Abstract/ Executive Summary:

A considerable amount of research work has been conducted in different countries of the world on soil acidity complex. In this paper an attempt has been made to review some of the pertinent research on the complex factors of soil acidity affecting the growth of plants. The major factors responsible for poor plant growth in acid soils are the presence of excess amounts of hydrogen ion concentration, exchangeable aluminum and manganese; the deficiencies of phosphate, calcium, magnesium and molybdenum. In addition to these factors plant species and varieties vary widely in their sensitivity or tolerance to the factors of soil acidity.
