Intensity and frequency of PyOM addition effects on soil properties were tested. Higher intensity of PyOM addition increased Mg but decreased Fe, Mn, and Cu. Higher frequency of PyOM addition increased Mg but decreased Mn and Cu. Intensity and frequency of PyOM addition affected soil pH but not pHBC.
