D)boron
E)all of the above

Question

Quizplus · Accepted Answer

Soil redox potential affects the availability of manganese by either making it more available or less available depending on the conditions. High redox potential creates an oxidizing environment that promotes the conversion of Mn2+ to Mn3+, which has limited solubility and is less available to plants. Conversely, low redox potential creates a reducing environment that promotes the reduction of Mn4+ to Mn2+, which is more soluble and available to plants. Zinc, cobalt, and boron availability are not commonly affected by soil redox potential.
