Foliar feeding micronutrients with your glyphosate application

Website Editor • May 23, 2016

We have all seen the benefits of adding a foliar feed application to our growing crops.  Common micronutrients include zinc, iron, boron, copper, molybdenum, and manganese.  Typically adding micronutrients into your spray tank solution with Glyphosate has not been recommended by major manufacturers.  This is, in part, due to the incompatibility with Glyphosate and the form or the salt of the micronutrient being added.   The problem occurs because most micros are positively charged cations and Glyphosate carries a negative charge.  We are all familiar with the term opposites attract, the positively charged cation (micronutrient) will bind with the negatively charged anion (Glyphosate); thus Glyphosate can bind with the micronutrients in our spray tank solution and render Glyphosate ineffective - and the micronutrient as well.   Even the hardness of our ground water used to fill our spray tank can even affect the Glyphosate.  Ground water can contain positively charged cations macros and micro like calcium and iron.  Even though they may be present in very small amounts they could potentially interfere.  Adding ammonium sulfate will usually overcome this antagonism between hard water and Glyphosate by supplying positive charged ammonium for the Glyphosate and offering negatively charged sulfate to the positively charged cations present in ground water.   We can see there is a very delicate balance when adding products into our sprayer.  This is why when we add micronutrients into our Glyphosate application we must make sure they are in a form that will not interfere with Glyphosate and still allow maximum uptake of the nutrient into the crop. NACHURS Finish Line was developed for maximum nutrient uptake to be supplied along with Glyphosate compatibility.  This is possible because NACHURS uses EDTA to neutralize the charge on our copper, manganese, and zinc so that they become more compatible with Glyphosate. Farmers are able to maximize the value of each trip over the field, successfully combining micronutrients and Glyphosate applications. NACHURS Finish Line offers a full micro pack of boron, copper, manganese, and zinc.   NACHURS Finish Line is formulated with EDTA micros, Bio-K (potassium acetate) and fulvic acid which aid in crop development and yield.  -Joe Pflum, Northeast US Sales Agronomist

The effect of foliar fertilization on wheat yield.

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.
