Abstract

The use of cheap adsorbents, such as hydrochar and biochar, is important for protecting the environment (preventing water pollution by nitrates). For this purpose, this research was carried out at research farm of Faculty of Water Sciences Engineering, Shahid Chamran University of Ahvaz in 2018. The treatments of this research were modified hydrochar and biochar in three levels of 0 (control), 2 and 5 g / kg soil in 4 replicates. After preparing the hydrochar and biochar from sugarcane bagasse, mixing these materials with loamy soil and put them into test tubes, Urea fertilizer was applied in irrigation 1, 6 and 12 (from 15 irrigation) to soil columns. This experiment was conducted in a randomized complete block design with two independent experiments. At the end of each irrigation, nitrate output was measured. The results showed that the effect of 5 grams of biochar treatments on all irrigation and 5 grams of hydrochar, except irrigation 4 and 6 at 5% level, was significant on Nitrate leaching. 2 g of biochar treatment showed better performance than 2 g of Hydrochar in all experiments. Treatment of 2 and 5 g of biochar per kg of soil were 30 and 43% respectively, and treatment of 2 and 5 g of hydrochar per kg of soil, were 20 and 31%, respectively, was effective in preventing Nitrate leaching.
