N‐P‐K balance in a milk production system on a C . nlemf uensis grassland and a biomass bank of P . purpureum CT‐115 clone

摘要：

In very intensive milk production systems in Europe and America with the use of high amounts of chemical fertilizers, the nutrient cycling models consider the losses of N due to leaching and volatilization, as well as the hydro‐physical characteristics of the soil affecting the performance of this element ( 10 ; 6 ).However, in more extensive milk production systems, low input agriculture forming the natural cycle occurring within each farm,is of vital importance to potentate nutrient recycling for a stable animal production.
