Those CEC values are really low.  And there is a wide spread between soil pH and buffer pH.  Is that a sand/ sandier soil type? 

Don't overload the fertilizer rate in one trip.  Consider spoon-feeding on 2 or 3 trips.  Think about meeting expected crop removal and not much more.  With those low CEC values, you don't have a lot of room on the soil colloid to retain nutrients, especially things like nitrogen, potassium, Sulfur, positively charged nutrients.
