Nitrogen for Corn Silage

Pivot Bio PROVEN® 40

Corn, the world’s most produced grain crop, 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 plant root throughout the most critical growth stages, regardless of weather and soil type.

    PROVEN® 40 eliminates corn nitrogen deficiency and delivers over 22 tons/acre, nearly a ton more than farmer standard practice.

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.

Pivot Bio’s NLIGHTEN® in-furrow tank system mounts on your existing planter to deliver the precise amount of microbial nitrogen 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 incorporate Pivot Bio products into their nitrogen management plans.
