Optimum starter placement

Getting the right nutrients to seedlings early in the season is a challenge because fall-applied fertilizers limit the plant’s uptake in the spring. FurrowJet firms the seed in the trench while placing bands of fertilizer on and near the seed, so early roots can access essential nutrients at the perfect time, ensuring that plants are never hungry.

Phosphorus Doesn't Move

Phosphorus fertilizer does not move in the soil, which means that it needs to be placed where a plant will be able to access it.  Broadcasting the immobile nutrient across the entire field doesn't make sense, because it won't move to the rows where the plants are.  

Phosphorus is Needed Early

Phosphorus is responsible for cell division and elongation and is needed early in a plant's life in the highest quantity.  Considering the lack of movement of the fertilizer and the plant's need for P early in it's life, it makes sense to apply a phosphorus starter with the planter.  Seedling roots and early crown roots of some crops will take up phosphorus; thus determining the ideal placement of the fertilizer.  Feeding the soil in the fall and hoping to get some of the nutrient back for the plants in the spring can be improved upon by moving some of the fall application to a planter applied band.

Place Phosphorus Perfectly

Putting starter where the plant needs it, when the plant needs it, takes FurrowJet.  FurrowJet is a planter mounted device that places three bands of phosphorus starter fertilizer near the furrow; one in furrow, and two about 3/4" away from the seed on either side.  These three bands are placed right where the seedling roots and crown roots will grow, taking up the P and thriving.

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.
