Which of the following statements about soil water is true?
Answer Details
The statement that is true about soil water is: "crops utilize capillary water in the soil." Capillary water is the water held in the soil pores and is available to plants for use. The roots of plants absorb water from the soil through the process of osmosis. Capillary water is held in the soil by the surface tension of the water and the adhesion forces between water molecules and the soil particles. It is the most important source of water for plants, and its availability in the soil affects plant growth and crop yield. Therefore, farmers need to manage soil moisture levels to ensure that the plants have access to the required amount of capillary water.
