Therefore, this study aims to examine changes in parameters of soil physical properties on various slopes due to the provision of types of organic matter (manure, coffee skins and <em>Gliricidia</em> leaves). This study also analys the influence of slope soil to the Napier grass production (<em>Pennisetum purpureum</em>). The study was obtained in the hilly areas of Paya Tumpi Village by using a <em>split plot organic design</em>. In deep analysis of change in parameters on the slope of the type of organic material on soil physics will be performed. The results showed that organic various types of slope and administration of various types of organic materials significantly affected the physical properties of the soil, namely permeability, porosity, aggregate stability index, fast drainage pore, slow drainage pore, available water pore, growth and yield of Napier grass. <em>Gliricidia</em> leaves compost is the best for growing Napier grass.</p> Erita .

Among the various amendments, compost prepared from the crop residues attracted much attention in recent years. The crop residues used as feedstock are added with different bulking materials such as rice husk and sewage sludge.&nbsp; In addition to these, termite mound soil which is available in plenty in tropical countries is found to be a suitable bulking material and is added with crop residues to obtain nutrient rich compost. In this paper we reviewed researches carried out on the characteristics, microbial diversity and organic matter degrading enzymes in termite mound soil. Further, the research carried out on the characteristics of compost amended with termite mound soil and its effect on crop productivity is also reviewed with the available literature. Majority of the investigations concluded that termite mound soil possessed more microbial population with a huge array of organic matter degrading enzymes. Few studies monitored the nutrient content of the soil and water holding capacity of the soil and crop yield when termite mound soil was used as a soil amendment. Limited studies were conducted using termite mound soil as a bulking material to compost crop residues. Based on the outcome of various studies, it is understood that the termite mound soil might be used as a soil amendment to increase growth and yield of crops.</p> S. Subi A.
