In a greenhouse experiment eight Southeastern soils were amended to give pH levels of 4.8, 5.8, and 6.8 and were treated with 0, 25, and 50 ppm Mn. After growing wheat (Triticum aestivium L.) for 40 days, the soils were extracetd for Mn using six extractants: H2O, neutral 1N NH4OAc (with and without 0.2% hydroquinone), "double acid", diethyle-
netriaminepentaacetic acid (DTPA) and ethylenediaminedi-o-hydroxyphenylacetic acid (EDDHA). Except for the low-Mn soils, greater differences in extractable Mn were observed among soil types and soil pH levels than among Mn rates. Extractable Mn was
correlated with soil clay content and total soil Mn. Organic matter content with a narow range from 1.0 to 2.9%, silt content and cation exchange capacity (CEC) were not correla-
ted with extractable Mn. The extractable Mn decreased as soil pH increased for the H2O,
NH4OAc alone, and DTPA extractants making them preferable for predicting soil Mn availability since higher pH causes Mn to be less available to the plant. |
