Suppose your topsoil has a cation-exchage capacity of 8.1 cmol(+)/kg soil and a bulk density of 1.45 g/cm³. What is the potential storage capacity of 6.0 inches of this topsoil for calcium? Please calculate one measure of this capacity: If the CEC were empty of calcium, then how much CaCO3 (in tons CaCO3/acre) would you have to add to the top 6.0 inches of soil to add 100% of the CEC as calcium?
