Abstract/Contents:"Turfgrass canopy temperature (Tc) measured with an infrared thermometer (IRT) can be useful in irrigation scheduling and physiological studies on turfgrass. In using these methods, collection of representative and accurate measures of Tc is paramount. While using IRT under field conditions, we observed turfgrass Tc to be greater where large amounts of clipping debris were present. Research was undertaken to test the effect of clipping debris on Kentucky bluegrass (Poa pratensis L.) Tc and determine the relative duration of any effect if present. Turf was mowed at 5.1 cm when canopy height was 7.6 cm, in keeping with a widespread recommendation to not remove more than one-third the aerial shoot growth in a single mowing. Clippings were returned to the stand at 0, 1, 2, 4 and 6 times the fresh harvested rate. Turfgrass Tc was measured at 1300 hr on the day of mowing/clipping return and at the same hour 1 and 2 days after treatment (DAT). The experiment was repeated 5 times over the 1989 growing season at Urbana, IL. Turfgrass Tc increased with increasing clipping deposition in four of five experiments. Returning clippings at the 1x rate rather than collecting clippings had no significant effect on Tc in all five experiments. Clippings in excess of the 1x rate caused significant increases in Tc relative to turf where clippings were not returned, in four of five experiments. These results indicate that care must be taken in sampling of turfgrass areas where excessive clipping debris exist in order to obtain representative measures of Tc."
