Soil moisture is the key factor in determining how soils support vegetation and crops. Plants need water to survive and grow, and soil moisture determines the availability of water to plants. Different crops and plants have specific requirements for soil moisture, making it an important determinant of the suitable vegetation and crops for a region. The other options, such as sandy texture, iron content or depth of the B horizon, can affect soil properties, but they do not determine how soils support vegetation and crops.
