Conteúdo: | Soil; Samples obtained from genetic horizons of an upland and acid sulphate soil of Sierra Leone, were equilibrated with 0.01 M CaCl2 using a 1:2 to solution ratio. Al activity was estimated from total Al measured in the equilibrium extract, by accounting for hydrolysis and the formation of other complex species. The Al activity was pH-dependent, but the Al(OH)3 ion product was fairly constant throughout the upland soil profile; Al activity was near that expected for equilibrium with kaolinite and quartz. In the acid sulphate soil alunite appeared to control the activity of Al.
