• e. 2:1 Slopes - West (Appendix B-16, B-17) , There were no important moisture differences over time between excelsior and hydromulch on this aspect. The bay 4 Scm mois- ture was higher under hydromulch than excelsior, a patters seen previously. f. Level Slope - Refuse vs. Topsoil (Appendix B-13, B-14) fiery large differences were observed between the topsoiled sad refuse plots. The topsoiled plot showed a pattern very similar to that of adjacent 4:1 slopes. The refuse plot showed moisture levels between 5X and 15X for the entire growing season for the 15-50cm depth. This anomalous pattern duplicates the 1978 results. These refuse plot results are attributed to either anomalously high moisture levels, or unusual chemical characteristics of the refuse material. g. 4:1 x 2:1 - North (Appendix B-1 through B-3, B-7 through B-9) There were no important differences in soil moisture curves between these two slopes. Early spring moisture ranged be- tween 15X and 20X at all depths in early spring and moisture declined between 5X by June 3D at all depths except the 50cm, regardless of slope or mulch treatments. The highest early ~ spring moisture level at 5® was recorded under the 4:1 north control. h. 4:1 x 2:1 - South (Appendix B-4 through B-6, B-10 through B-12) There are few differences in the soil moisture curves over ~. time between slopes. Early spring moisture on the 4:1 slopes vas slightly higher at all depths (generally above 15X) than the 2:1 slopes (15X or below). Exceptions were the 4:1 excel- sior plot, on which soil moisture was less than 15X at all depths except 15~ on riay 4; and the 2:1 control plot oa which soil moisture was above 15X at all depths on riay 4. Soil moisture declined below SX on all treatments regardless of slope at all depths except 50® by the end of June. .• 15
