资源简介:
Extractable aluminium content (Al measured by Mehlich 3) in mg/kg (fine earth) at 2 depth intervals (0-20 cm and 20-50 cm) 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)
本数据集包含基于两套非洲土壤剖面数据预测得到的可提取铝含量(以梅利奇3法(Mehlich 3)测定,单位为mg/kg,以细土粒(fine earth)计),覆盖两个深度间隔:0-20 cm与20-50 cm。详细信息请参阅下述已发表论文:Hengl T.、G.B.M. Heuvelink、B. Kempen、J.G.B. Leenaars、M.G. Walsh、K.D. Shepherd、A.
