Joe Rosenberg Testimonial


"This year we had decent planting, but then it got really wet. We finished harvesting about 2 weeks ago. I used Envita on part of my field, about 600 acres of corn and the corn was 4 points drier and the ears were further along. I also used it on 600 acres of beans.

I also had 40 acres of another biological product and I couldn’t really tell the difference in the corn or the yield. It was also difficult to apply. I won’t be using it again next year.

I really like the application process with Envita, I didn’t have to spend as much time mixing anything up. I would definitely recommend this product, and I already have. The results really surprised me, our corn was about 4 points drier than where we didn’t use Envita, which meant less gas needed to dry out our crops. I could tell exactly where I used Envita and our yield numbers were great. I also used Envita on some soybeans and noticed how much faster they came out of the ground."

2 corn in furrow trials


Trial 1: 31 bu/ac (13.96%) yield increase with Envita

Trial 2: 5.44 bu/ac (2.44%) yield increase with Envita

2019 Acres booked: 1600

“Envita gives me the chance to fix what I don’t have a chance to do myself, whether it’s too much rain or we have other delays. So many things can go wrong on any given day, it’s good to know with Envita the plant can hold itself until I get there. You don’t want the plant to suffer because our timing is off.

It’s no different than us. We all need to stop for lunch and supper. The difference is, the plant doesn’t have all the options we do. It’s stuck in one spot and can only access the nutrition available. Envita gives me extra peace of mind that the plant is getting the nutrients it needs.

I’ve been excited for this stuff (Envita) to come along. I’m using it on all 1600 acres of corn next year and trying it out on some beans. I know it won’t always make that big of a difference everywhere, but it will be enough to make it worth it.”
