Soil suitability and water quality study in Tirupur areas using geographic information system techniques

, : Soil suitability and water quality study in Tirupur areas using geographic information system techniques. International Journal of Earth Sciences and Engineering 4.1

Agriculture plays a vital role In the economic development of India. The increase in agriculture production and related activities depends on the availability and quality of water sources and suitability of soil and hence to understand the relationship between the agricultural land use and soil conditions are important. In Tamil Nadu, Tirupur is known for its textile production which has direct influence of an economic development in the taluk and about 67% of land is being used for agriculture activities. In the present study, to assess the soil conditions and water quality, out of 39 villages about 12 villages have been selected for sampling sites. Water and soil quality are shown as GIS output in terms of pH, electrical conductivity (EC), chloride (Cl-), texture, nitrogen (N), phosphorus (PO4 ), potassium (K+) and other constituents. These parameters indicate that the levels of quality of water for drinking and irrigation purposes. Arcview 9.2 software was used for generation of various thematic maps and for spatial analysis and integration to produce the water quality and soil suitability map. The study revealed that the water sources in Tirupur taluk except Tirupur town, are suitable for both drinking and irrigation purposes. The Tirupur town and surrounding areas are not suitable for any agricultural activity because of high industrial pollution indicated in water sources.
