also my understanding on spreading nitrogen is your CEC cation exchange capacity X 10 is the amount of nitrogen the ground can absorb at one time. for example your cec is 7, anything more than 70 pounds of nitrogen would be lost. that may be BS but thats what i was going by when i spread ammonium nitrate
Cation exchange capacity (CEC) is the ability of your soil to hold cations (Potassium, Calcium, Magnesium, etc). This is the first time I ever hear of it being used to calculate Nitrogen applications. And I can't think of a reason that it would be used for that purpose. CEC is used in calculating the affects of liming has on soil pH.
