Micronutrients are bio-accumulated and bio-transferred both by natural and anthropogenic sources. Soil samples were collected in each season from selected sites (Rawatsar, Badopal and Loonkaransar) for four major seasons viz. spring, summer, rainy and winter from the saline tracks of division Bikaner. Samples were analysed for Copper (Cu), Iron (Fe), Manganese (Mn) and Zinc (Zn) by Atomic Absorption Spectrophotometer. Results showed that concentration of Copper was very high in all seasons, Manganese and Iron concentration was normal while Zinc concentration was low. It was noticed that the concentration of micronutrients were varied in the seasons.
