phytoavailability

A specific instance of bioavailability with reference to plants. In some instances it is useful to differentiate between phytoavailability and bioavailability along the food chain.  Phytoavailability controls the transfer of a trace element from soil to a plant, and bioavailabilty controls the transfer of the trace element from the plant material to the receptor organism, the transfer factors are unlikely to be the same.
