    Major cationic and anionic composition of ground water of Crop Research Centre, Pantnagar, with special reference to irrigation
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2007-06) Kumar Amit; Viveka Nand
    The study area i.e CRC (Crop Research Center), G. B. Pant University of Agriculture and Technology, Pantnagar is extended to an area of 230 ha. It is located at the foot hills of Shivalik range of mountains in Kumaon at 29°N latitude and 79°3’E longitude at an altitude of 243.84m above mean sea level. It provides facilities for research on various field crops. Scientists and post graduate students from various disciplines conduct field experiments on rice, wheat, maize, soybean, grain legumes, oilseeds and sugarcane. Entire area is irrigated with artesian wells and tube wells. The samples were collected from an artesian well, located at the distance of about 2.5 to 3 meters right side from the main entrance of the Crop Research Center, Pantnagar. In view of the existing literature, the proposed plan of work broadly concerns to conduct a study of hydro chemical properties of ground water sources of crop research center, Pantnagar with the following objectives viz to study the major inorganic cationic and anionic composition, to evaluate suitability of ground water for livestock,to utilize hydro chemical properties to assess irrigation qualities like magnesium content, sodium percentage (Na %), sodium absorption ratio (SAR), residual sodium carbonate (RSC) and permeability index (PI). Hydrochemistry of the ground water in the study area shows that, the alkaline earths (Ca2+ and Mg2+ ) exceed the alkalies (Na+ and K+), weak acid (HCO3 -) exceeds strong acids (Cl-, SO4 2-, NO3 -), that is total hydrochemistry is dominated by alkaline earth and weak acid. Hence the ground water of the stydy area is calcium magnesium bicarbonate type. The total concentration of the major ions in the ground water increases at the end of monsoon ie. at the post monsoon periods, in comparison to those at the end of lean period. The groundwater is highly suitable for drinking purpose and public health because hardness of the ground water is below the permissible limit of 500 mg/l. The groundwater is also suitable for irrigation with low alkali hazard. The SAR, RSC, Na%, PI, magnesium content were within the safe water limit recommended for irrigation purpose.
