Abstract
A pot experiment was conducted with ragi (Eleusine coracana Gaertn.) and tomato as test crops in a red calcareous loamy soil. The fertiliser treatments consisted of four levels of nitrogen and three levels of potassium. Plant samples were collected at vegetative, reproductive and post-harvest stages of crops and were analysed for nutrient elements like nitrogen, phosphorus, potassium, calcium and magnesium. Correlations between root CEC of the plants and the ratios of cation uptake of the two crops indicated the dislocation of valence effect and Donnan equilibrium. However CEC was best correlated with the total cation uptake. Application of both nitrogen and potassium varied the content of individual cations but not the total and the total cation content was constant for each crop
