Balanced plant nutrition: more than just optimum growth

Wayne Becker, Southern RSM • September 17, 2018

Balanced fertilizer applications may reduce the need for chemical disease control in some cases. Scientists who breed crops are continually attempting to develop new varieties that are resistant to pests and disease. The big challenge is that pests and disease continually adapt to their environment, which inevitably cause resistant varieties to fail and become susceptible to pests and disease.

Even though genetic resistance is the primary path to pest avoidance, environmental factors also play a huge role. Plant nutritional status is one of these environmental factors. Usually a balanced nutrient supply ensures optimal plant growth and also pest resistance.

Balanced plant nutrition is key to using plant nutrition as a tool to minimize crop pests. Often over application of one nutrient may induce deficiency of another, especially potassium, which could lead to increased disease occurrence. This is especially true when it comes to nitrogen. Often farmers mistakenly over-apply nitrogen in an attempt to increase plant growth. While maintaining adequate N is essential for healthy crops, excessive N can promote many diseases and insect pests.

Potassium is one of the most notable nutrients involved in maintaining crop health. K deficiency increases susceptibility of host plant to blight, rusts, and even possibly Fusarium. Potassium deficiency reduces the synthesis of proteins, starch and cellulose. However, there is no need for K levels to be increased above optimum levels.

Phosphorus is also important. Even though it is not one of the primary nutrients known for decreasing disease, it has been known to suppress take-all in wheat, and foliar applications may be effective against some airborne pathogens.

Additionally, secondary and micronutrients also play a role in increasing plant avoidance of pests and diseases. Ensuring sufficient amounts of Ca, B, Cu, Zn and especially K enables plant cells to ward off pathogenic invaders because they create plant cells that are less penetrable. Also, N, P, Cu, and Mn have been noted to decrease severity and incidences of Soil-Born Fungal and Bacterial disease.

Nutrient supply changes the resistance of plants to pathogens and pests by altering growth and tissue composition. Effectively timing and placing quality sources of nutrients may lead to benefits for farmers that go well beyond maximizing growth and development of crops.

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
