44. Which statement is NOT true about kaolinite and kaolinitic soils?
A) Bonding between sheets in kaolinite is very weak, thus kaolinitic soils are easy to
plow.
B) Kaolinitic soils do not shrink and well as there is no interlayer swelling.
C) There is no interlayer welling in kaolinite, so kaolinitic soils hold less water than
other clay-rich soils.
D) Kaolinitic soil is useful for agriculture if nutrients are managed properly.
E) There are cations in between the layers of kaolinite.
is the amount of exchangeable cations per mass of soil and its unit is in
milliequivelents (meq) per 100 g of oven dry soil.
D) Anion Excha
E) lonic stren
