摘要: Abstract Adsorption of sulphate was studied on eight West Indian soils. dependent concentration for all the soils studied. At low concentrations dissolved sulphate, amount adsorbed in accordance with Langmuir equation. higher this relationship broke down and it is postulated that due to differing adsorption sites. In desorption studies, released decreased each successive extraction. Only 32.7% 76.4% initially recovered four KH2PO4 extractions from Montserrat clay Montreal sandy loam, respectively. This ascribed different properties two Sulphate related percentage NaOH-extractable aluminium soil.
