Soils
The achieving of 17 United Nations Sustainable Development Goals (SDGs) is closely linked to sustainable soil management to provide food, fibre, fuel, to avoid land degradation, to promote land restoration, water regulation, nutrient cycling and to ensure habitat for biodiversity. Organic soils can be a carbon sink or a carbon source depending on land use and land use management. Agricultural production on organic soils is considered as an important source of anthropogenic CO2 and N2O emissions.
Long-term plans to mitigate the GHG emissions and to ensure socio-economic interests are needed to reduce the negative impact on environment caused by management of organic soils for agricultural purpose. Therefore, there is a necessary to evaluate the effect of different agricultural practices and environmental factors on GHG emissions from organic soils in order to estimate the whether a changes in management would reduce the negative impact.
This study investigated the dynamics of N2O, CH4 and CO2 emissions from organic soils in two measurement sites in vegetation period from 2017 to 2020 and the effect of environmental factors (soil temperature, precipitation, air temperature) on formation of N2O, CH4 and CO2 emissions. The dynamics of N2O, CH4 and CO2 emissions from organic soils are significantly affected by the site (p<0.001, p<0.01, p<0.05). Kendall correlation coefficients show that soil temperature is the main factor which influence the N2O, CH4 and CO2 emissions, while precipitation affects the formation of N2O emission from organic soils.
