Measurement of soil CO2 emissions in Croatia

The agricultural sector is a source of greenhouse gas emissions that directly affect the global problem of climate change. Soil-plant-atmosphere interactions i.e. the boundary between the pedosphere and atmosphere is site of carbon exchanges. The studies have shown that factors such as agrotechnical measures, agroclimatic factors, vegetation, soil properties and many others, have influence on soil CO2 emissions. Irregular and irresponsible agricultural practices, such as excessive tillage and improper fertilization often leads to soil carbon loss and increased CO2 emissions to the atmosphere. The reduction of CO2 emissions by soil carbon sequestration is of primary importance as agricultural and forestry practices can remove atmospheric carbon by sequestration and thus mitigate the climate change by maintaining and/or increasing the amount of carbon stored in the soil and plant material. Due to the lack of research and national data related to the soil respiration, a 3-year research, with the aim to determine the C-CO2 emissions (fluxes) in natural agro-climatic conditions, was conducted under the project " Influence of Different Land Management on Climate Change " (leader: Željka Zgorelec, Ph.D.).
