Cation Exchange Capacity in soils may be related to texture because
a. Texture is directly related to nutrient availability
b. The ability to hold and exchange cations increases with particle size
c. The colloidal surface area of soils increases with clay content
d. Soil texture is indirectly related soil fertility
Soil acidity may be reduced by
a. Using chemical compounds that provide conjugate acids of weak bases
b. Applying compounds such as carbonates and silicates
c. Soil amelioration using composts
d. Using phosphate fertilizers
One of the principles that govern Cation Exchange Reactions states that
a. Calcium ions may replace aluminum ions on the exchange complex on an ion-by-ion basis.
b. The presence of anions in the soil solution does not affect cation exchange reactions
c. Each exchange reaction is likely to proceed to the right if the released ion is not prevented from reacting in the reverse direction
d. The lower the charge the stronger the cation will be held at the exchange site
