We have investigated the factors influencing Mn release in an acid soil and to better understand the Mn dynamic and uptake by maize seedlings. Soil preparation processes (air-dry, oven-dry, storage, etc.) significantly influenced Mn availability. Soil Mn extracted by 1M NH4OAc pH 7.0 was highly correlated with plant Mn. The use of a soil sample without drying seems promising for evaluting soil-available Mn but the procedure still needs widespread evaluation.  aAcid soils  aCorn  aManganese  aManganês  aMilho  aSolo Ácido  aSolubilidade1 aPAVAN, M.
