Product Description

Slow-release nitrogen fertilizers are also known as long-acting nitrogen fertilizers or controlled-release nitrogen fertilizers.
Refers to nitrogen fertilizers that slowly release effective nutrients due to changes in chemical composition or surface coating with semi-permeable or impermeable substances to maintain a longer fertilizer efficiency. The most important feature of slow-release nitrogen fertilizer is that it can control its release rate. After being applied to the soil, it gradually decomposes and is gradually absorbed and utilized by crops, so that the nutrients in the fertilizer can meet the different needs of various growth stages in the entire growth period of crops. After one application, Fertilizer efficiency can be maintained for several months to more than a year.

Long-term field experiments and research results show that, under normal circumstances, after nitrogen fertilizer is applied to the soil, only 30-50% of it can be absorbed and utilized by crops, while the rest is lost in vain. The loss of nitrogen fertilizer is due to the volatilization of . Leaching, nitrification and denitrification. The purpose of developing and applying slow-release nitrogen fertilizers is to reduce the dissolution rate of nitrogen fertilizers, so that nitrogen fertilizers can successively provide nitrogen to crops during the slow-dissolution process, and prevent adverse consequences such as damaging crop seeds, seedlings or burning leaves due to excessive local concentration during large-scale application. , in order to achieve the purpose of improving nitrogen utilization efficiency.
