The land is limited entity of the country, which compel us to increase production and productivity of land per unit area and to rehabilitate the problematic soil for crop production, forestation and to maintain friendly ecosystem. In our country land is subjected to various types of degradation out of which 9.38mha suffered from sodicity and alkalinity. It is developed by accumulation of excessive salts in upper surface of soil. Sodic soil has high concentration of CO3,HCO3 and excess of Na on the exchangeable site of clay particles. They are deficient in nitrogen, phosphorous and zinc such soil has high pH (greater than 8.5, sometime upto 10.7) and poor soil structure. The nitrogen fixing ability of tree legume allows them to grow on difficult sites subject to erosion, low fertility or other adverse soil conditions. Once established they can create conditions favorable for the growth of other species leading to balanced plant ecosystem. The work represented in this book is significant in understanding morpho-physiological and biochemical features of the test plants and their contribution in bioreclamation of degraded (sodic) soil through improvement in its physical character.
