Abstract
- Amending soil with different materials is gaining acceptance as an effective and inexpensive technique for reclamation of salt-affected soils. The main idea of this study was to investigate the effects of biochar, compost of municipal solid waste and different water salinities level on soil physical quality (S<subscript>Dexter</subscript>) and soil productivity index (SPI). The treatments were as followed: Control: Soil without biochar or compost and irrigated with tap water, S1: Soil without biochar or compost and irrigated with saline water (EC = 4.5 dS m<superscript>−1</superscript>), S2: Soil without biochar or compost and irrigated with saline water (EC = 9 dS m<superscript>−1</superscript>), B: Soil amended with 1.5%w/w biochar and irrigated with tap water, B+S1: Soil amended with 1.5%w/w biochar and irrigated with saline water (EC = 4.5 dS m<superscript>−1</superscript>), B+S2: Soil amended with 1.5%w/w biochar and irrigated with saline water (EC = 9 dS m<superscript>−1</superscript>), C: Soil amended with 1.5%w/w compost and irrigated with tap water, C+S1: Soil amended with 1.5%w/w compost and irrigated with saline water (EC = 4.5 dS m<superscript>−1</superscript>), C+S2: Soil amended with 1.5%w/w compost and irrigated with saline water (EC = 9 dS m<superscript>−1</superscript>). Soil water characteristic curve (SWCC), Field capacity (FC), Plant wilting point (PWP), Plant available water (PAW), Dexter's index of soil physical quality (S<subscript>Dexter</subscript>) and SPI were examined in a greenhouse experiment. The SPI was calculated by integrating the effects of six soil quality indices: plant available water, organic matter (OM), Electrical conductivity (EC), pH, Bulk density (BD) and Root weighting factor (RF) for all treatments were calculated. The results showed that the B treatment had a slightly higher effect on SWCC. The applied B and C treatments caused insignificant increase in PAW relative to the control. In addition, application of biochar or compost to soil significantly increased the S<subscript>Dexter</subscript>. The application of C treatment had insignificantly higher value of S<subscript>Dexter</subscript> compared to other treatments. Compared with the control, SPI was significantly higher for the B and C treatments. Overall, the application of biochar/compost minimized the destructive effects of saline irrigation water and improved the quality of the salt-affected fine-textured soil. [ABSTRACT FROM AUTHOR]
