Abstract:
Mapping spatial variability of trace elements in rice field is necessary to obtain soil quality information to enhance rice production. This study was aimed to measure concentration and distribution of Zn, Cu, Fe, Pb, and Cd in two different sites (SP1, SP2) of Prafi rice field in Manokwari West Papua. The representative 26 soil samples were analysed for their available trace metal concentration (DTPA), soil pH, and C-organic and soil texture. The result indicated that Fe toxicity and Zn deficient problems were encountered in both sites. Rice field in SP2 was more deficient in Zn than SP1. Site with the highest trace elements (Zn, Fe, Cu, and Cd) concentration had low soil pH and high C-organic. Acidic soil has higher solubility of metals; while high C-organic could improve the formation of dissolve organic carbon-metal binding, hence it improving the trace metals concentration in soil solution.
