The albic soils (baijiantu) is develop.nent under semi-humid climate of temperate none in this country. They are commonly derived from Quaternary deposits. Due to periodically stagnancy of water under conditions of alternate seasonal wetness and dryness, the iron and manganese are reduced and leached off, the clay fraction is also leached downward, its amount apparently decreases in A and SB horizon, but increases in the B horizon. Silicon-iron, silicon-aluminium, and silicon-iron-aluminium ratios change insignificantly in the entire soil profile.The soil acidity is stable, the base saturation is high generally around 70-90%.
