homa State University Research Station in Goodwell, OK to measure volatilization losses of ammoniacal N Irrigation of swine effluent is one of the most economical ways to from swine-effluent applied to the land surface by flood dispose of swine manure. The determination of appropriate application rates requires the quantification of volatilization losses of ammoirrigation. Wu et al. (2003) deve...

Methods of modifying the water distribution pattern of an impact-drive sprinkler are described. A method of pattern modification called intermittent diffusion is introduced. A deflector attached to the drive arm intermittently diffuses the jet of a standard circular-orifice nozzle, producing desirable pattern shapes while maintaining a large pattern radius. Uniformity of application for both wi...

Scarcity of fresh high-quality water has heightened the importance of wastewater reuse primarily in dry regions together with improving its efficient use by implementing the Subsurface Drip Irrigation (SDI) method. Sustainable effluent reuse combines soil and plant aspects, along with the maintainability of the application system. In this study, field experiments were conducted for two years on...

Dairy manure increases the yields of dry bean (Phaseolus vulgaris L.) and spring wheat (Triticum aestivum L.) from eroded, furrow-irrigated soils and may increase corn (Zea mays L.) silage yield from steeper eroded areas under sprinkler irrigation. In a 2-year field study in southern Idaho on Portneuf silt loam (coarse silty, mixed, superactive, mesic Durinodic Xeric Haplocalcid), the effects o...

reduce the amount of water used, resulting in savings Low-pressure sprinkler irrigation systems have the potential to of both water and energy. save energy, but also may aggravate soiland water-management Center-pivot systems with high pressure nozzles reproblems. The objective of this research was to determine the influquire relatively large amounts of energy to develop ence of center-pivot sp...

Introduction In modeling real world tasks, one inevitably has to deal with uncertainty. This uncertainty is due to the fact that many facts are unknown and or simply ignored and summarized. Suppose that one morning you find out that your grass is wet. Is it due to rain, or is it due to the sprinkler? If there is no other information, you can only talk in terms of probabilities. In a probabilist...

Current regulations for fire suppression systems in underground coal mines to protect conveyor belt installations have been in place since the Coal Mine Health and Safety Act of 1969 was enacted. Over time, the coal conveyer equipment being used and ventilation conditions underground have changed significantly, particularly the width of the conveyor belts and the use of belt air at the face. Th...

for the proper use of water resources in agriculture, it is necessary to provide appropriate irrigation system to supply crop water requirement. in the present research, using a hierarchical analysis, different types of irrigation systems were evaluated and prioritized on 1150 hectares of agricultural land of etka organization ​​ located in dorud, iran. hierarchical analysis process is one of t...

are fitted overhead in the various departments. The number and size of the sprinkler tanks vary according to the requirements of each mill, hut 011 an average each tank is from 30 feet to 60 feet either way, and carries permanently about 6 feet of water. The water is mostly a clean supply derived from the municipal mains, though an emergency connection with the millpond by means of a pump is al...
