The effective management of nitrogen dynamics is essential for cropping systems which have the double objective of achieving acceptable yields and minimizing environmental impact. The decisions to be made are both particularly complex and of great ur

The structure of the soil in the arable layer is controlled by tillage, soil biota activities and weathering, whereas the structure below this layer is mainly the result of the activities of soil biota. Organic farmers tend to minimise the depth of t

The effect of two decomposition processes, digestion and composting, was compared on the quality of the final residue from two substrates: hay and straw. The digestion was done by using dwarf goats on digestion crates and the composting process was s

Recent findings concerning nitrogen cycling and dynamics are discussed. Ruminants excrete most of the N intake in urine, from which it is easily lost. By proper management of liquid manure in the case of loose housing, losses can be reduced to about

Reconfiguration of farming systems to reach various productive and environmental objectives while meeting farm and policy constraints is complicated by the large array of farm components involved, and the multitude of interrelations among these compo

For three ecological mixed arable-dairy farms on sandy soils in the Netherlands the nutrient balances for N, P and K have been assessed on the basis of inputs and outputs of products, manure, fodder and straw. For nitrogen the assessment of N-fixatio
