Abstract
Adequate supply of nutrients to plant roots is not merely a
function of total amount of a particular nutrient in the soil, but it
depends on the rate of replenishment of nutrient from the soil
solution also. Eventhough the nutrients are dissolved in soil solution,
the nutrients like Fe is not very mobile because of its entrapment in
the water filled fraction of the tortuous pore system of the soil. In
order to study the kinetics and uptake efficiency of Fe, many
mathematical models are being used to have a better understanding of
fundamental principles involved in the process of nutrient uptake by
plant roots growing in soil. These models are based on ion transport
from soil to roots by means of mass flow or diffusion as well as on
nutrient uptake kinetics, mostly following Michaelis-Menten kinetics.
Mechanistic models are useful tools for evaluating the significance of
