Quizplus · Accepted Answer

The wilting point is the point at which plants cannot extract enough water from the soil to sustain growth. Clay particles are smaller and more numerous than sand and silt particles, and water is very tightly bound to them, making it harder for plants to extract water from clay soils. Therefore, the amount of water associated with the wilting point in clay is greater than that for sand and silt.
