The formation of a gley is known as gleying.

育层是育作用形成的。

Where this layer is sufficiently impermeable to maintain the A horizon in a waterlogged condition, the soil is termed a gley podsol.

淋溶层B高度的不透性保持淋溶层A处于浸状况，这种壤称为灰壤。

The paddy soil probably had a long history of tillage, and furthermore it had formed gley horizon and illuvium, but its fertility was not high either.

有较长耕作历史，并已形成育层和潴育层，但壤肥力并不高。
