Harnessing Residual Soil Nitrogen Following a Dry Season: The Key to Smarter Fertilizer Planning for the Coming Season
Javed Iqbal - NE Extension Nutrient Management and Water Quality Specialist
The 2024 growing season brought drier-than-average conditions to much of Nebraska, impacting crop yields and altering soil nutrient dynamics, especially for rainfed crops. During drought, crop growth is reduced, hence nitrogen movement and uptake are often restricted, leading to higher-than-normal levels of residual soil nitrogen. This can be beneficial for the next growing season as it provides readily available nitrogen for the new crop, but it's important to monitor soil tests to determine the actual amount of residual nitrogen present.
As farmers look toward the 2025 season, this residual nitrogen might offer a valuable opportunity to optimize fertilizer planning, enabling cost reductions, improved crop yields, and enhanced environmental stewardship. Here’s how the farmers in dry-affected areas can effectively harness residual nitrogen for the coming season.
Why Residual Soil Nitrogen Increases After a Dry Year
Dry conditions limit nitrogen uptake in crops, as water is essential for nutrient transport and absorption. Without adequate moisture, nitrogen applied through fertilizers or naturally present in the soil often remains unused. Additionally, drought potentially reduces nitrogen losses from leaching and denitrification, allowing residual nitrogen — particularly nitrate — to accumulate in the soil profile, especially within the root zone.
Harnessing this residual nitrogen can provide a natural nutrient source for crops in the 2025 season, helping reduce the need for additional fertilizers, lowering costs, and preserving soil and water quality.
The Importance of Soil Sampling for Residual Nitrogen Assessment
To accurately gauge residual nitrogen levels, soil sampling is essential. Sampling the soil allows for a comprehensive view of nitrate levels across the soil profile. Here’s how soil sampling can help in optimizing nitrogen application:
Timing of Soil Sampling: After a dry season, soil sampling is ideally conducted in the spring before planting. This timing accounts for any winter nitrogen losses from leaching, ensuring a more accurate picture of available nitrogen. However, if conditions allow and you prefer a preliminary view, fall sampling can be useful — particularly in low-leaching soils.
Depth of Sampling: Sampling to 2 or 3 feet is critical, as nitrate can accumulate in lower soil layers after leaching from the surface. This comprehensive sampling depth provides the data needed to calculate an accurate nitrogen credit.
Using Test Results for Fertilizer Adjustments: Soil test results will reveal the available nitrate concentration, allowing farmers to adjust their nitrogen applications accordingly. For example, if residual nitrate levels are high, farmers can reduce their spring nitrogen applications, minimizing both costs and the potential for nitrate leaching.
Benefits of Using Residual Nitrogen in Fertilizer Planning
Cost Savings: By crediting residual nitrogen, farmers can significantly reduce the amount of nitrogen fertilizer applied. This is particularly valuable after a dry year, when fertilizer prices might fluctuate, and savings can help manage overall production costs.
Environmental Protection: Excessive nitrogen application can lead to nitrate leaching into groundwater, a major environmental concern. By crediting residual nitrogen, farmers apply only what the crop needs, reducing the risk of nitrogen pollution and promoting more sustainable agriculture.
Improved Crop Performance: Matching nitrogen applications to crop needs enhances nutrient uptake, which can improve crop health and yield. By accounting for residual nitrogen, plants receive adequate nitrogen without the stress of nutrient excess or deficiency.
Planning for Spring Nitrogen Needs
While residual nitrogen after a dry year provides a valuable resource, farmers should approach nitrogen management for the new season with flexibility. Use the following guidelines to ensure nitrogen applications meet crop needs without excess:
Conduct Spring Soil Sampling: Even if you sampled in fall, a spring follow-up test is beneficial. This accounts for any nitrogen movement or losses that occurred over winter.
Limit Early-season Applications: Apply only enough nitrogen at planting to meet initial growth needs, then follow up with side-dress applications as the crop grows. This approach minimizes early nitrogen losses and provides nutrients when plants can most efficiently use them.
