Pneumatic Applicator for Uniform Distribution of Dry Fertilizer on Small Plots1

  1. G. E. Varvel and

Uniform distribution of dry fertilizer materials on small plot areas has been a problem for many years because most of the equipment has been developed for field application. Recent developments of pneumatic herbicide and fertilizer application equipment have been made which allow uniform distribution of these materials over various size areas. These developments made components available which were used to construct a small-plot applicator to broadcast or inject dry fertilizer. This applicator accurately and consistently metered and distributed three fertilizer materials which varied in particle size. The use of air to distribute the fertilizer also permits various applicator widths with the same machine.
