertilisers can potentially improve sustainable P management in agriculture. However, knowledge about root and plant P uptake responses to placement of complex waste-derived fertilisers is lacking.   Methods: Sewage sludge (SS) and sewage sludge ash (ASH) were tested against triple superphosphate (TSP) in a rhizobox setup where maize shoot and root growth and architecture were followed for 30 days. The three P sources were either mixed homogenously into the soil (slightly acidic, low in available P and moderate P fixing capacity; labelled with 33P) or localised in a patch close to the seed.  Results: Localisation of TSP and SS both induced increased root length density in and around the...

Organic farms without or with a too low animal livestock try to replace farmyard manure by using plant based organic fertilizers, e.g. legume biomass as green meal or grain meal. When applying such fertilizers, it is necessary to know their nitrogen mineralisation intensity in relation to farmyard manure. In an incubation test over three weeks (25 °C, 45% maximum water holding capacity) alfalfa meal showed a lower and faba bean meal a much higher nitrate N mineralisation than farmyard manure (15 and 69 ug g-1 dry matter, respectively, compared to 25).The largest amount was released from castor meal (99 ug g-1). After one week farmyard manure had the largest N release with 28 ug g-1.

Composting has been acknowledged as an emission reduction methodology by the UNFCCC. The emission reduction reached by a composting project is determined by comparing the composting scenario with the applicable baseline scenario. The objective of this study was on the one hand to clarify the emission reduction methodology of a composting facility in Egypt and on the other hand to extend this methodology with an example to illustrate the effect of compost use on greenhouse gas emissions. In this study, the emissions in a scenario where compost originating from a compost facility near Alexandria is used on a citrus farm in Egypt, were compared with a hypothetical baseline scenario where organic waste is not recycled and chemical fertilizer is used on the...

In the present study, AMF root colonisation of potato plants was compared between organically and minerally fertilised field plots, which did not significantly differ in the total amount of plant available P. The AMF root colonisation was increased in response to organic fertilisation. This indicates that organic fertilisation can enhance AMF development independently from the soil P fertilisation level. Furthermore, soil grown mycelium was trapped in fungal compartments. This technique allowed the extraction and quantification of coarse and finely branched soil grown hyphae after harvest. The soil in the fungal compartments was either fertilised with low or with high amounts of mineral P. In organically fertilised field plots, the amounts of finely...

Decomposition rate of organic fertilizers: effect on yield, nitrogen availability and nitrogen stock in the soil
Provedor de dados: 21
Autores: Opheusden, A. H. M.; Burgt, Geert-Jan 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...

Biogas from manure – a new technology to close the nutrient and energy circuit on-farm
Provedor de dados: 21
Autores: Schäfer, W.; Evers, L.; Lehto, M.; Sorvala, S.; Teye, F.; Granstedt, A.
The Biodynamic Research Institute in Järna developed a two-phase on-farm biogas plant. The plant digests manure of dairy cattle and organic residues originating from the farm and the surrounding food processing units containing 17.7-19.6 % total solids. A new technology for continuously filling and discharging the hydrolysis reactor was developed and implemented. The output of the hydrolysis reactor is separated into a solid and liquid fraction. The solid fraction is composted. The liquid fraction is further digested in a methane reactor and the effluent used as liquid fertiliser. Initial results show that anaerobic digestion followed by aerobic composting of the solid fraction improves the nutrient balance of the farm compared to mere aerobic composting....

Autores: Tresch, Simon; Fliessbach, Andreas.
Comparer la décomposition du thé vert comme un matériau de décomposition rapide avec le thé rooibos comme un matériau qui est difficile à décomposer, permet de calculer l'Indice du Sachet de Thé (Tea Bag Index TBI). Cela fournit des informations sur la capacité du sol en tant qu'organisme vivant à transformer les résidus organiques en nutriments disponibles pour les plantes et à contribuer a l'accumulation d'humus dans le sol. Cette technique est facile à ppliquer. Placez le sachet de thé dans le solet sortez‐le après trois mois pour déterminer combine il reste de matière. Il est fascinant de découvrir le résultat de nos petits auxiliaires travaillant dur dans le sol et comment ce travail fournit des nutriments à une nouvelle génération de plantes.

Effects of plant based organic fertilizer (faba bean meal) compared to farmyard manure on yield and quality of potatoes and soil organic matter levels
Provedor de dados: 21
Autores: Raupp, Dr Joachim; Oltmanns, Meike.
Whereas the positive effects of farmyard manure on soil biological properties have been shown in several long-term experiments, no comparable information was available for plant based organic fertilizers. Since 1996 such materials were applied with the same amount of total nitrogen as farmyard manure (100 (kg ha-1) on a poor sandy soil. In 2005 it  was found that faba bean meal application caused the same potato yield, and tubers with the same phosphorus content, but lower potassium and slightly increased starch contents compared to farmyard manure. Tuber quality was similar as regards nitrate content. However, as regards crude extract darkening better values have been achieved by farmyard manure. Soil organic matter content was lower with faba bean meal...

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...

Potentially mineralizable nitrogen is soils green manured with biocidal crops
Provedor de dados: 21
Autores: Marchetti, Rosa; Lazzeri, Luca; Malaguti, Lorena; Orsi, Anna; Ponzoni, Gilda.
Biofumigant crops used as green manure, in addition to producing a biocidal effect on some soil-borne pathogens and pests, could represent a source of N for crop nutrition. In two laboratory experiments we compared i) the potentially mineralizable N (PMN) of a silty clay soil after incorporation of glucosinolate-containing (GLS+) and non-containing (GLS–) plants, or after incorporation of metam sodium; and ii) the mineralization rate of different types of soils (silty clay, loam and loamy sand) after green manuring with GLS+ crops. After a 3-month incubation, the PMN of the silty clay soil amended with the GLS+ Brassica juncea was significantly higher than the unamended control and the soil amended with Triticum aestivum and Eruca sativa. Metham sodium,...

Fractions of particulate organic matter in soils depending upon farmyard manure and mineral fertilization
Provedor de dados: 21
Autores: Raupp, Dr Joachim; Oltmanns, Meike.
In a long-term fertilization trial particulate organic matter (POM) was investigated after 20 years of farmyard manure vs. mineral fertilization at different levels with the method of Meijboom et al. (1995). The organic matter was separated with sodium polytungstate (Magid et al., 1996; Six et al., 1999) into a light (p &lt;1.13 g cm-3), medium (1.13-1.37 g cm-3) and heavy (p &gt;1.37 g cm-3) fraction.   The organically fertilized plots had lower contents of the light fraction (0.73 - 0.78 g kg-1 dry matter on average of all fields) compared to the mineral treatment (0.95 g kg-1 TS). This gives a hint that organic residues are decomposed faster in the manure fertilized soil, according to the higher biological activity found earlier in this treatment. The...

Modelling N2O emissions from organic fertilisers for LCA inventories
Provedor de dados: 21
Autores: Meier, Matthias S.; Schader, Christian; Berner, Alfred; Gattinger, Andreas.
Apart from mineral fertilisers, organic fertilisers act mainly via the soil C-N pool in order to provide available nitrogen to plants. This different mode of action is not reflected so far in the current IPCC N2O emission model. Here we propose a simple model to calculate N2O emissions from organic fertilisers and plant residues. It considers the long-term immobilisation of N within stable organic matter in the soil as well as the mineralisation of additional N from the soil pool. A first test with field data showed reliable simulations of measured N2O emissions. By comparing values generated by our model with values generated by the IPCC model we show that the IPCC model may overestimate emissions from organic fertilisers. Therefore, within LCA...

Autores: Angeringer, Wolfgang; Starz, Walter; Karrer, Gerhard.
In 2012 about 25 % of permanent Austrian grasslands were managed organically. At the same time the farms enlarged their average field areas especially in Alpine regions. In order to investigate intensification limits of montane meadows, an on-farm field experiment at the Upper Styrian Pöls valley was established in 2008. The triannual case study consisted of a balanced incomplete block design with 30 sub-plots at two autochthonous meadows of the Trisetetum association. These examined six treatments with different cutting regimes (2, 3, 4 cuts per year) and either slurry or solid manure for organic fertilization. Three years of investigation describe changes in coverage of grassland species as well as yield quantity and quality. The results show changes in...

Autores: Toom, Merili; Lauringson, Enn; Talgre, Liina; Tamm, Sirje; Narits, Lea.
Cover crops are essential in fallow periods of cropping systems to protect the soil from erosion and loss of plant nutrients through leaching and runoff (especially in winter). Experiments with potential cover crop species were carried out to evaluate their suitability to the local climate. The biomass production of tested cover crops in the experiment that lasted for two years was different depending on the length of the growing seasons.

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: Donatiello, Dr. Sergio; Fagnano, Dr. Massimo.
Due tipi di sovescio  (favino puro e favino + avena) con due epoche di interramento (inizio aprile e fine aprile) in combinazione fattoriale, sono stati confrontati in una azienda sperimentale della Campania, per valutare gli effetti sulla produzione di pomodoro.  Dai primi risultati, si può evidenziare come la fertilità residua del terreno, dovuta alla precessione di leguminose, è stata sufficiente a sostenere almeno in parte le produzioni di pomodoro (311 q ha-1).   Gli apporti di N sono stati più alti nel caso del sovescio di favino puro e con l’interramento tardivo: 72 e 142 kg ha-1 di N per il favino e 45 e 80 kg ha-1 di N per il sovescio misto, rispettivamente nelle due epoche di interramento.

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...

Prosjektet “Forsøk med fermentering av husdyrgjødsel» (2016-2018) prøver ut tilsetning av effektive mikroorganismer (EM) i dyrerom og gjødsellagre på noen gårder i Norge. Et kontrollert forsøk ble gjennomført på Tingvoll vinteren 2017-18. Uttrykket «effektive mikroorganismer» ble først brukt i Japan, der forskere isolerte og dyrket opp stammer av ulike jordboende sopp og bakterier, og prøvde dem ut i ulike kombinasjoner som tilsetning til dyrka jord. Ideen var å utkonkurrere den stedlige mikrofloraen og få sunnere planter og bedre avlinger. Metoden har fått vid anvendelse i Asia, og knyttes ofte til begrepet «nature farming» eller «Kyusei nature farming». Også i Europa er det nå mange produkter på markedet som inneholder EM.

Long term effect of organic sources of nutrients on productivity and soil health in maize+soybean—wheat+gram cropping system
Provedor de dados: 21

Organic farming has emerged as an important priority area globally in view of growing demand for safe and healthy food which provides health and environmental benefits. The long term sustainability and concerns on environmental pollution associated with indiscriminate use of agrochemicals calls for use of organic farming practices in agriculture for maintaining soil health and crop productivity. Over the past few decades, increasing attention has been given to intercropping particularly in organic agricultural systems and the evidence suggests that this can provide production advantages over sole crops in the absence of increased external inputs due to more efficient utilization of resources. Component crops in intercropping may differ in their use of...

Fertilisation de la courge de plein champ : test de différentes doses et de 2 types d'engrais - rapport final 2005
Provedor de dados: 21
Autores: Védie, Hélène.
La fertilisation en maraîchage biologique est sans aucun doute encore un vaste domaine à explorer. Le manque de références sur les besoins des cultures d’une part, et sur les possibilités de fournitures du sol par minéralisation d’autre part, amène bien souvent les producteurs à « naviguer à vue » en utilisant des doses standards, qui ne reposent pas sur des bases agronomiques éprouvées.  Les suivis réalisés par le GRAB sur aubergine en 2003 et melon en 2004 montrent qu’il est possible de diminuer les doses d’engrais azotés, sans perte de rendement. La marge de manœuvre est très importante en bio, où les fournitures par le sol sont sans doute largement sous-estimées. Des essais de fertilisation en maraîchage biologique sont donc encore nécessaires afin de...

Entwicklung einer praxisanwendbaren Methode der Humusbilanzierung im ökologischen Landbau (Verbundvorhaben)
Provedor de dados: 21
Die Humusversorgung acker- und gemüsebaulich genutzter Böden nimmt im ökologischen Landbau eine zentrale Stellung ein. Über die Fruchtfolge und den Stickstoffkreislauf sollte in Betrieben eine optimale Humusreproduktion gewährleistet werden, da ein Absinken der Humusgehalte unterhalb tolerierbarer Werte langfristig eine Abnahme der Bodenfruchtbarkeit und der Ertragspotentiale mit sich bringt. Aus verschiedenen Gründen ist es bisher sehr schwierig, den Humusstatus ackerbaulich genutzter Böden einzuschätzen oder Schlussfolgerungen zur Optimierung des betrieblichen Humusmanagements zu ziehen. Die bisher vorliegenden Instrumente zur Analyse der Humusversorgung (Messverfahren, Bilanzmethoden, Simulationsmodelle) wurden fast ausschließlich für die Bedingungen...

The potential of different plant based organic fertilisers (PBOF) to substitute animal based organic fertilisers (ABOF) in organic vegetable production were investigated in incubation, pot and field experiments. PBOFs have the potential to replace ABOFs. Particularly legume seed meals show fast net N-release even at low soil temperatures. Considerable differences in nitrate contents of vegetables can be found between the different fertilisers although fresh matter and N yields are nearly identical.

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...

Organic farming systems should be characterized by excellent soil fertility management to keep plant nutrient cycles short and as closed as possible.  Therefore, it is extremely important to establish growing systems that have rotations with appropriate crops and intercrops to ensure fertile and biologically active soils, to enhance biodiversity and to provide high quality crop yields. Locally available organic  fertilizers include green manures and animal manure. The influence of green manures as intercrops and these combined with composted cattle manure on soil properties, biodiversity indicators and crop yields was studied in a crop rotation experiment in three organic systems at the Estonian University of Life Sciences.

N-Freisetzung aus organischen Handelsdüngern – Übersicht und eigene Versuchsergebnisse im ökologischen Gemüsebau. [N-Mineralisation of organic  fertilizer - Review and own results in organic vegetable production]
Provedor de dados: 21
Autores: Laber, Hermann.
Anfang der 90er Jahre setzte eine intensive Feld-Versuchstätigkeit zu Fragen der N-Düngung mit organischen Handelsdüngern ein. Dabei wurde in erster Linie, zumeist unter ökologischen Anbaubedingungen, die Ertragswirksamkeit verschiedener Dünger miteinander verglichen. Ergebnisse von Brutversuchen geben erste Hinweise auf das Mineralisationsverhalten, das unter Feldbedingungen bis dato kaum untersucht wurde. Hierzu werden eigene Versuchsergebnisse im Kontext mit den verfügbaren Literaturdaten vorgestellt.

Comparison of the environmental performance of different treatment scenarios for the main phosphorus recycling sources
Provedor de dados: 21
Autores: Hörtenhuber, Stefan Josef; Theurl, Michaela Clarissa; Möller, Kurt.
Efficient phosphorus (P) recycling from rural and urban areas is becoming an increasing issue due to the scarcity of natural P deposits. Based on a life cycle assessment (LCA), we analyzed the environmental performance of 17 different P supply and recycling approaches from urban wastes, biosolids and slaughterhouse wastes compared with the two conventional inorganic fertilizers phosphate rock and triple superphosphate. The results show that many recycled P fertilizers (RPFs; e.g., digestates from urban organic wastes, biosolids and their ashes, meat and bone meal (MBM) and its recycling products) are competitive in terms of LCA results compared with conventional P fertilizers. For each of the P recycling sources, one or more treatment options were...

Autores: Engelmann, Pia; Scheu-Helgert, Marianne; Schubert, Wilhelm; Rascher, Birgit; von Mansberg, Arved.
Der intensiv wirtschaftende ökologische Gemüsebau ist auf Zufuhr von organischen stickstoffhaltigen Materialien angewiesen. Seit der BSE-Krise werden verschiedene organische Materialien pflanzlicher Herkunft als Alternative zu Düngern tierischer Herkunft betrachtet.  Organische Handelsdünger pflanzlicher Herkunft und Leguminosenschrote wurden in Freilandversuchen verglichen und bezüglich ihrer Düngewirkung bei verschiedenen Gemüsekulturen überprüft. Im ersten Versuchsjahr wurden in Vorversuchen im Gemüsebauversuchsbetrieb Bamberg der LWG Veitshöchheim verschiedene pflanzliche Dünger, ein betriebseigener Kompost und ein Horndünger auf deren Ertragswirksamkeit getestet. In den folgenden Vegetationsperioden wurden die N-Umsetzung verschiedener Materialien und...

Energy crops for biogas production need to be integrated into sustainable and site  adapted crop rotation systems, minimising the competition with food production.  Luzerne/clover (-grass), sun flower, maize, green-rye + maize and vetch-rye + maize  were compared at two sites in Austria with semi-arid (Raasdorf) and humid (Lambach)  conditions with and without biogas slurry application. The yield of legumes and  fertilised non-legumes at the humid site were 9 % to 56 % higher then at the semi-arid  site. The 2-crop system maize following vetch-rye achieved the highest yields at both  sites. Slurry from the biogas plant increased the yield only at the humid site.

Nitrogen use efficiency of cereals in arable organic farming
Provedor de dados: 21
Autores: Olesen, Jørgen E.; Rasmussen, Ilse A.; Askegaard, Margrethe.
The effect of nitrogen (N) supply and weeds on grain yield of spring barley, winter wheat and winter rye was investigated from 1997 to 2004 in an organic farming crop rotation experiment in Denmark on three soil types varying from coarse sand to sandy loam. Two experimental factors were included in the experiment in a factorial design: 1) catch crop (with and without), and 2) manure (with and without). The apparent recovery efficiency of N in grains (nitrogen use efficiency, NUE) from NH4-N in applied manure varied from 29 to 38% in spring barley and from 23 to 44% in winter cereals. The NUE of above-ground N in catch crops sampled in November prior to the spring barley varied from 16 to 52%, with the highest value on the coarse sandy soil and the lowest...

Gross phosphorus fluxes in a calcareous soil inoculated with Pseudomonas protegens CHA0 revealed by 33P isotopic dilution
Provedor de dados: 21
Autores: Meyer, Gregor; Bünemann-König, Else; Frossard, Emmanuel; Maurhofer, Monika; Mäder, Paul; Oberson, Astrid.
Inoculation with phosphorus (P) solubilizing bacteria is being proposed to increase P availability for plants by mineralization and solubilization of non-available soil and fertilizer P. Solubilization of inorganic P compounds by bacterial strains has repeatedly been shown on agar plates and in liquid media. However, the effects of inoculation on P availability to plants growing in soils, either in pot or field studies, are inconsistent and do not allow to separate between direct effects on P availability and indirect effects such as improved plant health. This differentiation could be achieved using 33P isotopic labeling. We applied the 33P isotopic dilution method in a pot and in an incubation experiment to study gross P fluxes in a calcareous soil...

