Study of carbon dioxide (co2) concentration distribution in the soil on mixed vegetation area land cover at specific sites of jonggrangan karst zone

Abstract

Karstification and soil physical factor in the soil at Jonggrangan Karst zone induces carbon dioxide (CO2) concentration dynamics. This research aimed to measuring soil CO2 concentration varieties on mixed vegetation area at specific sites of Jonggrangan Karst zone and analyze the relation among soil physical factors with CO2 concentration. The data were collected between the dry season and rainy season, as well as in different of soil depths at 20 cm, 40 cm, and 60 cm. The data was performed and explained graphically, comparatively, and built upon statistic descriptive. The result shows that the soil moisture has strong relation to CO2 concentration and shows a proportional trend vertically. The soil organic matter shows an inversely trend to CO2 concentration. The increase in CO2 concentration happens during the rainy season and is influenced by land cultivation.
