Fertigation is herein defined as the application of solid or liquid (fluid) mineral fertilizers via pressurized irrigation systems, thus forming nutrient containing irrigation water. Although the practice of fertigation only started commercially in the mid 20th century, there is evidence that the concept of irrigation with dissolved nutrients was well known in the past. The first reported examp...
The assessment of actual performance and potential improvement of conveyance and distribution systems received greater attention in recent years, and this trend will most likely extend to the near future, given that public and private investments will be more addressed to modernization of ageing or poor-performing irrigation schemes rather than to development of new irrigated areas or to expans...
Pressurized irrigation systems have gained more attention lately, among other alternatives, in Mediterranean countries. Since the initial investment costs of pressurized are quite high, it is crucial to determine design parameters such as pipe diameter. Most current optimization techniques for diameter selection based on linear, non-linear, and dynamic programming models. The ultimate aim these...
BACKGROUND AND PURPOSE The Peditrol is a novel hands-free irrigation device that delivers a bolus of irrigant through the ureteroscope when the foot pedal is deployed. The purpose of this study was to compare the flow and pressures created by the Peditrol with those of commonly used methods of irrigation. MATERIALS AND METHODS Flows through a flexible 6.9F Olympus ureteroscope (F-URS) and a 7...
Current study was carried out with aim to evaluate the effect of pressurized irrigation methods and furrow irrigation method with municipal effluent on distribution of salinity and moisture in the soil profile. The experimental study was designed by split plot layout with three irrigation methods including furrow, surface drip (SD) irrigation and subsurface drip irrigation (SSD) and two water q...
Sustainability and efficiency in irrigation are essential the management of water–energy–food nexus to reach Sustainable Development Goals 2030. In systems, reduction energy consumption is required improve system consequently sustainability indicators water network. The use pumps working as turbines (PATs) has been a feasible solution recover excess where pressure valves installed. This researc...
