Solution (By Examveda Team)

The inorganic and organic labile P fractions of soil are collectively called the Quantity factor.
Quantity intensity is a fundamental relationship that determines ion uptake about the status of ions present in the soil solution.
Labile phosphorus is more plentiful than soluble P but is still only a small fraction of total soil P. This soil P fraction typically accounts for less than 1% to less than 5% of the P in soils and is more tightly bonded than stable P.
