Nitrogen for Corn Silage

Pivot Bio PROVEN® 40

The world’s most produced crop, corn is also the most dependent on nitrogen fertilizer. Available on-seed or in-furrow, PROVEN® 40 provides a more predictable, productive nitrogen for corn, delivering steady nutrition at the root throughout the most critical growth stages, regardless of weather and soil.

    PROVEN® 40 eliminates corn nitrogen deficiency and delivered over 25 tons/acre, nearly a ton more than farmer standard practice.

  • More Sustainable Nitrogen

N-OVATOR™ for Farmers

Using Pivot Bio microbial nitrogen is better for plants and the environment, eliminating nitrogen leaching and volatilization into the atmosphere. We created the N-OVATOR™ program to incentivize and reward farmers for their synthetic nitrogen reductions and environmental impact.

What Farmers Have to Say

Feed quality for a dairy cow is tremendously important. Last year we heard about PIVOT BIO PROVEN 40® and did about 1,000 acres and really liked what we saw. This year we did all 3,000 acres of corn and will continue to do all the acres of corn for the foreseeable future.

NLIGHTEN® Your Bottom Line

Pivot Bio’s NLIGHTEN® in-furrow tank system mounts on your existing planter to deliver the precise amount of microbial nitrogen, right at the root, on every acre. Through the NLIGHTEN® equipment reimbursement program, farmers can offset the cost of in-furrow equipment when they use PROVEN® 40 or RETURN®, making it easier to replace synthetic nitrogen with our more predictable and sustainable crop nutrition.
