ABSTRACT
ABSTRACT: The objectives of this study were to investigate soil type, potentiality and reaction in relation to the scattered remaining vegetation species, and to quantify soil suitability for growing field crops. Adham area witnessed serious land degradation due to the rapid expansion of Rain-fed Mechanized Farming and overgrazing. Consequently, the low crop yield enforced the local communities to shift to the alternative sources of income generating activities, particularly those related to forest products like charcoal making, firewood production, logging and tree lobbing. By using Randomized Complete Block Design (RCBD), with emphasizes on Macro nutrients, particularly the Nitrogen, Phosphorous and potassium (NPK) in addition to soil pH and Electrical Conductivity (EC.), random soil samples, each with three levels of depths (0 - 15, 15 - 30, 30 - 45 cm.) were collected. All collected data were analyzed in the laboratory. The result of revealed several types of soils including the cracking and non -cracking clay, sandy, and red soils. The result of statistical analysis depicted variability in NPK, pH and EC between the different locations and soil depths. Furthermore, the result showed an association between some studied soil attributes and the spatial distribution of the vegetation species. Rational use through participatory approach is recommended for natural resources management, conservation and sustainability. Moreover, further study using space technology also recommended.
