A simulation model was developed to estimate the effect of deficit irrigation upon crop yield. The model was designed to provide relative yield estimates for numerous combinations of irrigation system, crop growth and irrigation management parameters. A daily soil moisture balance was used to predict evaporation and transpiration from which crop yields were estimated. Gross irrigation water req...

[email protected] Abstract – Previous studies have shown that irrigation can impact the near-surface climate, but none refer to the differences in the impacts of irrigation types such as flooding and spraying. In this study, we add a novel irrigation module to the recently released community land model 4.0 and simulate irrigation in two ways: first, by spraying water...

Introduction. This experimental study is to compare radiographs based on the penetration depth of the irrigant following three final irrigation techniques. Material and Method. A sample of sixty teeth with single roots were prepared with stainless steel K files followed by mechanized Ni-Ti files iRace® under irrigation with 2.5% sodium hypochlorite. Radiopaque solution was utilized to measure t...

A comparison of decision rules has been made for case studies of corn production using subsurface drip irrigation under three agricultural management practices (no irrigation, uniform irrigation, and variable rate irrigation). The uniform irrigation strategy appeared to perform the best than the other two management practices under different risk scenarios.

OBJECTIVE To compare intranasal distribution of saline solution delivered by three popular methods for nasal saline irrigation. STUDY DESIGN Prospective, controlled comparison. METHODS Eight healthy adult volunteers received nasal irrigation with 40 mL of isotonic, nonionic contrast material immediately before having coronal computed tomography to visualize distribution of solution in the p...

Abstract In most developing countries non-irrigation status often dominates adoption of traditional and modern irrigation technology. In this paper, we study the effect of production risk on irrigation technology choice among small-scale farmers in Chile, applying sample selection and discrete choice models. We find that more educated farmers, with credit access, receiving extension services, a...

Between 10 May and 20 June 2005, Sydney West Centre for Population Health (SWCPH) was notified of 29 cases of cryptosporidiosis. SWCPH staff interviewed these cases about their potential sources of exposure to infection and found that 11 (38 per cent) swam at the same indoor heated public pool. The onset of illness in these 11 cases ranged from late April to early June. Nine of these cases were...

Irrigation management is based upon delivery of water to a crop in the correct amount and time, and the crop’s water need is determined by calculating evapotranspiration (ET) using weather data. In 1994, an ET-network was established in the Texas High Plains to manage irrigation on a regional scale. Though producers used the ET-network, by 2010 public access was discontinued. Why did producers ...

Saline irrigation has been shown to be both experimentally and clinically efficacious in decreasing bacterial contamination as well as decreasing infection rates. The dynamics of irrigation delivery fall into two primary categories: simultaneous and intermittent irrigation. An important component to irrigation therapy is distribution of irrigation solution to hard-to-reach areas of a wound bed,...
