Organic phosphorus of the soil and its mineralization.

The question of the composition of organic phosphorus in soil and pathways of its mineralization is discussed. The literature data and the author's own results on the content of polyphosphates in microorganisms and in soil are cited. Possible ways of studying the accessibility of soil factors depending on the composition of the microflora and degree of polymerization of immobilized inorganic polyphosphates are discussed.
