Field test of an automatic controller for solid-set sprinkler irrigation

Simulation of a collective solid-set sprinkler irrigation controller

8 The modernization of irrigation districts in Spain is based on the construction of 9 collective pressurized networks equipped with remote control systems. In this paper, a 10 simulation approach is used to explore the benefits of introducing a collective solid-set 11 irrigation control software. The controller works in combination with a district 12 management database, real time evapotranspi...

design of an analog fuzzy logic controller chip

fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...

Sprinkler and mist irrigation for cooling lettuce:effectiveness and economic cosideration

Sprinkler Irrigation: a Voc Remediation Alternative

A sprinkler irrigation system was tested to assess its efficacy for volatilizing organic chemicals in pumped groundwater. In field tests involving the analysis of more than 250 samples collected from beneath a spray irrigation system, removal rates of ethylene dibromide (EDB), 1,1,2-trichloroethylene (TCE), 1,1,1-trichloroethane (TCA), and carbon tetrachloride (CT) in samplers placed 0.5 m abov...

Test-plot studies on runoff of sulfonamides from manured soils after sprinkler irrigation.

Three test-plot series have been performed to gather information on runoff of sulfonamides from manured arable and grassland after sprinkler irrigation. To prepare test slurries with defined aged residues, liquid bovine manure was fortified with sulfadiazine, sulfadimidine, and sulfamethoxazole and stored short-term. After test-slurry application, the arable land was treated by soil cultivation...
