Quiz 7 Answers 1. Soil A has a Ksat value of 8
cm/h, Soil B has a Ksat value of 0.00003 cm/h,
and Soil C is shallow and rocky and has a Ksat
value of 3 cm/h. a. which soil would be more
suitable for agriculture? (1) Soil A b.
which soil would be more suitable for wastewater
lagoon lining? (1) Soil B 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 soildrainage 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
dryness 3. 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 capacity 4. Use a diagram to
explain the difference in water content at field
capacity and at the permanent wilting percentage.
