Solution
The Cation Exchange Capacity (CEC) of a soil is a measure of the soil's ability to retain and supply cations to plant roots. It's calculated by summing the amounts of exchangeable cations a soil can hold.
Given the information, we can calculate the CEC of the soil by adding up the meq/100g of each cation:
Al3+ = 5 meq/100g H+ = 2 meq/100g Ca2+ = 3 meq/100g Mg2+ = 3 meq/100g K+ = 3 meq/100g Na+ = 3 meq/100g
So, CEC = 5 + 2 + 3 + 3 + 3 + 3 = 19 meq/100g
Therefore, the CEC of the soil is 19 meq/100g.
