It is interesting to note, that you can tell what this soil is like in texture just by the CEC (cation exchange capacity).
3.8 is low, which means it is sandy or loamy sand, or basically a light/well draining soil. It is low in humus or organic matter, so there is less surface area for chemical reaction (or cation exchanging) to occur.
