Abstract

This study investigated the effects of soil compaction and exposure of the soil surface to rainfall and their interaction on CO2 release. Therefore, the AA. conducted a factorial laboratory experiment with 3 soil types after sieving (clay, silt and sand soil), 3 different bulk densities and 3 different exposures to rainfall. The results demonstrated CO2 release varied significantly with bulk density, exposure to rain and time. The relationship between rain exposure and CO2 is positive. Bulk density exhibited a negative relationship with CO2 emission. Furthermore the AA. found that the magnitude of CO2 effluxes depended on the interaction of these 2 abiotic factors. Given these results, understanding the influence of soil compaction and raindrop impact on CO2 emission could lead to modified soil management practices which promote carbon sequestration
