The picture below is an example of 0.53 layer and ● oxygen silicon ● aluminum hydrogen Li 1.03 layer can join to form sheets. layer. 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. A) Cation Exchange Capacity (CEC) B) Total alkalinity