Digested slurry as a fertilizer for biogas ley
Provedor de dados: 21
Autores: Kapuinen, Petri; Perälä, Paula; Regina, Kristiina.
Digested slurry injected produces in this case comparable yields with mineral fertiliser. Because the primary growth is the largest and of the best quality it should be used for feed as the first option. The re-growths could then be used as a co-substrate in biogas reactors. Digested slurry is a good fertiliser for leys when injected. Injection of non-digested slurry reduces the ammonia emissions and leaching of soluble phosphorus but the significance of the low performance of nitrogen leaves open its fate.

Root growth and nitrogen uptake of carrot, early cabbage, onion and lettuce following a range of green manures
Provedor de dados: 21
Autores: Thorup-Kristensen, K.
An experiment was performed to study the significance of rooting depth of four vegetable crops on their utilization of green manure nitrogen (N). Rates of rooting depth development were estimated as approximately 0.2, 0.7, 1.2 and 1.2 mm day C)1 for onion, carrot, lettuce and cabbage, respectively. At harvest, onion and lettuce were found to be shallow-rooted with final rooting depths of only 0.3 and 0.6 m, respectively, whereas carrot and cabbage reached rooting depths of at least 1.1 m. The two deep-rooted vegetables increased their N uptake by 46, 24 and 7 kg N ha)1 when following winterhardy  legumes, non-hardy legumes and rye, respectively; the equivalent responses by the two shallowrooted crops were 23, 9 and 15 kg N ha)1, respectively.

Autores: Raupp, J.; Dobiaschowski, L.; Oltmanns, M.
Mit dem niedrigem Düngungsniveau erzielte Mineraldüngung einen höheren Ertrag als Stallmist, bei hoher Aufwandmenge jedoch waren die Mistvarianten überlegen (bis zu 28 dt ha-1). In unserem Versuch standen 50 Pflanzen pro m-2, ohne sicheren Einfluss der Düngung. Das Tausendkorngewicht und der Fettgehalt der Körner blieben ebenfalls ohne signifikanten Düngungseffekt. Der Rohproteingehalt der Körner war mit mineralischer Düngung immer höher als mit organischer und stieg bei jeder Düngungsart von der mittleren zur hohen Aufwandmenge signifikant an.

Auswaschungsverluste unter biologischer und konventioneller Bewirtschaftung
Provedor de dados: 21
Autores: Hein, Waltraud; Waschl, Hermann.
In this project, located at Winklhof, a comparison between organic and conventional farming is done. The field trial combines a crop rotation with two levels of fertilisation intensities (one is 1.0 LU ha- and the other is 1.8 LU ha-1). The fertilisation-systems are stable-manure and liquid manure, the treatments were done organically. The aim of this project is to find out which production system is better for the environment in spite of crop yield, product quality and leaching losses. The last parameter was measured in lysimeters. A high amount of yearly precipitation could account the high amount of seepage water. Consequently the leaching losses of both production systems could be compared.

Synchronisation der N-Mineralisierung aus Mulch mit der N-Aufnahme von Freilandgemüse durch optimiertes Management einer Leguminosengründüngung
Provedor de dados: 21
Im ökologischen Landbau stellen der Beikrautdruck, die N- und Humusversorgung zentrale Probleme der Fruchtfolge dar. Ertrag, Ertragssicherheit und der Pflegeaufwand werden davon direkt bestimmt. Leguminosenhaltige Grünbrachen in der Fruchtfolge mindern besonders den Unkrautdruck und verbessern die Humusbilanz. Ihre N-Wirkung fällt dagegen bisher unbefriedigend aus, da der oft kurzfristig hohe N-Bedarf der Gemüsepflanzen nicht gedeckt werden kann. Auch über Winter abfrierende Gründüngungspflanzen zeigen oftmals nur eine schwache Düngerwirkung, weil die Gemüsepflanzen nur ein geringes Wurzelsystem haben, das keinen Zugang zu dem tiefer im Boden verlagerten Stickstoff hat. Es soll deshalb untersucht werden, ob durch den Anbau einer Gründüngung in Verbindung...

Production of potato crisps and chips in organic farming: Effect of sprinkler irrigation, manure and preceeding crop management of clover grass on yield and quality
Provedor de dados: 21
Autores: Krause, Tanja; Böhm, Herwart; Loges, Ralf; Taube, Friedrich; Haase, Norbert U.
In contrast to conventional agriculture the nutrient supply in organic potato production must be secured by preceding crop or organic fertilization. On lighter sites nitrogen mineralisation of organic fertilisation depends highly on water supply. Over two years field experiments with sprinkler irrigation relating to different manure fertilization and varied clover grass management systems (mulching, cut mowing) has been conducted and effects on yield, grading and qualitative properties of  processing potatoes has been surveyed. The tested clover grass management systems showed only a low effect on yield and quality on the following crop potato. In 2003 a small yield increase was  achieved by the mulching system. In the dry year 2003 the sprinkler...

The use of composted woodchip as a substrate for growing varieties of edible mushrooms
Provedor de dados: 21
Autores: Frost, D; Clarke, A.
The world market for edible mycorrhizal mushrooms has experienced considerable growth over the past two decades with annual production estimated to exceed 14 billion USD. The market continues to grow due to interest in the nutritional and health benefits of edible mushrooms. The size of the market for speciality mushrooms has also increased and the overall market trend has been towards fresh rather than canned product. There are a number of different cultural methods in commercial use, with a wide variety of species produced on different substrates. The aim of this project was to evaluate woodchip compost as a substrate to produce edible mushrooms. Woodchip compost appears to have potential as a growing medium but more development is necessary to make this...

Organische Handelsdünger: Vergleich der Stickstoffwirkung in einer frühen Brokkolikultur
Provedor de dados: 21
Autores: Koller, Martin.
Der Herbst 2004 brachte einiges an Bewegung in den Bio-Düngermarkt: Mehrere neue und erst noch kostengünstige Produkte auf der Basis von Federmehl kamen neu in die Bio-Hilfsstoffliste. Zudem ist seit 2005 Fleischknochenmehl in der Schweiz in Lebensmittelqualität neu wieder zugelassen. Diese Dünger waren in ihrer Wirkung im Feld wenig bekannt. Insbesondere über das Mineralisierungsverhalten im Frühjahr lagen noch keine Daten vor. Um da mehr Klarheit zu schaffen, hat sich das FiBL entschlossen, zusammen mit Düngerhandels- und Produktionsfirmen eine Auswahl dieser neuen Handelsdünger in einer stickstoffbedürftigen Frühkultur zu testen.   Biorga Quick Neu und Landor N-Bio zeichnen sich durch eine schnelle Düngerwirkung aus. Die sehr gute Pelletierung und das...

Einfluß gesteigerter organischer und mineralischer Düngung und biologisch-dynamischer Präparate auf Ertrag, Qualität und Lagerfähigkeit von Kartoffeln
Provedor de dados: 21
Autores: Schulz, D. G.; Gmelin, C.; Mehrens, A.; Sabiwalsky, B.; Köpke, U.
Die gesteigerte Düngung ergab an beiden Standorten bei den meisten Parametern die erwarteten Effekte. Eine Wirkung der biologisch-dynamischen Präparate, entweder getrennt in Kompost- und Spritzpräparate, oder kombiniert angewendet, konnte ebenfalls bei mehreren Parametern nachgewiesen werden. Allerdings ist nach wie vor nicht klar, unter welchen Umständen diese Präparate wirken und warum sie z.T. gegensinnige Effekte haben. In dem hier vorgestellten Projekt stehen zur Zeit aus den letzten beiden Versuchsjahren noch diverse Parameter, u.a. einige Inhaltsstoffe (z.B. Ascorbinsäure, Nitrat, Mineralstoffe) zur Analyse und Auswertung aus. Aus diesen Ergebnissen und denen der nächsten fünf Jahre erwarten wir in der Zusammenschau mit den Ergebnissen unserer...

Utilization of nitrogen in legume-based mobile green manures stored as compost or silage
Provedor de dados: 21
Autores: Sørensen, Peter; Kristensen, E.; Odokonyero, K.; Petersen, S.O.
The utilization of nitrogen (N) in green manure leys can be improved by harvesting, storage and spreading of the plant material as manure in other crops. By green manure storage as silage, storage losses of N are lower than by composting. Also, a relatively high fertilizer value of silage N is achievable depending on the C/N ratio of the material. Nitrogen availability in green manure leys is higher after storage as silage compared to composting. Use of mobile green manures is mainly relevant in arable cropping systems without livestock where utilization of the roughage for animal feed or biogas production is impossible, as costs for ley/roughage harvest and transport can be relatively high. Our study showed that surface application of green manure silage...

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%.

Autores: Riemens, Marleen; Huiting, H.; Deru, Joachim; Schooten, H.A. van; Weide, R.
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.

ORGANIC POTATO CROPS ARE IMPROVED BY INOCULATING A MICROBIAL INOCULUM TO THE CUT SURFACE OF SEED TUBERS
Provedor de dados: 21
Autores: Xu, Hui-lian; Li, Fenglan; Su, Feifei; Qin, Feifei; Chang, Tingting.
Potato seed tubers are usually cut into blocks to reduce seed cost, break dormancy and induce dominance. In chemical farming, the cut surface is usually treated with fungicides to avoid infection. In the present research, the cut surface of the seed tuber blocks was treated with a microbial inoculum mixed into bamboo charcoal powder and dried for a moment. Inoculating and drying the cut trace of seed tuber blocks induced activation of the antioxidant enzymes SOD and POD. Properly drying the cut trace induced osmotic adjustment, leaf turgor improvement, disease resistance and yield increase in the potato crop. The treatments were more effective in the soil with compost applied onto the surface. The treatments with sterilized inoculum were more effective...

Autores: Montemurro, F.; Diacono, M.; Convertini, G; Vitti, C; Verrastro, V; Ceglie, F.G.; Erriquens, F.
Pratiche di agricoltura intensiva hanno condotto alla degradazione della risorsa suolo, vale a dire ne hanno diminuito la qualità. Più precisamente, la degradazione  riguarda la riduzione della sostanza organica, della stabilità strutturale e della disponibilità di nutrienti nel suolo, con conseguente decremento della produttività.  All’interno di un progetto di ricerca in corso, relativo a produzione e impiego di compost in agricoltura biologica, sono previste analisi di fitotossicità su sansa umida  denocciolata (SD) poi impiegata in una rotazione farro-cece. L’obiettivo della ricerca è quello di verificare come l’incorporazione al suolo di matrici organiche (M), anche tal quali, può concorrere a mantenere o incrementare la fertilità del suolo ed a...

Kansen voor pluimveemest in de gehele biologische productieketen
Provedor de dados: 21
Autores: Nauta, Wytze J.; Staps, J.J.M.
Deze brochure schetst de mogelijkheden voor verbetering van de afzet van pluimveemest in de biologische productieketen. Basis hiervoor vormt het project Kippenmest en Kringloop dat in de periode 2007 - 2011 door het Louis Bolk Instituut is uitgevoerd. Pluimveehouders in Nederland zijn vaak weinig grondgebonden. Daarom moet de mest worden afgevoerd. Afzet is echter niet altijd eenvoudig. Dit komt omdat de samenstelling van pluimveemest niet optimaal is. Vooral de relatief lage N/P- verhouding speelt een goede afzet naar de akker- en tuinbouw parten. Kansen voor Pluimveemest toont dat er goede mogelijkheden zijn om tot een gunstiger N/P-verhouding te komen via de voersamenstelling. Ook via andere wegen kan de afzet van pluimveemest worden verbeterd. Dat kan...

Distinct Nitrogen Provisioning From Organic Amendments in Soil as Influenced by Farming System and Water Regime
Provedor de dados: 21
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. A plant nutrition experiment using 15N labeled lupine as a fertilizer (green manure)...

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.

It is well-known that compost and manure applications to all kinds of soils if these organic materials are mature and composted under favorable conditions result in improved soil fertility and crop production in terms of yield and quality, but because manure is expensive in our region and the application of in-farm production compost for organic lands and farms of Turkey is limited, there is a great and urgent need for demonstrate compost using advantages to soil fertility, plant yield-quality and food safety (Kir 2006). Vegetables account for only approximately 2% of total organic production in Turkey, but there is great potential for growth of organic production for both export and domestic consumption of organic products in our country.

Entwicklung und Erprobung eines neuartigen, aus dem ökologischen Landbau stammenden stickstoffreichen Düngemittels für den ökologischen Gemüsebau
Provedor de dados: 21
Autores: Scheffler, Simon; Schmidtke, Knut.
Im ökologischen Gemüsebau werden hohe Nährstoffmengen benötigt, um qualitativ hochwertiges Gemüse zu produzieren. Der Nährstoffbedarf kann bisher nicht ausreichend durch ökologisch erzeugte Düngemittel gedeckt werden. Zum Einsatz kommen überwiegend organische Reststoffe aus der konventionellen Landwirtschaft. An dieser Stelle setzte das Forschungsvorhaben mit dem Ziel an, ein stickstoffreiches Düngemittel aus Futterleguminosenschnittgut für den ökologischen Gemüsebau zu entwickeln und in Spinat und Rote Rübe zu erproben. Es sollte junges Schnittgut mit einem C/N-Verhältnis von ≤ 10 geerntet werden, welches nach Einarbeitung in den Boden schnell mineralisiert.  Die Untersuchungen gliederten sich in vier Teile. Im ersten Teil der Arbeit wurden in...

Decomposition study using tea bags
Provedor de dados: 21
Autores: Tresch, Simon; Fliessbach, Andreas.
Comparing the decomposition of green tea as a fast -decomposing material with rooibos as a material, which is difficult to break down, allows for the calculation of the tea bag index. This provides information on the capability of the soil as a living organism to transform organic residues back into plant-available nutrients and make some contribution to the build-up of soil humus. This technique is easy to apply. Place the tea bag in the soil and take it out after three months to see how much is left. It is fascinating to discover the result of our hard working little helpers in the soil and how this work is giving nutrients to a new generation of plants.

Radmyllning och kombisådd av flytande gödselmedel i ekologisk spannmålsodling
Provedor de dados: 21
Autores: Lundin, Gunnar.
En möjlighet att minska kostnaderna för inköpt växtnäring inom den ekologiska odlingen är att minska förädlingsgraden beträffande gödselmedlens torkning och granulering. Exempel på sådana produkter är olika typer av flytande gödselmedel, bl.a. vinass.   Inom konventionell odling medför radmyllning och i ännu högre grad kombisådd  ökat utnyttjande av konstgödselns växtnäringsinnehåll. Fördelarna kan förväntas vara ännu större för vinass vars kväve huvudsakligen är organiskt bundet. Förutom de direkta effekterna på grödan torde de angivna metoderna även ha hämmande inverkan på mängden fröogräs.   Projektet syftar till att undersöka radmyllningens respektive kombisåddens potential för tillförsel av flytande växtnäring inom ekologisk spannmålsodling.   Vid...

Interactions Between Beneficial and Harmful Microorganisms: From the Composting Process to Compost Application
Provedor de dados: 21
Autores: Fuchs, Jacques G.
Numerous microorganisms are involved in the composting process, but their precise roles are often unknown. Compost microorganisms are influenced by the composition of the substrate and by the temperature in the compost pile. In addition, different microorganisms also influence each other, e.g. through competition. In the first phase of composting, microbial activity increase drastically, leading to a rise in temperature. The initial bacterial dominance is replaced by a fungal one during compost maturation.  (c) Springer Verlag, Berlin Heidelberg

The Danish organic crop rotation experiment for cereal production 1997-2004
Provedor de dados: 21
Autores: Rasmussen, Ilse A.; Askegaard, Margrethe; Olesen, Jørgen E.
In 1997 a crop rotation experiment was initiated at three sites in Denmark. The objective of the experiment was to explore the possibilities for both short-term and long-term increases in organic cereal production through manipulation of crop rotation design on different soil types. The experiment included three factors (proportion of grass-clover in the rotation, catch crops and manure application) in a randomised factorial design. The main indicators measured in the experiment were crop yield, nutrient leaching and weeds.    The crop rotation experiment has shown significant effects of location, crop rotation, catch crops and manure on yields, weed infestation, soil fertility and nutrient losses (Olesen et al., 2002; Schjønning et al., 2004; Askegaard et...

Improving N efficiency in barley through green manure management and biogas slurry
Provedor de dados: 21
Autores: Frøseth, Randi Berland; Bakken, Anne Kjersti; Bleken, Marina Azzaroli; Riley, Hugh; Thorup-Kristensen, Kristian; Hansen, Sissel.
In cereal production on stockless organic farms, green manure (GM) is commonly used to improve soil fertility. The clover-grass swards are mown frequently and the herbage is commonly mulched. The purpose of this study was to increase knowledge of the N-dynamics in such rotations, in order to suggest methods for improving N efficiency and thus organic cereal yields. The hypothesis was that spring application of biogas residue from anaerobic digestion of GM herbage increases the N uptake and yield of a subsequent barley crop, compared with repeatedly in situ mulching of the same GM herbage in the preceding season.  The effect of various GM treatments on spring barley yields and nitrogen dynamics was investigated, at four sites differing in soil and climatic...

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.

Eines der Probleme des Ökologischen Gemüsebaus ist die adäquate Versorgung der Kulturen mit Stickstoff. Bei dem Umgang mit der Stickstoffdüngung kann man mehrere Problemfelder unterscheiden:  - eine ausreichende N-Versorgung bei anspruchsvollen Kulturen  - die sachgerechte Kalkulation der N-Düngung in Abhängigkeit vom Bedarf der Pflanze  - mögliche N-min Rest am Ende der Kultur im Boden  Bei der Evaluierung der Kalkulation zeigte sich, daß die Beziehung zwischen dem Ertrag und dem kalkulierten N-Angebot bei Kohl und Spinat eng war. Es zeigte sich außerdem, daß die Nachlieferung aus der Gründüngung in der Regel überschätzt worden war, während die aus dem Humus in der Regel unterschätzt worden war. Außerdem zeigte sich, dass es erforderlich ist, weitere...

Earthworms are one of the most important soil macrofaunal groups, and they play a major role in agricultural ecosystems. Agricultural practices, such as reduced tillage, the use of green manures and organic fertilization, can be beneficial for earthworm populations in agricultural systems. However, under a Mediterranean climate, not much is known regarding their response to agricultural management. The aim of this study was to analyse the effects of tillage type, organic fertilization, and green manures on the density and biomass of earthworms in organic arable dryland. The trial was conducted in a four-year crop rotation with a complete factorial design that combined tillage system (mouldboard ploughing vs. chisel), fertilization (composted farmyard...

