Abstract by author:
The study has taken into account all factors contributing to soil formation, soil fertility, agricultural potential and the agricultural practices taking place on the soil vegetation, rainfall and climate. Farming practices i. e. crop and livestock which are interrelated to soil are also covered
Therefore this piece of information is surely not something you can miss like one reader has said "It is really informative and something you cannot miss whether you are a farmer; student of soil science, agronomy or forestry"
