More Information
Summary:The invention discloses a combined material and method for rapidly reducing the pH of soil, the combined material comprises the following components in percentage by mass: 80-95% of a sulfur-containing substance and 5-20% of a phosphorus-containing substance, and the sulfur-containing substance comprises one or more of sulfur, ammonium bisulfate and sulfamic acid materials. The phosphorus-containing substance comprises one or more of ammonium dihydrogen phosphate, sodium dihydrogen phosphate and phytic acid, and the combined material provided by the invention can be quickly oxidized to generate a large amount of H < + > or directly release H < + >, so that a strong acid environment is formed, and soil acidification is intensified. The actual quantity of the sulfur-containing and phosphorus-containing combined material which should be added within an expected soil pH range can be calculated through a soil simulation test, then the sulfur-containing and phosphorus-containing combined material is applied to farm
