Abstract
In pot experiments with a polder soil low in reducible Mn (extractant: 1N NH4OAc + 0.2% hydroquinone at pH 7), 50 kg/ha Mn applied as MnO (55 or 63.5% Mn) or MnSO4 (32.5% Mn) were as effective for preventing Mn deficiency in oats as spraying with MnSO4 or Mn-Rayplex (a polyflavonoid); reducible Mn in the soil increased to 50-60 ppm. With a more recent polder soil where Mn deficiency was not closely related to reducible Mn, but to C/N ratio, applying up to 176 kg/ha Mn did not completely control Mn deficiency.
