There Is Nothing Magic about Nutrient Efficiency

Website Editor • June 7, 2016

High efficiency fertilizer applications are often misunderstood by those who could potentially benefit from them.  Farmers are often told that “one product may be 5 or 6 times more efficient than standard fertilizer” or “if you apply fertilizer in a different manner you will increase efficiency by 50%”.  These statements may or may not be true, but they don’t tell the whole story and they often lead to misunderstanding and mistrust between the farmer and the retailer. Fertilizer efficiency can be described as how effective a fertilizer application is at being absorbed by the growing crop.  We need to understand that the environment in which these fertilizers are being applied dictates the actual “nutrient efficiency”.  The specific crop environment works against fertilizer applications by leaching, binding, and volatilizing fertilizer. The environment varies greatly between fields, regions, and seasons.  It is affected by weather, soils, crop variety, compaction, and a host of other factors. There are two factors that affect the efficiency of a fertilizer application.  Managing the way we apply fertilizer is one - careful selection of the source of fertilizer is the other.   Considerations for applying fertilizer efficiently: Placing some fertilizers in a band will minimize reactions with the soil; Foliar feeding crops may move a much higher percentage of nutrients into the plant than soil applications; Adding chemistry that stabilizes fertilizer in the environment will help reduce nutrient loss through volatilization or binding in soils; Applying nutrients when the plant needs them reduces time the fertilizer is exposed to the environment which increases plant availability.   Considerations for selection of fertilizer source for improved efficiency: All nutrients must be soluble to move into a plant.  Any portion of the fertilizer which is not in liquid suspension will not be taken into the growing crop. Nutrients must have minimal burn potential.  Salt content of a fertilizer can burn roots or foliage.  When growing tissue is negatively affected by salt it is unable to absorb the potential fertilizer. Nutrient form may reduce loss or increase plant uptake.  Understanding chemistry is difficult.  We understand differences between urea, nitrate, and anhydrous ammonia, but other nutrients are much less understood; orthophosphates are available for immediate uptake and potassium sources must be paired with another element such as chloride, sulfate, etc.    Ultimately, if nutrient input does not equal crop removal we are mining nutrients from the soil.  One day this will require that the mined nutrients must be replace to maintain productivity.  Therefore maintaining an acceptable level of soil fertility and then utilizing fertilizer sources and application methods that move a higher percentage of nutrients into the plant is the most logical approach to improve productivity, profit, and sustainability.  NACHURS leads the industry with development of core fertility products which improve crop nutrient uptake.  NACHURS' next generation of products (Rhyzo-Link, Bio-K, NACHURS Finish Line, and Aqua-Tech) improve upon these industry leading standards!-Wayne Becker, Southern US Sales Agronomist

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
