Answer to Question 1

See Table 9-1 in text.

Answer to Question 2

CEC is a measure of the fixed negative electrical charge in root
substrate. Since many nutrients are positively charged they are held in root
substrate on the fixed negative charges. While these nutrients are protected from
leaching they remain available for plant uptake.