Use Decision Support Nitrogen Recommendation Tools: The UNL digital nitrogen calculator, variable rate application, and sensor-based technologies can further refine nitrogen applications. These tools help distribute nitrogen only where needed, maximizing efficiency across variable field conditions.
Summary
Following a dry season, residual soil nitrogen becomes a key resource for improving both economic and environmental outcomes in the next growing season. By measuring and crediting residual nitrogen through soil sampling, adjusting fertilizer applications, and adopting strategic nitrogen management practices, farmers can achieve a balanced approach that supports crop productivity and minimizes unnecessary fertilizer use. Harnessing residual nitrogen is a powerful tool for smarter fertilizer planning, ensuring each application maximizes benefit while protecting valuable soil and water resources.

Nebraska Irrigated Acres Recede
NeFB Ag Economic Tidbits
Nebraska can no longer claim to be the nation’s top irrigated state according to data from the USDA 2022 Census of Agriculture. The Census shows Nebraska had 15,122 irrigated farms in 2022 with 7.96 million irrigated acres, a drop in acres of 7% from 2017. The 2017 Census showed 16,122 irrigated farms with 8.59 million acres. The updated figures place Nebraska second to California who has 46,247 irrigated farms and 8.16 million irrigated acres, up from 7.83 million acres in 2017. Arkansas follows Nebraska with 4.75 million acres. The three states together account for 38% of the total irrigated acreage in the nation.
Slightly under 55 million acres in the U.S. were irrigated in 2022, about 18% of total U.S. cropland. That’s the lowest since 1992 and a decrease of roughly 3 million acres from the 2017 Census when irrigated cropland reached a record high 58 million acres. The decline was driven by decreases of 1.8 million acres (14%) in the Mountain region, 0.9 million acres (7%) in the Northern Plains, and 0.7 million acres (15%) in the Southern Plains. The Mountain region has the most irrigated acreage with 11.4 million acres in 2022.
2024 Silver Eagle Award to Honor Steve Nelson
Nebraska Farm Bureau (NEFB) has selected Steve Nelson of Axtell as the 2024 recipient of its highest honor, the Silver Eagle Award. The award will be presented to Nelson on Dec. 10 at the 2024 Nebraska Farm Bureau Annual Meeting and Convention in Kearney.
“Nelson has devoted his entire life to agriculture, showcasing unwavering commitment and service to the agricultural community in Nebraska. He has served as a passionate advocate and a representative striving to enhance the well-being of all farm and ranch families across the state,” said Mark McHargue, NEFB president.
Nelson started his farming career in the early 1970s while still a high school student. Today, he and his wife, Elma, cultivate corn, hybrid seed corn, and soybeans on their family farm near Axtell, which has been passed down through six generations.
Nelson began his Farm Bureau career after graduating from the University of Nebraska–Lincoln, serving in many roles on the Kearney/Franklin County Farm Bureau Board. Steve was elected to the state Board of Directors in 1997, representing the South Central District. He was elected to the position of first vice president in 2002 before being elected as Nebraska Farm Bureau president in 2011.
Nelson was elected to the American Farm Bureau Federation (AFBF) Board of Directors in 2014. He has served on the AFBF Trade Advisory and Governance committees and served as chairman of the Feed Grains Committee, the Water Quality Task Force, the Information and Technology Committee, and the Making American Agriculture Productive and Profitable Committee. He has accompanied governors and AFBF on trade missions to China, Costa Rica, Cuba, England, France, Mexico, Panama, Peru, and Taiwan.