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.

Phosphorus (P) should be recycled from organic wastes as much as possible, and input is needed in stockless organic agriculture. Here we assessed 7 organic residues and compared them to mineral P fertilizer and rock phosphate as fertilizer for barley. P availability in the mixtures and residual P availability were also assessed by DGT. The best availability was found in digested liquid manure followed by wood ash, fish sludge, composted solid manure and composted food waste. Meat and bone meal, the commercially available product ladybug and rock phosphate had low P availability at the same level as no P. Only wood ash had significant P available for the next crop. The pH level of the soil did not affect P availability for any of the P sources. DGT...

These proce-dures are distinctly improved by including the mineral soil nitrogen the legumes can use during the growing season. A system monitoring the plant available soil N was established in 2005 and 2006, which was distributed across Germany. Available soil N was assessed by means of non leguminous reference plants. Results from 2005 are recorded. It is the objective to make the calculation of the N balance of legumes inter-actively available in the near future via the internet portal ISIP (Informationssystem Integrierte Pflanzenproduktion). The target group are agricultural consulting services and...

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...

Autores: Starz, Walter.
Gülle, ein Gemisch aus Kot, Harn, Futter- und Einstreuresten, ist ein flüssiger Wirtschaftsdünger, der in der Biologischen Landwirtschaft anhaltenden Diskussionsstoff liefert. Gülleflora und Humuszehrung sind nur zwei Worte, die in Verbindung mit diesem Wirtschaftsdünger gebracht werden. Was ist aber nun dran am Einsatz der Gülle im Dauergrünland? Sind die Vorurteile berechtigt und hat sie den schlechten Ruf im Bio-Dauergrünland verdient? Diesen Fragen versucht diese ÖAG-Info nachzugehen und möchte das Thema Gülle in der biologischen Grünlandwirtschaft sachlich beleuchten und diskutieren.

Extractability of slurry and fertilizer phopshorus in soil after repeated freezing
Provedor de dados: 21
Autores: Soinne, Helena; Peltovuori, Tommi.
The potential effects of freezing on phosphorus (P) chemistry in Finnish soils are not well known. We studied the effects of multiple freeze-thaw cycles on soil P chemistry in a laboratory incubation experiment with one organic and one mineral surface soil. The soils were incubated at +5°C or at alternating +5/–20°C temperatures for 24 weeks, either without amendment or amended with pig slurry or with commercial compound fertilizer (NPK 20–3–9). After incubation, the soils were analyzed for water-soluble reactive and unreactive P, and acid ammonium acetate soluble P (PAAA). Freezing and thawing of soils during the incubation had no significant effect on any of the water-soluble P fractions or PAAA. The outcome was most likely a consequence of the good P...

Hoftor-Bilanz von Phosphor und Kalium in Öko-Milchviehbetrieben
Provedor de dados: 21
Autores: Leisen, Edmund.
Between April 2014 and March 2015 farm-gate balances of phosphorus and potassium have been calculated on 82 Organic Farms. Results as follow: An additional fertilization with phosphorus, at least on the long run, seems to be  necessary to adjust negative phosphorus balances. Potassium also often shows negative balances, especially when leaching losses are considered. However, as long as the K-contents in the plants are high, additional potassium fertilization is not  necessary, especially when aspects of animal nutrition are considered.

Soil mechanical behaviour of sandy loams in a temperate climate: case studies on long-term effects of fertilization and crop rotation.
Provedor de dados: 21
Autores: Munkholm, Lars J.; Schjønning, Per; Petersen, Carsten T.
Two case studies on Danish sandy loams investigated long-term effects of fertilization and crop rotation. Case Study 1 compared a diversely cropped organically farmed soil (DFG(1)) with a conventionally farmed soil predominantly growing annual crops (DFA), both receiving animal manure.  In Case Study 2, a diversely cropped organically managed soil DFG(2)) receiving animal manure was compared with an almost exclusively cereal cropped conventionally farmed soil receiving no animal manure (CCC). A multi-level experimental strategy was followed to compare integrating field methods with specialized laboratory methods. Ease of tillage was described in the field and characterized using a drop shatter field test and by measuring aggregate tensile strength. Fitness...

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...

Stickstoff-, Kalium- und Phosphorverluste während der Stallmistrotte in 11jährigen Freilandversuchen; Konsequenzen und Gegenmaßnahmen
Provedor de dados: 21
Autores: Raupp, Joachim; Oltmanns, Meike.
Die Reduzierung von Nährstoffverlusten während der Stallmistrotte auf ein tolerierbares, unvermeidliches Niveau ist nicht nur aus landwirtschaftlichen, sondern auch aus Umweltschutzgründen sinnvoll. Dies setzt voraus, die wesentlichen Einflußfaktoren und Prozesse zu kennen, bei denen es zu Verlusten kommen kann. Anhand von 14 Rotteversuchen mit Rindermist im Freiland in 11 Jahren wurden die Rottetemperatur gemessen, Verluste quantifiziert und mögliche Gegenmaßnahmen vorgeschlagen.

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.

Grüngutkompost und Gärsubstrate („Biogaskompost“) fällt in der Schweiz jährlich in grossen Mengen an. Befürchtungen, dass Kompost Stickstoff „fressen“ sowie Unkraut und Krankheiten verbreiten, verhindern oft einen gezielten Einsatz im Gemüsebau.  Versuche und Praxiserfahrungen der letzten Jahren haben aber gezeigt, dass Komposte bei der richtigen Herstellung und Verwendung eine vielfältig positive Wirkung haben können. Neben einer Düngerwirkung und einem humusaufbauenden Effekt können gute Komposte auch krankheitsunterdrückend wirken.

Autores: Arnault, mrs I; Vey, Mr F; Fleurance, M C; Nabil, Mrs H; Auger, Mr J.
Like Brassicaeae spp., Allium spp.have biofumigation properties attributed to sulfur components, mainly three disulfides: dimethyl disulfide (DMDS), dipropyl disulfide (DPDS); and diallyl disulfide (DADS), with an efficacy superior to that of DMDS. In this study, the biofumigant activity of Allium (onion and leek) by-products was investigated in vitro and in vivo. In vitro, the experimental model consisted of a host-pathogen system: cucumber-Pythium ultimum. The results of the bioassay show that cucumber plants in compost inoculated with the pathogen and containing onion or leek by-products show better vegetative growth than the control. In vivo, soil biodisinfection with onion by-products in asparagus leads to a yield intermediate between the untreated...

Autores: Bokhorst, J.G.; Janmaat, Leen.
Fosfaatmijnen zijn wereldwijd relatief dun gezaaid. Op termijn dreigt fosfaat een schaarse grondstof te worden. Om eventuele schaarste voor de landbouw in te kunnen schatten is meer inzicht nodig in fosfaatbeschikbaarheid in relatie tot de opname door de plant. Het is daarbij de vraag of de gebruikelijke bodemanalyse van fosfaat wel goed inzicht geeft in de beschikbaarheid. Biologische landbouw toont aan dat dat niet het geval is.

Effects of anaerobic digestion of organic manures on N turnover and N utilization
Provedor de dados: 21
Autores: Sørensen, Peter; Khan, A R; Møller, Henrik B.; Thomsen, Ingrid Kaag.
Animal manures and plant-based manures are used for biogas production by anaerobic digestion (AD). After AD the concentration of ammonium-N in manure is increased and the concentration of decomposable C is decreased. Thus, the potential first year fertilizer value of the manure can be increased by the treatment. However, pH is also increased by AD thereby increasing the risk of ammonia losses. The objective of this paper was to compare N turnover in soil after application of digested and corresponding undigested manures, and to compare N fertilizer values of digested manures after direct injection or surface-banding in cereals.   After AD of pig and cattle slurry the increase in potential plant availability was equivalent to 10-25% of total manure N. AD of...

Welchen organischen Handelsdünger für den ökologischen Gemüsebau? [Which organic fertilizer for organic horticulture?]
Provedor de dados: 21
Autores: Laber, H.
Welcher der organischen Handelsdünger für den ökologischen Gemüsebau ist der beste? Und welche Rolle spielt die Aufbereitung der Düngemittel? Zur Beantwortung dieser Frage wurden seit Beginn der 90er Jahre im deutschsprachigen Raum über 30 Versuche angelegt, bei denen die verschiedenen organischen Handelsdünger miteinander verglichen wurden. Nach den vorliegenden Versuchsergebnissen erwiesen sich Rizinusschrot, die Horn- und Haarmehlprodukte und auch Blutmehl als gleich wirksame Düngemittel. Auch Maltaflor zeigte vergleichbare Resultate. Mit dem sehr preisgünstig zu beziehenden Rapsextraktionsschrot und den  Leguminosenschroten konnten zumeist akzeptable Ergebnisse erzielt werden. Den Ursachen für die bisweilen gefundenen höheren Ertragseinbußen bei diesen...

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....

Two phase continuous digestion of solid manure on-farm: design, mass and nutrient balance
Provedor de dados: 21
Autores: Schäfer, Winfried; Evers, Lars; Lehto, Marja; Sorvala, Sanna; Teye, Frederick; Granstedt, Artur.
During the last decade some so called ‘dry fermentation’ prototype plants were developed for anaerobic digestion of organic material containing 15-50 % total solids. These plants show added advantages com-pared to slurry digestion plants: Less reactor volume, less process energy, less transport capacity, less odour emissions. However on-farm dry fermentation plants are not common and rarely commercially available. This paper reports about an innovative two phase prototype biogas plant designed for continuous digestion of solid dairy cattle manure.

Autores: Mattila, Pasi K.
Volatilization of ammonia (NH3) from animal manure is a major pathway for nitrogen (N) losses that cause eutrophication, acidification, and other environmental hazards. In this study, the effect of alternative techniques of manure treatment (aeration, separation, addition of peat) and application (broadcast spreading, band spreading, injection, incorporation by harrowing) on NH3 emissions in the field and N uptake by ley or cereals was studied. The effect of a mixture of slurry and peat on soil properties was also investigated. The aim of this study was to find ways to improve the utilization of manure N and reduce its release to the environment. Injection into the soil or incorporation by harrowing clearly reduced NH3 volatilization from slurry more than...

In organic farming rock phosphate is used as a mineral P fertilizer, although the agronomic efficiency is limted. The objective of this study was to investigate in field and pot experiments the mobilization of rock phosphate by P-efficient plants (white lupin and faba bean) and the P availability for P-inefficient plants (spinach and maize) during a crop rotation in 2002/2003 and 2003/2004. The P uptake of spinach was higher in a crop rotation with white lupin and faba bean than in a crop rotation with summer wheat. In pot experiments the application of new basic slag phosphate (CaHPO4) resulted to a higher P uptake of the plants than rock phosphate.

Abschätzung der N-Freisetzung aus unterschiedlich bewirtschafteten Klee-, Kleegras- und Luzernebeständen im Verlauf nachfolgender Weißkohlkulturen und im zweiten Jahr nach Umbruch
Provedor de dados: 21
Autores: Laber, Hermann.
Mehrjährige Leguminosen(gras)bestände sind ein wesentliches Fruchtfolgeglied im ökologischen Landbau. Zur N-Fixierungsleistung und den N-Mengen in Aufwuchs und Wurzeln solcher Bestände liegen umfangreiche Literaturdaten vor, dagegen wurde die N-Freisetzung nach Umbruch dieser Bestände in situ bisher kaum untersucht.  Ziel der über 3 Vegetationsperioden laufenden Untersuchung war es, die N-Freisetzung aus unterschiedlich bewirtschafteten Klee-, Kleegras- und Luzernebeständen (ein- bzw. 2-jährig, Futternutzung bzw. Grünbrache) bei Herbst- bzw. Frühjahrsumbruch zu untersuchen und diese Ergebnisse in ein einfaches Düngungs-Kalkulationsprogramm einfließen zu lassen.  Dazu wurde nach dem Umbruch Lagerweißkohl angebaut. Als Kontrolle dienten Parzellen, die...

Nitrogen mineralization and greenhouse gas emissions after soil incorporation of ensiled and composted grass-clover as green manure
Provedor de dados: 21
Autores: Carter, Mette S.; Sørensen, Peter; Petersen, Søren O.; Ambus, Per.
This 3-month incubation study showed that ensiled grass-clover was a better nitrogen (N) source than a composted grass-clover and straw mix (grass-clover:straw, 4:1, w:w), owing to the high content of labile compounds compared to the more degraded compost. Our study also indicated that emissions of the strong greenhouse gas nitrous oxide (N2O) can be reduced by incorporating green manure using harrowing instead of ploughing. The silage-derived N release by the end of the incubation was equivalent to 38-42 kg N ha-1, which corresponded to one third of the N applied in silage, with no difference between ploughing and harrowing. In contrast, no net release of mineral N was detected from the composted grass-clover.

Ein zweifaktorieller Feldversuch (Gärrestdüngung und Fruchtfolge) zur Untersuchung von Fruchtfolgen für die Biogasproduktion wird seit 2004/2005 in Viehhausen bei Freising durchgeführt. Die Düngung mit Biogasgärrest führte zu signifikant höheren Weizenerträgen gegenüber den ungedüngten Parzellen. Die höchsten Weizenerträge wurden in der Fruchtfolge mit dem höchsten Kleeanteil erreicht. Die Steigerung der Weizenerträge zeigt, dass Synergieeffekte zwischen Energie- und Nahrungsmittelproduktion möglich sind.

N-Minieralisierung organischer Handelsdünger und ihr Effekt auf den Ertrag von Kopfsalat und Blumenkohl im Frühjahr
Provedor de dados: 21
Autores: Koller, Martin; Peter, Markus; Berner, Alfred.
Die ersten Gemüsejungpflanzen werden im Schweizerischen Mittelland Ende Februar ins Freiland gesetzt. In den kalten Böden wird zu dieser Zeit nur wenig Stickstoff mineralisiert. Deshalb werden die Gemüsekulturen in der Regel mit organischen Handelsdüngern versorgt, die relativ leicht mineralisierbaren Stickstoff enthalten. Zurzeit sind in der Schweiz 22 stickstoffreiche Handelsdünger für den biologischen Landbau zugelassen (Wyss et al. 1998), die sich in ihrer Zusammensetzung und Aufbereitungsform (gemahlen, pelletiert) unterscheiden.  In drei Feldversuchen prüften wir verschiedene organische Handelsdünger auf ihre N-Mineralisierungsgeschwindigkeit und den Ertrag von Kopfsalat und Blumenkohl. Des weiteren werden die Ergebnisse aus einem Laborbrutversuch...

Autores: Kádár, Zsófia; Christensen , Anne Deen; Oleskowicz-Popiel, Piotr; Heiske, Stefan; Thomsen , Mette Hedegaard; Schmidt, Jens Ejbye.
Organic agriculture is one sustainable alternative to avoid negative environmental effects often caused by conventional agriculture. The area for organic farming in Europe is increased rapidly in the last decades and Denmark is one of the top-ten countries in Europe as regards the organic share of the total cultivated area.  The production of bioenergy from local biological resources and the maintenance of soil fertility seem to have been opposing aims in organic agriculture. In organic farming, there is a strong effort to reduce the reliance on fossil fuels and decrease greenhouse gas emissions in organic agriculture.   Cheese whey is a by-product from the dairy industry, which has the highest market share of organic foods in Denmark. It generates...

Contribution of nitrification and denitrification to N2O emissions from urine patches
Provedor de dados: 21
Autores: Carter, Mette S.
Urine deposition by grazing livestock causes an immediate increase in nitrous oxide (N2O) emissions, but the responsible mechanisms are not well understood. A nitrogen-15 (15N) labelling study was conducted in an organic grass-clover sward to examine the initial effect of urine on the rates and N2O loss ratio of nitrification (i.e. moles of N2O-N produced per moles of nitrate produced) and denitrification (i.e. moles of N2O produced per moles of N2O + N2 produced). The effect of artificial urine (52.9 g N m-2) and ammonium solution (52.9 g N m-2) was examined in separate experiments at 45 and 35% water-filled pore space (WFPS), respectively, and in each experiment a water control was included. The N2O loss derived from nitrification or denitrification was...

Reihenapplikation von Komposten zur Kontrolle bodenbürtiger Krankheiten – technische Lösungen für Kartoffeln und Leguminosen
Provedor de dados: 21
Autores: Bohne, Björn; Hensel, Oliver; Bruns, Christian.
In principal suppressive effects with composts on soilborne diseases are well known. In practise, however, a targeted utilisation is not common due to technical constraints. The more precise composts are applied at the site of action the more effective they are as shown in potatoes to control Rhizoctonia solani with a strip application of composts compared to broadcast application. Similar effects were achieved in peas. Therefore, dosage tools were developed for the use in potato planting machines and sowing machines for grain legumes. It was shown with defined composts (yard waste composts with size fraction &lt;10 mm, 30-40  % humidity) that the developed tools will provide exact longitudinal and lateral application.

Während Dünger auf Basis von Phosphatgestein einen hohen abiotischen Ressourcenverbrauch bewirken, zeigen aufbereitete P-Recyclingdünger in Allgemeinen einen hohen Primärenergieverbrauch und relativ hohes Eutrophierungspotenzial. Kompost kann sehr ungünstige Ergebnisse beim Treibhaus-, dem Versauerungs- und dem Eutrophierungspotenzial aufweisen. Klärschlamm und dessen Aufbereitungsprodukte wie Asche oder Thomasphosphat-ähnliche P-Düngemittel zeigen zwar deutlich günstigere LCA Ergebnisse, sind aber problematisch hinsichtlich der P-Pflanzenverfügbarkeit oder einer Schadstoffanreicherung.

Climate change causes droughts, which in turn cause significant physiological stress for soil microorganisms. In this study, we investigated how the abundance of total bacterial, crenarchaeal and fungal communities and the abundance of N-cycling microbial guilds responded to a severe agricultural drought event in a long-term experiment of minimum tillage (MT) and conventional ploughing (CT) at two soil depths.  This study was financially supported by the European Commission within the EcoFINDERS project (FP7-264465), CORE Organic Plus funding bodies within the FertilCrop project, and by the Slovenian Research Agency within the programme P4-0085.

The cultivation of grain legumes is important for sustaining nitrogen availability in organic farming systems, but poses problems with weed suppression and plant diseases. To improve soil conditions and nutrient availability for growing grain legumes in organic farming, green chop, horse manure and vegetable compost were applied to faba beans in a field test in 2009 and 2010. Equivalent yield performance after application of these organic fertilizers to faba beans was found compared to the control (without fertilization) and higher yields of the follower crop, winter wheat, resulted. After applying green chop, a strong suppressive effect on the growth of annual weeds was observed.

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...

