In the method to increase fertility of permafrost saline soils under conditions of the cryolyte zone a chemical improver is used - gypsum in the dose of 8 t/ha, and green manure - green mass of oats, 40 q/ha in the bushing phase, which is closed into soil. The green manure and the improver are added together into permafrost saline soils, which are poor in nitrogen, and the process of organic substance decomposition and accumulation is restricted by the soil permafrost condition. ^ EFFECT: improved chemical and physical composition of soil and increased productivity of fodder crops. |