“During his service to Nebraska Farm Bureau, Steve moved the organization forward by prioritizing the expansion of agricultural trade and the exploration of new markets for agricultural commodities. Additionally, he emphasized a key focus on halting high-profile initiatives that could negatively impact the state. Steve also played a pivotal role in positioning Farm Bureau to be a leading voice in elevating awareness of Nebraska’s outrageously high property taxes to headline status and pushing for legislative action to address the problem,” said McHargue
In addition to advocacy work, Nelson helped advance and modernize the Nebraska Farm Bureau organization. Among those efforts was the establishment of the Nebraska Farm Bureau Foundation to initiate programming to bridge a growing disconnect between agriculture and urban Nebraska. Nelson also supported expanded resources to help Nebraska Farm Bureau’s 86 County Farm Bureaus that make up the organization’s membership, including investment in programs geared toward leadership development and youth programs to grow agriculture’s base of leaders and influencers.
When Nelson retired as Nebraska Farm Bureau’s president in 2020, the organization honored him by sponsoring the Steve Nelson Yeutter Institute International Trade Internship Award, which provides students at the University of Nebraska–Lincoln the opportunity to work in the heart of the trade policy community in Washington, D.C., at the Washington International Trade Association (WITA).
“Students who participate in the Washington, D.C., program work under the mentorship of WITA’s executive director and managing director and gain valuable exposure to and experience with trade policy issues. Following completion of the internship, the intern uses skills gained to plan a Yeutter Institute educational event for students and the public on an agricultural trade policy issue important to Nebraska,” said McHargue.
Nelson is a member of numerous state and national agricultural organizations. He is a lifelong member of Bethany Lutheran Church near Axtell. Steve and Elma became members of the Hastings-area chapter of Compassionate Friends after their daughter, Sarah, passed away unexpectedly following a 2006 surgery. Steve and Elma have two other children; Scott (Amy) and Stacy (Bobby), and five grandchildren; Sam, Luke, Britta, Bo and Natalie.
“Nebraska Farm Bureau is stronger because of Steve’s vision for agriculture’s future,” McHargue said. “We congratulate Steve. He is extremely worthy of Nebraska Farm Bureau’s highest honor, the Silver Eagle Award.”

Webinar Series Unlocks Potential of Perennial Groundcovers in Corn and Corn/Soybean Production Systems
A five-week lunch-and-learn webinar series starting in January will explore the innovative use of perennial groundcovers in corn and corn/soybean production systems as a cover crop. This series, sponsored by Iowa State University and RegenPCG, will be held on consecutive Tuesdays (Jan. 14, 21, 28 and Feb. 4 and 11, 2025) from 12-1 p.m. CST.
Perennial groundcover in a corn field.As sustainable agriculture continues to grow in importance, perennial groundcovers used within corn and soybean production systems offer a promising solution, noted Daniel Andersen, associate professor in agriculture and biosystems engineering at Iowa State University.
“Perennial ground covers are plants that are established and maintained within the row crop production system without needing to be replanted annually. They can help suppress weeds, provide habitat for beneficial insects and offer environmental benefits for erosion and nitrogen control,” Andersen said. “However, they increase complexity in our cropping system so require careful management to ensure competitive yields with traditional methods of crop production.”
This webinar series will focus on providing information on what perennial groundcover agriculture is, the potential benefits it offers, insight into how to effectively manage these systems, and work that is being undertaken to make them more robust for widespread adoption and implementation. The presentations are tailored for farmers, crop advisors, technical service providers, government agencies (NRCS/DNR) and other agricultural scientists eager to understand the possibilities and challenges of integrating perennial groundcovers into their row crop agriculture.

CHS reports fiscal year 2024 net income of $1.1 billion
CHS Inc., the nation's leading agribusiness cooperative, today reported net income of $1.1 billion for the fiscal year ended Aug. 31, 2024, compared to $1.9 billion for fiscal year 2023.
Key highlights for fiscal year 2024 financial results include:
Consolidated revenues of $39.3 billion for fiscal year 2024 compared to $45.6 billion for fiscal year 2023, a change attributed to lower commodity prices.
Financial performance remained solid across segments, although down from historically strong results, including record earnings in the prior year.
Evolving market conditions, including less favorable refining margins, led to weaker Energy segment results compared to fiscal year 2023.
