The aim of the present study was to investigate the impacts of different tillage intensity on the quantity of soil organic matter in topsoils of seven long-term trials. Tillage intensity was found to affect both bulk density and Ct-contents, whereas

Three different perennial legume species (Lotus corniculatus, Medicago sativa, Trifolium pratense) were cultivated in alternate drills with one of three different grasses each. L. corniculatus is known to be rich in tannins, which are supposed to hav

The impact of management and environmental site factors on quantitative and qualitative indicators of humus dynamics was investigated in eight long-term field experiments in Germany and neighbouring countries. Humus dynamics were basically influenced

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 yi

Under ecological crop growing conditions, considerable problems consistently arise in fulfilling the baking quality of winter wheat demanded by consumers. The “wide row” procedure shows promising potential for effectively using the nutrient suppl

A common practice in stockless organic farming systems is to leave the biomass from clover/grass-ley and crop residues in the field for their residual fertility effect. No farmyard manures for transfer of nutrients within the system are available. Cl

In two agricultural systems with and without animal husbandry the potential to produce renewable energy by digesting slurry and organic residues to biogas were assessed. In comparison to some other methods of energy production by biomass biogas produ

In organic farming systems without livestock some problems arise concerning the nitrogen management: On the one hand, there is a lack of transportable nitrogen fertilisers, on the other hand there is a potential for high losses with the usual managem
