Features of accumulation of vegetable field cultures remains in Central Siberia

Due to the reduction in production and use of manure in regional agriculture there is a need in rational use of fertilizer of vegetable remains of var- ious crops. The quantity of vegetable remains com- ing to the soil depends on the productivity of crops and use in animal husbandry. In different natural zones of the region the productivity of field cultures in 2015-2016 was unequal and depended on soils fertility, provision with nutrients, weather conditions, high-quality features, the technology of cultivation and the level of using mineral and organic fertiliz- ers. The highest rates of productivity of all cultivat- ed cultures were noted on Nazarovskaya and Chulym-Yenisei forest-steppe zones chernozyoms. In these zones the productivity of cultures was 1.5-2.0 times higher in comparison with subtaiga. In all natural zones of most of all collateral production, surface and root remains come to the soil at cultiva- tion of a winter rye and winter wheat (6.6- 10.5 t/hectare), fodder root crops (5...
