To conserve soil moisture, and increase soil temperature; mulch is used. This study established to evaluate the soil temperature, moisture and saved water due to the effect of three types of mulch; clear plastic, black plastic, and sawdust versus bare of clay soil in Jordan. Soil temperature and soil moisture were measured at three depths; 15, 30, 45 cm for each type for one month. Sawdust showed a highest average reading of moisture at 15 cm, the second was clear mulch followed by black mulch and at the lowest average for bare soil. The highest total saved water for sawdust. Soil temperature decreased with depth under the same type of mulch. Pearson Test showed a negative strong correlation between soil temperature and moisture for all treatment at (α= 0.01). Black mulch showed high correlation between temperature and moisture at depth of 30 cm. But sawdust and clear showed high correlation at 15 cm soil depth. Two tailed t-test showed that clear mulch had non-significant differences at α = 0.05 and α = 0.01 for all factors except temperature at depth of 30 cm and 45 cm respectively. Black mulch and sawdust showed significant differences for temperature. Black had strong significant in positive direction, which mean increased soil temperature, but sawdust is negative. Saw dust was recommended to use after the winter, black was recommended to use in summer and clear was recommended to use during winter and early spring.
