Zeolite does not remove heavy metals from soil, it binds them in place. What published studies show for cadmium, lead and zinc, typical rates, the limits, and bulk supply terms.

Published field research on natural zeolite for corn: +0.93 t/ha at 500 kg/ha and +1.36 t/ha at 2,000 kg/ha, with bigger gains alongside nitrogen. Plus application rates, fractions and bulk supply terms.

Recommended inclusion rate for activated zeolite ZEOL: 4–6% of dry feed mass for all farm animals and poultry, how to convert it into kg per tonne, and how to introduce it to young pigs.

Independent lab data: natural zeolite bound 100% of aflatoxin B1, 25% of zearalenone and 5% of T-2 toxin. What this means for feed producers.
