Explanation:
Detailed explanation-1: -Water is important for transporting nutrients to growing plants and soil organisms and for facilitating both biological and chemical decomposition.
Detailed explanation-2: -Rainfall dissolves some of the soil materials and holds others in suspension. The water carries or leaches these materials down through the soil. Over time this process can change the soil, making it less fertile.
Detailed explanation-3: -Water held tightly by soil particles around them is called hygroscopic water. It is held in a very thin film and is not available to plants. Plants are able to absorb capillary water which is present in the capillary spaces between soil particles. Run away water is also not available to plants.
