Crops need more zinc, but negative interactions with other fertilizer makes applying it tricky. Research out of Australia ...

Heat causes a fusion of zinc and copper to form brass (gold-colored). Brass is 60-82% Cu and 18-40% Zn. In the hood, transfer 5-10g zinc dust or fine granular zinc in a 3.5 inch crucible with handle.

"However, the CLS beamline enabled us to understand that the agronomic performance cannot be predicted based on what form of zinc is present in the fertilizer granules. Instead, the pH drives the ...
