WebTaking mineralization from organic materials into account In the long run, organic products inputs add nitrogen to the stable organic materials present in the soil. Those quantities of mineralisable nitrogen must be taken into account through soil analysis, in order to estimate the amount of nitrogen available to the plants. WebIn agricultural practices in which the use of inorganic fertilizer is being reduced in favour of the use of organic manure, the availability of nitrogen (N) in soil for plant growth depends increasingly on N mineralization. In simulation models, N mineralization is frequently described in relation to the decomposition of organic matter, making ...
