Freezing soil affects how water, heat, and salt move in the ground. Scientists did a lab experiment to see how soil temperature, moisture, and salinity change when soil freezes. They found that more water in the soil helps water move better. Colder freezing temperatures and denser soil slow down water movement. Water carries salt with it, and less salt moves in colder soil. The relationship between water, heat, and salt in the soil gets stronger with more moisture, but weaker with colder temperatures and denser soil. The study helps understand how water, heat, and salt move in cold areas, which can help improve soil quality and increase crop production.
