Abstract:

The heat flow and the amount of heat in the land horizons are one of the main thermo-physical parameters that significantly affect the pedogenic processes of the various land armies, the potential energy change accumulated in the land, the formation of the energy balance, along with other factors. The purpose of this study is to determine the heat flow and the amount of heat according to the temperature values measured in the profiles of young (Entisol) and developing (Inceptisol) soils formed under semi-humid ecological conditions and on aluvia deposits. Inceptisol is determined that when compared with Entisol soil depending on the genetic horizon development of the soil, the heat flow and the amount of heat is higher. In the Vertic Haplustept and Typic Haplustept land profiles of the Inceptisol army, the heat flow and heat amount varies between 13.221-50.035 watt m-2 and 2.285∙106-8.646∙106 J m-2; 7.757-29.284 watt m-2 and 1.340∙106-5.060∙106 J m-2 respectively. In the territory of the Entisol army (Typic Ustifluvent, Mollic Ustifluvent-1, Mollic Ustifluvent-2) the heat flow was found to change in the range of 8.958-34.300 watt m-2, the heat amount of 1.548∙106-5.927∙106 J m-2. Also, due to the increase in depth in the soil of both ords, the heat flow and the amount of heat has decreased. It is believed that this change has come from the fact that the variations in the amount of organic substances and the volume weight of the soil have a significant impact on the heat flow and the amount of heat. Furthermore, the change of the temperature difference in any time interval; the interaction between the volume heat capacity, the heat transmission and the heat conductivity significantly affects the heat flow and the amount of heat in the horizons.