Ag segment earnings declined from the prior year due to softening oilseed crush margins and global conditions that drove down margins for U.S. grain exports.
Equity method investments continued to perform well, with our CF Nitrogen investment being the largest contributor.
“Our earnings for fiscal year 2024 were solid, thanks to the support of our owners and customers around the world. CHS intends to return $600 million in cash patronage and equity redemptions to our farmer-owners and member cooperatives in fiscal year 2025, as we continue to share profits with those that work with us to empower agriculture and help feed people around the globe,” said Jay Debertin, president and CEO.
“We remain committed to strategically investing in strengthening our grain, agronomy and energy supply chains to provide end-to-end value and enhance market access for U.S. growers,” said Debertin. “As our industry navigates a challenging market environment, CHS is focused on efficiency and managing costs while still enhancing customer experience and driving growth on behalf of our owners."
Fiscal Year 2024 Business Segment Results
Energy
Pretax earnings of $429.1 million in fiscal year 2024 represent a $646.4 million decrease versus the prior year and reflect:
A substantial reduction in refined fuels earnings due to the negative impact of industry trends on refining margins and less favorable pricing of heavy Canadian crude oil
Reduced costs for renewable energy credits, which partially offset the impact of unfavorable market conditions
Ag
Pretax earnings of $342.7 million represent a $69.1 million decrease versus the prior year and reflect:
Weaker crush margins due to an increased global supply of canola and soybean meal and oil, partially offset by operational and logistical efficiencies at CHS oilseed crush plants
Improved margins and higher volumes for wholesale and retail agronomy products
Compressed margins in the grain and oilseed product category due to global market conditions
Nitrogen Production
Pretax earnings of $151.2 million represent a $109.5 million decrease versus the prior year. The reduction in equity method income is due to lower global prices of urea and UAN, produced and sold by CF Nitrogen, our joint venture with CF Industries, which were partly offset by decreased natural gas costs.
Corporate and Other
Pretax earnings of $174.8 million represent a $84.9 million decrease versus the prior year and reflect less favorable market conditions for oil-based food products produced by the Ventura Foods joint venture.

New Report Highlights Impact of Glyphosate Loss on Farm Bill Programs
The Directions Group, formerly Aimpoint Research, today announced the release of a new report, "Farm Bill Programs and the Role of Crop Protection Tools," which identifies significant impacts on the farm bill and federal agricultural policy if U.S. farmers lost access to glyphosate, the most commonly used herbicide. The commodities, conservation, nutrition, and crop insurance titles are among the key farm bill provisions potentially affected. Using open-source research and economic modeling, the analysis shows that disruptions to glyphosate availability would have costly consequences for farmers, consumers, and the environment.
"Conflicting state and federal pesticide labeling requirements could create a challenging regulatory landscape for crop protection products," said Mark Purdy, Executive Vice President of Agri-Food at The Directions Group. "That's why this research is critical. It shows that losing access to glyphosate could create far-reaching consequences for the farm bill."
Key takeaways from the report include:
Food inflation could surge by 2.4 times based on 2025 forecasts.
Farmers could lose $2.89 billion in annual net farm income.
Nutrition program outlays for programs like the Supplemental Nutrition Assistance Program (SNAP) could increase by $7.1 billion over the life of a 2025-2029 Farm Bill.
Crop insurance costs may increase by $2.946 billion over the life of a 2025-2029 Farm Bill.
CO2 emissions would likely rise by 33.72 million additional tons every year.
The 2018 Farm Bill's $632 million investment in cover cropping would be undermined, reversing two decades of conservation gains in carbon capture, sediment loss, and nutrient runoff reduction.
"The increase in production costs would ripple through the economy, creating substantial challenges for both farmers and policymakers," said Dave Juday, Executive Advisor to The Directions Group and lead economist for the report. "It could undermine the farm bill and put pressure on policymakers to slash budgets for key programs in response to rising costs."
