ABSTRACT
The problematic soils need to be classified in to various groups for developing special systems of management for specific types of problems and constraints in the production of crops. Soils, in which concentration of salts is so high as to adversely affect plant growth and crop productivity, are called salt affected soils. The extent of reduction in growth and decrement in productivity, however, depend upon many factors such as kind and content of salt constituents, soil texture, distribution of salts in the soil profile, the species of plant grown, level of soil - water - crop management and climatic condition. The reclamation of acidic soils is done by addition of liming material which may be calcitic limestone or dolomitic limestone. Management and reclamation of calcarous soil are not difficult because pH in such soil is not very high. Generally, there is no need of chemical amendment for reclamation of calcareous soil.