Assessment of Alternative Phosphorus Fertilizers for Organic Farming: Meat and Bone Meal
Provedor de dados: 21
Autores: Möller, Kurt.
In the past meat and bone meal was a major source of nutrients for recycling back to agricultural land, either as animal feed or organic nitrogen and phosphorus fertilizer. Nowadays - since the Bovine Spongiform Encephalopathy (BSE) crisis in 1999 - it is mainly used as fertilizer. Although meat and bone meals are allowed by EU regulation in organic farming, several growers’ organisations prohibited them since the BSE crisis. Incineration or melting in a cupola furnace are alternative treatment options to their direct use eliminating any risk on BSE transmission. However, these processes lead to losses of organic matter as well as nitrogen and sulfur and affect the phosphorus availability. The fact sheet shows which actions are needed to ease the statutory...

Assessing quality of plant raising media for organic systems
Provedor de dados: 21
Autores: Little, Tony; Morris, Cath; Clarke, Aldwyn.
Good quality transplants are vital to growers for a number of reasons. Their ability to better tolerate pest, disease and weed problems and their capacity to make better use of newly incorporated green manures (compared to direct drilling) make them all the more so in organic systems. The availability of high quality growing media is essential to producing healthy vigorous plants, but the organic standards restrict the choice of products available and many growers do not feel they have sufficient information to base their choices. OCW, with support from Farming Connect, coordinated a project to assess the certified products and looked at a green waste based product under development to help address this problem.

Im Anhang I der Durchführungsverordnung (EG) Nr. 889/2008 zur EG-Öko-Verordnung (EG Nr. 834/2007) sind die im ökologischen Landbau zugelassenen Düngemittel sowie Natur- und Hilfsstoffe gelistet. Durch die Ausweitung des Marktes für ökologisch erzeugte Produkte nimmt die Spezialisierung der Betriebe weiter zu. Intensiv wirtschaftende Ökobetriebe, insbesondere Gemüseanbauer und viehlose Marktfruchtbetriebe, sind auf die Zufuhr von externen Nährstoffen angewiesen, da große Nährstoffmengen mit den Ernteprodukten exportiert werden und Wirtschaftsdünger oft nicht in hinreichender Menge zur Verfügung stehen.

Soil fertility - manure treatment
Provedor de dados: 21
Autores: Berner, Alfred; Messerli, Niklaus.
Well-treated manure is crucial for good soil fertility. However, the treatment requires effort that not all farmers are willing to make. The leaflet first lists some reasons why it is worth the effort. There is a short overview of different types of manure and of how they are formed. Additionally, their advantages and disadvantages are listed.   The leaflet also contains a theoretical part about the stages in the composting process.  Finally, there is a list of tips for treating manure on a farm. The information helps making rotted manure or manure compost.   The leaflet might be interesting for all farmers who want to start or improve manure treatment. It can be used by organic and conventional farmers.

Autores: Koller, Martin; Schmid, Michael; Brankatschk, Kerstin; Friedel, Jürgen K.; Sessitsch, Angela.
Durch den Ausbruch von EHEC-Keimen in Norddeutschland ist das Potential von krankheitsauslösenden Keimen aus Gemüsepflanzen ins Bewusstsein geraten. In dem transnationalen, mehrjährigen Projekt „PathOrganic“ wurden mögliche Übertragungswege dieser und anderer pathogener Bakterien von Mist und Gülle zum verkaufsfähigen Gemüse untersucht. In Gülle- und Mistproben sowie auf erntereifem Gemüse wurden Keime gefunden. Grundsätzlich besteht ein erhöhtes Gesundheitsrisiko, wenn zu kurz nach dem Ausbringen von Mist oder Gülle Gemüse gepflanzt wird und in der Kette bis zum Konsumenten gute Wachstumsbedingungen für die Keime auftreten, wie etwa bei geschnittenem, in Schutzatmosphäre abgepacktem Gemüse.

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...

Vihmaussidel on oluline roll mullaviljakuse kujunemisel. Nende elutegevuse tagajärjel paraneb orgaanilise aine mineralisatsioon ja lagunemine. Vihmausse peetakse  keskkonna hindamise oluliseks vahendiks tänu pidevale kontaktile mullaga, mulla vee ja selles lahustunud sooladega (Ivask, 1996). Vihmaussikoosluste ja struktuuri põhjal saab teha järeldusi põllumajandusliku tegevuse mõjust muldadele. Liikide arv, biomass ja koosluse ökoloogiline struktuur on põllumajanduslikes muldades üks olulisemaid parameetreid, määramaks mulla saastatust ja olukorda (Paoletti, 1999). Vihmausside aktiivsus ja biomass sõltub oluliselt majandamisviisist ning seeläbi mullaharimisest, orgaaniliste või mineraalsete väetiste lisamisest ning mulda viidava orgaanilise aine kogusest....

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.

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...

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.

Nedfældet kvælstof skal placeres tæt ved afgrøden
Provedor de dados: 21
Autores: Petersen, Jens.
Konkurrence mellem afgrøde og ukrudt begynder allerede ved tilførsel af gødning. Direkte nedfældning af gødningen kan, i forhold til jævn indarbejdning i jorden, øge afgrødens optagelse af gødningskvælstof samtidig med, at ukrudtets optagelse af gødningskvælstof reduceres. Det er imidlertid en forudsætning, at gødningsstrengen placeres tæt på kornrækken. Dog bør alle kornrækker sikres lige adgang til gødningen. Ud fra en ren næringsstofsynsvinkel er der ikke den store forskel på, om det er gylle eller handelsgødning, der placeres. Placering af gødning foretages almindeligvis kun i forbindelse med såning af vårsæd, men der er også effekt af gødningsplacering i etablerede afgrøder. Der er dog væsentlige praktiske udfordringer forbundet med både placering af...

A surplus benefit from this praxis may be the suppressing of propagules from harmful biological pest like animal parasites, pathogens, and weed seeds. In the BIOCONCENS project (http://www.icrofs.dk/Sider/Forskning/foejoIII_bioconcens.html) batch experiments were performed, where survival of six species of weeds and the pigs large roundworm Ascaris suum (non-embryonated eggs) was assessed under conditions similar to biogas plants managed at meso- (37°C) and thermophilic (50°C)...

Phosphor und Kalium im ökologischen Landbau – aktuelle Probleme, Herausforderungen, Düngungsstrategien

Über die augenblickliche Situation und Entwicklungstendenzen der Nährstoffversorgung auf den Ökobetrieben liegen keine umfassenden Erkenntnisse vor. Nach Untersuchungen in Sachsen bzw. Sachsen-Anhalt wird nur eine sehr geringe Anzahl der Bodengehalte an Phosphor (P) und Kalium (K) der Ackerflächen in die VDLUFA-Versorgungsklasse A eingestuft und aus den hohen Anteilen an den Versorgungsstufen C – E kann ein relativ gutes Versorgungsniveau abgeleitet werden. Aus flächenbezogenen Nährstoffbilanzierungen der Ökobetriebe gehen im Durchschnitt jedoch negative P- und K-Salden hervor. Im Laufe der Zeit haben sich deutlich unterschiedliche Vorstellungen zur Grunddüngung und Bodenuntersuchung im Ökolandbau entwickelt, die kurz angesprochen werden:   - Auf Grund der...

Provedor de dados: 21
Autores: Raupp, Dr Joachim.
Nutrient budgets are an important tool of farm planning. Normally the amounts of manure, feedstuffs, yields etc. as well as their nutrient contents are measured and analysed in each single case. If this is impossible for labour reasons, standard data sets of nutrient contents in agricultural products have to be used. However, these data sets have been determined in conventional farming. Thus, the question arises, whether theses results can be transferred to organically grown crops. This question was investigated with rye samples of a long-term trial with farmyard manure and mineral fertilization.     In many cases the N, P and K contents in organically and minerally fertilized samples differed significantly, though one of the treatments did not always show...

Assessment of Alternative Phosphorus Fertilizers for Organic Farming: Compost and Digestates from Urban Organic Wastes
Provedor de dados: 21
Autores: Möller, Kurt.
Organic wastes from urban areas include organic household wastes, food processing residues and catering wastes. These so called "Urban Organic Wastes" are important potential sources for nutrient recycling back to agriculture. Main waste treatment options for these sources are composting and anaerobic digestion. Both differ in the process performance – regarding for example emissions or energy balances – and in the characteristics of the final fertilizer pro­duct. This fact sheet describes the most important aspects of compost and digestates from urban organic wastes for use in organic farming.

Nitrogen fertilizer value of digestates from anaerobic digestion of animal manures and crops
Provedor de dados: 21
Autores: Sørensen, Peter; Mejnertsen, Peter; Møller, Henrik B.
After anaerobic digestion (AD) of manures for biogas production the concentration of ammonium-N is increased and the concentration of decomposable carbon in manure is decreased. That implies that the first year fertilizer value of the manure can be increased by the treatment. However, pH is also increased by AD thereby increasing the risk of ammonia losses while the lowered dry matter content on the other hand improves the manure infiltration in soil and reduces the risk of ammonia loss. Therefore the effects of AD on plant N availability can be expected to interact with the manure application method used.   In stockless organic farming it has been suggested that nitrogen utilization can be improved by using anaerobic digestion of plant-based green...

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...

Nutrient turnover and losses during composting of farmyard manure. Results of outdoor experiments over 11 years
Provedor de dados: 21
Autores: Raupp, Joachim; Oltmanns, Meike.
This paper tries to quantify losses of dry matter and nutrients and to look for parameters relevant to the risk of losses. We used data from 14 outdoor experiments carried out in 11 years with cattle manure. Nitrogen (N) rich manures seem to be predestined to have high dry matter and N losses during com-posting. In cases of high temperatures in the thermophilic stage we also observed also high dry matter losses, but not necessaryly high N losses. This may be a hint that an intensive decomposition of or-ganic matter is combined with a strong heat development. However, temperature level was independ-ent from the original N content. K losses were not correlated with any of the investigated parameters, not even with water content. Composted manure was about...

Autores: Perälä, Paula; Kapuinen, Petri; Esala, Martti; Tyynelä, Sanna; Regina, Kristiina.
The effect of different fertilizer application techniques on nitrous oxide and methane emissions were investigated in a field experiment. Gas fluxes were measured during a five months period in 2001 from a barley field located in Vihti, southern Finland. The effects of different fertilizer application techniques on crop yield and quality were also investigated. According to the results, slurry injection produced the most N2O during the measurement period. Placement of mineral fertilizer produced least N2O. Methane fluxes were close to zero and there were no statistically significant differences between the treatments.

This leaflet will help organic farmers to overcome barriers and get started with on-farm composting. With minimal additional work, vegetable and arable farmers can upgrade crop residues to compost. Compost application can be integrated in the crop rotation and combined with reduced tillage. Also on livestock farms composting can offer added value. Composted manure is more stable, because the decomposition process has already partly taken place. By mixing other materials in the manure, the N/P ratio in the compost can be adjusted. Moreover, composting kills off the pathogens in manure. This leaflet gives an overview of the characteristics of good quality compost and the different steps of making compost.

Autores: Goodlass, G; Hatch, D J; Shepherd, M A; King, J A; Cuttle, S P; Roderick, S; Briggs, S.
Optimising the amount of nitrogen captured by fertility building crops is essential for successful organic farming. This study used a combination of literature review, empirical measurements, model development and farmer participation to produce improved guidelines on making the most of soil nitrogen for organic farmers and growers. The main field experiment examined the impact of cutting and mulching on the build up of soil nitrogen. Recommendations to organic farmers from this part of the work, are that cutting and removing herbage during the fertility building phase promotes the highest amount of nitrogen fixation. However the highest soil residues occurred when clover was mulched in situ. Application of organic manures to legumes should also be avoided...

Autores: Sanchez de Cima, Diego; Tein, Berit; Eremeev, Viacheslav; Luik, Anne; Kauer, Karin; Reintam, Endla; Kahu, Greete.
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...

Autores: Beji, Sadreddine.
Le présent travail a étudié l’effet de la fertilisation organique à base de farine de poisson sur trois types de tomates conduites selon le mode biologique. L’essai s’est déroulé sous serre Delta 9 dans la région d’Agadir au sud ouest du Maroc. Trois doses de farine de poisson (73 g /plante, 110 g /plante et 140 g /plante qui représentent 170 kg d’azote par hectare, 255 N/ha et 360 N/ha) ont été appliquées sur trois types de tomates (grappe, ronde et cerise). Les résultats obtenus ont montré que la farine de poisson contribue à l’amélioration de la fertilité du sol notamment pour ce qui est de la teneur du sol en matière organique qui est passée de 0.64% avant l’installation de la culture à 1.32% après la récolte du 8ème bouquet, le taux des nitrates qui a...

Autores: Leisen, Edmund.
Most of the dairy farms have not applied purchased fertilisers since they changed to Organic farming. In this study it has been investigated, whether the plant nutrients in the soil have been decreased or increased during a period of 14 to 15 years. The studies have been made in Northern Germany. The P-contents in the plants remained constant, although the soil contents decreased. Within silages the K-contents increased and the Mg-contents remained unchanged. The purchase of fertilisers is not required in most cases, it is even unwanted in the case of potassium.

Mit Nährstoffbilanzberechnungen lassen sich Umweltleistungen im Bereich des Nährstoffeinsatzes in der Landwirtschaft aufzeigen. In der Schweiz ist die Erfüllung einer ausgeglichenen Bilanz Voraussetzung für staatliche Subventionen im Rahmen von Ökoprogrammen. Auf den Biobetrieben wird zur Nährstoffbilanzberechnung seit langem die sogenannte DGVE-Methode (Gemüsebau: LBL-Methode), auf integriert produzierenden Betrieben die sogenannte LBL-Methode eingesetzt (Tab.1). Von der staatlichen Biokontrolle wurde zunehmend eine einheitliche, für alle Betriebstypen einsetzbare Methode verlangt. Anhand von Praxisdaten sollten daher die oben genannten Methoden auf ihre Vergleichbarkeit überprüft werden. Um die Salden besser bewerten zu können, wurden sie mit den in...

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...

Effects of soil, root mycorrhization, organic and phosphate fertilization, in organic lettuce production
Provedor de dados: 21
Autores: Brito, L Miguel; Sampaio, Áurea; Pinto, Rui; Mourão, Isabel; Coutinho, João.
The influence of organic and phosphate fertilization, and root mycorrhization, in organic lettuce production, was assessed with factorial treatment combinations of: soil type (SOP – soil from organic and SCP – soil from conventional production) and organic fertilizer (0, 2 and 4 t ha-1) in the first trial; mycorrhizal inoculation (mycorrhized and non-mycorrhized plants) and Gafsa phosphate (0, 100 and 200 kg P2O5 ha-1) in the second. Lettuce yield decreased in the SCP with the application of increasing rates of organic fertilizer due to the very high electrical conductivity (50.1 dS m-1) and lack of maturation of this fertilizer. However, the harmful effects of the organic fertilizer were minimized in the SOP. The application of increasing rates of Gafsa...

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...

Autores: Mattila, Pasi K.
The effectiveness of peat manure, manufactured of pig slurry and moderately humified Sphagnum peat (slurry:peat ca. 1:1.5 v/v), as nitrogen (N) source for spring barley was investigated in a four.year field experiment on a clay loam soil in south-western Finland. Pig slurry, NPK fertilizer and plain peat were used as references. Manures were incorporated before sowing or surface-applied after sowing in spring at an ammoniacal N rate of.54.106 kg.ha-1 with or without supplementary NPK fertilizer (40.kg N.ha-1). Soil moisture conditions were varied by different irrigation treatments. Peat manure produced 5.15% higher grain yields than pig slurry, with the largest difference after surface application. Incorporation was more important for slurry than for peat...

Opportunities and limitations in use of clovers as N-source in organic farming systems in Norway
Provedor de dados: 21
Autores: Sturite, I.
From an economic as well as ecological point of view, transfer of clover N to the subsequent growing season should be maximised and the risk of environmental pollution minimised. It is very important in organic farming. Detailed studies on white clover lifespan indicated that the foliage is a main source of readily plant-available N as the leaves are short lived. However, the leaf N is largely lost from the plant foliage during the cold season. The risk of loss may probably be reduced by using winter-hardy cultivars that tend to reallocate resources to stolons and roots which are more persistent than leaves.

Repeated clover subcropping as a strategy for commercial organic grain production
Provedor de dados: 21
There is a shortage of organic grains, and  a need to develop organic production systems which ensure high and stable grain yields. Commercial organic grain production is mainly a task for farms with few or no livestock, and the development of well functioning strategies for nutrient supply and weed control in commercial organic cereal production under such conditions, is a considerable scientific challenge. The nutrient losses should be minimized and grain yields maintained at economically satisfactory levels over time. A promising strategy involves undersowing of clover in grains where yields can be taken and nitrogen (N) be supplied simultaneously. The main objective of this project was to evaluate if repeated undersowing of clover is a well functioning...

Air capacity, the easily available water and buffering capacity were also within acceptable recommended values for horticultural substrates. With increased composting time the physical characteristics of the composts improved, but the same was not true for chemical characteristics. It is recommended to use these acacia composts in mixtures with peat which increases the content of organic matter and the C/N ratio, and decreases the pH and the electrical conductivity, of the final...

Der er gennemført undersøgelser af N udnyttelse og N tab ved anvendelse af komposteret eller ensileret mobil grøngødning bestående af kløvergræs eller lucerne.    Ensilering af mobil grøngødning anbefales frem for kompostering som følge af høje N-tab og lavere kvælstofvirkning ved kompostering.   Gødningsværdien af grøngødning i vårbyg varierede (17-48%), men kunne forudsiges udfra tørstof/protein og C/N forholdet. Samme virkning af nedpløjet og nedharvet ensilage. Risiko for svidning ved udbringning af ensilage direkte på afgrøde.   Omkostninger til høst og transport bør vurderes under de aktuelle omstændigheder

Parameters for apple quality - 2 - and the development of the ‘inner quality concept’ 2001-2003
Provedor de dados: 21
Autores: Bloksma, Joke; Huber, Machteld; Northolt, Martin; Zanen, Marleen; Jansonius, Pieterjans.
We found clear correlations between management measures, tree characteristics and fruit characteristics. This means that growers can regulate apple quality during the growing season. On the basis of the two apple experiments, we can distinguish respective sets of growth and differentiation parameters and evaluate them in the light of conventional fruit cultivation science. Our results have little new value for fruit growing in practice, however. The value of our research lies in the approach developed to draw up a quality concept and the way in which we can apply this concept to crops about which little knowledge exists regarding the relationship between management measures, crop characteristics and product quality characteristics. Our research also offers...

