Abstract

Fertilizers in agriculture are potential sources of environmental pollution, especially in ground water quality and soil resources. Studying factors effective in water and nutrient transport through soil profile is helpful for nutrient management to minimize adverse impacts on environment and NITRATE leaching below the root zone. In this study, the GROUND WATER LEVEL and NITRATE leaching transportation below the root zone were measured in a paddy rice field and the data were simulated with the DRAINMOD-N model. For evaluating DRAINMOD-N software in a paddy rice field under surface drainage in Mazandaran, the GROUND WATER LEVEL and NITRATE transportation were measured during four months (June, July, August and September) in 2008. The DRAINMOD-N model was calibrated by adjusting NITRIFICATION and DENITRIFICATION rate constants to reach the best fit between measured and predicted data. Results indicate that predicted GROUND WATER LEVEL and NITRATE concentration by model were significant at one percent level. The statistical comparison was done by model efficiency (EF) 0.84 for estimation of GROUND WATER LEVEL and 0.97 for estimation of NITRATE concentration, respectively. The DRAINMOD-N model can be used as a tool to manage environmental pollution of NITRATE in PADDY RICE FIELDS.
