gromi~ plants. This hypothesis is supported by a pattern of consis- <br />•` featly higher near-surface soil voisture wader control plots on both <br /> asxrts_ Plant density and production on control plots vere generally <br /> mach laars than adjacent mulched plots (Table 3.4.1), suggesting that <br /> greater soil moisture under the controls may be a consequence of lower <br />' ester.,r;7;+~tian by a sparse plant papulatian. <br />- ~e pattern of deep (50®) moisture levels is difficult to relate <br /> direttly to the effects of mulches and aspects. It appears that soil <br />_. ~ois•~me relations deeper in the refuse material are being affected by <br /> factars that are not directly attributable to surface manipulations. A <br /> pnssihle tpnfaunding factor was a large puddle at the east end of the <br /> plots that persisted through the late spring. The soil moisture results <br /> do not shov any pattern that could he attributed to the direct effect of <br /> tlias pa3dle. The TBEME and 4DSM5 treatments were adjacent to the <br /> puddle_ Both treatments dried onL at all depths by 3uae 30, a result <br /> ~++~+~+~tsat with the behavior of other aloe not adjacent to the puddle. <br />' Tg data suggest that the excelsior tmleh may retard the entry of <br /> neoisz~-^e frem light precipitation more than either the control or hydro- <br />r <br />j.) <br />mala$ on santh aspects.