Effect of organic and conventional farming systems on nitrogen use efficiency of potato, maize and vegetables in the Central highlands of Kenya
Provedor de dados: 21
Autores: Musyoka, Martha W.; Adamty, Noah; Muriuki, Anne W.; Cadisch, Georg.
Increased per capita food production in the tropics is closely tied to soil organic matter and water management, timely nitrogen (N) supply and crop N use efficiency (NUE) which are influenced by farmingsystems. However, there is lack of data on the effect of organic farming systems on NUE and how thiscompares to conventional farming systems under tropical conditions. Therefore, the objectives of thisstudy were to determine the effect of conventional and organic farming systems at low and high management intensities on N uptake and N use efficiency of potato (Solanum tuberosum L.), maize (Zea mays L.),cabbage (Brassica oleracea var. Capitata), kale (Brassica oleracea var. Acephala) and Swiss chard (Beta vul-garis sub sp. Cicla). The organic high input...

Improving Crop Yield and Nutrient Use Efficiency via Biofertilization - A Global Meta-analysis
Provedor de dados: 21
Autores: Schütz, Lukas; Gattinger, Andreas; Meier, Matthias; Müller, Adrian; Boller, Thomas; Mäder, Paul; Mathimaran, Natarajan.
The application of microbial inoculants (biofertilizers) is a promising technology for future sustainable farming systems in view of rapidly decreasing phosphorus stocks and the need to more efficiently use available nitrogen (N). Various microbial taxa are currently used as biofertilizers, based on their capacity to access nutrients from fertilizers and soil stocks, to fix atmospheric nitrogen, to improve water uptake or to act as biocontrol agents. Despite the existence of a considerable knowledge on effects of specific taxa of biofertilizers, a comprehensive quantitative assessment of the performance of biofertilizers with different traits such as phosphorus solubilization and N fixation applied to various crops at a global scale is missing.

Provedor de dados: 21
Autores: Koller, Martin; Vieweger, Anja; Mäder, Paul; Total, René; Bauermeister, Regula; Baur, Robert; Suter, Daniel; Mayer, Jochen.
Green manuring is an important tool in organic vegetable growing by fixing nitrogen, recycling nutrients in the rotation, and maintaining soil fertility through adding organic matter. The aim of this project was to optimise the incorporation of different green manure mixtures and to optimise green manuring during winter after vegetable crops with a late harvest in autumn.

Er der krummer i din jord – eller er det bare knolde
Provedor de dados: 21
Autores: Elmholt, S.; Schjønning, P.; Munkholm, L.J.
Jordens krummer er vigtige for vækst. Både vækst af afgrøden og de svampe og bakterier, der laver bindemidler til nye krummer. Vi har undersøgt, hvordan praktisk økologisk og konventionel drift påvirker dette samspil. Et varieret sædskifte med meget græs og husdyrgødning gav gode stabile krummer med højt indhold af biologiske bindemidler. Et ensidigt kornsædskifte med kunstgødning gav i stedet stabile knolde, hvor bindemidlet var ler. Sådan nogle knolde kan give et dårligt såbed, fordi våd jord bliver blød som mudder og tør jord hård som beton.

Einfluss verschiedener Zwischenfrüchte als Vorfrüchte für die Ertrags- und Qualitätsleistung von Silomais und Kartoffeln
Provedor de dados: 21
Autores: Schliesser, Ingeborg; Schuster, Martina; Kolbe, Hartmut.
Mehrjährige Gefäß- und Feldversuche des Landesamtes für Umwelt, Landwirtschaft und Geologie in Sachsen zeigen, dass Zwischenfrüchte zu höheren Erträgen bei Silomais oder Kartoffeln führen können. Zudem konnte bei bestimmten Zwischenfrüchten eine deutliche Verringerung des Nitratgehalts im Boden nachgewiesen werden.  Insbesondere der Anbau von Weißem Senf, Sommerraps, Phacelia und Welschem Weidelgras verringerte den Nitratgehalt um bis zu 75 Prozent des Bodenausgangsgehaltes. Ähnliche Wirkung zeigten das Landsberger Gemenge und ein Gemenge aus Phacelia, Buchweizen und Platterbse. Damit können Zwischenfrüchte gut zur Verringerung des Nitrateintrags ins Grundwasser beitragen.    Bei reinen Leguminosen ist die Nitrataufnahme aus dem Boden aufgrund ihrer...

Phosphat-Mobilisierung durch Haupt- und Zwischenfrüchte nach Düngung von weicherdigem Rohphosphat im ökologischen Landbau
Provedor de dados: 21
Autores: Steffens, Diedrich; Stamm, Roland; Leithold, Günter; Schubert, Sven.
Obwohl die agronomische Wirksamkeit von weicherdigem Rohphosphat gering ist, wird weicherdiges Rohphosphat im organischen Landbau gedüngt. Das Ziel des Projektes war es in Feld- und Gefäßversuchen in einer Fruchtfolge 2002/2003 und 2003/2004 zu prüfen, ob weicherdiges Rohphosphat von phosphataneignungseffizienten Pflanzen (Weißlupine und Ackerbohne) für phosphataneignungsineffiziente Pflanzen (Spinat und Mais) mobilisiert wird. Es zeigte sich, dass die P-Aufnahme von Spinat in einer Fruchtfolge mit Weißlupine und Ackerbohne höher war als in einer Fruchtfolge mit Sommerweizen. In Gefäßversuchen führte die Applikation von neuem Thomasphosphat (CaHPO4) zu einer höher Phosphataufnahme der Pflanzen als Rohphosphat.

Nitrogen fertilizer value of cattle manure applied on soils originating from organic and conventional farming systems
Provedor de dados: 21
Autores: Langmeier, Monika; Frossard, Emmanuel; Kreuzer, Michael; Mäder, Paul; Dubois, David; Oberson, Astrid.
Nitrogen nutrition of plants in organic farming depends largely on animal manure. In a pot experiment the hypothesis was tested that on a long-term organically managed soil (ORG) characterized by higher soil microbial activity, a greater portion of N applied as cattle manure is mineralized and taken up by plants than on a conventionally managed soil that had received exclusively mineral fertilizers (MIN). Dry matter yields and N uptake by Italian ryegrass were higher by around 20% on ORG than MIN soil. The N utilization of 15N labeled animal manure components and mineralNdiffered little between ORG and MIN. The major part of the increasedNuptake on ORG compared with MIN was due to a significantly greater N supply from ORG soil. The increased capacity of...

Post-harvest effect of cover crops on creeping thistle Circium arvense
Provedor de dados: 21
Autores: Thi Thuy, Hong Phan; Thorup-Kristensen, Kristian.
Cover crops move nitrogen (N) to the top soil. This enhances the N uptake of the succeeding barley crop, especially at early growth stages, and limits the access of the thistle to the N from the subsoil. The autumn tillage for perennial weed control, in contrast, provides a N distribution favorable for the uptake by thistles rather than barley crop. The evidence of post-harvest effect of cover crops on the N status of C. arvense gives a better understanding of their roles in weed control.

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...

Autores: Gruber, Harriet; Titze, Andreas; Wegner, Carolina.
Auf dem ökologischen Versuchsfeld der Landesforschungsanstalt für Landwirtschaft und Fischerei Mecklenburg-Vorpommern in Gülzow wurde in zwei Feldversuchen der Effekt von Schwefeldünger auf Körnerleguminosen (Lupinen und Erbsen) und Kleegras getestet. Wenige Wochen nach der Düngung stieg der Schwefelgehalt im Boden an, was sich jedoch nicht in einer Ertragserhöhung auswirkte. Im Kleegras konnte mithilfe der Schwefeldüngung sowohl der Leguminosenanteil signifikant gesteigert werden als auch der Schwefel- und Proteingehalt in den Pflanzen. Aus diesem Grund ist eine Überprüfung des Schwefelgehaltes im Boden für ökologisch wirtschaftende Betriebe zu empfehlen, besonders auf sandigen Standorten. Zur Schwefeldüngung im Frühjahr eignet sich aufgrund der...

Stickstoff ist im Biologischen Landbau in der Regel knapp. Die Fixierung von Luftstickstoff durch die Symbiose von Knöllchenbakterien und Leguminosen stellt die wichtigste Stickstoffquelle dar. Standortangepaßte Arten und Sorten sowie Leguminosen Nichtleguminosen-Gemenge können sie fördern. N-Fixierleistung und Flächenbilanzsalden sind bei Futterleguminosen höher als bei Körnerleguminosen. Die Salden sind bei Nutzung als Gründüngung positiver als bei futterbaulicher Nutzung und hier wiederum positiver als bei Verkauf des Erntegutes. Der Leguminosenanteil in der Fruchtfolge sollte 25 - 30% nicht unterschreiten.

Fosfor og kalium holdes levende i grøngødninger og efterafgrøder
Provedor de dados: 21
Autores: Korsgaard, Maren.
Efterafgrøder bruges især til at bevare kvælstoffet i de øvre jordlag og hindre det i at vaske ud. Men efterafgrøder opsuger alle næringsstoffer og forebygger dermed også udvaskning af eksempelvis svovl og kalium. Fosfor udvaskes ikke så let, men kan blive bundet så hårdt i jorden, at det ikke er tilgængeligt for planterne. En grøn jord med plantevækst vil forebygge at dette sker, idet fosforet indbygges i planterne og dermed bevares på tilgængelig form til den efterfølgende afgrøde.

Durch den Ausbruch von EHEC-Keimen in Norddeutschland ist das Potential von krankheitsauslösenden Keimen aus Gemüsepflanzen ins Bewusstsein geraten. In dem transnationalen, mehrjährigen Projekt „PathOrganic“ wurden mögliche Übertragungswege dieser und anderer pathogener Bakterien von Mist und Gülle zum verkaufsfähigen Gemüse untersucht. In Gülle- und Mistproben sowie auf erntereifem Gemüse wurden Keime gefunden. Grundsätzlich besteht ein erhöhtes Gesundheitsrisiko, wenn zu kurz nach dem Ausbringen von Mist oder Gülle Gemüse gepflanzt wird und in der Kette bis zum Konsumenten gute Wachstumsbedingungen für die Keime auftreten, wie etwa bei geschnittenem, in Schutzatmosphäre abgepacktem Gemüse.

Effects of Cattle Slurry on the Growth Potential and Clover Proportion of Organically Managed Grass–Clover Leys
Provedor de dados: 21
Autores: Steinshamn, Håvard.
The growth potential of grass-clover leys as influenced by cattle slurry application and clover content was studied in field experiments during three growing seasons at four locations. A grassland growth model was used to quantify growth potential and to separate the influence of weather variables from factors related to the plant stand. Application of cattle slurry increased the initial relative growth rate (R-s), on average from 0.21 to 0.23 g g(-1) day(-1) of the spring growth. In regrowth the effect of cattle slurry was less pronounced. The effect of cattle slurry declined with increasing R-s of the unfertilized treatment and rose with increasing rate of ammonium N applied by the slurry. The positive response to cattle slurry application on R-s was...

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...

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...

Influence of storage of deep litter manure on ammonia loss and uniformity of mass and nutrient distribution following land spreading
Provedor de dados: 21
Autores: Hansen, Martin N.
Deep litter manure contains considerable amounts of plant nutrients and is therefore used as a fertiliser in crop production. However, the manurial value of deep litter manure is reduced by ammonia volatilisation and uneven land spreading. Although storage before spreading may improve the spreading evenness of deep litter manure, it may also influence the potential for ammonia losses. A study was therefore designed to investigate how storage of deep litter ma-nure influences spreading evenness and ammonia volatilisation following land spreading. The ammonia volatilisation following land spreading was found to be reduced by 44% following storage, as the ammonium content of the deep litter manure had declined considerably during the storage period. The...

Yield responses and nutrient utilization with the use of chopped grass and clover material as surface mulches in an organic vegetable growing system
Provedor de dados: 21
Autores: Riley, Hugh; Løes, Anne-Kristin; Hansen, Sissel; Dragland, Steinar.
Trials were performed with red beet and white cabbage in 1998-2001 to assess the effects on yields and nutrient utilization of surface mulch (chopped grass and/or red clover). No other nutrients were applied. Nitrogen (N), phosphorus (P) and potassium (K) contents were measured in mulch, saleable products and above-ground plant residues. A single mulch application of about 12 Mg DM ha-1 increased the yields of both crops significantly. Mean yields of saleable products were increased from 27 to 33, and from 44 to 56 Mg FW ha-1 of red beet and white cabbage, respectively. However, the average apparent recoveries of mulch derived nutrients in above-ground plant parts (calculated by subtraction of uptakes in the control treatment) were only 13%, 14% and 18% of...

Mineralization of lupine seed meal and seedlings used as          N fertilizer in organic vegetable production
Provedor de dados: 21
Autores: Katroschan, K.; Stützel, H.
Seeds of grain legumes are currently discussed as N fertilizer in organic vegetable production. They can be produced by the farmers themselves and applied in well controlled amounts flexibly in time and space. Most research investigating the N mineralization of grain legume seeds was carried out using coarsely milled seeds. We hypothesized that seed germination alters the chemical composition leading to a higher N release compared to seed meal. In a pot experiment the C:N ratio of lupine seeds was shown to decrease noticeably within the first two weeks after sowing. After an incubation period of 1300°Cd net N mineralization was significantly higher for the lupine seedlings compared to the seed meal and close relationships between N mineralization and C:N...

Localized application of sewage sludge improved plant nitrogen and phosphorus uptake by rhizobox-grown spring wheat
Provedor de dados: 21
Autores: Wang, Yaosheng; Stoumann Jensen, Lars; Magid, Jakob.
Sewage sludge (SS) can be used as an alternative fertilizer in agriculture. It is normally broad- casted and plowed into soil, but it is not clear if it has a potential as a placement fertilizer. A rhizo- box experiment was conducted to investigate the placement effect of SS and mineral nitrogen (N) fertilizer on shoot and root growth as well as nutrient uptake of spring wheat (Triticum aesti- vum L.). The treatments included localized SS, mixed SS, localized SS and ammonium, local- ized ammonium, and a control without addition of SS and ammonium to examine the effect of SS placement and, further, if ammonium co-localization would enhance the placement effect. The re- sults show that SS fertilization improved soil N and P availability, which significantly...

Autores: Petersen, J.
The changes in weed:crop competition as affected by the interaction of slurry distribution pattern with crop sowing pattern was examined, using the parameters  dry matter (DM) production, nitrogen (N) uptake and recovery of applied N in spring wheat and weeds. Pig slurry enriched with isotopic nitrogen (15N) was applied either fully incorporated or in concentrated bands. The two slurry distribution patterns were combined with either crop density or distance between the slurry band and seed row. Spring wheat and weeds were sampled separately seven times during the season. A high and fast crop recovery of applied N coincident with a low recovery in weeds may be obtained by at least three management elements: sowing the crop with a high seed density, sowing...

SUSTAINABLE PRODUCTION PACKAGES FOR ORGANIC TURMERIC
Provedor de dados: 21
Autores: Somasundaram, Eagan; Shanthi, G.
Turmeric (Curcuma longa L.), a perennial rhizomatous herb has been regarded as an important spice in Asian cuisine. India is called as the “Spice bowl of the world” as it produces variety of spices with quality. Though India leads in production of turmeric, but average productivity is very low due to imbalanced and suboptimal dose of chemical fertilizers, organic manure, bio – fertilizers and micronutrients (Kandiannan and Chandragiri, 2008). Since, turmeric is a nutrient responsive crop and removes large amount of nutrients from soil, sufficient quantities of nutrients have to be applied in order to obtain sustainable yield levels (Nagarajan and Pillai, 1979). Application of organic source of nutrients (Wellgro formulations) would augment nutrient uptake,...

Inorganic nitrogen in soil green manured with biocidal crops
Provedor de dados: 21
Autores: Marchetti, Rosa; Casadei, Nerio; Marino, Antonio; Sghedoni, Lidia.
The knowledge of the dynamics of inorganic N in soil may help to establish the most suitable timing for green manure (GM) incorporation, which leads to the improvement of crop N use efficiency in conventional as well as organic agriculture. The practice of green manuring with crop species belonging to the Brassicaceae family has recently expanded, in Italy and abroad, due to their demonstrated biocidal effect against soil-borne pathogens. In this plot-scale study we monitored the release of soil inorganic N in 3 soil types (1 clay and 2 loams), in the months following late-spring green manuring with plant material from Brassica juncea, Sinapis alba, and Raphanus sativus species. Soil inorganic N content increased and reached a maximum 2 months after GM...

Compost, as a product of recycling processes, can be a very appropriate input material for organic farming, provided the composting process is well-managed, the input materials are free of contaminants, and the resulting product is applied according to the system’s ecological needs. Compost is a very important input material for organic greenhouse production. Organic greenhouse production may vary in the level of intensity, but it is generally a system with high turnover rates of organic matter, high inputs of both nutrients and energy, and high production levels. Compost is used as an important source of organic matter and nutrients in greenhouse horticulture, and is an important component of growing media for nurseries. Compost plays an important role in...

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...

Organic amendments and organic vegetable farming under plastic cover: Observations after six years of application
Provedor de dados: 21
Autores: BRESSOUD, F.; ARRUFAT, A.
During an experiment carried out over a six-year period, annual applications of large quantities of two types of compost led to an increase in the carbon level in the ground but had little impact on its physicochemical characteristics. No significant effect was revealed on successive vegetable crops. In contrast, it was shown that these cropping systems had specific characteristics. Cropping conditions under plastic cover lead to a high level of mineralisation of the endogenous organic matter and a limited lixiviation of nutrients. As a result of frequent over-fertilisation practices in the past in conventional farming systems, deep soil horizons may contain large stocks of minerals, part of which will be tapped by crops over the years following a...

Autores: Gruber, Harriet; Thamm, Uwe.
The following paper shows the impact of organic farming on the development of contents of phosphorus, potassium, magnesium and pH in the soil. The basis is a six-year crop rotation with animal manures (ca. 85 dt/ha/a) in the location of Gül-zow (Mecklenburg-Prepomerania). From 1993 to 2003 samples of soil were taken with aa soil auger in a depth between 0 and 30 cm. The discussion of changes in the nutrient contents are connected with nutrient balances. As a re-sult, organic farming does notnot lead to lower nutrient contents in soil. Only the content of potassium shows a decreasing tendency. The pH is atat a high level and the content of magnesium increases a little.   --  (Sprache des Volltextes: Deutsch)

Nitrat-Stickstoff-Gehalte im Boden in einer 6-feldrigen  Fruchtfolge
Provedor de dados: 21
Autores: Gruber, H.; Thamm, U.; Michel, V.
In ökologisch bewirtschafteten Systemen ist Stickstoff häufig der begrenzende Wachstumsfaktor. Daher stehen Bemühungen um seine effektive Nutzung innerhalb der Fruchtfolge im Mittelpunkt vieler Untersuchungen. Diese Problematik ist besonders auf humusschwachen Sandstandorten Nordostdeutschlands von Bedeutung. Je sandiger der Boden desto geringer ist sein Wasser- und Nährstoffspeichervermögen. In der Folge steigt die Gefahr der Nährstoffauswaschung, was insbesondere den Stickstoff betrifft. Einerseits geht dem Betriebskreislauf dadurch Stickstoff verloren, andererseits erfolgt ein verstärkter Eintrag in den Wasserkreislauf.  Von 1993 bis 2002 wurden in einer 6-feldrigen Fruchtfolge am Standort Gülzow in Mecklenburg-Vorpommern auf dem ökologisch...

