FurrowJet: The Optimum Starter Placement
FurrowJet is a planter fertilizer attachment which enables you to place not only an in-furrow starter fertilizer, but also a dual-band of fertilizer 3/4″ on each side of the seed. FurrowJet rides in the furrow just above the seed, firming while placing starter. Wings on FurrowJet angle downward to cut into the sidewall and place fertilizer alongside the seed in a dual-band. By being near-furrow, this placement gives the seedling and crown roots immediate and continuous access to the nutrients. Combined with accurate placement, FurrowJet is flexible, allowing increased rates and common starters to be applied safely, avoiding seed burn risk.
Reduce Risk and Increase Yield
Today, yield response from starter is limited by the current in-furrow and 2×2 attachments. Due to fertilizer salt burn risk, rates for in-furrow pop-up attachments area very limited, capping the yield opportunity. Starter fertilizer placed by using 2×2 attachments is just too far away from the plant roots to be effective during early root devleopment.
By being near-furrow, FurrowJet’s placements give the seedling and crown roots immediate and continuous access to the nutrients.
Farm Journal Test Plot
Starter test plots were planted May 6 and 7 in 2016. Within 24 hours of planting, this field received excessive rainfall in a short amount of time, which played a role in the results.
“The large yield responses show the effect of starter fertilizer placement and the horsepower it provides to mitigate early season stress,” Ken Ferrie said. “The fact we were able to weatherproof this plot by replicating it across the field makes the large yield increases more believable.”
The first study was a comparison of the check to FurrowJet applying 3 gal in-furrow and 10 gal through the wings. The second study compared the check to in-furrow only, FurrowJet (tri-band) and a 2X2 with Keeton together.
