Agrochemical condition and nutrition balance of newly irrigated light gray soils of Uzbekistan

This paper notes the geographical location, soil and climatic conditions, geomorphological geological structure of Jizzakh province, as well agrochemical status newly irrigated light gray soils formed in Arnasay district nutrients their balance autumn glaciers. According to results chemical analysis, it was found that mechanical composition studied consists sandy loamy soils, which fine sand particles (0.5-0.05%) predominate. The study showed driving layers humus present at 0.823-0.936%, total nitrogen 0.059-0.084%, phosphorus 0.096-0.135%, potassium 1.05-1.36%, mobile nutrients. It noted they belong very low low-income groups according level. amount mineral local fertilizers applied winter wheat, residues wheat crop stem (straw) grown relation amounts fall into by natural means is high (N-15.1 kg/ha, P-3, 6 K-34.4 kg/ha).
