Grazing of units 5b, 5c, 5d and 5e should be restricted when the soil surfaces are waterlogged or inundated. Ex cessive puddling from cattle hooves during the wet season will damage paatures and'cause compaction of the surface.

The surface of the shallow yellow earths is erodible if unduly disturbed, but the problem is not so great for the Ii thosols which have a surface gravel veneer. These areas are suitable for improvement with annual 'species (e.g. Townsville .. Stylo). The lithosols of unit 3bl and the shallow yellow earths of unit 4b2 have a low moisture holding capacity, but also suffer inundation for short periods. Annual species tolerant of such inundation would be suited to these conditions. Units 4a, 4b, 4bl and 5a have moderately deep to deep soils whose major limitation is surface waterlogging'for in creasing periods. during the wet season. In addition, erosion becomes a greater hazard for the units in the same order 4a, 4b, 4bl and 5a because of run-off from higher slopes. The moderately deep yellow earths of unit 4a have least limitations because they 'are moderately well drained, ex perience only slight waterlogging and receive very little run-off from higher slopes.. Lower in the topographic sequence where unit 4b is imperfectly drained, yellow earths ,
