报告摘要：

Soil health, as measured by the physical, chemical, and biological characteristics of soil, determines the yield potential of many crops and other ecosystem services. This presentation will cover the critical analysis of the literature data on the influence of biochar application on soil physical, chemical, and biological fertility, and presents the results of a meta-analysis of these data from publications. A treatment effect size estimator commonly employed in meta-analysis is the magnitude of an experimental treatment mean (i.e., with biochar application), relative to the control treatment mean (i.e., without biochar application). A typical effect size metric is the response ratio or the relative impact on a measured parameter (e.g., soil bulk density) following biochar application compared to that in control treatment. The results from the meta-analysis work have indicated that biochar application modulates physical, chemical, and biological properties of soils, and the extent of biochar-induced changes depends on the nature and level of biochar application, and soil type.
