Abstract
Assessment of agro potential of sugar industrial sludge
Author(s): P.V. S. Machiraju, Y. L. N. MurthyThe study of physicochemical parameters of sludge from sugar industry in which the observed percent Sodium (14.45 me/L) and SAR value (3.78 me/L) were found to be well within the permissible limits indicating its suitability as a landfill for irrigation purposes. The ratio of Nitrogen to potassium is found to be 17.53:1, while the phosphorus content is at below detectable limit. Hence as a land fill material it can partially replace the commercially used nutrient formulations. The presence of macro-nutrients such as calcium (1070 mg. Kg-1) and Magnesium (2156 mg. Kg-1) is a valuable input for effective utilization of this sludge for irrigation purpose. In our present investigation the heavy metal concentrations are well below the permissible limits and hence cause no concern. The present studies have been carried out on germination and seedling growth of four vegetable crops to assess the agro potential of the sludge.
