Microorganisms are able to utilize nitrogen (N) from a wide range of organic and mineral
compounds. In this paper, we review the current knowledge about the regulation of the …

This review reveals that crop residues of common cultivated crops are an important resource
not only as a source of significant quantities of nutrients for crop production but also affecting …

The processes of N mineralization and immobilization which can occur in agricultural soils
during decomposition of plant residues are briefly reviewed in this paper. Results from …

The existence of soluble organic forms of N in rain and drainage waters has been known for
many years, but these have not been generally regarded as significant pools of N in …

The effect of soil inorganic N availability on the decomposition of maize residues was tested
under aerobic conditions in soil samples incubated for 125 days at 15° C. Carbon residue …

Publisher Summary Soils form a major repository of nitrogen (N) within both natural and
agricultural terrestrial ecosystems, containing, on a global basis, an estimated 2.4 x 10 11 …

The aim of this review is to describe and discuss the concepts that have been employed to
interpret N mineralization–immobilization in soil, and how N turnover is related to the …
