Abstract

Baseline data for trace elements of soils leaves and beans of cocoa need to be established before contamination of cocoa soils and plants by these elements through anthropogenic sources can be discussed. A study was conducted to determine total Cd Cu Ni and Zn concentration in selected cocoa soils from Perak Briah Gong Chenak Jawa and Serok series and in the leaves and beans of cocoa. The result showed that the soil concentrations of Cd Cu and Zn in the Briah and Jawa soils were significantly higher P less and equal than O.05 than in the Gong Chenak and Serok soils. The Jawa soil seemed to exhibit rather high concentration of Ni compared to the other soil series. Overall Cd Ni Cu and Zn were positively correlated with CEC P less and equal than O.05 while Ni Cu and Zn were positively correlated with organic C P less and equal than O.05. For the foliar the concentration of Ni in Jawa soil was significantly higher than that in all the other soil series. The Serok and Briah soils contained significantly higher Cu concentration in the foliar than that of the Gong Chenak and Jawa soils. The foliar zinc concentration of the Jawa was significantly higher than the Gong Chenak and Briah soils. There were no significant differences in the concentration of all these elements in the beans of cocoa grown on the Gong Chenak Jawa and Serok soils with the exception of Ni. The concentration of Ni in the beans of the Jawa soil was significantly higher than Gong Chenak and Serok soil. There were no correlations between the foliar concentration of each trace elements and the total concentration in the top 0-20 cm of the four soils.
