控制土壤侵蚀的主要因子用USLE公式表达。方程中C因子表示栽培制和耕作措施。这项研究将与C因子值有关系的耕作时间和耕作次数联系起来。使用降雨模拟器,根据所测的径流、土壤流失和土粒大小(分散的和不分散的)估价各项试验结果。然而,因为侵蚀方面知识的进展,这就需要更加深刻了解C因子中每个亚因子的影响。这些亚因子包括耕作、覆盖、冠层和它们的残茬影响。
The main factor controlling soil erosion is expressed by the formula of USLE. The C factor in the equation indicates cultivation and tillage practices. This study relates tillage time to tillage times associated with factor C values. Rainfall simulators were used to evaluate the results of the tests based on measured runoff, soil erosion and soil size (both dispersive and non-dispersive). However, because of the advances in knowledge on erosion, this requires a deeper understanding of the impact of each sub-factor in the C-factor. These sub-factors include tillage, cover, canopy and their residual effects.
