The Benefits of Boron

Finding the right balance for stronger growth

Boron has gained considerable attention in recent years for corn and soybean fertilization with current research pointing toward an early season need for both crops. While boron is key for seed production, its role in the development of root tips is where researchers in the US are seeing the biggest benefit for this lesser-known nutrient.

One of the key considerations for using boron effectively is the fine line between deficiency and toxicity. The crop need for boron is very small, and the tolerance range is very narrow, which means too much of the nutrient in the root zone can cause boron toxicity.


Minimize risk with better solutions

Boron shouldn’t go in a starter, unless you are sure you can apply a low enough quantity to avoid toxicity while maintaining a high enough level to be effective. For most growers, using boron in a starter isn’t worth the risk — especially since there are safer ways to deliver it to the crop.

Granular B: using granular boron can work, but with very low application rates, achieving effective distribution is a challenge.

Procote B: with this method, it is recommended that you impregnate your broadcast fertilizer with boron and lightly work it in.

Nitro-B: for a more sophisticated and cost-effective way to get the micro-nutrient to your crop, use liquid boron with pre-emerge chem or in a side-dress application.
