The study looked at how different types of soil (sandy and silty clay loam) behave when it comes to heat and moisture. They found that as moisture content increased, the soil's ability to conduct heat also increased, but only up to a certain point. After that, the heat conductivity stayed constant. The soil's ability to diffuse heat peaked at around 10% moisture content. The heat capacity of the soil increased steadily with moisture content. When the soil was compacted to a higher density, all these heat-related characteristics increased, regardless of the soil type.
