Abstract

The mineralization of several N-compounds, such as MMU, DMU, and HMT, as well as their respective nitrificide action, have been investigated. It has been proved that the amount of available formaldehyde, as well as its rate of release, are responsible for the specific action of these compounds on the N-mineralization process. Factors affecting the rate of release, namely molecular structure, solubility, and temperature, are discussed as well. Importance of these N-compounds as slow-release N-fertilizers based on a new molecular-microbiological approach is described.

摘要

已经对几种含氮化合物(如MMU、DMU和HMT)的矿化作用及其各自的硝化作用进行了研究。事实证明,有效甲醛的量及其释放速率是这些化合物对氮矿化过程产生特定作用的原因。还讨论了影响释放速率的因素,即分子结构、溶解度和温度。描述了基于一种新的分子微生物学方法,这些含氮化合物作为缓释氮肥的重要性。
