The platform will be available this year as the core tool under the new Truterra brand. The full suite of the Truterra offering aims to advance the agricultural industry's ability to enable conservation at scale across a variety of crops, commodities and commitments.
"Truterra holds tremendous potential to harness stewardship to drive value by providing data-driven insights from farm-to-fork," said Matt Carstens, senior vice president of Land O'Lakes SUSTAIN. "Using the Truterra Insights Engine, farmers and food companies will have the ability to establish and report clear metrics, create customized stewardship strategies that meet farmers where they are in their sustainability journey, and use a common language for on-farm stewardship that holds meaning and value. It's a major step forward in supporting food system sustainability that starts on the farm."
One of the biggest challenges in understanding and enhancing the sustainability of our food system remains a lack of comprehensive tools that can quantify economic and environmental benefits for farmers to identify farm management options. The Truterra Insights Engine, along with other technology services and tools under the new Truterra suite of offerings, will help to fill this need by providing tangible conservation options and benefits customized to every business.
The Truterra Insights Engine leverages agronomic expertise and technical capabilities from a variety of contributors to enhance the value of stewardship across the supply chain. Such collaborations include USDA's Natural Resources Conservation Service and integration of the sustainability metrics of Field to Market's Fieldprint Platform. The Insights Engine even ties into major private-sector commitments such as Walmart's Project Gigaton.
For farmers and agricultural retailers, the Truterra Insights Engine will utilize soil, weather, economic, and farm management data to create customized reports showcasing the potential impacts of various stewardship practices – providing field-by-field insights, tracking against both economic performance and conservation practices. Together, the economic and environmental results will facilitate the long-term productivity and success of our farmers and food system.
A key differentiator for this platform from other data tools is its design to be of value for farmers first and foremost. It was created by a farmer-owned cooperative, to be used by farmers, agricultural retailers, and agricultural experts to improve on-farm economic and natural resource stewardship. The benefits of the platform span the food value chain, but it was built to start with the farmer and deliver value back to the farm.
Importantly, the Truterra Insights Engine will measure and track stewardship progress over time. In addition to helping farmers make the right choices for their business, these expanded metrics will help food companies achieve their sustainability goals – leading the industry toward a more sustainable food system.

Matt Helmers, a professor in the Department of Agricultural and Biosystems Engineering and extension agricultural engineer, began his duties on Sept. 1. Helmers succeeds Hongwei Xin, assistant dean of research for the College of Agriculture and Life Sciences and a professor of agricultural and biosystems engineering, who served as interim director since 2017.
Helmers joined Iowa State in 2003. He serves as the agricultural and biosystems engineering department’s associate chair for research and extension and holds the title of Dean’s Professor in the College of Agriculture and Life Sciences.
“Dr. Helmers is well-known among Iowa farmers and water quality researchers as an exceptional scientist and a trusted source of information about nutrient management,” said Joe Colletti, interim endowed dean of the College of Agriculture and Life Sciences. “His leadership of the Iowa Nutrient Research Center is a significant new chapter in addressing the goals set forth in the Iowa Nutrient Reduction Strategy.”
Helmers was part of the scientific team that worked on the strategy’s Nonpoint Source Science Assessment, serving as its nitrogen team chair. He served on the Environmental Protection Agency’s Science Advisory Board Agricultural Science Committee from 2016 to 2018.
The Iowa Nutrient Research Center has committed $8.7 million to 76 research projects since it was created in 2013 by the Iowa Board of Regents in response to legislation passed by the Iowa Legislature. The center funds research by scientists at Iowa State, the University of Iowa and the University of Northern Iowa to address nitrogen and phosphorus nutrient losses to surface waters. They pursue science-based approaches to areas that include evaluating the performance of current and emerging nutrient management practices and providing recommendations on implementing the practices and developing new practices.
