Title: FERTILIZER FOR IMPROVING ALKALI SOIL
Abstract:
A fertilizer for improving alkali soils is obtained by mixing the following raw materials, all in parts by weight: 40-60 parts of crop straw powder, 30-50 parts of crop carbonized powder, 15-26 parts of NPK compound fertilizer, 14-23 parts of urea, 15-28 parts of salt adsorbent, and 1-3 parts of complex microbial agents. In addition to the effects of both inorganic and organic fertilizers, the fertilizer is more effective in providing complete improvement of the source of soil organic microorganisms and the acidity and alkalinity of the soils. The fertilizer can also produce active substances, stimulate crop growth, fix atmospheric nitrogen, participate in transformation of nutrients, and promote absorption of nutrients by crops, increase soil buffering performance, improve acidic soil, and modify the alkali soils.
