The overelevation of the water table in surface irrigation plots is one main factors affecting salinization agricultural soils. Therefore, it necessary to develop simulation models that consider effect a shallow process advance-infiltration an event. This paper, first series three, develops simple mathematical model for advance phase border soils with presence table. In this study, hydrodynamic...

Irrigation underpins agricultural productivity. The purpose of irrigation is to match water supply to crop water demand. The effectiveness of irrigation depends on the quality of the timing and duration of watering events, also called irrigation scheduling. Most farmers use heuristic rules to determine irrigation events. This often leads to over-watering which results in lower crop yields and w...

OBJECTIVE To compare the ability to eliminate debris and open dentinal tubules of different ultrasound irrigation procedures. STUDY DESIGN Forty extracted single-rooted human teeth were instrumented with mechanical rotatory instrumentation, and divided into four groups: (n=10) according to the final irrigation technique: group A (control), 2.5% NaOCl irrigation with the Miraject needle and no...

INTRODUCTION The purpose of this study was to compare the debridement efficacy of EndoVac irrigation versus conventional needle irrigation in vivo. METHODS Seven adult patients with a total of 22 matched pairs of single-canaled vital teeth with fully formed apices were recruited. Canals were instrumented to a master apical file size #40/.04 taper. One tooth from each matched pair was irrigate...

In the past ten years, smart irrigation controllers have been developed by a number of manufacturers and have been promoted by water purveyors in an attempt to reduce excessive irrigation. Legislation has been introduced in California and Texas and passed in Florida mandating or incentivizing the use of these controllers. As a result of the interest in smart controllers, their use is increasing...

Timely irrigation of cotton has been shown to increase yields, but almost every year producers and researchers observe poor plant development even with irrigation under some condition. Adequate moisture must be present when the cotton crop needs it, but saturated soil conditions deprive the roots of necessary oxygen. Current recommendations lack detail concerning irrigation management. Use of t...

Irrigation is probably the most underrated procedure in Endodontic therapy. While most articles or presentations spend a great deal of time on shaping procedures, not much emphasis is given for irrigation. This has led to a great deal of confusion on the type of irrigant, the protocol and the method of use. The purpose of this article is to discuss root canal irrigants, irrigation techniques an...

In this paper, we present the results of our study on the operational application of the reflectance-based crop coefficient for assessing table grape irrigation requirements. The methodology was applied to provide irrigation advice and to assess the irrigation performance. The net irrigation water requirements (NIWR) simulated using the reflectance-based basal crop coefficient were provided to ...
