Water savings through surge irrigation, 1994

Creator:: Shock, Clinton C., English, M. J., Mittelstadt, R. W., Shock, Byron M., Oregon State University. Malheur Experiment Station, and Oregon State University. Agricultural Experiment Station
Abstract:: Stephens winter wheat was grown using conventional furrow irrigation and surge irrigation on 12 one-half-acre plots. Both systems were operated simultaneously four times during the season. Conventional irrigation applied 26.5 ac-in/ac of water with runoff of 0.8 ac-in/ac and infiltration of 25.7 ac-in/ac. Surge irrigation applied 13.7 ac-in/ac with 0.5...

Surge irrigation of wheat, to increase irrigation efficiency and reduce sediment loss, 1993

Creator:: Shock, Clinton C., Saunders, Lamont D., English, M. J., Mittelstadt, R. W., Shock, Byron M., Oregon State University. Malheur Experiment Station, and Oregon State University. Agricultural Experiment Station
Abstract:: Treasure spring wheat was grown using conventional furrow irrigation and surge irrigation on 12 one-half-acre plots. Both systems were operated simultaneously five times during the season. Conventional irrigation applied 24.7 ac-in of water with runoff of 5.6 ac-in and infiltration of 19.1 ac-in. Surge irrigation applied 12.0 ac-in with 1.7...

Improved irrigation efficiency and reduction in sediment loss by mechanical furrow mulching wheat

Creator:: Shock, Clinton C., Saunders, Lamont D., Shock, Byron M., Hobson, Joe H., English, M. J., Mittelstadt, R. W., Oregon State University. Malheur Experiment Station, and Oregon State University. Agricultural Experiment Station
Abstract:: Treasure spring wheat was grown on sloping ground with and without mechanically applied furrow mulching. Furrow mulching used 800 lb/ac of wheat straw. Mulched and non-mulched furrows were irrigated five times during the season receiving 483 and 19.0 and 40.9 ac-in of irrigation water, respectively. For non-mulched furrows, infiltration totaled...

Development of a decision support system for pond aquaculture

Creator:: Nath, Shree S.
Abstract:: Decision support systems (DSS) have been used to a very limited extent in pond aquaculture. This study documents the development of a DSS (POND) which allows representation of an entire pond aquaculture facility, and provides analysis capabilities in the form of simulation models and an economics package. Simulation tools in...

A comparison of drift from hooded and open-boom agricultural sprayers

Creator:: Fehringer, Ronald J.
Abstract:: A recent development in drift-control for agricultural ground sprayers is the installation of a hood (or shroud) over the boom. Hoods are designed to provide a protected zone in which droplets can be sprayed and deposited on the target with limited interference from the wind. This study compared chemical drift...

Field evaluation of passive capillary samplers in monitoring the leaching of agrochemicals

Creator:: Brandi-Dohrn, Florian M.
Abstract:: Soil solution samplers have certain inadequacies that limit their range of possible applications. Passive Capillary Samplers (PCAPS), which apply suction to the soil pore-water via a fiber glass wick, have shown promising results in preliminary experiments in regard to collection efficiency of water and of bromide tracers. The objectives of...

Using infrared canopy temperature and leaf water potential for irrigation scheduling in peppermint (Mentha piperita L.)

Creator:: Gallardo, Ivan T.
Abstract:: Several methods of infering plant water stress for irrigation scheduling are based upon measurements of the environment in which the plants grow. These measurements include parameters such as soil water content, air temperature, pan evaporation and incident radiation. It is hypothesized that improved estimates of plant water deficit can be...

Feasibility study for a Tillamook County dairy waste treatment and methane generation facility

Creator:: Edgar, Thom G.
Abstract:: With the expansion of the Tillamook Creamery, in Tillamook Oregon, to double or more its cheese production, the demand for milk presents an economic opportunity for the member dairies of the Tillamook County Creamery Association. Before area dairies can expand their herd size to increase milk production for the creamery,...

Flow characteristics of constructed wetlands : tracer studies of the hydraulic regime

Creator:: Stairs, Darrin B.
Abstract:: Treatment efficiency in a constructed wetland is related in part to the amount of time that a wastewater remains in the system. Current design methods idealize the system as a plug flow reactor and use a "residence time" based solely on the volume of the cell and the flow rate....
