EFFECTS OF SEWAGE SLUDGE ON SOME BASIC PRODUCTIVITY PARAMETERS OF SOIL

33835

This study was carried out in order to determine the effects of sewage sludge on some basic productivity parameters of soil. The research was conducted essentially by using “wheat + white head cabbage + tomato” crop rotation system and planned according to randomized blocks trial design. 0, 10, 20, 30, 40 and 50 t ha^-1 doses of sewage sludge and optimum recommended doses of chemical fertilizer composed of nitrogen (N) and phosphorus (P) were applied. It was determined that the pH of the soil decreased whereas EC, organic matter, total N and receivable P values increased with the increasing rates of sewage sludge. However, there was no variation on lime and receivable potassium (K) contents of the soil.
