During 10 years a crop rotation schedule consisting of different crops (green fallow; intercrop: winter wheat; peas; intercrop: winter rye; summer barley) was combined with three different tillage techniques (plough, inverting to 30 cm depth, intensive; two-layer plough, inverting to 15 cm depth and loosening to 30 cm depth, reduced inverting; layer cultivator, loosening to 30 cm depth, conservation tillage). First results show a significant effect of crop on springtails. There is no significant effect of tillage techniques, although there is a tendency in slightly increased population density of springtails by using plough and layer cultivator. Further detailed results will be reported elsewhere.

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

Zonas ripárias são áreas de saturação hídrica, permanente ou temporária, cuja principal função é a proteção dos recursos hídricos de uma microbacia. Essa pesquisa comparou a adequação do uso do solo de dois cenários de planejamento agrícola de uma microbacia: o cenário convencional, representando o método usualmente empregado, que apenas considera as classes de capacidade de uso da terra, e o cenário hidrológico, que inclui a delimitação e avaliação das zonas ripárias. Um estudo de caso foi realizado na Microbacia do Ribeirão São João (3.656 ha), no município de Mineiros do Tietê (São Paulo, Brasil). Mapas de Classe de Capacidade de Uso da Terra e de Adequação do Uso do Solo foram elaborados, utilizando o Sistema de Informação Geográfica (SIG), para a...

A long-term field experiment demonstrates the influence of tillage on the bacterial potential to produce soil structure-stabilizing agents such as exopolysaccharides and lipopolysaccharides

A method for soil health assessment in the conversion to organic farming

Cania, Barbara; Vestergaard, Gisle; Krauss, Maike; Fliessbach, Andreas; Schloter, Michael; Schulz, Stefanie.

Background: Stable soil aggregates are essential for optimal crop growth and preventing soil erosion. However, tillage is often used in agriculture to loosen the soil, which disrupts the integrity of these aggregates. Soil aggregation can be enhanced by bacteria through their ability to produce exopolysaccharides and lipopolysaccharides. These compounds stabilize soil aggregates by “gluing” soil particles together. However, it has yet to be shown how tillage influences the bacterial potential to produce aggregate-stabilizing agents. Therefore, we sampled conventional and reduced tillage treatments at 0–10 cm, 10–20 cm and 20–50 cm from a long-term field trial in Frick, Switzerland. We compared the stable aggregate fraction of the soil and the bacterial...

This paper was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR). The regulation for the assessment of the conversion to organic farming establishes the use of soil/produce pollution and the type of agricultural practices as indicators of performance. However, these indicators don’t reflect the complexity of the soil ecosystem and soil health. Therefore, complementary indicators were sought (soil biostructure and field capacity), and a specific three-steps method for the assessment and monitoring of soil health during the conversion process was developed.

LOCATELLI, M.; LEÔNIDAS, F. das C.; SAMPAIO, N. F..

Nos últimos vinte anos, Rondônia tem sido alvo de um intenso movimento de migração e implantação de projetos oficiais de colonização. O resultado desses processos foi a intensificação da atividade agropecuária no Estado, responsável pela abertura de aproximadamente, 6.000.000 de hectares de florestas. Após um período de abertura acelerada da fronteira, houve uma redução no ritmo de ocupação. Recentemente, a colonização em solos de menor fertilidade não permitiu sustentação econômica adequada a grande parte dos agricultores e o empobrecimento do campo passou a ser evidente. Além da baixa fertilidade dos solos, a grande incidência de doenças e os baixos preços dos produtos agrícolas, também influenciaram no insucesso econômico. Nos últimos anos, houve um...

ABSTRACT Intensive land use can affect macrofaunal biodiversity, which is a property that can be used as a soil quality indicator. This study evaluated the abundance and diversity of soil macrofauna and its relation to soil chemical and physical properties in five land use systems (LUS) in the eastern region of Santa Catarina. The following LUS were studied: native forest (NF), eucalyptus plantations (EP), perennial pasture (PP), integrated crop-livestock (ICL), and no-tillage cropping (NT). The macrofauna was quantified in 0.25 × 0.25 m monoliths and sampled in the 0.00-0.20 m layer in the summer (Jan/2012) and winter (Jul/2012). For each LUS, nine points were sampled, distributed in a 30 × 30 m sampling grid. After screening the edaphic macrofauna...

A macrofauna do solo exerce importante papel na ciclagem de nutrientes e agregação do solo, pois é responsável pela fragmentação dos resíduos orgânicos, mistura das partículas minerais e orgânicas, redistribuição da matéria orgânica e abertura de canais (bioporos). A abundância e diversidade da macrofauna do solo foram avaliadas em áreas submetidas a diferentes fases de um sistema de integração lavoura-pecuária, implantado em 2006, em Jardim Olinda/PR, sobre um Latossolo Vermelho arenoso (110 g kg-1 de argila). A área foi dividida em quatro módulos de 6 ha: P01 ? pasto/pasto/pasto/pasto/soja; P02 ? pousio/braquiária safrinha/ soja/milho + braquiária/soja; P03 ? pousio/milho + braquiária/soja/milho + braquiária/pasto; e P04 ? pousio/milho +...

Allons compter les vers de terre

Pommeresche, Reidun.

En god bestand meitemark spiser seg gjennom 25 % av matjordlaget hvert år. De har krås, og mikroorganismer i tarmen. Dermed går omdanningen av organisk materiale mye raskere med meitemark i jorda enn uten. Meitemarken bygger opp humus (mold), og ekskrementene er langt mer næringsrike og tilgjengelige for planterøtter enn jorda rundt.

Amino acid and soil organic matter content of topsoil in a long term trial with farmyard manure and mineral fertilizers

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...

Commencing in 1980, a long-term experiment is carried out to compare mineral fertilizers (MIN), composted manure (CM) and composted manure with application of biodynamic preparations (CMBD) at three different fertilizer application rates. With mineral fertilizer the lowest contents of 0.80% C and 0.069% N, with manure 0.90% C and 0.080% N, and with manure and biodynamic preparations 1.08% C and 0.094% N were achieved in the topsoil. 42.9 to 53.7% of Nt was bound in 18 protein amino acids including asparagine and glutamine. Amino acid contents in the hydrolysates of the topsoil were significantly different according to fertilizer type: MIN < CM < CMBD. The higher contents in manure fertilized plots were observed even at the lowest rate of fertilizer...

The below ground biodiversity of soil organisms plays an important role in the functioning of the the soil ecosystem, and consequently the above ground plant production. The objective of this study is to investigate the effect of grass or grass-clover in combination with fertilisation on the soil food web structure. In 2003 a fertilisation trial on grass and grassclover was sampled for soil organisms. Data were agglomerated in seven trophic groups, and classified by means of TWINSPAN. TWINSPAN clearly distinguished three main soil food web structures: Type 1: Grass plots with a high biomass of bacteria and fungi; Type 2: Grass-clover plots with a high biomass of earthworms; Type 3: Grass and grass-clover plots, that received relativily high...

Agriculture and biodiversity are closely connected. Especially the soil ecosystem is crucial in this relation. Earthworms are seen as good indicators for the health and functioning of the soil. Beneath different biodiversity measurese earthworm ecological group data is analysed to assess soil biodiversity, fertility and capability to deliver ecosystem services. However this kind of data is compositional and needs a special statistical treatment. New available methods for this purpose were applied to data from the BIOBIO project (www.biobio-indicator.org) to gain better understanding of the complex relationship between earthworms, agricultural management and environment.
