| dc.description | Biochar incorporation into soils influences many of the soil‟s physical/chemical properties. The potential of using biochar for reclamation of saline-sodic soils is not well evaluated. Furthermore, how salinity would influence Phosphorus (P) sorption capacity of biochar is not clear. The main goals of this research were to determine the possibility of using biochar on amelioration of a saline-sodic soil and reduce the loss of P from soils, and to evaluate how growth and yield of wheat responses to a biochar amended saline-sodic soil. The biochars used in this research were produced from wheat straw, hardwood, and willow wood at pyrolysis temperature ranged between 500 and 550 °C. The used soils were sampled from the plow layer (0.1 m) of saline-sodic and non-saline soils of a local farm in Alberta, Canada. The influence of salinity and biochar type on P sorption by biochar was evaluated through a P sorption isotherm experiment. The hardwood biochar was selected as a soil amendment for followed experiments based on its high P sorption capacity. The effect of biochar application at different rates (0, 2, 5 and 8% [w/w]) on reducing salinity and leaching loss of P was evaluated using column leaching experiments. The 0 and 5% of biochar application rates were selected to evaluate the growth and yield of spring wheat in a pot experiment. The responses of the crop to biochar, manure and soil type treatments were evaluated by measuring plant nutrient contents and plant growth and productivity. | |
