Effects of heat waves on soil temperatures in Slovenia

Soil temperature regulates the rate of plant growth and tells us much about climatic characteristics a particular site. Climate variability extremes need to be studied there is large gap in knowledge soil during heat waves. Agricultural land highly dependent on waves, which are becoming longer, more intense frequent, it important monitor temperatures situ understand their changes Therefore, aim this work was investigate how change at different depths after Average daily air data for 25-year period 1992-2016 were evaluated four agrometeorological stations three climate zones Slovenia analyzed waves determined according Slovenian definition. During 1992-2016, 53 (Lesce) 76 (Ljubljana) identified. Analysis average before, showed higher responsiveness upper part soils an increase time lag between maximum with depth. The wave reached nine days, depending Only Moderate hilly region, depth 100 cm remained below 20°C wave. rise deeper layers lasts longer than shallower layers.
