Roller, W L; Elwell, D L

A three-year study of the beneficial use of simulated power plant reject heat for soil heating in greenhouses is described. The effect of 25, 30, 35, and 40/sup 0/C warm water on the temperature of and moisture distribution in three diverse, greenhouse soils was studied, and the growth response of variety HR-5 lettuce in this environment was determined. Detailed information on soil temperature and moisture distribution, heat transfer rates, and lettuce production yield under various operating conditions was obtained.
