Effects of Fertilizer Rates and Compost Application on the Amount of Organic Waste Left Winter Wheat and Reproductive Crops in the Soil

Abstract

In this article, data are given about the effect of application of semi-rotten black manure of cattle and compost on the background mineral fertilizers recommended for winter wheat N₂₀₀ P₁₄₀ K₁₀₀ kg / ha, as well as the effect of left stubbles of the crops and nutrients in the soil and nutrients in their content. In addition to the recommended rates of mineral fertilizers for winter wheat, the application of 10; 20 t / ha of semi-rotten black manure and compost on average from 3.72 tons to 4.05 tons per hectare of organic residue provided, and thus, it was left 11.5-12.9 kg / ha of nitrogen in the soil, 5.2-6.0 kg / ha of phosphorus, 6.7-7.7 kg / ha of potassium, on average from 2.29 to 2.46 tons per hectare by semi-rotten black manure of cattle and compost, it was found that 32.4-37.2 kg / ha of nitrogen, 17.5-20.5 kg / ha of phosphorus and 27.5-31.8 kg / ha of potassium are returned to the soil due to organic residues.
