EFFICIENCY OF COMPLEX APPLICATION OF MINERAL FERTILIZERS AND CHEMICALIZATION MEANS AT SPRING WHEAT CULTIVATION ON LUVISOL SOILS

Abstract

At cultivation of spring wheat on luvisol soils productivity at level 68-71 c/ha is formed at entering N₆₀+N₃₀Р₆₀К₁₂₀ and N₆₀+N₃₀Р₅₀К₉₀ + Cu₅₀ +Mn₅₀ + seron or moddus + N₃₀ (stage 51-53). Thus the weight of 1000 grains on 4,5 g is more, the content of crude fiber on 1,0% above, and its gathering on 78 kg/ha is more at wheat cultivation on luvisol sand soil. However the maintenance irreplaceable and critical amino acids and biological value of fiber above in spring wheat at cultivation on luvisol loamy soil. Specific carrying out of nutritional elements by spring wheat at cultivation on luvisol soils increases at application of mineral fertilizers and chemicalization means, and also at increase of doses of mineral fertilizers. Specific carrying out potassium and calcium by spring wheat at cultivation on luvisol loamy soil almost twice above, than at cultivation on luvisol sandy soil.