Gründüngungen richtig gewählt, mehr Stickstoff für die Hauptkultur
Provedor de dados: 21
Autores: Koller, Martin; Vieweger, Anja; Bauermeister, Regula; Total, René; Suter, Daniel; Mäder, Paul.
Gründüngungen sind wichtig zur Versorgung des Bodens mit Humus und Stickstoff. Sie vermindern das Auswaschen der Nährstoffe sowie die Oberflächenerosion und können das Unkrautwachstum unterdrücken. Die Biorichtlinien fordern neu, als Ersatz zum Bodenschutzindex, einen Mindestanteil Gründüngungen, der entweder ganzjährig oder über den Winter angebaut werden kann. Die Frage der Begrünungsmöglichkeiten nach Gemüseernten im Oktober ist für den Gemüseanbau besonders wichtig.

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.

Autores: Sangakkara, Dr Ravi; Weerasekera, Mr Danesh; Attanayake, Mr K B; Attanayake, Ms A M U.
The impact of organic matter and two types of inoculums on composting and subsequent growth of common beans was evaluated under tropical field conditions. The composts were made of commonly available organic matter with different C:N ratios, and inoculums consisting of  cattle manure slurry, Effective Micro organisms or a mixture of both were added. The  mixture of cattle manure and Effective Microorganisms increased N availability and reduced C: N ratios of compost than when applied individually. Legume green matter enhanced compost quality and growth yields. The nodulation and mycorrhizal populations of roots of beans were increased by a mixture of inoculums and using diverse materials in the compost. The usefulness of inoculums such as EM, which is...

Autores: Jung, Rüdiger; Rauber, Rolf.
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.

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).

Verger de kiwi (Actinidia) conduit en Agriculture Biologique : résoudre le problème de la fertilisation
Provedor de dados: 21
Autores: Romet, Lionel.
Compte-tenu des besoins de la plante, la fertilisation est le problème majeur de la production de kiwi en Agriculture Biologique. Pour avoir de l’azote assimilable par le kiwi après son débourrement il est possible de fertiliser avec du guano d’oiseaux. La date de l'apport apparaît comme primordiale.  Le tourteau de ricin qu 'il soit sous forme de bouchon ou en semoule ne convient pas pour des épandages hivernaux, car sa minéralisation est beaucoup plus lente et est partielle sur une année.

The challenge of imbalanced nutrient flows in organic farming systems: A study of Organic greenhouses in Southern Germany
Provedor de dados: 21
Autores: Zikeli, Sabine; Deil, Lucia; Möller, Kurt.
Organic greenhouse vegetable production is characterized by very high nutrient demands within short growing periods and high nutrient exports via products sold. Therefore, meeting crop nutrient demands and maintaining long-term sustainability in these systems is highly challenging. To gain insight in current practices this study assessed fertilization strategies and nutrient flows of ten organic horticultural farms (22 greenhouses and polytunnels) in Southwest Germany belonging to the two organic farming associations Bioland and Demeter (biodynamic) for a cropping period of three years. Soil samples were taken to analyze plant available phosphorus, potassium, soil organic carbon, pH and salinity. Crop rotations in the greenhouses were very diverse, though...

Anaerobic digestion of manure - consequences for plant production
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Johansen, A.; Pommeresche, R.; Riley, H.
Organic farming systems are today dependent upon fossil energy. Another challenge are soil nutrient concentrations, which may be depleted with time even in animal husbandry systems (Løes &amp; Øgaard 2001). Anaerobic digestion (AD) of animal manure may produce biogas to replace fossil fuels, and reduce methane (CH4) emissions during manure storage. Co-digestion of substrates rich in energy increases the economic viability of the biogas plant, and off-farm substrates such as fish silage or household waste may add nutrients to the farming system. AD may also ease manure handling, while reducing the amount of weed seeds and animal pathogens. A reduced proportion of easily degraded C in the AD-manure may however impact the soil fauna/microflora and humus...

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...

A microarray spotted with 369 different 16S rRNA gene probes specific to microorganisms involved in the degradation process of organic waste during composting was developed. The microarray was tested with pure cultures, and of the 30,258 individual probe-target hybridization reactions performed, there were only 188 false positive (0.62%) and 22 false negative signals (0.07%). Labeled target DNA was prepared by polymerase chain reaction amplification of 16S rRNA genes using a Cy5-labeled universal bacterial forward primer and a universal reverse primer. The COMPOCHIP microarray was applied to three different compost types (green compost, manure mix compost, and anaerobic digestate compost) of different maturity (2, 8, and 16 weeks), and differences in the...

NJF-seminar Soil Stresses, Quality and Care    Different people understand differently the word soil. The soil can be looked upon as a body of nature and a part of the landscape. To many people soil is the substrate for plant growth and a prerequisite for food production and wealth. A third and perhaps growingly important view is soil as the physical ground for housings, roads and industry.    Soil is important to the whole society, not only for the agricultural sector. Soil has important ecological functions as it interacts with the dead bedrock, the atmosphere, the water, and the living organisms. Important functions are:    Biomass producer and transformer  Geomembrane, filter and buffer  Habitat for living organisms  Raw material and building ground...

One consequence of the BSE-crisis is, that animal residue derived N-fertilisers used in organic horticulture are to be replaced. As an alternative plant derived N-fertilisers have been investigated. In an incubation experiment these fertilisers mineralised 40 to 60  % of the total N applied. Net N-mineralisation in the incubation experiment as well as plant N-utilisation in a pot experiment were closely related to the N-content of the fertilisers. Fertilisers increased the N-uptake of plants in any soil. Neither texture nor the content of Corg explained the observed differences in fertiliser use efficiency .

Evaluation of the Photoacoustic Multi-gas Monitor during measurements of gas emissions from composting livestock manure
Provedor de dados: 21
Autores: Hansen, Martin N.; Maahn, Merete.
Livestock manure contributes significantly to the atmospheric concentration of ammonia (NH3) and green house gasses. Increase in the atmospheric concentration of these gasses cause serious environmental impact locally and globally. There is therefore a need for abatement technique to reduce the gas emission from manure, and for safe and reliable measuring methods. The Photoacoustic Multi-gas Monitor (PMM) is an efficient and handy method for continuous and simultaneous measurements of concentrations of different gases and its reliability was therefore tested during measurements of gas emission from a store of composting livestock manure. Concentrations of ammonia, methane (CH4) and nitrous oxide (N2O) in airflows entering and leaving a store of composting...

Optimierung des Futterleguminosenanbaus im viehlosen Acker- und Gemüsebau
Provedor de dados: 21
Autores: Stumm, Christoph; Köpke, Ulrich.
Die Nutzung von Sprossmasse als Dünger bietet auch für viehlose Betriebe die Möglichkeit, den Anbau ihrer Futterleguminosen auf dem Geberfeld hinsichtlich Stickstofffixierleistung und Lachgasverlusten zu optimieren und gleichzeitig die Erträge, besonders auf nährstoffärmeren Nehmerflächen zu steigern. Wird der Aufwuchs oberflächig als Mulch ausgebracht, kann die Verunkrautung signifikant reduziert werden.  Die Schnittnutzung von Futterleguminosen als Dünger kann mittels Lohnunternehmer (Schnitt, Feldhäcksler und Kompoststreuer/Siloballenpresse) ohne Investitionsaufwand jederzeit dem eigenen Bedarf angepasst werden; die Mehrkosten im Vergleich zum Mulchen belaufen sich auf etwa 150 €/ha je Schnitt.

Autores: Hospers-Brands, A.J.T.M.; Burgt, Geert-Jan H.M.; Strien, J. van.
Dit rapport bevat de resultaten van het tweede 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. Soms betreft het een vergelijking met de toediening van dierlijke mest, soms gaat het om verschillende hoeveelheden van toegediende maaimeststoffen. Er zijn geen verrassende resultaten, met uitzondering van een perceel tarwe waarbij een gift maaimeststof zonder (wel geplande) dierlijke mest geen meeropbrengst gaf ten opzichte van helemaal geen bemesting. In de stroken met meerdere jaren maaimeststof toediening zijn nog geen metingen verricht aan bodemkwaliteit en bodemleven. Dat komt later in het...

Binnen het project "Bodemkwaliteit op Zand" heeft het Louis Bolk Instituut verkenningen uitgevoerd naar de effecten van een jaarlijkse compostgift op de bodemkwaliteit: organische stof gehalte, beschikbaarheid van stikstof voor de gewassen en verliezen van stikstof. Daarvoor is gebruik gemaakt van het stikstofmodel NDICEA. NDICEA berekent op basis van gegevens over bodem, gewassen, bemesting en weergegevens hoe de organische stof dynamiek verloopt en hoe ten gevolge daarvan stikstof in de bodem vrijgemaakt, vastgelegd en door gewassen opgenomen wordt. In het project, uitgevoerd op de PPO-locatie Vredepeel worden drie teeltsystemen met elkaar vergeleken: een biologisch systeem en twee geïntegreerde systemen, waarvan een met een normale aanvoer van...

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: Georgieva, S.; Christensen, S.; Petersen, H.; Gjelstrup, P.; Thorup-Kristensen, K.
The assemblages of microbial (bacteria and fungi), microfaunal (protozoa and nematodes) and mesofaunal (microarthropods) populations were studied in decomposing root residues from hairy vetch (Vicia villosa Roth) and rye (Secale cereale L.) in a litterbag field experiment. Litterbags containing vetch or rye root residues were buried in soil at the same day as either vetch or rye winter catch crops were incorporated into the field soil from which the materials were gathered. The litterbags were sampled after 6 weeks in the field. In vetch, bacterial and fungal biomasses were similar whereas fungi dominated microbial biomass in rye. The biomass of the bacterial consuming fauna dominated by nematodes and microarthropods was similar to the biomass of bacteria...

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. Dies macht deutlich, dass bei der Beurteilung unterschiedlicher Mistformen neben N-Verlusten und N-Gehalten insbesondere die N-Wirkung...

From slash and burn to 'slash and mulch'
Provedor de dados: 21
Autores: Félix, Georges.
In semi-arid cropping regions of West Africa, fallow periods are getting shorter. As land becomes more scarce, farmers are not able to give their soils enough time to rest. This is leading to depletion of soil organic matter, severely threatening soil fertility and damaging soil structure. In the worst cases, crops hardly yield anything anymore, even with the addition of chemical fertilizers. In Burkina Faso, some farming families have found ways to restore their soil productive capacity through the use of low external input practices, based on mulch application of branches and leaves from local flora. The techniques described in this article are relevant for organic farming systems as they rely mainly on locally-available resources and diminish the...

Zowel grasklaver en luzerne is uitstekend veevoer, dat staat buiten kijf. Toch kiezen akkerbouwers en tuinders er soms voor grasklaver en luzerne niet af te voeren, maar op het eigen bedrijf te gebruiken als maaimeststof. Anders dan bij een groenbemester wordt het gewas niet ingewerkt op het perceel waar het is gegroeid. In plaats daarvan wordt het gewas gemaaid, gehakseld, en als plantaardige meststof (maaimeststof) op een ander perceel gebruikt. Wat zijn maaimeststoffen en waarom worden ze gebruikt? Hoe kunnen maaimeststoffen worden ingezet, en waar moet u op letten bij het gebruik? Dat staat in deze folder. Bovendien worden praktijkervaringen met maaimeststoffen beschreven.

Ertrag und Qualitätseigenschaften von Sommerweizen und Kartoffeln bei organischer Düngung tierischer Herkunft (Rottemist) und pflanzlicher Herkunft (Ackerbohnenschrot)
Provedor de dados: 21
Autores: Raupp, Joachim.
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...

Schnittgutabfuhr oder Gründüngung? Auswirkung der Kleegras-Nutzung auf Nitrat im Sickerwasser und Folgefrüchte
Provedor de dados: 21
Autores: Dreymann, Sonja; Loges, Ralf; Taube, Friedhelm.
A field experiment was conducted to evaluate the impact of different management systems of grass-clover (various cutting and/or mulching combinations) and date of ploughing (autumn or spring) on the fate of nitrogen (N) and the yield of succeeding wheat. The 3-cut system resulted in nitrate losses below the limit of the EC Nitrate Directive (91/676/EEC), even with ploughing in autumn. When ploughed in spring, treatments with frequent cutting and/or mulching induced nitrate leaching below the critical value. In contrast, losses from swards mulched only once were considerably above the threshold value, independently of ploughing time. With swards mulched and ploughed in autumn, nitrate concentrations exceed the EC-limit. The management of grass-clover swards...

Developing a Strategy for Sustainable Improved Soil Productivity in the Tropics - Efficient Management of Crop Residue/Farm Waste
Provedor de dados: 21
Autores: Odion, Ehiabhi Cyril; Ibrahim, Usman; Sambo, Banake Elisha; Ahmed, Adamu; Mukthar, Aisha.
Harvest index, which measures the economic harvest of a crop, often refers to that part of a crop representing that which can be eaten or sold to others for consumption; in smallholder farming. The remainder of the crop, referred to as crop residue; is either fed to livestock, used to build fences, used as mulch, ploughed in (where such equipments are available) or burnt in small-scale farming, causing environmental pollution. These crop residues are also rich in nutrients that were extracted from the soil, used in the building of the edible parts and contribute to soil mining if not returned to the soil. This is a major bottleneck among smallholders as harvesting could take place when the soil is too dry to turn easily or they may not have the labour to...

Designing cover crop mixtures to enhance potential weed suppression in organic no-till vegetable systems
Provedor de dados: 21
Autores: Ranaldo, Marzia; Carlesi, Stefano; Costanzo, Ambrogio; Bàrberi, Paolo.
Cover crops play a key role in weed management strategy in no-till organic and low input vegetable systems. The ability of cover crops to reduce weed pressure can be  linked to the amount of biomass produced at the time of cover crop devitalisation. Cover crop mixtures, in particular functional diversity in cover crop mixtures, can be managed to improve biomass production and weed suppressive ability of cover crops. We tested eight cover crop species pure stands and designed nine cover crop mixtures at increasing levels of functional diversity. The aim of this study was to highlight the effect of cover crops' functional diversity in controlling weeds before aubergine (Solanum melongena L.) transplanting. We showed that the functional composition (i.e. the...

Improving supply and phosphorous use efficiency in organic farming systems
Provedor de dados: 21
Autores: Walker, R L; Watson, C A; Rees, R M; Stockdale, E A.
Phosphorus (P) is an essential plant nutrient that needs to be managed carefully in organic systems so that crop yield and quality remain sustainable without contributing to environmental damage, particularly that associated with eutrophication. Under organic regulations, minimally processed rock phosphate (PR) can be used to amend low P fertility soils, although the solubility is extremely low at optimum soil pH for most crop growth (pH 6.5). This paper describes a project (PLINK) which aims to develop methods of improving P efficiency on organic farms, although the same approaches may also be applicable on conventional and low-input farms. The methodologies that the project is developing include the fermentation and composting of crop waste material with...

Agriculture belongs to the major sources of the trace gases nitrous oxide (N2O) and methane (CH4). However, little is known about the contribution of the increasing area of organically managed arable soils in organic farming systems to the greenhouse gas emissions.  The objective of our study was the quantification of the in-situ N2O- and CH4- emissions in common organic crop cultivation without livestock. In comparison to this control variant, we focused on the manuring effect of fermented herbal organic matter on the emissions (biogas variant). The straw of the crops and the growth of the intercrops were harvested, fermented in a biogas reactor and applied as fertilizer on the field when the nutrient demand of the crops occurred.  The results obtained in...

Radmyllning och kombisådd av flytande gödselmedel i ekologisk spannmålsodling
Provedor de dados: 21
Många ekologiska gårdar har begränsad djurhållning och är därför hänvisade till gröngödslingsgrödor och inköpt växtnäring för att åstadkomma fungerande odlingssystem. Den inköpta växtnäringen ger ekoodlarna möjlighet till flexibilitet och marknadsanpassning. Vidare ökar förutsättningarna för snabb omläggning från konventionell till ekologisk odling.                En möjlighet att minska kostnaderna för inköpt växtnäring är att minska förädlingsgraden, exempelvis beträffande gödselmedlens torkning och granulering. Exempel på sådana produkter är olika typer av flytande gödselmedel, bl.a. vinass. Gödselmedlets låga förädlingsgrad ställer jämförelsevis höga krav på spridningstekniken.

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.

In a field experiment at the Experimental Farm for Organic Farming in Northern Germany, the effect of sulphur application in the form of MgSO4 to a red clover-grass mixture was measured in the year 2011. At the beginning of the vegetation period in the spring plots were fertilised with 30 and 60 kg S ha-1. The sulphur fertilisation resulted in significantly higher fresh weight and dry matter yields and otherwise in a lower dry matter content as compared to an unfertilised treatment. The content of crude protein and sulphur were significantly increased by sulphur application. The N/S-ratios in the fertilised plots showed values below the threshold of 15 for an adequate supply of sulphur. The N-withdrawals added up over the three cuts increased in the...

Soil quality improvements provide an environment for plant nutrient uptake that impacts the development and yield of the crop. Thus, this study evaluated the effect of applied poultry composted organic manure (PCOM) on selected soil physical attributes and soil organic carbon content (SOC) under two tomatoes (UC82B and BESKE) varieties planted in succession. Three rates 0, 10 and 20 t ha-1 of compost were applied to two tomato varieties. The treatments were arranged in a randomized complete block design (split-plot layout). The soil physical parameters considered are - bulk density, aggregate stability, total porosity and SOC. It was observed that application of PCOM increased SOC, total porosity, aggregate stability and decreased the bulk density in the...