Helmers is involved in research and extension and outreach activities in the areas of water management and water quality. One focus area is subsurface drainage and the impacts of agricultural management on nutrient export from subsurface drained lands. Another focus is surface runoff from agricultural areas, including the strategic placement and design of buffer systems focusing on how buffer systems can be used to minimize environmental impacts.
He is faculty adviser to the Iowa Learning Farms, a partnership of farmers, non-farmers, urban residents, educators, agencies and conservationists to promote a renewed commitment to a Culture of Conservation. This year he was presented the Outstanding Achievement in Extension Award by the Iowa State College of Agricultural and Life Sciences and received its Dean Lee R. Kolmer Award for Excellence in Applied Research in 2017.
Helmers earned a bachelor’s degree in civil engineering from Iowa State in 1995; a master’s degree in civil engineering in 1997 from Virginia Polytechnic Institute and State University; and a doctorate in agricultural and biological systems engineering from the University of Nebraska-Lincoln in 2003.
Pen-pack manure contains the macro nutrients nitrogen, phosphorus, and potash along with a host of micronutrients.
The nutrient content can vary depending on species, feed products fed, and the amounts of straw or sawdust used for bedding.
The farm's manure handling and storage practices also impact the nutrient content of manure. Manure stored under roof will usually maintain a higher nutrient value than manure exposed to rainfall. | READ MORE
The Iowa Administrative Code only allows a maximum of 100 pounds N per acre manure application on ground to be planted to soybean. However, it does allow fields that had liquid manure applied at rates intended for growing corn to be switched to soybean on or after June 1 with no penalty of over-application of manure nitrogen. Thus if a field planned for corn has not been planted and will be switched to soybean, this can be done. Producers should document the changes in crop rotation, application methods and other changes in their annual manure management plans.
Given it has been a wet spring in some areas, nutrient management and specifically, nitrogen loss may be top of mind. Livestock producers with Iowa Department of Natural Resources [DNR] manure management plans are reminded if they have already applied the maximum nitrogen rate to the field, they can’t apply additional sources of nitrogen unless the need is confirmed by the use of a Late Spring Nitrate Test. This test measures nitrate-N concentration at the 0 to 12-inch depth.
Results can be interpreted by the ISU Extension and Outreach publication “Use of the Late-Spring Soil Nitrate Test in Iowa Corn Production” (CROP 3140), which considers both the original fertilizer source and the amount of rain that occurred in May (excessive is more than five inches in May). When adding extra nitrogen, be sure to document soil sample results and reference the publication to interpret the test results in management plans.
While fall provided favorable application conditions, and periods in March were favorable, producers should plan ahead if not as much manure as normal is applied in the spring. Having a plan in place will help prevent potential issues from turning into problems. Keep an eye on storage, and have a plan for needed action.
Bryce Davis, Wright County’s economic development director, says the plant will be located in a rural area about ten miles from Clarion and it’ll take in up to 150,000 tons of chicken waste per year from several area poultry plants. READ MORE
- Inspect equipment. Make sure everything is functioning properly. To avoid leaks or spills, replace or repair anything that needs fixed.
- Get your manure sampled and analyzed, or find your most recent manure analysis. This will give you an accurate idea of how many nutrients are available to you.
- Plan applications for each field. Calculate your application rates using the nutrient needs of your upcoming crop (based on the University of Minnesota recommendations) and your manure nutrient analysis. Subtract out any nutrient credits from manure applied in the past 3 years or from legumes grown in the past year.
- Determine any setbacks needed in fields. This includes streams, ditches, lakes, tile inlets and sinkholes. Also mark locations of sensitive features to avoid.
- Put together an Emergency Action Plan. Make a list of emergency contacts in case of a leak or spill and think of ways that you could possibly contain a spill so that you can have the appropriate tools on hand.
- Monitor the weather. Avoid applying immediately before a predicted rainfall.
- Avoid wet or frozen fields. Manure can very easily run off of a frozen field, especially in spring rains. On fields that are wet, adding manure (which has liquid in it) will only increase the likelihood of runoff or the start of tile flow. You are also more likely to cause soil compaction in wet conditions.
