Abstract
Phosphorus is a basic nutrient for plant growth. P uptake by white clover is the result of a passive and an active process: the firts a mass flow effect and the second called as a “proton motor force” mechanism. The passive process, is dependent from the external nutrient concentration, permeability of root tissues and plant transpiration rate.
