Moisture Retention Curve

A Moisture Retention Curve shows the relationship between soil moisture content and the soil’s ability to hold that moisture at different levels of dryness or wetness. It illustrates how much water soil can retain when it’s wet, and how easily it releases water as it dries. This curve is important for understanding water availability for plants and soil health. Typically, it’s represented as a graph with moisture content on the y-axis and a measure of soil tension or dryness on the x-axis, helping to predict how soil will behave under different moisture conditions.