- Apply manure according to calculated rates. Do not overapply! Nutrients are less likely to be lost to our waterways when applied at appropriate rates.
- Monitor equipment for leaks. Have equipment handy for stopping leaks and for cleanup. Know the numbers you need to call if there is a spill.
- Keep records. Always note the field location, manure source and amount applied. Keep records on file for at least three years.
Greenhouse gases contribute to the warming of our atmosphere. Carbon dioxide gets the most attention because so much is released as we burn fossil fuels. Nitrous oxide (yes, the “laughing gas” the dentist may give you) is also a powerful greenhouse gas. There isn’t nearly as much of it in our atmosphere as carbon dioxide: it makes up only about five percent of the greenhouse gases, compared to 82 percent for carbon dioxide. However, it is a much more potent greenhouse gas, with a global warming potential nearly 300 times greater than carbon dioxide.
About 40 percent of all nitrous oxide emissions come from human activities, and agriculture is by far the greatest source. About 90 percent of that contribution comes from soil and nutrient management practices like tilling and fertilizing. This means that changes in these practices have great potential to reduce nitrous oxide emissions from agriculture. But there is also the potential to make them worse.
That’s where manure injection comes into the story. Animal manure has been used as a fertilizer for thousands of years. It is an excellent source of nutrients for plants and helps build good soil. Manure slowly releases nitrogen, one of the primary elements that help plants grow. Because of this slow release, it does not have to be applied as often as commercial fertilizer.
Traditionally, manure has been spread, or broadcast, onto the fields. However, with changing weather patterns some areas have had heavier rains and more flooding. Many farmers are taking steps to avoid manure runoff that can affect the quality of lakes and streams nearby. One such step is manure injection, a relatively new way of applying manure. It helps keep the manure on the crops and on the fields. Manure injectors insert narrow troughs of liquid manure six to eight inches deep into the soil.
“Unfortunately, at that depth conditions are just right for producing nitrous oxide,” said Adair.
The soils are often wet and there is little oxygen. This leads microbes in the soil to change the way they convert organic matter into energy. This alternative process changes nitrogen into nitrous oxide as a byproduct.
Adair and her colleagues have been studying the potential of tillage and manure application methods to reduce nitrous oxide emissions. They are comparing conventional tilling versus no-till systems, and broadcast versus manure injection.
Through several farm and laboratory experiments, they have found the tillage method has little impact on nitrous oxide emissions. However, manure injection significantly increases nitrous oxide emissions compared to the broadcast method. This is especially true soon after injection. Warming soil in the spring and more winter thaw/freeze cycles in winters also seem to increase emissions. And when warmer winters are combined with manure injection, this multiplies the effect, leading to even more nitrous oxide emissions.
Adair says ongoing research may show the cause of winter and spring emissions and whether there are steps that can reduce them. Perhaps cover crops grown between main-crop seasons will be able to reduce wintertime nitrous oxide emissions. And perhaps the timing of manure injection is important.
“Injecting during dry periods seem to reduce emissions, and it may be that fall injection results in smaller emission pulses, but we don’t have enough evidence of the latter yet,” Adair explains. “Our work continues so we can find better answers for growers, and protect the environment.”
Adair presented this research at the October Annual Meeting of the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America in Tampa, FL.
Manure application in winter should not ever be part of a manure management plan. Rather, it should be part of a contingency plan, because we all know that weather happens. Frequent rain and a late corn harvest are taxing manure storage capacities on many farms. Contingency plans are essential for manure that must be applied in less than ideal conditions. A forage or wheat field can be an ideal site for contingency plan manure application, because compaction should not be an issue, and the soil cover would help prevent nutrient runoff and erosion. Forage or wheat fields are ideal for those reasons. However, winterkill becomes a much greater risk, especially with application of liquid manure. Why? Beside the common risks – which include compaction from wheel traffic and crown damage – manure contains salts!
