Variable-rate (VR) liquid nitrogen injection
applicator. This was built by the Biosystems and Agricultural
Engineering Department to be used for VR nitrogen studies in
cooperation with Agronomy and Agricultural Economics. A John-Blue
piston pump, Rawson controller, and laptop computer are used for
varying application rates. |
