Extract

A description is given of five typical soils of the Sudan covering a wide area. Of these, four are heavy clays and the fifth a sandy soil. All are alkaline and with one exception low in calcium carbonate. The results of the full chemical analysis of the conventional fractions are given and it is suggested that an important characteristic of a clay soil is the chemical composition of the clay fractions.
