  • Managing Iron Deficiency Chlorosis in Soybean

    Iron in leaflets can be greater in the chlorotic plants than non-chlorotic plants because of an accumulation of iron in the leaves and the plant's inability to reduce the iron III into an available form. Both cases increase IDC.

  • Ecological Soil Screening Level for Iron

    ferrous iron to plants, while oxidized environments (upland or well-aerated soils) promote the precipitation of ferric-oxide compounds, which are not available to plants for uptake. If excess ferrous iron occurs, iron toxicity may occur in plants, but this is highly dependent upon plant species.
