Signs of a significant endogenous component in the thermal regime of soils on agricultural lands of the Novgorod region (based on digital satellite imagery)

Abstract

This study aims to identify a suitable test site for investigating the significance of the endogenous component of the soil energy budget in the natural conditions of the Novgorod region. Our previous research provided the basis for this study. We used metrologically supported digital remote sensing data from Terra / Aqua (MODIS), Terra (ASTER), and Landsat 8 satellites to select a test site based on signs of lands with additional endogenous heating from weak temperature thermal water or exothermic chemical reactions. Our analysis identified agricultural fields located in the coastal zone of Lake Ilmen, about 10 km from the Novgorod Research Agriculture Institute, as meeting all the criteria. Importantly, advanced snowmelt has been observed in these fields during the spring period. To confirm our hypothesis, a comprehensive experiment should be conducted to monitor all temperature-forming factors and control the cultivation of heat-loving crops. This research could contribute to a better understanding of the role of endogenous heating in soil energy budgets and its impact on agriculture.
