    Proposal summary:

    Rising greenhouse heating costs are creating a burden for many northeast producers. The project manager will test using a compost pile adjacent to a greenhouse to heat water that will be used for under-bench heating of the greenhouse crops. B.T.U.s generated by the compost pile, transferred to water, and ultimately released in the greenhouse as heat will be calculated and plant performance will be noted. Costs of constructing and running the compost heating system will be compared to the costs of installing and operating a propane heating system. Outreach will be through presentations, the agricultural press, and farm visits.
