I want to know the answer to the following question:
How is zinc primarily added to soil?
All the background I'm provided with is that "Zinc is primarily added to the soil through the weathering of rocks, but humans have added zinc through fossil fuel combustion, mine waste, phosphate fertilizers, pesticide (zinc phosphide), limestone, manure, sewage sludge, and particles from galvanized surfaces.". Is that enough to answer the question?
Answer: yes
