METHOD TO IMPROVE PERMAFROST SOILS FERTILITY UNDER PERMAFROST ZONE CONDITIONS

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to agriculture, in particular, to farming, fodder production and plant growing. Proposed method comprises using green fallow, application of mineral fertilizers and use of multifunctional tillage units. At that, moisture closing is performed using needle harrow BIG-3A at depth of 4-6 cm, soil tillage at depth of 5-7 cm, introducing mineral fertilizers in (NPK)₃₀ dosage, fodder crops sowing and tillage using compaction unit Ob'-4-ZT. Fodder crops green mass is ploughed using heavy harrow BDT-3.0, starting from tillering phase, at depth of 18-20 cm, and soil tillage is performed using tillage set APK-5.7 at depth of 16 cm.;EFFECT: method allows to improve and preserve soil fertility under permafrost zone conditions, as well as to improve soil structure.;1 cl
