Forgotten plant nutrients; Don't be left behind!

Website Editor • October 27, 2015

All plants, whether it be corn, soybeans, wheat, cotton, cranberries, canola, or even a household plant such as an ivy or fern, require nutrients for proper growth and development. About 90-95% of plant dry matter is composed of carbon, hydrogen, and/or oxygen. The remaining 5-10% is obtained from the soil and/or from fertilizer supplied by the farmer or homeowner. We all understand the importance of Primary Nutrients (nitrogen, phosphorus, potassium) in achieving production goals that are set each year. However, we often forget the importance of Secondary Nutrients (calcium, magnesium, sulfur) and Micronutrients (boron, copper, iron, manganese, molybdenum, zinc) in the overall process of plant growth and development. Although these nutrients are required in much smaller quantities, they are essential for completion of many physiological cycles and processes within the plant. In many cases, plants cannot fully utilize primary nutrients without adequate supplies of secondary and/or micronutrients supplied at the appropriate time. Below is a listing of functions these nutrients provide within the plant. Nutrient Function in the plant Calcium (Ca) Necessary for the proper functioning of growing points Forms compounds which strengthen cell walls Aids in cell division and elongation Neutralizes organic acids Regulates protein synthesis and slows the aging process Magnesium (Mg) Only mineral component of the chlorophyll molecule Aids in formation of sugars and starches Plays important part in phosphorus translocation Aids in proper functioning of plant enzymes Sulfur (S) Mirrors phosphorus requirements in plants Primary constituent of many amino acids Aids in activation of enzymes and vitamins Needed for chlorophyll formation Used in nitrogen stabilization Nodulation in legume crops Boron (B) Required for cell division Plays important part in calcium translocation Protein synthesis and hormone formation Carbohydrate metabolism Pollen viability Flower formation and fruit set Copper (Cu) Required for chlorophyll production Aids in photosynthesis and enzyme formation Involved in oxidation-reduction reactions Regulates water movement in cells Needed for seed production Iron (Fe) Necessary for the formation of chlorophyll Involved in oxidation process that releases energy from starches Protein formation Aids conversion of nitrate to ammonia in cells Plant respiration Manganese (Mn) Essential for chlorophyll production and photosynthesis Aids in carbohydrate metabolism Oxidation-reduction reactions Enzyme activation Combines with iron, copper, and zinc in hormone balance Molybdenum (Mo) Co-factor in nitrate reductase enzyme Essential for rhizobia in nitrogen fixation process Aids in nitrate utilization Involved in phosphate and iron metabolism Zinc (Zn) Necessary in chlorophyll formation Involved in enzyme activation and production Required in hormone (auxin) and nucleic acid synthesis Aids in uptake and water use efficiency Most of the Secondary and Micronutrients can be provided to plants in a chelated form with the exception of sulfur, boron, and molybdenum.  Chelation allows nutrients to remain available to the plant even if environmental conditions are less than optimal.  There are many forms of chelates that can be used, ranging from EDTA, citric acid, amino acids, and organic acids just to name a few.  In general, EDTA chelates are by far the most stable and are the only form that can be safely added to true, clear NPK solutions (i.e. NACHURS orthophosphates).  NACHURS Micronutrients (9% Zn, 6% Mn, 4.5% Fe, 3% Ca, 2.5% Mg, 7.5% Cu, 10% Boron) offer a wide range of uses under a vast array of growing environments.  Ask for NACHURS Micronutrients today from your local NACHURS dealer so YOU don’t get left behind! - Tommy Roach, Director of Specialty Products & Product Development

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.

'Tis the 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
