The paper is devoted to the study of deflector nozzles rain irrigation machines. selection parameters nozzle artificial sprinkler machines on a scientific and practical basis allows for correct organization ecologically safe irrigation. article presents results research short-distance with deflector.

Impact of drip and overhead sprinkler irrigation on the persistence of attenuated Escherichia coli O157:H7 in the lettuce phyllosphere was investigated using a split-plot design in four field trials conducted in the Salinas Valley, California, between summer 2007 and fall 2009. Rifampicin-resistant attenuated E. coli O157:H7 ATCC 700728 (BLS1) was inoculated onto the soil beds after seeding wit...

Environmental monitoring is a significant driver for wireless sensor communication. Its potential to provide dynamic real-time data about monitored variable will enable to measure properties that have not previously been observable. A low cost consumer version soil moisture monitoring system was built using a gypsum block to take moisture readings, a peripheral interface controller (PIC) with a...

factor  is introduced for direct head loss calculation and sizing in dual-diameter laterals of sprinkler and trickle irrigation systems when the hazen-williams equation is to be applied. application of this factor prevents trial and error and uses fewer head-loss equations in calculating the total friction loss and designing dual-diameter laterals. the proposed factor is a function of total num...

In the evaluation of the risk of pesticide leaching to groundwater, the soil surface is usually assumed to be level, although important crops like potato are grown on ridges. A fraction of the water from rainfall and sprinkler irrigation may flow along the soil surface from the ridges to the furrows, thus bringing about an extra load of water and pesticide on the furrow soil. A survey of the li...

Abstract In the presented paper, we evaluated quality of work and economics use irrigation system consisting micro-sprinklers. The experiment took place on football field in countryside southwest Slovakia. original was replaced with a modern one, using control unit, rainfall sensor, in-ground distribution pipes consisted components forming main detailed equipment for irrigating an area 4,272 m ...

The improvement of irrigation systems in the Nile Delta is one of the most important attempts in Egypt to implement more effective irrigation technology by improving the existing irrigation networks. Demand delivery system in the existing irrigation network is using of mechanical gates structures to automatically divert water from one portion of an agricultural field to another in the desired a...
