When the soil freezes during winter, it releases heat to the atmosphere because water releases heat when it changes from liquid to solid ice. This is known as latent heat release. Soil can also store heat from the sun. Frozen soil releases more of this heat than soil that is not frozen because frozen soils conduct heat better.

Jan 5, 2018 · “Dry soils cool more rapidly because of lack of water, which has a high heat content. With the consistent extreme cold and cold temperatures likely continuing in January, frost depths will continue to penetrate deeper.” The National Weather Service has a map of frost depths.

Before we look into the ways of increasing soil temperature, it is important to first understand the factors affecting it.
2.1 Cover with plastic or mulch
Cover the soil and the irrigation lines with a piece of plastic or organic mulch like straw or bark chips can help increase soil temperature. The plastic and mulch act like vegetation covering, keeping heat from escaping the soil and preventing cold rain and late snow from getting to the soil. The most common type of plastic mulching is black plastic. It can also be “rows of covers” which is a light, semi-transparent and porous fabric that allows sunlight and water to pass through it while ke...
2.2 Build a cold frame or low tunnel
Low tunnels and cold frames are insulatingstructures. Like plastic mulching, they protect the soil from cold rains, cold breezes, and snow. At the same time, they prevent heat from escaping, thus creating a mini-greenhouse over the crops. Low tunnelsare typically 4 feet tall and 3 – 4 feet wide. They can be easily constructed by staking a series of metal or PVC hoops in the ground and covered with a waterproof membrane. They’re suited for ridges because of their long and tunnel-like structure...
2.3 Use Wall O’ Water
A Wall o’ Water or season extender is a tubular structure made of thick plastic sectioned into smaller cells filled with water. The water absorbs the heat from the sun during the day and releasesit to the seedlings at night. You place it over the plants and fill the individual cells with water. This allows it to stand upright and creates a barrier around the plant, shielding it from the cold and preventing heat from escaping. The water will also absorb some heat in the daytime and release it...
The most effective way to increase soil temperature is by covering it with plastic mulch when the air temperature falls below 45 Fahrenheit (7 Celcius). This method is cost-effective and easy to install. A “wall of water” is equally inexpensive, easy to install, and lasts for long. You can use it in combination with the plastic mulch. The plastic c...
Apr 24, 2024 · Soil forms most readily under temperate to tropical conditions (not cold) and where precipitation amounts are moderate (not dry, but not too wet). Chemical weathering reactions (especially the formation of clay minerals) and biochemical reactions proceed fastest under warm conditions, and plant growth is enhanced in warm climates.
Jan 12, 2018 · The actual effects of a freeze depend on how compacted your soil is, and even the type of clay. A clay thank can shrink and swell will also reduced compaction with wet/dry cycles, even without the effects of a freeze.

Mar 10, 2023 · You can expect clay soil to dry in 3-5 days, pending the location. Clay takes long to dry when compared to other soils and needs to be watered less frequently. Keep reading as we discuss signs that show your clay soil is dry and explain what happens when this soil gets wet.
