    Abstract

    Nitrogen is the main problem in soil, one of them is nitrate compound is water soluble and easy to be leached in the soil water and become pollution substances in the soil and water. The research aim is to study about the potential of trees litter in agroforestry system were estimated have the natural nitrification inhibitory effect and heterotrophic microbe in the soil. This research was conducted by survey and usingdestructivesoil sampling. The nitrification potential in the soil was measured by Berg and RosswallMethod modification from Kandeler, population and activity of the nitrifying microbe using MPN method, and population of the heterotrophic microbe by using Plate Count method.Result of the research are : the all treeslitter observed in the study candecline the nitrification rate, potential nitrification value and increasing the amount of Heterotrophic Bacteriasignificantly. The using the litter of plants can be recommended as an alternative way in controlling nitrification process naturally, environmental safety and supporting continuous agriculture system.
