A GIS BASED SUSTAINABLE IRRIGATION MANAGEMENT PLAN FOR FERTI-IRRIGATION OF SUGARCANE WITH TREATED SPENT WASH (RESEARCH PAPER)

摘要

With the firstly growing Industries large volumes of distillery effluent have been discharged to various natural resources. Improper disposal of spent wash, in contamination with water, land and air causes health hazard of both human and animal beings. But there are certain recalcitrant compounds present in this spent wash which can causes good effect on plants. Therefore the scientific community has taken it as a challenge to treat this stream to make a proper utilization. The present study focus on the utilization of GIS technology for the ferti-irrigation of sugarcane treated with distillery effluent. To see the effect of the diluted (with water) distillery effluent sugarcane has been chosen as it shows good results. With the help of GIS we have prepared landuse map, pipeline zonation map and network accessibility map. As a result of this analysis we concluded with a sustainable irrigation management plan for sugarcane as well as recycling of distillery effluent in agro-ecosystem will not only eliminate the pollution of water reservoirs but check price inflation in the country and maintain soil health & water management. Nevertheless, the systematic information on long term impact of use of distillery effluent as pre-sowing or standing crop irrigation are not available. So far Last but not the least the Effluent's Nutrient may has a potential of saving Rs. 200 to 300 crore of national income in terms of liquid Fertilizer and will manage water budget.
