Investigates the effects of long-term fertility management on the dynamics of fixed and exchangeable ammonium (NH4) and potassium (K) in a typical Upper Midwestern agricultural soil. Relation between the chemistry of NH4 and K in soil; Effect of long-term fertility management on levels of exchangeable NH4; Fixation capacity of ammonium and K.
