Only apply zinc where soil tests confirm deficiency below 1 ppm Zn. Blanket application on adequate soils returns negative ROI at current prices.
Zinc is mined in Australia, Peru, and China; mine production affects fertilizer-grade supply.
Corn removes 0.1–0.15 lb Zn per bushel; high-yield corn in deficient soils drives steady demand.
EDTA chelate commands a 3–4x price premium but is required for calcareous soils.
Zinc is used in galvanizing and batteries; fertilizer-grade competes with industrial demand.
