Spring Applied Fertilizers are the Most Profitable Option for Illinois Farmers

Fall-applied nitrogen is not the most profitable nitrogen timing for Illinois farmers according to Precision Conservation Management (PCM) data published in June 2021. Compared to other nitrogen application options, ‘Mostly Preplant’ and ‘Mostly Sidedress’ are both more profitable than fall-applied nitrogen. (See table below.)

 

With fertilizer prices at an all time high, now is the time for farmers to consider reducing overall nitrogen application to MRTN rates and moving to a spring-applied system to maximize profitability and environmental impact.

           

However, considering current nitrogen limitations such as price, sourcing, availability, and others, farmers might be challenged to utilize spring-time application in 2023.

PCM Director Greg Goodwin, commented, “We recognize the difficulty making the transition to a more regular spring application on your operation, but those who have made the switch are seeing great gains not only in their profitability, but also in their environmental impact.”

 

If farmers are faced with no other option than to fall apply, PCM data strongly recommends that farmers apply according to the MRTN and closely follow these guidelines outlined in this University of Illinois’ FarmDoc article:

 

1: No fall application on light or very heavy-textured soil.

2: No application at soil temperatures above 50 degrees Fahrenheit.

3: No fall application in regions without cold winters, including southern Illinois

 

No matter what your plan of action is for applying fertilizer this growing season, the current environmental and economic climate is signaling that farmers plan for spring application for the coming years.

 

PCM data also reports that the most profitable farms in the dataset are never applying over the MRTN and most have a Nitrogen Use Efficiency (NUE) of less than .85 pounds of nitrogen per bushel of corn.

This week, U.S. Secretary of Agriculture Brooke L. Rollins announced the U.S. Department of Agriculture (USDA) Data Modernization Plan to put Farmers First, reduce unnecessary burdens on producers, and improve the timeliness, accuracy, and usefulness of the data that informs agricultural decisions. USDA data informs crop and livestock estimates, risk-management tools, disaster assistance, and critical business decisions made by farmers, ranchers, agribusinesses, researchers, and policymakers. In February 2026, Secretary Rollins issued a Request for Information seeking feedback on the opportunities, challenges, and emerging areas in USDA data. That feedback helped shape the USDA Data Modernization Plan and its four pillars: Modernize the Data Reporting Experience: USDA will expand use of administrative data, improve mobile access to surveys, explore opportunities to use prefilled information where appropriate, and strengthen coordination across the Department. These changes will reduce duplicative requests and limit the amount of time producers spend reporting information. Enhance Acreage and Yield Estimation: USDA will conduct a pilot to evaluate the use of improved satellite imagery, geospatial tools, crop models, and other emerging technologies combined with essential producer-reported information to enhance acreage and yield estimations. USDA will also assess the use of optional field inputs to enhance and ground truth yield estimates and continue advancing yield research through collaboration with agricultural partners and land-grant universities. Integrate Data and Technology Platforms: USDA will modernize its technology infrastructure, expand secure data-sharing capabilities, and evaluate the responsible use of tools such as artificial intelligence and machine learning. Better integrated systems will improve efficiency, reduce duplication, and allow USDA to produce more timely and useful information. Expand Trust and Transparency with Producers: USDA will protect producer privacy, clearly explain why information is requested and how it is used, and create additional opportunities for producers to provide feedback. USDA will also improve communication surrounding reports, methodologies, response rates, and data limitations. USDA will begin implementing actions under the plan immediately and will continue engaging farmers, ranchers, and agricultural stakeholders throughout the process. The Department will evaluate new approaches carefully, protect privacy and confidentiality, and publish clear methodologies and supporting information to maintain the integrity of USDA’s agricultural statistics.
