Coastal bermudagrass (Cynodon dactylon L.) may be a potentially important source of bio-based energy in the southern US due to its vast acreage. It is often produced as part of a waste management plan with varying nutrient composition and energy characteristics on fields irrigated with livestock wastewater. The objective of this study was to determine the effect of subsurface drip irrigation wi...

Subsurface drip irrigation (SDI) can substantially reduce the amount of irrigation water needed for corn production. However, corn yields need to be improved to offset the initial cost of drip installation. Air-injection is at least potentially applicable to the (SDI) system. However, the vertical stream of emitted air moving above the emitter outlet directly toward the surface creates a chimne...

Roots are the key elements in water saving rice cultivation. So, Background the response of rice roots are to be phenotyped under varied drip irrigation treatments. : This study describes an investigation on rice root Methods phenotyping under drip irrigation treatments in split-split plot design. Two lateral spacing levels (0.8 and 1.2m), laid at two depths of sub surface irrigation (5-10 and ...

Intensive agricultural activities in the Hetao irrigation district have severely degraded local aquatic ecosystems and water quality, and Ulansuhai Lake is now the most rapidly degrading eutrophic lake in China. A better understanding of the hydro-agronomic and pollutant transport processes in the area is thus urgently needed. This study simulated monthly streamflow, total nitrogen (TN) and tot...

Urban development can produce great impacts on local hydrology reducing infiltration and evapotranspiration, and increasing direct runoff volumes. Runoff control practices are implemented at local scales to control flow discharges and preserve the hydrological cycle. These techniques usually have green infrastructure therefore the application in semiarid and Mediterranean regions requires accou...

Pathogen Transmission Routes Research Program, describing pathogen pathways from farm animals to water bodies and measures that can reduce or prevent through the deposition of faeces by grazing animals directly into waterways in New Zealand. Bridging of streams intersected by farm raceways is an appropriate mitigation measure to prevent direct deposition during herd crossings, whilst fencing st...

demand for water resources in different parts of the world, necessitate the use of wastewater. in using wastewater the soil health must be considered. this study was carried out at green space zob ahan in the years 1382 to 1385. in this study, the effects of urban and industrial wastewater irrigation on some chemical properties of soil for three years by using five different irrigation treatmen...