Site adjusted organic matter balance method for use in arable farming systems
Provedor de dados: 21
Autores: Kolbe, Dr. Hartmut.
Common humus balance methods give distinct inexact results and do not meet nowadays requirements in Germany. Outgoing from the method of KOERSCHENS et al. (2004) an improved, site adjusted, semi-quantitative method was developed for manual use in agricultural practice and consultation. In the validation and optimization process over 300 variants from 39 long-term field trials were used, which represent the most important site conditions of Central Europe (Germany). The optimization work was done in four steps.    Identification of site specific groups with homogenous humification levels. Distinct different humification characteristics were recognized for the organic matter of different German site conditions (soil, climate). Six site specific groups could...

Autores: GALAL ELGHARABLY, Ahmed.
The aim of this research is to improve the quality of organic farm compost, in order to satisfy soil fertility status required for reasonable organic vegetable production. Field experimental trial has been conducted on ALHODA organic farm, Ismaillia Governorate, Egypt. This experiment was carried out during the summer of 2002 to study the effect of some plant and animal residues (crop residues, cow manure, chicken manure, bone meal and animal hoof) in addition to natural mineral sources (rock phosphate and orthoclase). All were piled, prepared in three different mixtures and composted for 6 months. Three treatments C1, C2 and C3 were composed of 40 % crop residues + 20 % chicken manure + 40 % cow manure (control), control + 500 kg rock phosphate + 300 kg...

Økologisk bioenergi og jordkvalitet
Provedor de dados: 21
Autores: Johansen, Anders.
Mange aktiviteter i landbruget anvender fossil energi. Dette også er tilfældet i økologisk jordbrug, selvom det er en del af det økologiske tankegods, at bedriften kan klare sit energibehov ved bæredygtig lokal energiproduktion. I det lys undersøger vi i   FØJO-projekt (BIOCONCENS), hvordan husdyrgødning, plantebiomasse samt eventuelle andre organiske materialer fra følgeindustrier kan bruges som input til produktion af biogas og bioethanol. I laboratorie- og markforsøg tilbageføres restmaterialer fra biogas- og bioethanolproduktion til jorden som plantegødning. Mikrobielle og fysiske parametre  detekteres og bruges som indikatorer for hvordan jordens kvalitet og fertilitet påvirkes af de forskellige bioenergi-restmaterialer.

Risk of heavy metal accumulation in agricultural soil when livestock manure and organic waste is used for fertilisation
Provedor de dados: 21
Autores: Hansen, Martin N.
Increased use of livestock manure and organic waste within agriculture may cause soil accumulation of heavy metal. Sewage sludge and composted organic waste are important heavy metal sources. However, livestock manure is the major source of copper and zinc. Heavy metal balances calculations have shown that actual annual inputs of especially copper and zinc exceeds annual output considerably, which may create unacceptable soil concentrations of heavy metals in regions with dense livestock production.

Zügiger Umsatz bei vielen der im Brutversuch getesteten  organischen Handelsdünger
Provedor de dados: 21
Autores: Laber, Hermann.
Am Sächsischen Landesamt für Umwelt, Landwirtschaft und Geologie (LfULG) in Dresden-Pillnitz wurde im Winter 2012/2013 ein Brutversuch mit verschiedenen organischen Handelsdüngern pflanzlicher und tierischer Herkunft durchgeführt. Die Bebrütung mit Oberbodenmaterial eines stark lehmigen Sandes wurde bei 15°C über 11 Wochen durchgeführt.  Die Netto-N-Mineralisation der Düngemittel lief zumeist ‘zügig‘ an, so dass nach 14 Tagen bereits rund 25 bis 45 % der gedüngten N-Menge mineralisiert waren. Lediglich ein Dünger auf Schafwollbasis sowie sehr grobe Hornspäne zeigten zunächst einen langsameren Mineralisationsverlauf.  Der zeitliche Verlauf der Mineralisation konnte, mit Ausnahme des Schafwolldüngers und der Hornspäne, sehr gut mit einer ‘monomolekularen‘...

Nutrient supply to organic agriculture as governed by EU  regulations and standards in six European countries
Provedor de dados: 21
Autores: Løes, Anne-Kristin; Bünemann, Else K.; Cooper, Julia; Hörtenhuber, Stefan Josef; Magid, Jakob; Oberson, Astrid; Möller, Kurt.
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...

Auswirkungen der Beregnung von Kartoffeln in Abhängigkeit der Stallmistdüngung auf den Ertrag, die Qualität sowie die Verarbeitungseignung zu Pommes frites und Chips
Provedor de dados: 21
Autores: Krause, Tanja; Böhm, Herwart; Loges, Ralf; Taube, Friedrich; Haase, Norbert U.
Ökologisch erzeugte Kartoffeln, die zur Verarbeitung zu Pommes frites oder Chips genutzt werden sollen, müssen besondere Qualitätseigenschaften aufweisen. So wird beispielsweise ein mittlerer bis hoher Stärkegehalt bei gleichzeitig niedrigen Gehalten an reduzierenden Zuckern gefordert. Um den von der verarbeitenden Industrie geforderten Qualitätsansprüchen gerecht zu werden, ist neben einer ausgewogenen Düngung gerade auf leichten Böden auch eine ausreichende Wasserversorgung entscheidend, die oft nur über Beregnung sichergestellt werden kann. Unter den Fragestellungen, ob organischer Dünger (Stallmist) durch die Beregnung besser von den Verarbeitungskartoffeln ausgenutzt werden kann und inwiefern Ertragsstruktur und die Qualitätsparameter von...

Anaerobic digestion for closing the loop of a biorefinery for organic farming: Production of biogas and organic fertilizer from process residues
Provedor de dados: 21
Autores: Fernandez, Maria Santamaria; Ytting, Nanna Karkov; Lübeck, Mette; Uellendahl, Hinrich.
The availability of organic animal feed for monogastric animals and organic fertilizer is in many regions a limiting factor for the further spread of animal breeding and crop cultivation in organic farming. The production of these two commodities is the main target of a green biorefinery concept based on regionally organically grown grass biomass, called Organofinery. Anaerobic digestion of the residual streams after protein separation for the organic feed product is a key process to extract both the energetic and the nutritional value of the residual biomass in the biorefinery. Biogas potentials of the residual streams from the processing of red clover and clover grass (press cake obtained from screw pressing to produce green juice and brown juice after...

Potential uses for bracken (Pteridium aquilinum (L.) Kuhn) in organic agrculture
Provedor de dados: 21
Autores: Donnelly, E; Robertson, J; Robinson, D.
Bracken is a weed species due to its toxic nature and adverse effects on agriculture and ecology. This poster reviews research into historical uses for fronds and litter harvested as part of organically approved control methods. The use of bracken as an over winter mulch reduced losses of nitrogen and potassium from bare soil and maintained soil temperatures. Bracken litter was found to be a viable biofuel, with a calorific value comparable to wood and low ash and alkali metal contents. The contents of frond ash were investigated, with high concentrations of potassium found giving them a value as organic fertiliser. The addition of frond ash to soil significantly increased clover growth and number of nodules. The addition of frond ash to soil significantly...

Biogas in organic agriculture: Effects on yields, nutrient uptake and environmental parameters of the cropping system
Provedor de dados: 21
Autores: Möller, Kurt; Stinner, Walter; Leithold, Günter.
System effects of biogas fermentation in organic cropping systems with and without livestock (dairy farming) were investigated from 2002-2005. In both systems no differences in yields and nutrient uptake were detected in the legume crops. In the livestock-system non legume crops of the slurry system had no higher yields but a higher nitrogen uptake (6 %) than the stable manure system. Slurry-fermentation had no effect on yields and nitrogen uptake. The inclusion of crop residues in the fermentation system increased the nitrogen uptake about by 10 % and reduced the nitrate leaching potential by ca. 10 %. The inclusion of external substrates lead to a further increase in nitrogen yield of 10 %, but to no significant increase in dry matter yields....

Technique of green mulch spreading
Provedor de dados: 21
Autores: Schäfer, Winfried; Väisänen, Jaana; Pihala, Marjo.
Finland’s policy of subsidising the conversion to organic production precipitated the rapid growth of organic farming in the 1990’s. As a consequence, many stockless farms encountered the problems of nitrogen deficit, poor grain quality, and weed control. Since the spreading of green mulch on cash crops is very common especially in tropical agriculture, organic fertilisers like green mulch may be an alternative that would compensate for the prohibition on the use of mineral N-fertilisers. However, one problem is that presently there is no appropriate technique available to substitute for the strenuous handwork of spreading green mulch.     The main subject of this research report is the technique of green mulch spreading. Between 1994 and 1997, a green...

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...

Phosphorus bioavailability of sewage sludge-based recycled fertilizers
Provedor de dados: 21
Autores: Wollmann, Iris; Gauro, Ajay; Müller, Torsten; Möller, Kurt.
Six phosphorus (P) fertilizers recycled from sewage sludge [Struvite SSL, Struvite AirPrex,P-RoC, Mephrec, Pyrolysis coal and Ash (Mg-SSA)] were tested for their plant availability in potted soil of pH 7.2 under greenhouse conditions. The crop sequence simulated a rotation of red clover (Trifolium pratense L.), maize (Zea maize L.), and ryegrass (Lolium perenne L.). Other P fertilizer treatments included: Phosphate Rock (PR), Calcium dihydrogen phosphate [Ca(H2PO4)2], and an unfertilized control. Additionally, soil was regularly inoculated with two strains of plant growth-promoting rhizobacteria (PGPR; Pseudomonas sp. Proradix, and Bacillus amyloliquefaciens) to test their ability to increase P availability to plants. Sequential P  fractionation was...

Ammonia volatilization, nitrogen in soil, and growth of barley after application of peat manure and pig slurry
Provedor de dados: 21
Autores: Mattila, Pasi K.
Peat is added to manure, because its low pH and capacity to adsorb ammonia (NH3) give it potential to reduce nitrogen (N) loss. Peat manure was prepared by mixing pig slurry with moderately humified Sphagnum peat. Less than 1% of applied ammoniacal N was volatilized as NH3 from peat manure and pig slurry within 8 h of surface application on clay loam soil according to JTI method. Incorporated manures showed even smaller N loss. The low volatilization was due to the adsorption of manure ammoniacal N by peat, and the infiltration of slurry into harrowed, moist clay soil. In another experiment, peat manure was applied on polypropylene fabric without soil contact. Within the first 3 days there was only 9% reduction in the ammoniacal N of peat manure, but the...

Evaluation of the NDICEA model
Provedor de dados: 21
Autores: Burgt, Geert-Jan H.M.; Rietberg, P.I.
Within the N-Toolbox project the NDICEA nitrogen model, one of the key tools in the virtual Toolbox, has been improved and tested in England, Denmark and Spain. The model performance was evaluated on datasets from these three countries by means of visual observation, RMSE and RSR from the soil nitrogen dynamics. In England the scenarios with organic fertilizer performed better than those with artificial fertilizer, leading to the suggestion that the calculated nitrogen release out of fertilizer could be improved. Timing of the soil sampling on soil inorganic nitrogen is important to realize a good model evaluation; two samples only, before sowing and after harvest, is not enough. When soil mineral nitrogen samples were taken during crop growth, model...

Autores: Formowitz, B.; Elango, F.; Okumoto, S.; Buerkert, A.; Müller, T.
In Costa Rica, ‘effective microorganisms’ (EM) are used to produce organic fertiliser in the form of Bokashi. This study aimed at investigating the effects of EM addition on the decomposition of banana residues during Bokashi production in comparison to different non-EM control variants (Bokashi produced with: W= water, M= molasses as an EM additive, EMst= sterilized EM). Furthermore, the effects of the above mentioned Bokashi variants on the growth of young banana plants and their effects on the secondary root growth of adult banana plants were evaluated. In comparison to non-EM controls, no increasing effects of EM on the N-mineralization of banana material were observed. All nutrient concentrations were similar for all treatments as well as the weight...

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....

Manure samples from 194 farms with organic livestock production were analysed for their macro- and micronutrient contents. Guidance values for N, P, K, Mg and S concen¬trations given for conventional systems are within the range of values ¬determined here for organic farms. However, they can only be used for first estimations in fertilization planning, since – as demonstrated by the presented data – nutrient contents may vary over a wide range. This was also the case for the micronutrient concentrations (B, Cu, Zn, Mn, Mo and Se). Fertilization with 1t/ha dry matter of ma¬nure with higher micronutrient concentrations can cover the demand of organically produced crops in nutrient balances. Micronutrients applied with fertilizers or in feed additives are...

Establishing references to optimise organic fertilisation in organic rice farming in  the Camargue region of France
Provedor de dados: 21
Autores: MOURET, J-C.; HAMMOND, R.; BAYOT, M.; FABRE, D.; THOMAS, C.
The mineralization rate of a commercial organic fertiliser was evaluated over the course of three years in an organic rice field in the Camargue (France). The effect of different  mounts of fertiliser applied at different periods was tested. The organic fertiliser rapidly mineralised under flooded conditions. On the basis of this result, we demonstrated that an adaptation of organic fertilisation practices, similar to those employed for mineral fertilisers, would result in the optimisation of organic fertilisers, leading to improved profitability.

Yield and quality of potato tubers: Effects of different intensity and kind of manuring (biodynamic or organic)
Provedor de dados: 21
Autores: Neuhoff, Daniel; Schulz, Dirk Gerhard; Köpke, Ulrich.
Biodynamic farming is the oldest organic farming movement in Germany. Since Dr. Rudolf Steiner’s “Course on Agriculture” held in 1924, the number of biodynamic farmers in Germany has grown continuously, with 1,317 farmers currently producing on 47,592 ha. One of the most distinctive aspects of biodynamic farming is the use of the so-called biodynamic preparations, which are applied in homeopathic doses. Biodynamic preparations are supposed to improve plant growth and food quality, minimising natural variations. This paper deals with investigations of influences of these preparations and increased manure application on potato yield and tuber quality. The results are drawn from extensive research on organic potato production carried out by several institutes...

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.

Soil aggregation – a matter of proper management
Provedor de dados: 21
Autores: Elmholt, S.; Schjønning, P.; Munkholm, L.J.
Soil crumbs are important to soil functions. These include plant growth, and the growth of fungi and bacteria forming agents for binding and bonding of new crumbs. We have studied how commercial organic and conventional farming affect this interaction. A diverse crop rotation, including grass, and animal manure resulted in stable crumbs with a high content of biological binding and bonding agents. A cash crop rotation with the addition of only synthetic fertilizers resulted in small, stable aggregates – more like clods - with clay as binding agent. Such a soil will provide poor conditions for preparing seedbeds, because prolonged rain makes it soft and muddy while drought makes it hard as brick.

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...

In Sri Lanka the agricultural structure of smallholder production has changed with population growth and land reforms. In former days a farm family could life from the production of their home garden through subsistence farming and barter economy. Additional income was achieved by selling surplus products like spices on the local markets. Today living standards and life style have changed and monetary needs for housing, schooling, electricity, telephone, household goods and transport facilities are much higher. Many smallholders are involved in single cash crop cultivation and outside employment for income generation. Lack of available arable land and infrastructure are main reasons for the limited economical success of many smallholders in Sri Lanka. This...

Autores: Thomopoulos, MSc P.; Bilalis, Ass. Prof. D.; Konstantas, MSc A.; Efthimiadou, MSc A.
Two experiments were conducted in Greece, during the years 2005 and 2006, in order to evaluate the effect of two legumes (vetch: Vicia sativa and faba bean: Vicia faba) on the root development and yield of the following cotton. Concerning the cotton cultivation the Organic Agriculture guidelines were followed. In both years the higher values of the root characteristics of the cotton were found in the plots where vetch had been incorporated. The seed cotton yield for vetch was 2850 and 3137 kg ha-1 in 2005 and 2006, respectively. Furthermore, in both years, a statistically important factor of correlation, between the nitrogen quantities of the soil and the seed cotton yield, had been appeared.

Water soluble phosphate fertilizers for crops grown in calcareous soils - an outdated paradigm for recycled phosphorus fertilizers
Provedor de dados: 21
Autores: Meyer, G.; Frossard, E.; Mäder, P.; Nanzer, S.; Randall, D.G.; Udert, K.M.; Oberson, A.
Background and aims  The current paradigm for phosphorus (P) fertilizers applied to calcareous soil is that almost entirely water soluble P fertilizers are efficient and sparingly soluble P fertilizers are not efficient P sources for crops. We hypothesize that this paradigm does not apply to recycled P fertilizers and that other P pools can explain the plant use of recycled P fertilizers on calcareous soil.  Methods  We applied 33P isotopic dilution method to evaluate recycled P fertilizers based on plant P uptake from fertilizer relative to plant uptake from a water soluble P reference fertilizer. The predictability of fertilizer effectiveness based on sequentially extracted P forms and X-ray diffraction pattern of recycled fertilizers derived from sewage...

Maaimeststoffen,  het ei van Columbus?
Provedor de dados: 21
Autores: Van der Burgt, Geert-JanH.M.
De biologische landbouw is voor de aanvoer van stikstof uiteindelijk afhankelijk van de stikstofbinding door vlinderbloemigen als grasklaver of luzerne. Minder fosfaataanvoer, betrouwbare stikstof levering, hogere stikstofbenutting, met gelijke of lagere kosten en minder transport. Dat zijn argumenten om grasklaver of luzerne in een akkerbouw-bouwplan niet als veevoer te verkopen, maar zelf direct als meststof op het eigen bedrijf te gebruiken. Zijn maaimeststoffen echt zo aantrekkelijk?

IMPACT OF AGRICULTURAL MANAGEMENT ON COMMUNITIES OF ORIBATIDA, GAMASINA AND COLLEMBOLA IN ITALIAN AND FRENCH VINEYARDS
Provedor de dados: 21
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...

In het kader van het project Minder en Anders Bemesten is op het bedrijf van Jan en Hans van Lierop vervolgonderzoek uitgevoerd. In een veldexperiment in herhalingen is getracht de productie van courgette gelijkmatiger in het seizoen te verdelen door op twee peilers te steunen: een bescheiden bemesting om de productie in het begin van het seizoen te verhogen, en grasklaver als voorvrucht om de productie verderop in het seizoen te verhogen. De resultaten tonen dat deze aanpak werkt: met een relatief kleine bemesting is er geen sprake van een verlaagde opbrengst in de eerste helft van de productieperiode. Verder is de bodemstructuur verbeterd door de grasklaver en is de mestgift lager dan anders het geval zou zijn geweest.

