Students get a feel for soil-water relationships
Date:8/1/2010

e that number originated. Nor do they realize that this there isn't one value throughout the depth of the soil, but a continuum of water concentration that increases as you move from the top of the column towards the bottom.

A number of factors influence this soil water content continuum, including the soil texture, or the size of the soil particles, structure, or the way those particles are arranged, and depth to the water table.

The water retention relationship is a valuable tool in many disciplines. This is a relationship that connects the energy status of soil water to the soil water content. The soil water energy status, or potential, is the driver behind water movement in soils. Potential is also what plant roots must overcome to extract water from the soil. Plants wilt at very negative potentials, because they can no longer overcome the tension in very dry soils that limit water movement.

Through this very simple and inexpensive demonstration, students are better able to understand the soil, water, and plant relationships that surround us every day.
