Synergistic and Antagonistic Interactions of Calcium with Other Nutrients in Soil and Plants

Interaction between nutrients in crop plants occurs when the supply of one nutrient affects the absorption and utilization of other nutrients. Nutrient interactions may be positive (synergistic) or negative (antagonistic) and also possible to have no interactions. Interaction of calcium with other macro and micro nutrient hinders the nutrient availability to crop plants by forming different complexes and precipitates. Calcium is divalent ion which competes for the adsorption site of the soil and other labile pool nutrient gets affected. Increase in soil pH due to calcium carbonate content in soil which also restricts the micro nutrient availability.
