Urease inhibitor is a kind of substance that can inhibit the activity of soil urease, and it is a new technology which has been studied in urea or nitrogen compound fertilizer. Using soil urease inhibitor can effectively slow decomposition of urea into ammonia process, reduce soil NH4 + and NH3 concentration, soil fertility and crop fertilizer synchronization.

N-(n-propyl) thiophosphoric triamide was synthesized by "one-pot" method. Using the phosphorus sulchoride and n-propylamine as raw material, the intermediate is synthesized by nucleophilic substitution reaction. Then, the intermediate isreacted with ammonia by ammonolysis to synthesize the N-(n-propyl) thiophosphoric triamide. The purity of product was 97.5%, overall yield of 76.6%.

Based on the principle of soil colloid adsorption of ammonium ion addition of nitrification inhibitor DMPP in fertilizer, control of ammonium into nitrate, and you realize a stable supply of nitrogen, reduce the leaching loss of nitrate,nitrogen oxide emissions, in order to improve the utilization rate of chemical fertilizer, Protect environment, promoting agricultural development objective. DMPP use plant absorption enhancing effects of ammonium nitrogen and nitrate nitrogen, obtain synergistic benefits, in reducing nitrogen and also improve crop yield.

3,4-Dimethylpyrazole (phosphate) (3,4-DMPP) is an inhibitor of nitrification deemed safe by extensive standard toxicology and ecotoxicology tests. 1When utilized oncrops, 3,4-DMPP prevents nitrogen loss from soil, increases nitrogen use efficiency, and boosts crop yields. However, a meta-analysis found no influence of 3,4-DMPP on net crop yield, although it may boost yields in alkaline soil. 3,4-DMPP may be less effective in acidic soils and in the post-harvest period. DMPP interferes with ammonia monooxygenase from ammonia-oxidizing bacteria (AOB) and archaea (AOA) but may not directly affect AOB, AOA, and non-target populations.

Known as the first plant growth retardant to be used on plants, Chlormequat Chloride was first discovered by chemistry professor Dr. N.e. Tolbert at Michigan State University in the late 1950s. Dr. Tolbert first experimented with wheat crops, to which he applied Chlormequat Chloride. His experiments resulted in thicker stems and shorter plants.Nowadays, Chlormequat Chloride is commonly used in nurseries to slow down stem growth while encouraging flowering in ornamental plants and flowers. In addition to Chlormequat Chloride, Paclobutrazol and Daminozide are similar plant growth regulators (PGRs) that are present in a number of popular products on the market and are used by a significant percentage of growers in the indoor gardening industry.

Phosphorous acid is the compound described by the formula H3PO3. This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds.

Monopotassium phosphite is an inorganic compound with the formula KH2PO3. A compositionally related compound has the formula H3PO3.2(KH2PO3). Both are white solids that contain salts of the phosphite anion H2PO3−, the conjugate base of phosphorous acid. These materials have been used in some fertilizers.
