Subsurface (tile) drainage, while necessary for viable agricultural crop production in the humid, poorly drained regions of world, has been linked to offsite nutrient transport, culminating harmful algal blooms and hypoxia downstream waterbodies. Drainage water management (DWM), also known as controlled promoted a method reduce nitrogen (N) phosphorus (P) loss from field scale tile drainage; ho...
The effect of draining crop fields during the wheat season on the soil CH4 andN2O emissions during the rice season in this article. There were four treatments:traditional cultivation during the wheat season + cultivation without fertilizationduring the rice season (CK1 field), traditional cultivation during the wheat season +traditional cultivation during the rice season (CK2 field), draining t...
Holding up the phreatic surface near by the plant root zone to effective use of water and provide themoisture on the root zone is a usual method, which uses for several decades by researchers. In thisstudy, we investigate the possibility of controlled drainage method in dry and half-dryzone (i.e., theclimate of the center and south of the Khuzestan state) on thecane plant. The results showedtha...
Drainage Ditches Contribute Considerably to the CH4 Budget of a Drained and a Rewetted Temperate Fen
Small water bodies including drainage ditches can be hotspots for methane (CH4) emissions from peatlands. We assessed the CH4 of a drained and rewetted temperate fen managed unmanaged over course 2.5 years, covering three vegetation periods. Ditch in were significantly higher than fen. In contributed up to 91% annual budget, despite only 1.5% area. solely made ditch emissions. When uptake by pe...
BACKGROUND Peritonsillar abscess is a common infection presenting as a collection of pus in the peritonsillar area. The condition is characterised by a severe sore throat, difficulty in swallowing and pain on swallowing, fever and malaise, and trismus. Needle aspiration and incision and drainage are the two main treatment modalities currently used in the treatment of this condition. The effecti...
Hoor al-Azim wetland, are a large and permanent wetland area located between Iran and Iraq. By entering the flow to the wetland area, the geometry of the wetland, acts in the form of an inverted imperfect pyramid. So that by entering the water flow, the water level of wetland is simultaneous by increasing the surface. In this study by using the geometric relationships of pyramids, was acted t...
