InactiveCN107915548AImprove micro-ecological environmentGood physical propertiesCalcareous fertilisersAgriculture tools and machinesSodium BentonitePhosphate
The invention discloses an agricultural water-retaining soil-loosening soil conditioner and a preparation method thereof. The conditioner is prepared from the following components: 20 to 55 parts of calcium ammonium nitrate, 0.1 to 10 parts of monoammonium phosphate, 0.1 to 5 parts of ammonium sulfate, 10 to 35 parts of potassium humate, 0.1 to 1 part of polyacrylamide, 0.1 to 3 parts of biological enzyme, 0.5 to 2 parts of magnesium oxide, 2 to 6 parts of potassium fulvate, 5 to 10 parts of bentonite, 5 to 10 parts of light calcium carbonate. The agricultural water-retaining soil-loosening soil conditioner is stable in nature, and can be combined with various means such as improving microecological environment of the soil, loosening compacted soil, and improving physical properties of thesoil, thereby ultimately improving the utilization rate of a fertilizer and yield and quality of crops, and avoiding problems of imbalances in proportion of nutrient elements and changes in soil nutrient structure caused by long-term use of compound fertilizers containing only major elements, and has high social, economic, and ecological benefits.
