Change in agrochemical properties of texture-differentiated agrozem during application of green manure and organic and mineral fertilizers.

摘要

It is shown that the application of high doses of organic and mineral fertilizers (N₆₀P₆₀K₆₀+60 t/ha manure) and plowing under vetch and oats as green manure makes it possible in low-humified agrozems to reduce soil acidity by 0.5-0.6 pHKCl units, increase total exchangeable bases by 3.1-4.3 mmol/100 g soil, and increase organic matter content by 0.32-0.41%. This variant can be the basis of the technology of rehabilitating low-humified soils, since it provides a substantial increase of their fertility at a relatively low cost.Notes Translated from Doklady Rossiiskoi Akademii Sel'skokhozyaistvennykh Nauk (2011) No. 1, 28-30 Ru.
