Evaluation of Modified biochar and Zeolite Effect on Some Physical and Chemical Properties of loamy Soil

The aim of this study was to investigate the effect of different levels of modified biochar sugarcane bagasse and potassium zeolite as natural and environmentally friendly fertilizers on some physical and chemical properties of soil in a completely randomized design with four replications for three months per year 2018 was conducted at the Faculty of Water Engineering, Shahid Chamran University of Ahwaz. The levels of biochar and zeolite use included three levels of 0, 2 and 5 grams per kg of soil (0, 0.2 and 0.5 wt%).The results showed that the 2 and 5 grams biochar per kg of soil increased the total porosity by 3.7% and 9.2% respectively, 9.6% and 19% moisture content of crop capacity, 1 and 1.5% moisture content of wilting point, 9.8% and 21.3% organic carbon, 9% and 18% of absorbable phosphorus, 8% and 22% of nitrogen, 6.5% and 27.9% of electrical conductivity , 3.3% and 8% respectively of bulk density and 0.26% 0.92 percent soil acidity. The levels of 2 and 5 grams of zeolite per kilogram of soil also increased 2 and 6 percent bulk density, 2.33% and 3.89% specific gravity, 10.1% and 26.5 percent moisture content, 1.1% And 6.3% moisture content of wilting point, 0.65 and 1.05% of acidity, 9.1% and 33.5% of electrical conductivity, 0.09% and 3.4% of total porosity, 0.26% and 0.92% respectively Soil acidity was not significant and did not have a significant effect on specific gravity, organic carbon, absorbable phosphorus and soil nitrogen.
