资源简介:
Exchangeable acidity (H+Al measured in 1M KCl) in cmolc/kg (fine earth) at 6 standard depths predicted using two sets of Africa soil profiles data. For details see published paper here below (Hengl T., G.B.M. Heuvelink, B. Kempen, J.G.B. Leenaars, M.G. Walsh, K.D. Shepherd, A. Sila, R.A. MacMillan, J. Mendes de Jesus, L.T. Desta, J.E. Tondoh, 2015. Mapping Soil Properties of Africa at 250 m Resolution: Random Forests Significantly Improve Current Predictions. PLoS ONE 10(6)
本数据集为基于两套非洲土壤剖面数据集预测得到的6个标准深度层级的交换性酸度(采用1M氯化钾溶液测定的H+Al,单位为厘摩尔电荷每千克(cmolc/kg),基于细土组分)。详细信息请参阅以下已发表论文:(Hengl T.、G.B.M. Heuvelink、B. Kempen、J.G.B. Leenaars、M.G. Walsh、K.D. Shepherd、A. Sila、R.A.
