It is an advanced nitrification inhibitor with high efficiency, safety and non-toxicity in the world, and it is also an environmentally friendly nitrification inhibitor with high cost performance. The effective period of ammonium nitrogen can be extended from 25 days to more than 50 days, and the utilization rate can be increased from 30% to more than 40%.
DMPP has the following characteristics:
1, will not produce toxic effects on plants.
2. Completely decomposed in soil, and the final decomposition products are phosphate, water, carbon dioxide and nitrogen oxides.
3. There is no residue in the harvested agricultural products.
4. There is no risk to soil, microorganisms, water, people and animals.
5. There is no leaching phenomenon in the soil.
6, no irritation to human skin and eyes.
7, the dosage is low, and the same effect can be achieved when the dosage is only 1/15 of dicyandiamide.
Efficacy: DMPP can inhibit the activity of nitrifying bacteria in soil, delay the transformation of ammonium nitrogen to nitrate nitrogen, help to increase the adsorption capacity of ammonium nitrogen in soil, prolong the retention time of available nitrogen, prolong the fertilizer efficiency and improve the utilization rate of nitrogen fertilizer. Scope of use: mixed with ammonium nitrogen and amide nitrogen fertilizer in limited amount to produce stable nitrogen fertilizer, stable compound fertilizer and water-soluble fertilizer.
Addition amount: DMPP (pure) is added according to 0.5%-1.0% of the total amount of ammonium nitrogen and amide nitrogen in the fertilizer.
