Expert assessment of security of arable soils of Ukraine with macroelements of plant nutrition

Abstract

The purpose. To give expert assessment of natural fertility of arable soils of Ukraine concerning their security with macroelements of plant nutrition on the basis of modern methodical and theoretical development. Methods. Statistical-mathematical analysis of materials of automized data bank of agrochemical properties of soils. Theoretical basis of probes is the concept considering edaphic systems as open polymorphic and polycomponent thermodynamic systems. Results. Analysis of materials SE «Institute of protection of soils of Ukraine» has displayed availability of factors preventing deriving exact state assessment of fertility of soils concerning their security with macroelements of plant nutrition. It is connected to imperfection of methods of edaphic diagnostics and methodology of realization of agrochemical certification of lands. The soil factors preventing deriving objective state assessment of fertility are also specified. Conclusions. Now the average content of nitrogen, phosphorus and potassium in soils of Ukraine matches to means of their security with these nutrients. Therefore on all natural soils of the country it is impossible to receive stable heavy yields of crops without application of conforming doses of organic and mineral fertilizers.
