英文摘要 | onsThe changes of hydraulic properties of desert soil were attributable to the biochar properties. PurposeThe objective of this study was to investigate the effects of amendment of different biochars on the physical and hydraulic properties of desert soil.Materials and methodsBiochars were produced with woodchip, rice straw, and dairy manure at temperatures of 300 and 700 degrees C, respectively. Each biochar at 5% (w/w) was mixed with desert soil, and the mixtures were incubated for 120days.Results and discussionThe different biochar treatments greatly reduced soil bulk density and saturated hydraulic conductivity. Especially the rice straw biochar addition resulted in the lowest saturated hydraulic conductivities among the treatments. Biochar addition significantly increased water retention of desert soil at any suction. At the same suction and experimental time, the treatment with the rice straw biochar produced at the lower temperature resulted in higher water content than the other treatments. The biochar additions slightly enhanced formation of soil macro-aggregates in the early experimental time. However, the aggregate contents gradually decreased with time due to the lack of effective binding agents (e.g., soil organic matter and clay minerals).ConclusiThe higher fine particle content, porosity, and surface hydrophilicity of rice straw biochars were the most beneficial properties to increase soil water retention and to reduce water flow in the desert soil. The improvement of hydraulic properties by biochar addition may provide a potential solution to combat desertification. |
