Short summary
Sodic soils affect ~580 Mha in semi-arid and arid regions of the world. These soils have a weak structure. This laboratory study evaluated treatments to overcome the weak aggregate structure in two sodic Vertisols by applying organic amendments, gypsum, and wetting–drying cycles. We conclude that sodic soils need to be treated with gypsum to flocculate clay and organic amendments (lucerne or chicken manure) to form aggregates, whereas drying cycles aid in small macroaggregates formation.
