Description

CROP ROTATION, TILLAGE, FERTILIZER SYSTEM, MANURE, FERTILIZER, STRAW, GREEN MANURE, CROP, FERTILITY. Prolonged use of cultivation methods moldboard sod-podzolic sandy soil leads to differentiation of topsoil on indicators of fertility. There is a significant increase in their top 0-10 cm and 10-20 cm in reducing layer, whereas plowing their uniform distribution. For the systematic introduction of 10 tons of manure N45Р60К67,5 kg per 1 ha of crop rotation area reserves of humus in the arable soil layer (0-20 cm) 3 rotations 8 rotations of the fields increased compared with baseline at 2,4-7, 3 t / ha (12,1-29,3%) of mobile phosphorus in 3,0-3,4 times, exchangeable potassium in 1,3-2,2 times. Growing crops rotation 8 of the fields without the use of organic and mineral fertilizers degrades arable layer of sod-podzolic sandy loam soil and irreplaceable losses its fertility. Using the same system of fertilization by-products and stubble grain crops for green manure on a background of reduced doses of organic fertilizers doubled compared to conventional reserve-keeping can be reproduction and fertility sod-podzolic sandy loam soil. By making regular doses of conventional fertilizer depending on basic soil tillage methods yield clover hay increased in 1,9-2,3 times, spring wheat - in 1,6-1,7 times, winter rye - in 1,4-1 5 times and potato - in 2,4-2,8 times in comparison with unfertilized background. Against fertilizer system with elements of performance biologization crop rotation is reduced by 10-44% compared to conventional fertilization system. Proved that when growing wheat and rye winter after clover, maize and rapeseed preference should be given regular plowing under wheat ravine after potatoes, barley and triticale yare after diaper-oat mixture, diaper on the seeds after barley under maize silage after wheat Winter can be limited to shallow plowing, and under oats, potatoes, spring canola, annual grasses should be performed moldboard tillage disc and subsurface cultivator instruments.
