The isotopic composition of N and O nitrate (NO3?) is usually employed to trace its sources pollution in groundwater. In agricultural areas, the amount NO3? that reaches aquifers after fertilization controlled by different transformation processes can affect nitrogen species composition. Aiming address reliability using isotope tools groundwater NO3?, goal this study was check effect on compoun...

The research in the fields of irrigation and drainage network in the province Hamidieh to evaluate the performance of drainage was done in the land. For this purpose, three drainage server farm at intervals of 50, 70 and 80 meters in the area was selected. Blank observation on three drain pipes at intervals of 0.3,0.8,1.5,2.5 and 15 meters of lateral drains in the middle of the line in four row...
