| Summary: | Distribution of long-term in agricultural land use on soil organic C (SOC) is important to farmers and policy makers. The overall goal of this research is to quantify the distribution of soil carbon status in paddy field and secondary forest as comparison, the specific objectives of this study to investigate the status of selected soil chemical properties in paddy field. Status of soil nutrients and fertility was studied in two are which in paddy field of sawah sagil, Batu Phat, Johor and secondary forest at University Putra Malaysia Campus Bintulu Sarawak. Soil samples were taken in a plot of 20 × 20 m² at 0 – 20 cm depth. The soil fertility indicators such as Carbon (C), Nitrogen (N) and Sulfur (S) were using TruSpec Micro CHN analyzer. And Phosphorus (P), Potassium (K), pH and soil texture using standard procedures. The soil of paddy field was found to be most fertile compare to secondary forest. The result showed total C were 4.505 ± 0.026 % in paddy field compared to in secondary forest the total C were 1.6868 ± 0.0815 % in the entire 0 – 20 cm depth. The pH, total N, P, K, S shown that have significant different between paddy field and secondary forest. The analyses of SAS with T- test showed significant (P< 0.05) difference among the two are types with regard to the soil nutrients studied. These results showed that land use types have significant effect on soil nutrients studied. These results showed that land use types have significant effect on soil nutrients and thus its fertility. Thus we can conclude that, evaluate the changes in soil organic carbon status and physic-chemical properties in paddy field depending agricultural practices have potential to sequestered amount of carbon in paddy field. |
