An effect of paper mill sludge in alkali soil reclamation

The disposal of industrial wastes is a problem of increasing importance throughout the world due to public health menace. Sludge from paper mills are produced in large quantities in most of the industrial countries of the world. Today due to the intensive usage of paper constitute one of our most serious environmental problems. Paper industries produce large amount of solids and its application increases the input of organic matter, and the availability of macro and micronutrients. The effect of paper mill sludge application on soil chemical properties is directly associated with the biological properties, vital for the nutrient turnover and long-term productivity. Hence, the present study was undertaken to examine the effect of paper mill sludge as an amendment in alkali soil and its influence on the growth and yield of green gram.
