Soil conditioner

Abstract

The invention discloses a soil conditioner. The conditioner comprises ammonium bicarbonate, oyster shell power, potash feldspar ore powder, 3,4-dimethylpyrazole phosphate, ammonium humate, chitin and other conditioning components. The acidity can be reduced, the pH value is improved, the utilization rate of nitrogen fertilizers can be fundamentally improved, the nitrate accumulation is reduced, the heavy metals can be immobilized, harmful pathogenic bacteria are inhibited, and calcium, silicon and other beneficial elements are provided for soil microbes and crops.

Description

technical field

[0001] The invention relates to a composition, in particular to a soil conditioner. Background technique

[0002] In China's agricultural production, the per-mu application of chemical fertilizers is increasing, especially nitrogen fertilizer. The per-mu nitrogen fertilizer is three times that of European and American countries, and the utilization rate is less than 50% of European and American countries. Excessive application of nitrogen fertilizer has caused excessive nitrate in the soil and soil acidification. , organic matter reduction, soil condition deterioration and other problems, so the fundamental of soil improvement and conditioning is to increase nitrogen fertilizer use efficiency and reduce nitrogen fertilizer application. Most of the other chemical fertilizers used are chemically acidic or physiologically acidic fertilizers, such as potassium chloride, potassium sulfate, ammonium sulfate, ammonium chloride, monoammonium phosphate, etc., and also...