Ecology of Earthworms under the ‘Haughley Experiment’ of Organic and Conventional Management Regimes
Provedor de dados: 21
Autores: Blakemore, Robert.
Significant differences in earthworm populations and soil properties were found in three sections of a farm at Haughley in Suffolk that, since 1939, had either an organic, a mixed conventional, or a stockless intensive arable regime.  Compared with the mean earthworm population of a 1,000 year old permanent pasture of 424.0 m-2; an organic field had 178.6 m-2; a mixed field 97.5 m-2; and a stockless field 100.0 m-2.  Species recorded were: Allolobophora chlorotica, accounting for most of the increase in the organic section; Aporrectodea caliginosa, dominant in the stockless section; Aporrectodea icterica; Ap. longa; Ap. nocturna; Ap. rosea; and Lumbricus terrestris.   Soil analyses showed the organic soil had higher moisture, organic C, and mineral N, P,...

kansen voor pluimveemest
Provedor de dados: 21
Autores: Staps, Sjef.
Pluimveemest is een hoogwaardige meststof met veel stikstof, fosfaat en kali. De hoge fosfaatwaarden maken de afzet echter moeilijk. Akkerbouwers kunnen een beperkte  hoeveelheid fosfaat per hectare uit dierlijke mest per jaar op hun land brengen.  Pluimveemest bevat vaak evenveel stikstof als fosfaat. Door de fosfaatbeperking kan met deze mest dan vaak niet genoeg stikstof op het land kan worden gebracht.  Het project ‘Kippenmest &amp; Kringloop’ was vooral bedoeld om te onderzoeken hoe de stikstof-fosfaat verhouding kan worden aangepast, zodat deze mest beter bruikbaar is  voor de teelt van gewassen. In dit BioKennisbericht vindt u informatie over de verschillende mogelijkheden.

Rhizome Fragmentation by Vertical Disks Reduces Elymus repens Growth and Benefits Italian Ryegrass-White Clover Crops
Provedor de dados: 21
Autores: Ringselle, Björn; Bertholtz, Erik; Magnuski, Ewa; Brandsæter, Lars Olaf; Mangerud, Kjell; Göran, Bergkvist.
Tillage controls perennial weeds, such as Elymus repens, partly because it fragments their underground storage organs. However, tillage is difficult to combine with a growing crop, which limits its application. The aim of this study was to evaluate how soil vertical cutting with minimum soil disturbance and mowing affect the growth and competitive ability of E. repens in a grass–clover crop. A tractor-drawn prototype with vertical disks was used to fragment E. repens rhizomes with minimal soil and crop disturbance. In experiments performed in 2014 and 2015 at a field site close to Uppsala, Sweden, the rhizomes were fragmented before crop sowing (ERF), during crop growth (LRF), or both (ERF+LRF). Fragmentation was combined with repeated mowing (yes/no) and...

LCA and Risk Assessment of Recycled Phosphorous Fertilisers
Provedor de dados: 21
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...

Effects of Biogas Digestion of Slurry, Cover Crops and Crop Residues on Nitrogen Cycles and Crop Rotation Productivity of a Mixed Organic Farming System
Provedor de dados: 21
Autores: Möller, Dr. Kurt; Stinner, Walter; Leithold, Prof. Dr. Günter.
Manures and crop residues can be utilised for digestion, without any significant losses of nutrients. This paper presents the results of field trials about the effects of biogas digestion in a mixed organic cropping systems on nutrient cycling and yield of a whole crop rotation. Digestion of slurry affected yields and N uptake only after soil incorporation. The inclusion of crop residues for digestion increased the amounts of “mobile” manure. N uptake and yield of non-leguminous main crops increased about 10%, due to a more adapted allocation of nutrients within the whole cropping system by reallocation of N towards the crops with higher N needs. Additionally, removing the cover crops in autumn and their digestion increased the fertilizing efficiency of N,...

Provedor de dados: 21
Autores: Möller, Kurt; Schultheiß, Ute.
One of the key issues in organic vegetable production in comparison to conventional production is the approach to soil and soil fertility, as is expressed in the regulations on permitted fertilizers and soil amendments. Vegetable crops are characterized by high nutrient contents and high production levels and consequently require high inputs of nutrients, mainly nitrogen and potassium. Furthermore, the cropping period of most vegetable crops is rather short in comparison to arable crops. The current fertilization strategy in practice is characterized by a base dressing of animal manure or compost, and top dressings that are applied throughout the growing season, using a variety of additional fertilizers like keratins (feather-, horn- and hair meal) or...

Cover crops and compost influence soil enzymes during 6 years of tillage-intensive, organic vegetable production
Provedor de dados: 21
Autores: Brennan, Eric B.; Acosta-Martinez, Veronica.
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,...

Effects of long-term farmyard manure applications on soil organic matter, nitrogen mineralization and crop yield – a modeling study –
Provedor de dados: 21
Autores: Dux, J.; Fink, M.
To develop sustainable cropping systems we need to predict both short-term and long-term effects of management practices on soil fertility. For this purpose agro-ecosystem simulation models are valuable tools. We used the Daisy model to simulate a three-year crop rotation (beetroot, onion, white clover, potato) over a period of 40 years. With this rotation, three rates of farmyard manure were tested (0, 15, 28 t ha-1 year-1). After 40 years without manure soil organic matter carbon (SOM-C) decreased by approximately 40%, and increased by 27% with the highest application rate. SOM turnover did not reach equilibrium at the end of the experiment. Nitrogen mineralization from SOM followed in the long-term (40 years) the slowly changing time courses of SOM....

Manure fertilization for soil organic matter maintenance and its effects upon crops and the environment, evaluated in a long-term trial
Provedor de dados: 21
Autores: Raupp, Dr Joachim.
The effects upon soil organic matter and crop yield of applying farmyard manure, both with and without biodynamic preparations, as compared to treatments receiving mineral fertilizer (and straw) have been studied in a field trial starting in 1980. The site has a sandy orthic luvisol, 590 mm precipitation per year and  9.5̊ C annual mean temperature. Since 1985/86, crop rotation is red clover, spring wheat, potatoes and winter rye. Soil organic matter (SOM) content in the topsoil has been found to be higher with manure than with mineral fertilization. The highest SOM content of 1.00 % Corg has been observed in the treatment with biodynamic preparations. Increasing applications gave higher SOM contents only with manure, but not with mineral fertilization....

The aim of the study was to establish a diagnostic tool to narrow down the causes for pea yield depressions. A differential two-level diagnostic test system was established under controlled conditions usingpeas (Pisum sativum L.) as test plants. Soils from 22 organically managed sites with unexplained moderate to high pea yield losses were tested in level 1 diagnostics (y-irradiation to eliminate potentiallyharmful organisms, nutrient additions to compensate for potential nutrient deficiencies or activated charcoal amendment to bind and thereby to immobilize potentially phytotoxic compounds). Results showedthat organisms harmful to the test plant were the primary cause of limited germination and growth inmost of the sampled soils, whereas a positive effect...

Fertilizer value and nitrogen transfer efficiencies with clover-grass ley biomass based fertilizers
Provedor de dados: 21
Autores: Benke, Anna Pia; Rieps, Ann; Wollmann, Iris; Petrova, Ioana; Zikeli, Sabine; Möller, Kurt.
In temperate regions, legume-based green manures are a key element of organic rotations.  However, specialized farms lack sufficient mobile organic fertilizers. To gain a better understanding of the N flows and the nitrogen (N) and phosphorus (P) fertilizer value of different clover-grass-based fertilizers (biogas digestate, compost, silage and fresh clover-grass obtained from clover grass ley biomass), we assessed their fertilizer value. Nitrogen and P offtake by the ryegrass was used to assess the shortterm effects. The data were completed using model calculations to assess the field-to-field N-transfer efficiencies and the overall N-transfer efficiencies.  The greatest plant N offtake was achieved with digestates (64%) and the lowest from the compost...

Aspects of phosphorous fertilisation in organic farming
Provedor de dados: 21
Autores: Schnug, E; Haneklaus, S; Kratz, S; Fan, X.
Balanced fertilisation is essential for a considerate use of limited phosphorus (P) resources and for sustainability in organic farming. Plant available soil P levels will decrease and soil fertility will diminish when using P sources with limited P availability such as rock phosphates, bone and bone meals. An in situ digestion with a combination product of elemental S and rock phosphate enhanced significantly the solubility of non water-soluble P sources. In addition to the problem of insufficient solubility, mineral P sources can be contaminated with toxic heavy metals such as Cd  0.1–92.3 mg kg-1) and U (&lt;LLD - 481 mg kg-1) from their source. Farmyard manure and slurry may contain up to 953/727 and 376/132 mg kg-1 Zn and Cu, respectively.

Einfluss von Zwischenfrüchten auf Lachgasverluste und  Nitratauswaschung im ökologischen Marktfruchtbau in Abhängigkeit von der Vorfrucht
Provedor de dados: 21
Autores: Böldt, M.; Loges, Ralf; Kluss, Cristof; Taube, Friedhelm.
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....

Influence of liquid manure application method on weed control in spring cereals
Provedor de dados: 21
Autores: Rasmussen, K.
Injection of liquid manure (slurry)into the soil is an alternative to the traditional surface application. By the injection method,it is possible to place nutrients closer to the crop sown, thus offering the crop a competitive advantage over weeds. This study compares the response in crop yield, weed density and weed biomass to injection vs. surface application of liquid manure through three growing seasons in barley and oats. The manure applications were combined with treatments of weed harrowing or herbicide  spraying or no treatment at all. The levels of weed control and crop yield obtained by harrowing and herbicides were larger when slurry was injected compared with surface application. Without any weed control treatments,the injection method...

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.

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...

The fertilizer value of human urine was compared with mineral fertilizer in pumpkin (Cucurbita maxima) cultivation at a dose of 113 kg N ha-1 with no-fertilization used as control. The growth of the vine was better in urine fertilized pumpkins than in mineral fertilized and non-fertilized pumpkins. Total fruit biomass was higher in mineral fertilized plants compared to urine fertilized and non-fertilized pumpkins. Urine fertilized pumpkins may have suffered from lower potassium or higher chloride, thus they produced fewer flowers and fruits. However, total fruit biomass and the number of fruits were slightly higher in urine fertilized plants than in their non-fertilized counterparts, i.e. 17.2 t ha-1 more pumpkin could be produced with urine fertilizer....

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...

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...

Organically produced legume seed meals are an upcoming alternative to established  fast mineralising organic fertilisers based on plant and animal waste products with  suspect origin (e.g. hornmeal). The turnover in soil was investigated with respect to  the influence of legume variety and seed meal texture. Variety specific differences in  net N mineralisation could be attributed to differences in C/N ratio and cellulose  content. The influence of texture classes on net N mineralisation was considerably  smaller than the influence of differences between the investigated species.

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.

Maaimeststoffen zijn gewassen die worden gemaaid en vervolgens als plantaardige meststof worden ingezet op een ander perceel dan waar ze geteeld zijn. In deze brochure beschrijven we hoe maaimeststoffen ingezet kunnen worden en wat dat betekent voor de mineralenstromen op het bedrijf en voor de bodem. Natuurlijk met volop praktische tips, zodat u direct zelf aan de slag kunt.

Organische Stickstoffdüngung bei mehrjährigen und mehrschnittigen Kulturen am Beispiel der Pfefferminze
Provedor de dados: 21
Autores: Blum, Hanna; Palitzsch, Katja.
Im ökologischen Anbau von Arznei- und Gewürzpflanzen zeigen sich bei mehrjährigen Kulturen starke Ertragseinbußen durch unzureichende Stickstoffdüngung. Das betrifft besonders Arten mit hohen Stickstoffentzügen, die drei bis viermal pro Jahr beerntet werden (beispielsweise Brennessel, Pfefferminze, Zitronenmelisse).  Am Beispiel der Pfefferminze wird der Einfluss verschiedener Stickstoffdünger auf das Ertrags- und Qualitätsverhalten getestet.

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...

Production de références pour optimiser la fertilisation organique en riziculture biologique camarguaise (France)
Provedor de dados: 21
Autores: Mouret, J.C.; Hammond, R.; BAYOT, M.; FABRE, D.; THOMAS, C.
La vitesse de minéralisation d’un engrais organique commercial a été évaluée durant trois années dans une rizière biologique en Camargue (France). L’effet de différentes doses d’engrais apportées à différentes périodes a été testé. En conditions inondées, l’engrais organique minéralise rapidement. Sur la base de ce résultat, nous montrons qu’une adaptation des pratiques de fertilisation organique, inspirée de celles appliquées pour des engrais minéraux, permet une meilleure valorisation des engrais organiques, découlant sur une meilleure rentabilité.

Fjäderfägödsel: innehåll av växtnäring och spårelement samt utveckling av provtagningsmetodik
Provedor de dados: 21
Resurshushållning av växtnäring innebär att stallgödsel ska utnyttjas så effektivt som möjligt i växtodlingen samtidigt som den negativa påverkan på omgivande miljö ska minimeras. Gödsel från fjäderfä produceras ofta på specialiserade enheter med liten egen odlingsareal. Fjäderfägödsel har därför blivit en handelsvara. För närvarande arbetar Jordbruksverket med att ta fram nya föreskrifter som gäller vid förmedling av gödsel. Ekonomiskt representerar växtnäringen i hönsgödsel ett stort värde. Ökad kunskap om fjäderfägödselns innehåll av växtnäringsämnen och spårelement gör det lättare att sätta rätt pris på produkten vid försäljning och att anpassa gödselgivan till grödans behov. Anpassning av givan till grödans behov och markförhållanden minimerar risken...

Düngungsstrategien im ökologischen Gemüsebau
Provedor de dados: 21
Autores: Perkons, Ute.
Futterleguminosen sind aufgrund ihrer Humusreproduktion und symbiotischen Stickstofffixierleistung die tragenden Elemente der Fruchtfolgegestaltung im Ökologischen Landbau. Der hohe Stickstoffbedarf gemüsebaulicher Kulturen wird derzeit meist über Zukaufdünger gedeckt, diese sind jedoch meist Reststoffe der konventionellen Tierhaltung. Vor diesem Hintergrund wird geprüft, inwieweit sich der Einsatz von Zukaufdüngern reduzieren lässt, indem betriebseigene Leguminosen-Schnitte und Komposte (Cut &amp; Carry) zur Düngung einer intensiven Gemüse-Fruchtfolge verwendet werden. Die Ergebnisse zeigen exemplarisch für Eissalat, dass bei der Nutzung von betriebseigenem Dünger in Form von Luzernefrischmasse mit Zukaufdünger vergleichbare Erträge erreicht werden....

Effects of traditional and biodynamic farmyard manure amendment on yields, soil chemical, biochemical and biological properties in a long-term field experiment
Provedor de dados: 21
Autores: Zaller, Johann G.; Köpke, Ulrich.
We studied the effects of applications of traditionally composted farmyard manure (FYM) and two types of biodynamically composted FYM over 9 years on soil chemical properties, microbial biomass and respiration, dehydrogenase and saccharase activities, decomposition  rates and root production under grass-clover, activity and biomass of earthworms under wheat, and yields in a grass-clover, potatoes, winter wheat, field beans, spring wheat, winter rye crop rotation. The experiment was conducted near Bonn, on a Fluvisol using a randomised complete block design (n=6). Our results showed that plots which received either prepared or non-prepared FYM (30 Mg ha−1 year−1) had significantly increased soil pH, P and K concentrations, microbial biomass, dehydrogenase...

Structural changes of plant residues during decomposition in a compost environment
Provedor de dados: 21
Autores: Dresbøll, Dorte Bodin; Magid, Jakob.
We investigated the actual degradation of plant material during composting by qualitative methods using Scanning Electron Microscopy (SEM) combined with quantitative chemical methods.  Decomposition of Mischanthus (Mischanthus oogiformis L.), hemp (Cannabis sativa L.) and wheat (Triticum aestivum L.) straw was observed by placing litterbags containing these materials in compost piles. Hemp and Mischanthus straw were more stable than the wheat straw, but the two materials differed in the way they were degraded despite similar chemical composition. Hemp straw was broken down in more flexible structures compared to the rigid breakdown of Mischanthus straw. We concluded that the anatomical arrangement of the tissue is just as an important part of the...

Source and temperature determine the releases of multiple amino acids from plant materials
Provedor de dados: 21
Autores: El-Naggar, Ahmed; Rasmussen , Jim; de Neergaard, Andreas; El-Araby, Ahmed; Høgh-Jensen, Henning.
Agricultural crop production is largely dependent on inputs of mineral fertilizers. Mineral fertilizer prices are expected to rise as the competition for fossil energy increases. In order to increase the sustainability of crop production, alternatives to commercial mineral fertilizers are needed. Organic residues and fresh biomass are potentially important sources of nitrogen (N) in crop production. A study was conducted to investigate the impact of temperature on the release rate and profile of amino acids from soybean seeds (Glycine max L.) and fresh young shoots of chicory (Cichorium intybus), alfalfa (Medicago sativa) and red clover (Trifolium pratense) under anaerobic conditions. Plant material was incubated in water at either 15 ◦C or 35 ◦C, and the...

Levenscyclusanalyse groencompost: grootschalig en zelf composteren.
Provedor de dados: 21
Autores: Dekker, P.H.M.; van Zeeland, M.; Paauw, J.G.M.
Door PPO-AGV is in 2009 een studie uitgevoerd om in een levenscyclusanalyse (LCA) de bereiding van groencompost op het agrarisch bedrijf te vergelijken met de bereiding van groencompost op regioschaal door gespecialiseerde composteerbedrijven.     Bereiding van groencompost op het agrarisch bedrijf heeft het voordeel dat flink bespaard kan worden op energieverbruik en vrachtvervoer op de weg. Daar staat tegenover dat gespecialiseerde groencomposteerders gebruik kunnen maken van schaalgroottevoordelen, betere sturing kunnen geven aan gewenste composteercondities en dat zij gebruik kunnen maken van groenafval van natuurgebieden. De studie bouwt voort op de studie die in 2008 is uitgevoerd, waarbij o.a. een LCA voor GFT-compost is opgesteld. Voor zover dat...

Vergelijking van verschillende types bemesting in een bio fruitaanplanting van Conference
Provedor de dados: 21
Autores: Vercammen, Jef; Gomand, Ann.
Tot op heden is er zowel in binnen- als buitenland heel weinig aandacht besteed aan het op punt stellen van de bemesting binnen de biologische perenteelt. Wanneer men enkel werkt met snelwerkende meststoffen als bloedmeel geeft men enkel N. Maar ook K is belangrijk. Daarom wordt er gekeken wat de mogelijkheden zijn van drijfmest, digestaat, stalmest, …  Naast de voeding geven deze elementen bovendien nog een zekere hoeveelheid organisch materiaal, wat zeker belangrijk is naar bodemstructuur en bodemleven. De vraag is echter of deze tragere meststoffen wel voldoende N leveren aan het begin van het seizoen. Om dit te ondervangen werd bij het laatste object gebruik gemaakt van humuszuren om de mineralisatie en de opname te vergroten.  Bij een oudere aanplant...
