Abstract

Abstract

The application of liquid fertilizer and other solutions to small experimental areas creates a problem because most equipment is constructed for farm a plication. There was a need for a small plot applicator tiat would accurately dispense liquid fertilizer 10-34-0, as well as other solutions. A two-row cultivator (Pittsburg) frame was equipped with a system activated by carbon dioxide. A 19-liter stainless steel tank (Firestone) was used for mixing chemical solutions.

This system allows surface and subsurface application of fertilizer solution and can easily be converted to a sprayer for application of solutions to plant foliage. Various combinations of solutions, rate, and pressure are available to meet the applicator's specifications.
