32 degrees F 0 degrees C Soil is already in a solid state and therefore cannot freeze... it is already frozen. What freezes is the moisture in soil. The freezing point of water is 32 degrees F.
To effectively use mulch in raised beds, spread a layer of organic mulch like straw or wood chips on top of the soil. This will help improve soil quality by adding nutrients as it breaks down. The mulch also helps retain moisture by reducing evaporation, keeping the soil moist for your plants. Be sure to replenish the mulch as needed to maintain its benefits.

To determine the moisture content of soil, you can use a soil moisture meter or follow the oven-drying method. With a soil moisture meter, insert the probe into the soil and read the moisture level displayed. For the oven-drying method, weigh a soil sample, dry it in an oven, and weigh it again to calculate the moisture content.
ofcourse.humidity add moisture in the soil......
Freezing/Thawing - Water in the soil freezing creates ice crystals that push the soil particles outwards, causing what is called "heave." When the ice crystals thaw, the soil flows don the slope due to gravity. Wetting/Drying - Heavy rainfall causes an increase to the moisture in the soil, which increases the volume and weight of the soil. This allows the soil to move down the slope under the influence of gravity. When the soil, especially clay, dries out, the soil contracts.
The soil in a region is saturated, and rainfall is greater than the need for the moisture.
A test for soil moisture is to:1. weigh a brown paper bag2. add a sample of your soil to that bag3. weigh the total weight of the bag plus the soil4. put the bag of soil in an oven for 24 hours at 200 degrees5. reweigh the bagsubtract the final/dry weight of the bag from the initial soil bag weight and that number will be the weight of moisture that has left the soil.
Soil moisture meters are devices to measure the soil moisture for irrigation messuring. Some devices have data logging or georeferencing capabilities.Some of the other functions of soil moisture meter:Monitoring the soil moistureMonitor salinity and temperatureTo check the electrical conductivityTrack and manage salinity levels
Evaporation process in the hydrologic cycle puts soil moisture in the atmosphere. The moisture is evaporated.
