Bio-K Opportunities with 10-34-0 and Liquid UAN

Keith Flaniken • June 13, 2019

Much has been promoted and said about NACHURS Bio-K and its unique properties that provide profitable benefits when incorporating this advanced form of potassium into crop fertility programs.

Here are some factual reminders regarding the importance of supporting your potassium management system by incorporating Bio-K into your program.


  • Since plants grow, live, and die by its root systems, it is imperative that a balanced, available, and soluble nutrient management program be incorporated into any fertility program.
  • Potassium provides key components to overall plant health including internal cell pressure, nitrogen use efficiency, stalk strength, drought stress, plant defense mechanisms, photosynthesis, and transport of plant nutrients, among many others.
  • Plants drink their food which means solubility and plant availability is extremely important.
  • Most plants demand high volumes of K late midway through the season, when most of its energy is being funneled into reproduction, just as available K normally begins to run short.
  • Not all potassium is plant available, especially at peak demand. Countless producers share concern that even though soil K ppm levels may be high, they continue to see deficiency symptoms late season, sometimes after pre-applying 300 + pounds of KCl/ac. The plant simply runs out of fuel or available plant potassium when it needs it the most.
  • Science and research has proven time and time again that Bio-K is the most soluble, most plant available, and most compatible form of K there is.
  • All liquid UAN sidedress users should seriously consider adding some Bio-K to that program. It is the perfect opportunity to upgrade UAN with plant available potassium. Providing plant available K as a supplement to soil applied K will greatly enhance the uptake when paired with UAN at sidedress at low ratios (10:1 is most common).
  • Due to Bio-K’s organic acid properties, this source of potassium is providing a premium carbon source for production of primary and secondary metabolites in the plant as well as for the microbes in the soil to feed on. These rhizobacteria will be grateful for the abundance of root exudates and tasty carbon source, which will ultimately lead to plant productivity and yield.
  • Due to its basic science, NACHURS Bio-K product line supports a healthy environment for meaningful conservation management and sustainable agriculture.

As has been stated before, NACHURS Bio-K product lines deliver tremendous value and help achieve sustainable plant growth and development at critical stages, healthy soil biology, and production capabilities. Keep in mind that NACHURS Bio-K products are true plant food solutions and our goal is to feed plants with available, compatible, and soluble plant food when plants need it.

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.

Wayne Becker, District Sales Manager & Agronomy Specialist Blending two NACHURS products (Triple Option® and Balance®) at a 1:1 ratio has proven to jump start soybeans and increase profitability. Many farmers would like to use in-furrow starter fertilizer with their beans but are uncertain of the benefits. When beans are first planted early growth is very important. • It is a race against time between soybeans and weeds, fighting for water, sunlight and nutrients. • The quicker a canopy is established, the less weeds are able to steal resources, which could affect yield potential. Traditional In-furrow fertilization of beans is usually not as easy to visually observe as when it is applied to corn or wheat. However, that does not mean that they are not extremely important. This treatment will provide early season fertility that will help the young crop remain strong and vibrant, enabling them to better deal with stresses like insects, drought or water logging. NACHURS liquid fertilizer has been providing the best in-furrow fertilizer treatments for 75+ years. With NACHURS in-furrow, producers have always been able to safely provide the traditional benefits without decreasing germination because of the fertilizer’s low-salt content and superior availability. New focus on plant and soil health has raised the bar even higher. The NACHURS Bio-K® line of fertilizers is the most available source of K on the market, yet it also promotes both soil and plant health. Because the Bio-K fertilizer is a carbon molecule combined with potassium, applying it in-furrow provides beneficial soil microbes with a food source. This enables microbes to increase nutrient availability – for all types of crops. Legumes use Rhizobia to “fix” their own nitrogen. NACHURS has developed a product specially designed to stimulate early development of these important soil microbes. It is called Balance®. We combine the rhizobia stimulating qualities of Balance with Triple Option which maximizes quantity of other nutrients. The result is improved potential for early season growth and greater profitability of soybeans
