| titleOfInvention | Humic acid-type calcium-magnesium-sulfur soil conditioner and its preparation method |
| abstract | The invention provides a humic acid-type calcium-magnesium-sulfur soil conditioner. The soil conditioner takes 17-30wt% of humic acid, 50-67wt% of desulfurized gypsum, 2-4wt% of ammonium sulfate, 2-3wt% of urea, and 7-13wt% of a magnesium fertilizer as the raw materials for processing and production. According to the requirements of the soil conditioner, a organic matter content is greater than or equal to 15.0%, total nitrogen is greater than or equal to 2.0%, calcium oxide is greater than or equal to 13.0%, magnesium oxide is greater than or equal to 2.0%, sulfur is greater than or equal to 8.0%, a water content is less than or equal to 15.0%, and the pH of the soil conditioner is 4-6.5. The soil conditioner of the invention contains abundant organic matters, active groups, available nitrogen, exchangeable calcium, magnesium and easily absorbable sulfur element. While improving saline-alkali soil, the soil conditioner can provide nitrogen and calcium, magnesium, sulfur as well as other secondary elements to crops in a balanced way. The soil conditioner provided in the invention can significantly improve the physiochemical properties of saline-alkali soil, promote crop growth, as well as improve and enhance crop quality and yield. |
