Heat Exchange in Soil

  • This diagram shows how heat is exchanged with the soil in warm and cold seasons.
  • When sunlight shines directly on the soil, the top layers will be warmer and heat will conduct downward into the deeper layers.
  • When sunlight shines at an angle, heat from the warmer lower layers will conduct back up to the surface.
  • Seasonal crops depend on particular soil temperatures for maximum growth and productivity.
