Abstract
Abstract The aim of this study was to investigate the effect of biochar and wheat straw on nitrogen leaching and corn yield. Field experiment includes CO (control treatment), SM5 and SM10 (wheat straw with a thickness of 5 and 10 mm, respectively), ST5 and ST10 (wheat straw at a rate of 5 and 10 t ha −1 in combination with soil, respectively) and BT2.5 and BT5 (biochar at a rate of 2.5 t ha −1 in combination with soil). Results showed that the total amount of leached nitrate in BT5, SM10, BT2.5 and ST5 treatments decreased by 71%, 55%, 50% and 32%, respectively, compared to CO. Also, the increasing biochar application rate (BT5) led to enhance 28% in maize grain yield and reduce deep percolation, nitrate and nitrite leaching by 31%, 71% and 97%, respectively. Therefore, it seems that the use of bioshar and straw reduces nitrate leaching, improves soil moisture conditions and increases corn yield.
