Soil texture classes (USDA system) for 6 soil depths (0, 10, 30, 60, 100 and 200 cm) at 250 m

Derived from predicted soil texture fractions using the soiltexture package in R. Processing steps are described in detail here . Antartica is not included.

250米处6个土壤深度（0、10、30、60、100和200厘米）的土壤纹理等级（美国农业部系统）。

使用R语言中的土壤质地包，从预测的土壤质地分数中得出。南极洲不包括在内。
