SoilGrids250m 2.0 - Total nitrogen aggregated 1000m

Total nitrogen in cg/kg at 6 standard depths. Predictions were derived using a digital soil mapping approach based on Quantile Random Forest, drawing on a global compilation of soil profile data and environmental layers. This map is the result of resampling the mean SoilGrids 250 m predictions (Poggio et al. 2021) for each 1000 m cell.

本数据集涵盖6种标准深度下的总氮含量（单位：厘克/千克）。其预测结果基于分位数随机森林（Quantile Random Forest）的数字土壤制图方法生成，所用数据源自全球土壤剖面数据集与环境图层汇编。该成果为将SoilGrids 250米分辨率的平均预测结果（Poggio等，2021）重采样至每1000米格网后的产物。
