At the end of the experiment, the sand in the vicinity of the soil moisture and thermal property sensors was destructively sampled and weighed to verify soil moisture conditions. In addition, the sand was oven dried and repacked into the cell to verify dry soil moisture and thermal property values.

Physical Properties of Soil. Soil Texture. The particles that make up soil are categorized into three groups by size – sand, silt, and clay. Sand particles are the largest and clay particles the smallest. Most soils are a combination of the three. The relative percentages of sand, silt, and clay are what give soil its texture.
