Metals in the form of salts or as such have a profound effect on development and growth of crops. Various soil samples at different regions of Dehradun (India) have been analysed analytically for the concentration of various metal ions in relation to the growth and development of wheat, mustard and barley. The various metal ions have been found in a good concentration range at which the concerned crops could show maximum growth and development. The concentration of various salts like phosphate ion as determined spectrophotometrically was found to be in between 0.732 to 1.610, for NO3- the concentration was found in between 0.210 to 0.998 mg/kg, and the concentration of NO22- was found to be 0.138 to 0.475 mg/kg. The metal ions were determined analytically and the concentration of various metals like Pb2+ was found in the range of 0.101 - 0.265 mg/kg, Zn in the range of 0.047 – 0.175 mg/kg, Cu in the range of 0.015 – 0.101 mg/kg and the concentration of Fe was found in the range of 0.120 – 0.462 mg/kg. Na, K, Li and Ba were analysed by flame-photometry and the concentration of Na was found in the range 0.10- 0.47 ppm, K in the range of 0.70 – 2.4 ppm, Li 0.00 – 0.01 ppm and the Ba in the range of 0.00 – 0.03 ppm. Also the data reveals the distributions of heavy metals in the agricultural land of the concerned region and can be used to estimate the risks associated with the consumption of crops grown on such soils. So the soil samples which have been examined can be opted for the production of various crops as the soil samples show a good quality and quantity of various mineral ions. The Dehradun in total bears a good range of forests and soil is rich of various types of mineral salts so could be used for the growth of multiple crops.
