The property of a material that describes the quantity of matter in it; the ratio of the weight of a body and the acceleration due to gravity.
Industry:Earth science
The fraction of total P in fertilizer that is insoluble in water but soluble in neutral 0. 33 M ammonium citrate. Together with water-soluble phosphate, this represents the readily available P content of the fertilizer.
Industry:Earth science
The occurrence of the water level in a well rising above the top of the confined aquifer or, in special occasions, above the soil surface.
Industry:Earth science
Unattached pieces of rock 2 mm in diameter or larger that are strongly cemented or more resistant to rupture.
Industry:Earth science
The sum of an element in the soil solution and the amount of that element readily solubilized or exchanged when the soil is equilibrated with a salt solution.
Industry:Earth science
That portion of precipitation or irrigation on an area which does not infiltrate, but instead is discharged from the area. That which is lost without entering the soil is called surface runoff. That which enters the soil before reaching a stream channel is called ground water runoff or seepage flow from ground water. (In soil science runoff usually refers to the water lost by surface flow; in geology and hydraulics runoff usually includes both surface and subsurface flow. )
Industry:Earth science
The science that studies the evolution of the earth's surface. The science of landforms. The systematic examination of landforms and their interpretation as records of geologic history.
Industry:Earth science
The activity of hydrogen ion in the aqueous phase of a soil expressed as a pH value.
