Now a day the soil fertility of high land areas, where most of the agricultural activities have been done at the escarpments of the landscape, has been decreased. These in turn decrease the productivity of land because of the removal of soil and nutrient by erosion. Therefore the use of fertilizer has increased to compensate the removed nutrients through erosion. The change in land use is also another factor to increase or decrease the fertility of the land. The application of the same fertilizer rate at each landscape position lead us wastage or inefficient. This book, therefore, provides the variability of soil chemical fertility among different land use and landscape position, as well as soil deterioration indices. The analysis help some light on this variability, and especially useful to professionals like researchers, agriculture experts and instructors etc working in areas of soil fertility and decision makers who may use fertilizer in the high land areas or any else.
