Importance of Balanced Nutrients

BioAg Management’s base in-season fertility products are formulated to provide the best balance of nutrients that are often lacking in corn. Through years of tissue and SAP testing, BioAg Management has determined that Nitrogen, Potassium, and Sulfur are often deficient, and adding these nutrients frequently yields the best ROI.

Nutrients Work Together

We often only consider Nitrogen in our in-season fertility passes, but understanding the synergy of other nutrients alongside Nitrogen is crucial. Sulfur plays a significant role in converting Nitrogen to protein in the plant. Adding Sulfur not only provides nutrition but also helps make the applied Nitrogen more efficient.

Nitrogen and Potassium Relationship

The relationship between Nitrogen and Potassium is also essential. As plant levels of Potassium decrease, the plant’s ability to uptake necessary Nitrogen also decreases. For this reason, BioAg Management recommends including Potassium in most in-season fertilizer passes. At BioAg Management, we believe that focusing on the right balance is key to successful fertility management.

Product Blends


NutriPrime NKS

NutriPrime – Key Benefits

  • BioAg Management has found that this nitrogen, potassium, and sulfur analysis is properly balanced for maximizing growth in corn plants.
  • Can be applied at high rates but is still cost effective.
  • Offers better mixability than other heavy sulfur fertilizers.
  • Contains all three main nitrogen forms: ammonium, nitrate, urea.


NutriPrime NKS

NutriCarb – Key Benefits

  • An energy efficient and balanced blend of nitrogen, potassium, and sulfur.
  • Offers better mixability than other heavy sulfur fertilizers.
  • Contains amine nitrogen, nitrogen that is bound by carbon, which does not require a lot of energy for the plant to utilize.
  • Contains no nitrate, good for nitrate sensitive crops.
  • Recommended for late season passes on corn.


NutriPrime NKS

KickStart – Key Benefits

  • Well balanced between Nitrogen, Potassium, Sulfur.
  • Great option for growers who have purchased bulk UAN and want to add sulfur and potassium to their mix.
  • Offers better mixability than other fertilizers.


NutriPhos Label

NutriPhos – Key Benefits

  • Well balanced blend containing Nitrogen, phosphorus, potassium, and sulfur.
  • Competitive price compared to other N, P, K, S fertilizers.
  • Blend is formulated to aid in a quick formation from polyphosphate to orthophosphate.
  • Contains all forms of Nitrogen: Urea, Nitrate, Ammonium.

BioAg Management’s Base Products

NitroSul – a liquid Nitrogen and Sulfur fertilizer:

  • Balanced 1:1 ratio between Ammonia and Sulfate
  • Nutrients are plant available at application, no conversion is required.
  • Includes higher amounts of Nitrogen than other Sulfur fertilizers, which allows reduced rates of UAN, especially when prices are high.
NitroSul label

CheckMate N – a liquid Nitrogen fertilizer with a nitrogen concentration of 21%:

  • Can be applied at high concentrations in foliar applications compared to other nitrogen fertilizers due to plant assimilation efficiencies and lack of leaf burn.
  • Offers advantages in promoting reproductive processes and nitrogen conversion efficiencies unlike nitrate-based nitrogen that promotes vegetative growth.
  • It uses nitrogen more efficiently compared to UAN. In a previous trial, replacing 10 gallons of UAN 32% with Checkmate N produced a similar amount of bushels for 50% less cost.

K- Libra – a liquid potassium fertilizer with a potassium concentration of 12%

  • Potassium is plant available at application
  • Cost Effective: Competitive cost compared to other potassium fertilizers
  • Helps to fully support the key functions of plant growth (especially during rapid growth stages)
