Question

which chemical fertilizers replenish zinc in the soil​

Answer 1

Fertilizers with zinc sulfate, especially in its heptahy- drate form (e.g., ZnSO4. 7H2O), are the most common- ly applied zinc fertilizers due to the higher solubility and relative low cost of zinc sulfate. Zinc-oxysulfates and ZnO are also used in zinc fertilizers.
