Water Storage and Movement

Question 1

water storage is affected by

Answer 1

unique chemical structure of water, neg charge of clay, combination of adhesion and cohesion

Question 2

stauration

Answer 2

point where water fills all pore spaces leaving no room for air. water moves through soil profile due to gravity

Question 3

field capacity

Answer 3

max amount of water that can be held in the soil against the force of gravity

Question 4

permanent wilting point

Answer 4

air takes up most of the pores and the water is held to soil so tightly that plants can’t access it

Question 5

plant available water

Answer 5

difference between field capacity and permanent wilting point

Question 6

gravitational/saturated flow

Answer 6

rapid movement through macropores only flowing down

Question 7

capillary/unsaturated flow

Answer 7

water movement through adhesion and cohesion through micropores can flow in any direction
