Abstract
Investigations of pH and heavy metals contents of Pb, Cd, Ni, Cu, and Zn in cocoa plantations soil of East Kolaka has been conducted by using pH starter Ohaus 3000 and Atomic Absorption Spectroscopy (AAS) Shimadzu AA6300. Based on the investigation, it is known that acidic soil plantation with pH ranges between 4.45 to 6.26, and also contains Pb, Cd, Ni, Cu, and Zn with an average concentration (mg/kg) are 1.45, 0.02, 0.85, 0.77, and 1.49, respectively. The existence of Pb and Cd in plantation soil have been exceeded the WHO permissible, whereas Ni, Cu, and Zn is still within the permissible limits. Acidic soil plantation will give opportunity metal ions such as Pb ,Cd2+, Ni2+, Cu2+, Zn2+, and Al absorbed by plants. Thus causing the accumulation in plant tissues and make the cocoa plants stress of heavy metals.3+2+
