C)well drained humid region loamy sand,pH 5.0
D)muck soil (Saprist)with pH 5.5
E)poorly drained calcareous soil with pH 7.6

Question

Quizplus · Accepted Answer

Manganese toxicity is most likely to occur in acidic soils with poor drainage. Option A fits this description as it is an Ultisol with a low pH (4.3) and is subject to frequent flooding, which can cause poor soil aeration and increase the availability of manganese to plants. The other options have either higher pH levels or better drainage, making them less likely to experience manganese toxicity.
