Using Of Pumice And Corbonification Sludge For Sustainable Agriculture

Abstract

The recovery of wastewater sludge in agriculture is an opportunity for minimization of waste. Sustainable production approach will be provided by using sugar wastes in agriculture. The aim of this study is to research the effects of sugar industry sludge and pumice on soil properties and the plant growth characteristics as a soil conditioner. For this purpose, a greenhouse experiment was conducted on the soil samples taken from three different locations in Konya where the corn is a primary crop grown. The experiment was established in randomized plots experimental design with three replications. The sludge and pumice were mixed into the soil at four doses (0, 40, 80, 160 tons/ha). The silage corn, Pionner 32K61 variety, were used as a test plant. After the harvest, the growth characteristics of corn, such as plant height, plant weight, stalk diameter, stalk weight, number of leaves, leaf weight, leaf dry matter and stalk dry matter were determined. The relationships between the treatments and some plant growth characteristics were evaluated by statistical analysis. Statistically significant relationships were found between the treatments and growth characteristics. The soil properties determined were much better than control application with increasing doses in the three soil samples. The highest productivity was obtained in Atlantı and Hayıroğlu soils with pumice of 160 tons/ha dose, in Karapınar soil with pumice + sludge of 160 tons/ha dose.
