Application of joint crops for balancing biologization agroecosystems Ukraine

Abstract

The ecological state of earth of the agricultural setting that is examined as a decision factor of receipt of high-quality agricultural raw material, forage and food products, is unsatisfactory from the intensive pattern of their economic use and anthropogenic-technogenic loading of making progress erosion, enhanceable acidity, salinization, overwetting, radiation contamination and development of other negative processes.
Stabilizing of development of agriculture is assisted by converting of modern agroecosystem into adaptive, it’s proof and permanent. Permanent ecosystems are possible only on condition of stabilizing of the contained humus in soil as a result of bringing of necessary amount of organic fertilizers, optimizations of betweenness cultivated and continuous sowing by cultures, minimizations of till, liming, gypsuming of soils and their protecting from erosion.
Dehumification, or reduction of humus, in soil is the controlled index of decline of his fertility. Long-term researches show that principal reasons of dehumification soils of Ukraine are a decline of general culture of agriculture, reduction of volumes of bringing of organic fertilizers, out-of-control development of water erosion and deflation.
Decalcification, or acid degradation of soils. It - one of peracute problems of contemporaneity and nearest future, that is related to the height of acidity of the ground cover and worsening of agrochemical properties of soils.
Contamination of soils is predefined by a presence for them of excessive amount of heavy metals, radionuclides, bits and pieces of pesticides and mineral fertilizers and others like that. On earth of the agricultural setting of contamination of soils, as a rule has local character and depends on placing of them near industrial objects, nuclear power plants, syllables of mineral fertilizers and pesticides. Physical degradation of soils is investigation of the intensive agricultural use of earth, namely: excessive thrown open of soils, intensive mechanical till and decline of content in soils of organic substance.
