Datsko L. Changes in organic matter states of Polynesian Soddy-Podzolic Soils under various porns of agricultural use

Object of research - technology of cultivation of agricultural crops. An object of research - of a Soddy-Podzolic soil. Methods of research: field, laboratory, statistical. The purpose of research con-sists in studying influence of various systems of processing of ground on change of a condition humus, and also definition of agronomical, economic and power efficiency of cultivation winter neigh in a crop rotation. Theoretical and practical on the basis - of researches it is established tendencies of improvement of a condition humus soil un-der influence long (18 years) uses of different systems of processing and fertilizers. Recommendations for improvement of fertility of these soils are developed. Reliability and novelty of the received results is caused by significant volume of an experimental material which is received in complex researches together with Institute of an agricul-ture of Polesye with use of tool methods and statistical data process-ing. Novelty of researches consists in definition ofdynamics of proc-esses of formation humus under influence of different systems of processing and fertilizers. The degree of introduction and sphere of use - results can be used by development and improvements of soil-protective technologies which are based on a non-plow (V-blade) tillage to processing together with entering of organic and mineral fertilizers into quantities which provide sufficient balance humus. At cultivation of agricultural crops it is recommended to use a non-plow (V-blade) tillage processing on depth of 18-20 sm with entering 13,3 t/ha + N46Р51К62 pus on hectare of an area under crops.
