This paper introduces a new method for determining exchangeable aluminum in acid soils. It discusses the importance of exchangeable aluminum in soil chemistry and the challenges in its quantification due to limited knowledge of non-exchangeable aluminum forms.
This paper summarizes the incidence of toxic aluminum in sandy soils, focusing on the response to lime treatments in Natal soils. It emphasizes the importance and widespread occurrence of aluminum toxicity in sandy profiles and discusses the analytical methods and findings related to labile aluminum in such soils.
