Soil Horizon Descriptions/Classification and Lab Analysis

Characterization and sampling of Bonanza Creek Long Term Ecological Research site soils was done. Characterization included description of the soil pits and the horizons. Measurements of pH were taken and sampling for bulk density, bulk chemical/physical characterization, and P-fractionation occurred. Soil classification was also determined.本研究完成了博纳泽溪长期生态研究站（Bonanza Creek Long Term Ecological Research）区域土壤的表征与采样工作。土壤表征工作涵盖土壤剖面坑与土壤发生层的描述；完成了土壤pH值的测定，并针对土壤容重、整体化学与物理性质表征以及磷组分分级开展了采样工作；同时完成了土壤分类的判定工作。
