In highly acidic pH, the following nutrients are available in toxic amounts in soil:
(A). Fe
(B). Mg
(C). Mo
(D). Mn
Choose the correct answer from the options given below:
Show Hint
Except for Molybdenum, the availability of all micronutrients (Fe, Mn, Zn, Cu) increases as soil pH decreases.
Under highly acidic conditions, Fe and Mn solubility increases so much that they frequently reach phytotoxic levels.
