Soil Moisture Retention Curve
The Soil Moisture Retention Curve is a graph that shows how tightly soil holds onto water at different moisture levels. It illustrates the relationship between the percentage of water in the soil and how easily or difficult it is for plants to extract that water. When the soil is wet, water is held loosely and plants can easily access it. As the soil dries, the remaining water is held more tightly and becomes harder for plants to use. This curve helps understand soil water availability and is important for agriculture, gardening, and water management.
