| Abstract/Contents: | "Two weighing lysimeters have been installed at the University of Arizona Karsten Turfgrass Research Center for researching the consumptive water use of turf, nitrogen fertilizer loss through leaching, and solute transport through a fine sand soil profile. Each tank is 13.1 feet deep and 8.2 feet in diameter, and has a soil-filled weight of approximately 99,120 lb. Each tank has sampling ports in groups of five which are spaced at 120° around the tank. These ports begin at the 3.3 foot depth (level) and are then every 1.6 feet down to a depth of 11.5 feet. Tensiometers with pressure transducers, TDR probes, and ceramic and stainless steel solution samplers have been installed three each to a level. A single neutron probe access tube was installed in the center of each lysimeter. These devices are used for sampling soil water and monitoring soil moisture content. A Cardinal scale with an electronic loadcell measures changes in tank weight to ± 0.44 lbs (0.002 " water loss or gain). A Campbell CR-7 is used for Analog/Digital conversion for the transducers and loadcell, and a single computer program has been written to import, analyze and manage the data. Data are available for viewing and retrieval in real time. Land preparation (deep ripping, mulch incorporation, rock removal, grading) is beginning on the site in preparation for irrigation system installation. A dual irrigation system has been designed for the site so that each lysimeter can receive either wastewater or potable water. A wind speed shut off switch and zero trajectory heads are to be installed to prevent drift. The lysimeter computer will also be able to shut the irrigation system off when a predetermined amount of water has been applied. The remainder of the irrigation system, i.e. that irrigating the surrounding turf, will also be controlled by the wind speed shut-off switch. A M.S. graduate student was hired for this project in August, 1994. Mr. Duane Otto has a B.A. in Agribusiness and a Mathematics minor from Mid-Nazarene College in Olathe, KS. His work experiment with Turf Diagnostics and Design has given him experience in soil physical measurements. He is currently in his first semester of coursework." |
