Subject:
carbon; composts; farming systems; fertilizer application; linear models; mineralization; organic nitrogen; prediction; slurries; variance
Abstract:
... The prediction of nitrogen (N) mineralization or immobilization in organic fertilizers is an important tool to optimize fertilizer use, especially in intensive agricultural systems. Our aim was to derive a model to predict the N mineralization/immobilization from readily available information on the properties of organic fertilizers in farming practice. On the basis of a literature review, a chara ...
