Analysis of fertilizer application on soil heavy metal concentration in coffee plantation / Nur Hanini Hamzah

Agricultural activities use a large amount of chemicals such as fertilizer and
pesticides. The application of fertilizer may result in the increase of Cd, Cr, Cu,
Zn and Pb. The objective of this study was to investigate the variability
concentration of these heavy metals pollution in soil increases due to application
of fertilizer. Then, this study also was done to analyze the impact of heavy metal
concentration from chemical fertilizer using geochemical approaches and
contamination factor. Samples of soil were collected from coffee plantation
located at Pusat Penyelidikan Pertanian Tun Abdul Razak, (PPPTR) Jengka. The
result from analysis using ICP-OES indicated that Cd, Cr, Cu, Zn and Pb
concentrations in soil were slightly differences and increased due to fertilizer
application. The level determined by geo-accumulation index is uncontaminated.
While contamination factor parameter indicate all classes of heavy metals
involved.
