Abstract Biochar is known to improve soil physical properties, but its role in influencing soil erosion and nutrient losses, as well as biochar itself loss is poorly understood. The objectives of this study were to determine the magnitude of soil, biochar and nitrogen losses in runoff and quantify the degree of sediment enrichment with biochar and nitrogen in a soil amended with biochar. A loessial soil was amended with five rates of nitrogen-rich biochar [0, 1%, 3%, 5%, and 7% (w/w)] that had

模拟降雨下用生物炭修正的黄土径流中的土壤、生物炭和氮流失

摘要 众所周知，生物炭可以改善土壤物理性质，但其在影响土壤侵蚀和养分流失以及生物炭本身损失方面的作用却知之甚少。本研究的目的是确定径流中土壤、生物炭和氮损失的程度，并量化用生物炭改良的土壤中生物炭和氮的沉积物富集程度。用五种比例的富氮生物炭 [0、1%、3%、5% 和 7% (w/w)] 对黄土土壤进行了改良，这些生物炭具有
