Specialists Discuss Planting, Fertility, and Pest Protection for Stronger Corn Yields

North Dakota corn growers are preparing for spring planting as warmer soil temperatures gradually improve field conditions across the state. Extension specialists encourage farmers to focus on proper planning, fertility management, and pest control practices to improve corn production and protect farm profitability during the 2026 growing season.

Jeff Stachler, NDSU Extension Cropping Systems Specialist at the Carrington Research Extension Center, along with Brady Goettl, NDSU Extension Soil Science Specialist, emphasized that selecting the correct corn hybrid remains one of the most important decisions for successful production. Hybrid performance, crop rotation, and uniform plant emergence all contribute to better yields and healthier crops throughout the season.

Farmers are also being advised to inspect planting equipment before fieldwork begins. Proper planter operation can improve seed spacing and planting accuracy, helping crops emerge evenly. Soil temperature and moisture conditions are important as well. Specialists noted that corn emergence improves when average soil temperatures at four inches approach 65° Fahrenheit.

Planting depth remains another key management factor. Experts generally recommend planting corn about two inches deep to encourage healthy root growth and consistent emergence. Seeding rates may vary across different regions of North Dakota depending on rainfall levels, soil conditions, and drought concerns.

Fertilizer planning continues to be a major focus because of high fertilizer costs. Growers are encouraged to complete soil testing and manage nutrients carefully rather than reducing applications without field information. Residual nitrogen from the previous season may also help reduce fertilizer requirements in some areas during 2026. Maintaining balanced nutrient levels, including nitrogen, phosphorus, and potassium, is important for healthy crop growth.

Pest management is also receiving increased attention following weed, insect, and disease problems reported during 2025. Herbicide-resistant waterhemp, tar spot disease, and northern corn rootworm populations have created additional challenges for growers in several counties.

Specialists encourage farmers to scout fields regularly during the season to identify pest or disease concerns early and make timely management decisions that help protect crop yields.

Turning Plant Defense Into a Management Strategy

Understanding how a plant responds to stress is one thing.

Using that knowledge to make better management decisions is another.

Systemic acquired resistance, or SAR, is the plant's more direct defense response. When stress or infection occurs, the plant begins signaling throughout its system and preparing defensive compounds.

But if we know that response exists, can we help prepare the plant before the stress arrives?

The answer starts with understanding what triggers the response and what the plant needs to carry it out.

The Trigger and the Fuel

Salicylic acid plays an important role in triggering the SAR pathway.

Think of it as turning the truck on.

The engine may be running, but it still needs fuel to do the work.

In this case, manganese plays an important role in supporting the enzyme systems involved in the plant's defensive response.

This makes manganese status an important part of the conversation. Whether a producer is using tissue testing, sap analysis, or simply scouting for visible deficiency symptoms, the goal is to make sure the plant has adequate manganese available.

Manganese is required in relatively small amounts, but that does not make its role small.

If the plant receives a signal to defend itself but lacks the nutrition needed to support that response, it may struggle to carry out the process efficiently.

The trigger matters.

The fuel matters too.

Prepare Before the Stress Arrives

The best time to think about stress management is before the plant is overwhelmed.

Once a crop is already struggling, management can quickly turn into a game of catch-up.

This is similar to nitrogen management. Once a plant becomes severely deficient, correcting the problem does not necessarily erase the time and yield potential already lost.

Plant defense can work the same way.

Low-rate, targeted approaches designed to support the SAR pathway may fit best ahead of an expected stress event rather than after significant damage has already occurred.

That requires producers to think about predictable stress.

We may not know exactly what the weather will do tomorrow, but we generally know summer heat is coming. We know certain field conditions increase disease pressure. We know a herbicide application can temporarily stress a crop as the plant processes the chemistry.

Even a properly timed and labeled herbicide application can create a temporary response in the plant.

That does not mean the herbicide is bad.

Weeds can create significantly more yield loss than the temporary stress caused by controlling them.

The question is not whether we should eliminate every stressor.

The question is whether we can better prepare the plant to manage necessary and predictable stress.

Not All Stress Is Bad

Stress is a normal part of plant growth.

A perfectly stress-free environment does not exist in the field.

In fact, some stress is necessary for normal plant development. A plant responds to wind, temperature, moisture, sunlight, and countless other environmental signals throughout the season.

The environment is stress.

The plant's job is to manage it.

Problems begin when the stress load becomes greater than the plant's ability to respond.

Extreme heat, drought, high salt concentrations, disease pressure, and even certain management practices can add to that load.

This is where understanding SAR becomes useful.

Instead of waiting until the plant is visibly struggling, producers can begin identifying periods when stress is likely and make management decisions around those windows.

ISR Starts With the Soil

While SAR is a more direct defense response, induced systemic resistance, or ISR, brings the conversation back to soil health.

The longevity of a farm is closely connected to the health of its soil.

Carbon plays a major role because it supports biological life within the soil. Bacteria, fungi, and other organisms interact with plant roots and influence how the plant grows, accesses nutrients, and prepares for stress.

This is why soil health cannot be reduced to one product or one application.

It is a system.

Keeping living plants in the field longer can support biological activity. Cover crops may fit some operations. Better water management can improve soil conditions.
