Short-Term Effects of Sewage Sludge Compost Application on Some Chemical Properties of Sandy Soil

Abstract

The application of sewage sludge compost in agricultural soils has a dual interest. This allows preserving nature and improving the soil quality by supplying plant nutrients. A field experiment was carried out to evaluate the effect of different amounts of sewage sludge compost (0, 20, 40 and 60 t ha−1) on chemical soil properties. The considered soil depths are (0–20; 20–40 and 40–60 cm). OM, N, P, K, pH, CE determination followed amendment with sewage sludge compost. The results indicated that the evaluated chemical soil parameters were changed by the application of this biosolid. In addition, sludge application increased the organic status of the soil and nutrients.
