simulation of nitrate transport in mazandaran paddy field during canola cultivation season for water resources management
in this research, the appropriateness of drainmod-n model was evaluated for the simulation of nitrate transport with subsurface drainage in paddy fields. during a canola growing season from november 2011 to april 2012, the nitrate concentration of drainage water and soil saturation extracts of two depths of 30 and 60 cm was measured in consolidated paddy fields of sari agricultural sciences and...
متن کاملPredicting ground water nitrate concentration from land use.
Ground water nitrate concentrations on Nantucket Island, Massachusetts, were analyzed to assess the effects of land use on ground water quality. Exploratory data analysis was applied to historic ground water nitrate concentrations to determine spatial and temporal trends. Maximum likelihood Tobit and logistic regression analyses of explanatory variables that characterize land use within a 1000-...

Research on the populations of rice grain bug Paraeuscosmetus pallicomis Dallas (Hemiptera: Lygaeidae) in paddy field ecosystems was performed with the aim to determine the populations of rice grain bug in weed-free paddy field, weedy paddy field, and paddy dykes. Experiment was carried out in the village of Paccellekang in the district of Patallasang of Gowa Regency in South Sulawesi, Indonesi...
متن کاملواسنجی آب‌شویی نیترات و نوسانات سطح ایستابی در زمین‌های شالیزاری با استفاده از نرم‌افزار DRAINMOD-N
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 transp...
متن کاملMeasurement of Vertical Water Percolation Through Different Soil Textures of Paddy Field During Rice Growth Season
The water percolation loss beyond root zone in the soil is one of the important parameters to determine water requirement of rice plant. If the amount of water percolation rate into the soil is estimated more carefully, determination of water requirement will be evaluated better and designing for system of irrigation, drainage and related establishments will be more easily done. The purpose of ...
