Sažetak
Soil electrical conductivity (EC) is an important indicator of soil health. It affects crop yields and suitability, many soil properties like plant nutrient availability, and activity of soil microorganisms which influence key soil processes including the emission of greenhouse gases such as carbon dioxide i.e. soil respiration. While it is well known that major drivers of soil EC are soil temperature and moisture content, less is known on the relation between soil EC and respiration. Therefore, the objectives of this research were to determine relation of soil EC and soil microclimate (soil temperature and moisture), as well relation of soil EC and soil respiration under three different land covers. A study on soil EC, microclimate and respiration under bare soil, winter wheat and winter barley was carried out from November 2020 until July 2021 on experimental field near Osijek city, continental Croatia. The results showed that EC is more related to soil microclimate elements i.e. soil temperature and soil moisture content than on soil respiration. Between 17% and 47% of EC can be explained by soil microclimate elements and none i.e. only 4% to 12% by soil respiration.
