Bad time of the year, especially in Pa. to try to start a food plot. Until you said that theresearch paperhad to be completed in late April the ideas of two or more plots with some cages over 1 sq yard areas, using different seeds and getting the grazed tonage figures figured out would have been good. I read a study in the QDMA magazine a year or so back that addressed this and it was interesting. Feeding with several troughs and noting the amount of feed preferred/consumed is an idea.
