GOOSEPILOT - 1/13/2021 09:36 I would guess most would blend in zinc sulfate. I dont agree with that personally. 10 lbs per acre equates to 1 prill per 3 square foot. It's not likely to stay blended when such big density differences from other products in the blend. Here anyway we deal with cool soils and zinc is needed early, often when soils are less than 65 degrees. Zn is 5x more available at 65 than 50, so liquid in furrow is insurance that some is plant available. If zn is less than 1 ppm, then I would say to use mesz.
Are you talking 10 lbs of product or 10 lbs of zinc?
Product. I've seen recs and guys blending 10-20lbs with npk. Or in a micro bin is much better app but still not going to impact a crop.
