Soil particle distribution data

This Excel file contains data on the mass proportions of soil particles across different size classes including unimodal, bimodal, trimodal, and irregular modal distributions, along with soil texture data using the USDA triangle (sand, silt, clay).本Excel文件包含不同粒级土壤颗粒的质量占比数据，涵盖单峰、双峰、三峰及不规则峰态分布类型，同时附带采用美国农业部（USDA）土壤质地三角图法（砂粒、粉粒、粘粒）得到的土壤质地数据。
