CEC number on soul sample results

Setting studying results trying to get straight in my head why some fields that look good on paper are not such good yielders. And some that look like dogs turn out pretty well. I don't have a yield monitor or GPS to make maps but I'm still a small enough operation to remember which fields do good. One thing I can't remember is what is CEC and what does it really mean. I think it's cation exchange. I know it has to do with how much nitrogen soil can hold. Just can't remember how to use the nber on the results.
