2. Name and describe three potential fates of water after precipitation on the soil surface. (3)+surface runoff: water does not infiltrate, runs over ground surface, picking up dissolvable

pollutants or soil (erosion)+infiltration: movement of water into soil+drainage: water moves through soil profile and out of root zone (leaching)+evaporation: water vaporizes directly from soil to air+transpiration: water is taken up by plant, used in plant metabolism, and is released through leaves+percolation: water moves downward into soil profile+soil storage: water remaining in soil due to matric potential+capillary rise: water movement back into profile from water table during

periods of dryness3. What hydraulically significant properties should a prime site for agriculture include? (2)+level, not too sloping+well drained+deep and permeable +moderate infiltration rates+no impeding horizons+ample water storage capacity4. Use a diagram to explain the difference in water content at field capacity and at the permanent wilting percentage. (3)
