soil profile

The distribution of the heavy mental elements (HMEs) in eluvial horizons, illuvial horizons and parent material horizons of 26 agricultural soil profiles in Hainan Island was studied.

场样及室内分析测试方法,对海南岛26个农业土壤剖面淋溶层、淀积层、母质层中7种重金属元素分布征进行研究。

This site offers images from the tropics e.g. pictures of soil profiles: aridisol in Peru, vertisol in Kenya, alfisol in Nigeria, mollisol in Thailand, spodosol in Brazil, laterite outcrops etc.

该站点提供大量热带土壤剖面图，如：秘鲁旱成土、肯尼亚变性土、尼日利亚淋溶土、软土、巴西灰土、红土岩层等。
