ABSTRACT
Soil carbon or more accurately referred to as soil organic carbon (SOC), because most of the soil carbon is in the form of organic matter, is very important as the main indicator of soil fertility or productivity and sustainability of terrestrial ecosystems but is also an important component in the global c cycle. Its existence will have an impact on the global climate in the future. As a c storehouse with the largest capacity to store and release organic c on land, soil interacts strongly with changes in atmospheric composition, climate, and land cover. Changes in the amount of soc on land can have a significant global effect and can reduce or increase climate change. Therefore, it is necessary to study the correlation between vegetation biomass and soil carbon in various types of dry land use in aceh besar district. Study this implemented on one unity land in the area dry in regency aceh big with wide area studies 239,439.63 ha. The laboratory of soil and plant sciences and the laboratory of physics faculty land university agriculture Shia Kuala conducted analyses of soil samples and biomass samples. Writing instruments, other supporting tools, and a set of PCs running Microsoft Windows 10 with analysis software was among the tools used in this study. Soil samples, tree diameter measurement data, and land use maps containing information on topography, geology, climate, slope class, and soil were the primary resources used in this study. A value of 0.6076 was revealed by the correlation analysis test results. This shows that the relationship between vegetation biomass and soil c potential at a soil depth of 30 cm is a strong correlation. The relationship between soil carbon and carbon biomass in various types of dry land use is very close. The more plant stands and the diameter of the stem, the more carbon biomass will increase in a type of land use.
