A soil has the following analyses:
CEC = 14 meq/100g
pH 5.5
exchangeable Ca = 5 meq/100g
Mg saturation = 5%
K saturation = 2%
Acid saturation = 57%
A soil lab recommended that the Ca, Mg, and K saturation be increased to 75%, 12%, and 8%, respectively.
Show all calculations.
a. Calculate the lbs/afs CaCO3, MgSO4·7H2O, and KCl required.
b. Calculate the initial and final BS%.
