Biological resources of mineral nutrition of agricultural crops in Krasnoyarsk territory

In agrarian and industrial complex of Krasnoyarsk Region because of the reduction of livestock of farm animals the pro- duction and use of manure has been several times reduced. In agrocenoses the decrease in potential and effective fertility of soils is observed. For the preservation of soils fertility and the increase of agricultural crops efficiency it is necessary to increase using all biological sources of plants mineral nutrition in agriculture as fertilizers. Rational use of manure, birds’ dung, crushed straw of grain and leguminous crops, siderates, vegetable remains and agronomical ores will raise the content of nutrients in soils and compensates their ex- tremely scarce balance in agriculture. The increase in the areas under leguminous crops, perennial legumes and using bacterial fertilizers will give the chance to increase the intake of biological nitrogen in agriculture of the region. Biologization of agriculture will allow bringing in addition into arable soils of Krasnoyarsk Region 14...
