The soil samples collected after 31 cropping cycles (2017) from ongoing long-term fertilizer experiment under the finger millet-maize cropping system at GKVK, Bengaluru were studied for different fractions of calcium (Ca) and magnesium (Mg) and available nutrient status. The different fractions of Ca and Mg were in the order of mineral>acid soluble> exchangeable>organic complexed form. All forms of Ca and Mg were significantly higher in the treatments receiving 100 % NPK + FYM + lime (T10). All fractions of Ca and Mg content were lower in the treatments receiving imbalanced nutrients. The correlation study revealed that pH, EC, OC, and nitrogen content are important parameters in influencing the status of Ca and Mg fractions. There was a positive correlation between grain yields (finger millet and maize) and fractions of Ca and Mg.
