DURING the course of an investigation on the effects of land use on soil and water conservation, considerable data have been obtained on soil and air temperatures on woodland, meadow, and cultivated watersheds. The purpose of collecting these data has been to obtain information on all factors that influence the hydrology of small watersheds. The effect of frost in this connection is well known. In unfrozen soils, temperatures affect soil water movement indirectly through their influence on germination of seeds, plant growth, transpiration, evaporation, condensation, and percolation. The influence of temperatures on viscosity and surface tension may apply to percolation of water through soil. The effect of soil and air temperatures on agricultural hydrology is not a simple one because of the indirect effects of temperatures on various factors affecting the growth of plants and on soil water movement. Examples of such indirect effects are the influence of soil temperature on microbiological activities, on the rate of organic matter decomposition, and on plant diseases. Requests from widely scattered sources for information on soil temperatures have encouraged the presentation of a summary of the soil and air temperatures given herein.
