Abstract
A study was made on phosphorus fractions from six profile collected from
laterite soil (Oxisols) series identified in different regions in Kerala. Fe-P formed
the predominant among the active fractions on all the soils investigated except
Nenmanda and Thonnackal series indicating their highly weathered nature. This
was followed by Ca-P and AI-P respectively in the case ©f Anjur, Kanjikulam and Mannur series. In Kootala series, Fe-P was followed by AI-P and then Ca-P.
Thonnackal series showed a predominance of Ca-P followed by Fe-P and then AI-P.
