Micro Hume

Micro Hume supplies key trace minerals in a form that will not tie up readily in soil. Contains 5% calcium, 8% sulfate, 2% manganese, 3% zinc, 2% boron, and 1% copper. When all listed trace minerals are low, apply 50-200 lbs. per acre. Be very cautious with using high rates in greenhouses – the boron is very effective. If only a few of the trace minerals are low, consider using individual ingredients.

Disclaimer: OMRI listed. NOP approved with restrictions on manganese, zinc, boron, and copper.
