AgroInsights- Spring Time

May 4, 2023

Spring is here, and now it's time to start planting.


Chad Smith, Sales Agronomist US North


           Spring is finally in the air; we have had a slow start to the spring season in the northern region with a record amount of snow and cool spring temps to melt it away. I’m beginning to see equipment working in the fields and planters dropping the first seeds of the season. The cool, wet weather might hang around longer than one would like, creating a perfect storm for nutrient deficiencies to be visible in corn. While these cosmetic issues can be unsettling, they won’t last forever as warmer weather becomes the norm. As the soil warms up, it will increase microbial activity and nutrient availability for the corn crop, and the temporary nutrient deficiency symptoms will diminish as the corn crop recovers. 


           As split-applied nitrogen has become a standard practice in the north region, we can help corn recover faster by placing three essential macronutrients beside the row with a side-dress application. Nitrogen, Potassium, and Sulfur are needed in large quantities when the crop is in the V6-V12 grow stage.


           NACHURS K-flex® is a premium Bio-K® additive with the perfect potassium and sulfur blend. Bio-K is a premium source of potassium fertilizer combined with a natural plant metabolite, the most effective and efficient source of potassium. What makes Bio-K unique is the origination of its organic-based carrier (anion), the acetate molecule. Acetate is a natural plant metabolite. It is more rapidly and readily taken up by plants, increasing potassium use efficiency and higher productivity. Adding K-flex to UAN improves the nitrogen efficiency of UAN and increases nutrient uptake by the plant. K-flex is more compatible with UAN when comparing it to potassium thiosulfate or sulfite.


           Who doesn’t want to be more efficient with their UAN side-dress application? By adding K-flex to your UAN side-dress program, you can be assured you are providing the most effective and efficient source of potassium, along with nitrogen and sulfur, to maximize your yield this season.

Post-Harvest Reflections

December 12, 2024
We are at the point in the year where things are slowing down around the farm and it is time to reflect on the season to remind ourselves what we learned. Over the last couple of weeks, the District Sales Managers and I have spent some time reflecting on what worked well in the field and the challenges we faced too. Here are the top 5 things we learned from 2024 growing season: #1 Split applying Nitrogen and Sulfur is a practice that should be embraced on a yearly basis when growing corn. Do you remember how the planting season started and what happened in the first 60 days after the planters started rolling? Our field conditions started out dry with some areas of the corn belt showing up on the drought map. Then mother nature blessed us with rain that never stopped in some areas making it difficult to finish planting. Growers that had split applied their Nitrogen and Sulfur were able to avoid nutrient loss from the rain but also apply the nutrients when the crop needed it most. In the end yield was better on split applied nitrogen fields compared to fields that had all the N applied in the fall or spring before planting. #2 For the past 2 seasons in the North region, we have seen the benefits of adding NACHURS Humi-Flex FA to the in-furrow starter fertilizer. NACHURS Humi-Flex FA is our fulvic acid and it is becoming a valuable component in our starter fertilizer for many reasons. We are using it to chelate the nutrients in the starter fertilizer especially phosphorus. Humi-Flex FA also buffers the soil pH to neutral in that nutrient band keeping nutrients available in fields that have less then optimal pH for crop growth. Finally, we use Humi-Flex FA to create a healthy soil microbiome that leads to more root mass and nutrient uptake. #3 Nutrient uptake charts for corn and soybeans have been a great tool for our team to help our customers visualize the crops nutrient needs based on timing during the growing season.
