More Information
Summary:Studies at home and abroad have also shown that nitrification inhibitors can slow the nitrification of nitrogen fertilizers in soil, thereby adjusting the supply form, supply time and supply amount of nitrogen fertilizers. [...]nitrification inhibitors are beneficial to crops' absorption cf nitrogen and trace elements, increase crop yield, improve crop quality, increase nitrogen fertilizer utilization, reduce nitrogen fertilizer application, and simplify fertilizer application[4-6]. [...]the effect of compound application of humic acid and DMPP was not the best at high concentrations, but was the best with high DMPP amount and low humic acid amount, while the effect was the poorest with low DMPP and low humic acid. Weathered coal is rich in humic acid and contains active groups such as carboxyl groups, phenolic hydroxyl groups, and sulfhydryl groups. [...]it has adsorption, complexation, and exchange properties, and can improve soil structure. The test results show that the combination has significant promoting effects on various biological indicators, all of which show significant increase from the single application. [...]the compounding at different concentrations of the 2 has different test results, and the effect is the best in the treatment adding 1 kg of DMPP and 5 kg of humic acid.
