Translation of "soil" into Basque

‘Earth’ as ‘soil’ (but not as a specialized professional term, e.g., Eng. ‘soil’ itself). To be separated from ‘ground’ (= ‘surface’), ‘land’ (= ‘dry land’ or ‘property’), etc. Also to be separated from specific kinds of soil (‘red earth’, ‘black earth’, ‘clayey soil’ etc.). Contexts are the same as in No.71 ‘sand’.

The top layer of the land surface of the earth that is composed of disintegrated rock particles, humus, water and air.
