Influence of predecessors and technologies in control over batteries mode

Abstract

The results of studies on the effect of different precursors and technologies to the regime of organic matter and nutrients black earth southern carbonate and dark chestnut soils of Pavlodar region. In the southern black earth early rocker par with the traditional preparation technology provides an average level of NO₃ before sowing spring wheat (46.8 mg/kg), which number systematically decreases in subsequent crops, which indicates the need for nitrogen fertilizers. All studied species of vapor, used their training technology and intensification of different backgrounds do not have a significant impact on the availability of dark-brown loam soil nitrate nitrogen (N-NO₃) and mobile phosphorus. N-NO₃ content remains at a very low level-5 mg/kg in a layer 0-40 cm and at elevated P₂O₅ - 115-133 mg/kg in the 0-20 cm layer, indicating the need for a nitrogen fertilizer at higher doses.
