title: Study of cation-exchange capacity of soil near fluorspar mining with special reference to Kadipani mine (Gujarat, India).
abstract: One of the important functions of soil is exchange of cations, whereby essential trace metals are made available to plants as nutrients. Both minerals and organics fractions of soil exchange the cations. Clay minerals exchange cation because of the presence of negatively charged sites on the mineral while organic materials exchange cations by means of their carboxylate groups and other basic functional groups. Cation exchange in soil provides trace metal nutrients to plant. The metal ions are taken up by the roots while H+ is exchanged for the metal ions. Therefore, the measurement of Cation Exchange Capacity (CEC) of soil is important and this becomes more significant when the mining activity is carried out in the surrounding environment as mining activity may adversely impact the soil texture and organic matter content and sometimes changes the pH which is the main regulator of CEC in soil. The studies related to the assessment of CEC of soil were carried out. 14 soil samples, including one sample of mine site, were collected during summer season from different villages within 10 km radius from the mine site. These samples were then analyzed. The efforts were made to establish the CEC of soil quality of Kadipani, Distt. Vadodara, Gujarat, India. This study is useful for making the decisions regarding the environmental measures required for mining activity.
