Abstract
Abstract: The study assesses Carbon dioxide emissions from agricultural land use which have a great impact on food production and atmospheric weather. Emissions of CO2 from the land use surface lead to minimum production of farm products. Global warming and climate change are the cause of great concern, demanding intensive research on CO2 emissions from soil under some management options. The aim is to determine CO2 emission on agricultural land use with food security. An experiment was conducted using sodium hydroxide as a reagent for the emission, the results obtained demonstrated that the highest CO2 emission was observed in maize farm which is 6.0 g CO2 m-2 d-1 and the least was found in yam farm and forest location which are 0.5g CO2 m-2 d-1, at a point where the soil moisture was maximum (23.5%), the soil pH was minimum (4.84), the total organic carbon (TOC) storage in the soil was maximum (1.7%), then the CO2 emission was low in a forest location because mineralization of soil bacteria’s is not active in moist soil they are very active in a soil that lacks moisture, and bacteria contribute to the emission of carbon dioxide due to their activities in the soil.
