Soil science
Nutrient-supplying power of soils
Earth science; Soil science
The capacity of the soil to supply nutrients to growing plants from the labile, exchangeable, and the moderately available forms.
Flux concentration
Earth science; Soil science
The mass of solute per unit volume of fluid passing a unit area of soil during a unit time period, equivalent to the ratio of the solute flux to the water flux.
Storativity
Earth science; Soil science
The storage term for a confined aquifer. Defined as the volume of water released from a confined aquifer per unit surface area of the aquifer and per unit drop in the hydraulic head.
Total potential
Earth science; Soil science
The sum of the separate energy components acting upon soil water expressed as energy per weight (head) or energy per volume (potential).
Hortonian flow
Earth science; Soil science
Surface runoff as a result of rainfall in excess of the soils infiltration capacity.
Land evaluation
Earth science; Soil science
The process of assessment of land performance when the land is used for specific purposes.
Resident concentration
Earth science; Soil science
