.. <br />• ~ In summary, the very rapid and complete drying of the soil profile <br /> during the early summer limits the conclusions that rnn be drawn cancera- <br /> iag the effectiveness of mulches in retaining soil moisture. It appears <br /> that the steeper, north-facing slopes retained more soil moisture than <br />•- the corresponding south-facing treatments. Excelsior and hydromulch <br />' provided some apparent benefit in retarding eater loss as compared to <br /> the control, although the results are not entirely consistent. The <br /> fall data suggest that the mulches may permit a greater amount of eater <br /> to ia£iltrate deeper into the profile as compared to the controls. <br /> 3.1.2 Soil Temperature <br />! This discussion is based upon soil termperature data obtained from <br />i~ May 3. 1978 to October 28, 1978. Soil moisture-t®perature cells were <br /> buried at 5, 15, 25, and 50 centimeter intervals into the soil/refuse <br />~~ materials on the test plots. Readings were taken every 14 days between <br />l <br /> 3:30 and 5:00 pm Mountain Standard Time. <br />• Acceptable data vas obtained from all but the 4:1 plots. Rain and <br /> vied contributed to the degeneration of tape markers attached to the <br /> probe leads. Apparently, from the results obtained on the 4:1 plots, <br /> the leads may have bees mislabeled through time which contributed to <br /> erratic data. The decision to disregard these data in this year's <br />,_ analysis stemmed from this problem. An attempt to salvage 1978 data <br /> will be made on future trips to the plots by exhuming the buried cells <br />` to determine which data sets are representative of specific depths. <br />Data reported in the following discussion are taken from cells <br />L <br />located on the vest 2:1, level, and north and south 2:1 plots. The <br />data gathered on these plots are considered valid and free of errors <br />in the labeling. The data for each plot were graphed with temperature <br />22 <br />
