Abstract

The effectiveness of sewage sludge as nutrient source was studied under greenhouse conditions using a Typic Haplorthox/LE soil and sorghum as a plant test The levels of sewage sludge corresponded to applications of 0, 5, 10 and 20 tha-1. The parameters evaluated were sorghum dry matter, nutrient uptake and soil fertility. The results showed that the sewage sludge supplies N, P, Ca, Mg and S to plants. K addition to the sewage sludge is necessary to supply the need of the sorghum plant.
