Abstract

Soil nutrients are held within and on the soil aggregates and larger fragments made up of mineral and organic matter. They become available to plants by the progressive solubilization of mineral and organic soil constituents. The less soluble forms (constituents of minerals and adsorbed on soil colloids) release ions into the soil solution, thus ensuring supply to the plants. Direct uptake of elements by contact between roots and the solid soil phase accounts for less than 1 % of nutrients taken up from the soil by plants (Barber et al. 1963; Bosc and Maertens 1981).
