    Proposal summary:

    There is evidence to suggest that UV-C light, a type of ultraviolet, may be useful in controlling plant growth. The farmer will experiment with the UV-C lamp on ragweed, chickweed, Canada thistle, and winter rye using various exposures and recording the results. If UV-C light is effective, it may make no-till methods available to organic farmers, since cover crops can be managed without the use of herbicides.
