Soil temperature measurements made at Iowa State College in connection with studies in the germination of tree seeds, indicated that soil temperature at various depths under maple-linden cover was lower throughout the winter than it was under shrub cover (Meginnis). As this was at variance with measurements taken in the more mesophytic regions of eastern United States and Europe, a more careful study of the effect of different types of plant cover on soil temperature was considered advisable.
