Determination of plant-available manganese from soils by acid ammonium acetate-EDTA extraction
Manganese was extracted with a solution containing 0.5 M NH4-acetate, 0.5 M acetic acid and 0.02 M Na2 -EDTA at pH 4.65 (AAAc-EDTA) from 86 soil samples collected from plough layers in Finland. The results were compared to the quantities of exchangeable, reducible (three methods) and total Mn of the...
