Influence of cultivation of secondary mung bean, soybean and oat crops on cotton yield and soil structure by different methods of tillage after winter wheat

Abstract This article provides information on the results of scientific research aimed at maintaining and increasing soil fertility in country world today, as well ways to increase it, impact organic fertilizers fertility. The presents evidence-based data study effect soybean, mung bean oat sowing different with deep, medium shallow tillage after harvesting winter wheat conditions prone wind erosion low fertility, mechanical composition light irrigated meadow saz, slightly saline soils for number bacteria accumulating nitrogen roots legumes root crop residues macroaggregates between options increased by 0.1-10%, porosity 0.6-1.5, humus content 0.001-0.004%, total 0.005%, nitrate 0.1-3.6 mg/kg. In variants row crops soybean a depth 30 cm wheat, yield grain was 16.5 c/ha, 18.8 where higher 2.1 soybeans 2.5 c/ha compared chisel treatment an average 22-24 cm. 14-16 using cultivator. With ordinary sowing, achieved profitability 48.1%, 52.7%. When growing cotton next year against background repeated plow from sown 33.4 centners / ha, 34.2 ha level 39.5%.
