available soil Mn, Mn deficiencies in corn were suspected on soils where Mn applications had previously increased
soybean seed yields. Five experiments were conducted
in farmer's fields to evaluate the response of
corn to Mn applications. Three band Mn and two broadcast
Mn studies were conducted in five field experiments
on Atlantic Coastal Plain soils. The mean increase in
corn grain yield in the band studies on three soils was
960 kg ha-1. Corn grain yields were not increased in
the broadcast Mn studies on Slagle and Dragston fine
sandy loams. Manganese uptake from the Slagle soil was
so high that Mn deficiency did not occur; whereas, Mn
uptake from the Dragston soil was so low that the deficiency
was not completely corrected by up to 24 kg Mn
hha-1 as broadcast MnSO4.
