Abstract Adsorption of zinc in rice soils was studied to define the functional relationship between quantity, intensity and buffering capacity factors of soil zinc to the growth and zinc uptake of rice crop. A supply parameter integrating the quantity, intensity and buffering capacity factors into a single unifying term was computed from the data on Zn adsorption in these soils. A green house experiment was conducted with three soils providing a matrix of different values of supply parameter of Zn to determine the optimum value of this parameter for the proper growth and zinc nutrition of rice crop. Results indicated that a value of this parameter around unity is optimum for sustaining proper growth and zinc nutrition of rice in these soils. The variations in dry matter yield and zinc uptake of rice in different soils may be related to the differences in the physical and chemical properties of the soils.
