Abstract

Nutrient acquisition by roots from soil is a complex process which is dependent on several root features: (1) morphological root characteristics, including mycorrhizal associations, which determine the extent of the interface between plant and soil (2) ability to modify the nutrient availability in the rhizosphere, and (3) ability for nutrient uptake through the plasma membranes (for reviews see Barber 1984; Clarkson 1985; Marschner 1995). The relative importance of these factors for nutrient acquisition is dependent on environmental conditions and the specific nutrient, particularly its chemical availability and mobility in the soil.
