Background and aims Biochar is produced from the pyrolysis of organic materials, with the characteristics of high carbon concentrations, porous structure, huge specific surface area and various functional groups. When buried into soil it can act as a long term soil carbon store. Evidence suggests that biochar can improve plant growth, increase crop yields, reduce nutrient leaching and stimulate microbial activity. Moreover, as a soil conditioner, biochar can significantly improve soil fertility. But few data have been obtained on the impacts of biochar on salt leaching of saline soil. Therefore, the aim of this study was to investigate the effect of biochar on leaching of salts and ions from the saline soil.
Methods In this experiment, different rates of mushroom medium biochar (0%, 2%, 5%, 10%, w/w) were added into 0-20 cm surface soil in a sulfate saline soil column collected from Hetao Inner Mongolia. Following washing with deionized water, the eluent was collected and measured for electrical conductivity (EC) and main ions. At the end of the leaching, the contents of main ions in the leached saline soil profile added with different rates of biochar were also measured.
Results The results showed that the eluent from biochar-amended columns appeared much earlier, by 5~36 days ahead. The duration of EC redu ... 전체 초록 보기
