| description | A long-term field experiment on organic material application and crop rotation with green manure crops has been conducted since 1976 at Lopburi Agricultural Research and Development Center, Department of Agriculture, Lop Buri Province, Thailand, to clarify the effect of organic materials and green manure crop on soil organic carbon changes. The stock change factors that stand for the relative change of soil organic carbon on the carbon stock in a reference condition (native vegetation that is not degraded or improved). Stock change factor for input of organic matter (FI), representing different levels of C input to soil such as organic material application, crop residue treatment and green manure crop cultivation, was computed with the present field experimental results. While the computed FI of "High input with manure" was within the range of IPCC default FI value, some of the computed FI of " High input without manure" was much higher than the IPCC default though it was varied due to the biomass production and nutrient contents of the green manure crops planted as the second crops after corn. Therefore, the FI computed by field experimental results can contribute to more accurate estimation of SOC changes in farm land especially in Southeast Asia because the default FI mostly depends on the experimental data in temperate zones. Moreover, the field experiment has focused the effect of reduced tillage practices on SOC changes and corn yield since 2011. The results of the experiment will be used to compute Stock change factor for management regime (FMG) which represents the effects of tillage operations. |
