Investigation of Usage Samples of Treatment Sludges in Agricultural Areas

Abstract

Nowadays, due to some reasons, soil quality deteriorates, soil organic matter decreases, and plant growth is adversely affected such as damaging agricultural practices, unconscious pesticide and fertilizer use. There is also treatment sludge among the methods that will contribute to the soil. Sewage sludge, the inevitable by-product of municipal and other wastewater treatment plant operations, is a key issue in many countries due to its increasing volume and the impacts associated with its disposal. This environmentally hazardous treatment sludge can be significantly reduced by anaerobic digestion. However, the resulting gas and the residues from anaerobic digestion process need to be treated or stabilized. The use of sewage sludge in agriculture will provide both soil nutrient elements and waste sludge can be disposed with this application. Definitely, it is possible to evaluate the treatment sludges in many different areas. After cleaning the sludge from contaminants, it can be used as a good compost or soil improvement material. In this study, agricultural applications with sewage sludge were investigated.
