The behaviour of available phosphorus and its relationship with plants in acid volcanic soils of the Canary Islands

A study of multiple components, followed by discriminant analysis, distinguished two basic main groups of acid volcanic soils in the Acentejo District in the north of Tenerife (Canary Islands): desaturated Andisols and Alfisols. Available P (determined by the methods of Olsen and Dyer) and exchangea...

Sumario:A study of multiple components, followed by discriminant analysis, distinguished two basic main groups of acid volcanic soils in the Acentejo District in the north of Tenerife (Canary Islands): desaturated Andisols and Alfisols. Available P (determined by the methods of Olsen and Dyer) and exchangeable Al extracted with 1n NH$OAc (pH 4.8), and 1n KCl were used as variables. Plant uptake of P depended on the amount of available P (Dyer method) in the Alfisols, and on available P (Dyer method) together with exchangeable Al (KCI) in the desaturated Andisols.
