Integral energy

Index Integral energy

Integral energy is the amount of energy required to remove water from an initial water content \theta_i to water content of \theta_f (where \theta_i > \theta_f). [1]

6 relations: Available water capacity, Nonlimiting water range, Soil, Water content, Water potential, Water retention curve.

Available water capacity

Available water capacity or available water content (AWC) is the range of available water that can be stored in soil and be available for growing crops.

Nonlimiting water range

The Non-limiting water range (NLWR) represents the range of water content in the soil where limitations to plant growth (such as water potential, air-filled porosity, or soil strength) are minimal.

Soil

Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life.

Water content

Water content or moisture content is the quantity of water contained in a material, such as soil (called soil moisture), rock, ceramics, crops, or wood.

Water potential

Water potential is the potential energy of water per unit volume relative to pure water in reference conditions.

Water retention curve

Water retention curve is the relationship between the water content, θ, and the soil water potential, ψ. This curve is characteristic for different types of soil, and is also called the soil moisture characteristic.
