Phosphorus compounds in primitive soils on mantle loam under various phytocenoses

摘要

The phosphate status of primitive soils having developed for 30 years on mantle loam under various phytocenoses have been studied by lysimetric experiment at the Faculty of Soil Science, Moscow State University. The qualitative composition of organic phosphates in soils at the initial stage of pedogenesis is shown to be almost the same for various phytocenoses but to be quite different from that in mature soils. Organic phosphates of primitive soils are nonresistant to alkaline hydrolysis, and a large amount of nucleic acids, phospholipins, and teichoic acids are found among them.
