Ten soil smaples from cocoa estates were extracted with 10 m MEDTA solution at a soil/solution weight ratio of
1/25. Arsenic in the extract was determined by hydride generation inductively coupled plasma atomic emission
spectrometry. EDTA extractable arsenic showed significant positive correlation with Al-As, Fe-As, and arsenic
extracted by the methods of Mehlich I and III, Bray PI and Olsen