Salinization, the concentration of salt in the root zone, is not an issue in Ontario. Ample precipitation and drainage leaches the salts through the soil profile. However, when the soil is frozen, infiltration can’t occur. Salts in manure can then turn deadly. High sodium also has a negative effect on soil structure; making the soil more susceptible to crusting, and further decreasing the capacity for infiltration.
Livestock manure contains many salts, including ammonium, calcium, magnesium, potassium and sodium. When accrued, they can be significant. Salt content varies from farm to farm based on livestock species, diet formulation and even the salt in the drinking water. Many manure analyses report “Total Salts” or electrical conductivity (EC) to reflect the accumulated salts. A typical hog manure (as applied basis) can have about 20 mS/cm (milliSemens/cm) or about 125 lbs of total salts per 1,000 gallons. Dairy manure average is 14 mS/cm or about 90 lbs/1000 gallons. Sodium and magnesium chloride have a working temperatures to about -15° C; potassium chloride to -4° C, while calcium chloride can work to about -23° C.
When manure is applied on frozen or snow-covered soils, the salts melt the snow and ice at the soil surface. The layer below may still be frozen, preventing infiltration. The melted, saturated layer is high in salts, toxic to roots, and more prone to erosion and runoff, and more susceptible to frost heaving. All these risks are increased where manure with high EC or total salt contents has been applied.
When contingency plan applications become necessary during the winter season, options include:
- Late summer application to forage crops after the final cut or at the beginning of the critical harvest period,
- Temporary storage at a neighbouring storage that has extra capacity,
- Application to forage fields or cover crops that will be tilled or killed,
- Application to the most level harvested fields, preferably with residue still present, furthest away from surface water, where application does not occur through water runs or “flow paths.”
Sampling manure at the time of application should be standard practice. A manure analysis that includes total salts will help to determine the level of risk if contingency application in winter is a last resort.
- Have up-to-date sample information for both the manure being used and the soil.
- Correlate the amount of manure that is being spread on the field with the field’s soil sample.
- Choose fields that have low run-off potential.
- Map the fields maintaining buffers around surface waters and other sensitive areas. Do not forget drainage tile lines.
- Understand available tools that will help determine if it is appropriate to spread on a given day, check out this article [http://msue.anr.msu.edu/news/when_is_the_best_time_to_spread_manure_to_optimize_crop_production_and_mini] by Shelby Burlew for more information on a tool that is available for Michigan farmers.

The Tulane Nitrogen Reduction Challenge is an international competition to find a significant, scalable solution to reduce nitrogen runoff from farming, a primary culprit behind vast algae blooms that cause massive annual “dead zones” in waters throughout the world.
Adapt-N competed against three others challenge finalists, Cropsmith of Farmer City, Illinois; Pivot Bio of Berkeley, California and Stable'N of Carmi, Illinois. Teams tested their innovations during a growing season on a farm in northeast Louisiana along the Mississippi River.
A 16-member advisory board of academics, scientists, environmentalists, entrepreneurs, farmers and national experts selected the winner based on crop yield, nitrogen reduction and the cost and market viability of their innovation.
Adapt-N gives farmers precise nitrogen recommendations for every section of their fields. The tool relies on U.S. Department of Agriculture soil databases, field-specific soil and management information and high-resolution weather data.
“The user enters some basic information on management practices like the date of planting, the type of corn hybrid that they are using and some information on the soil like the organic matter content,” said Adapt-N team leader Harold van Es. “We combine that with other data, notably weather data, like precipitation, solar radiation and temperature, and then we dynamically simulate the nitrogen environment in the field — in the soil and in the crop.”
The system is designed to enable farmers to reduce the overall nitrogen rate while increasing profitability.
“We can roughly reduce the environmental impact by about a third — 35 to 40 percent — and that’s both the impacts from nitrate leaching, which is the primary concern with the Gulf hypoxia issue, as well as greenhouse gas losses, which is also a big concern,” van Es said.
Tulane launched the grand challenge in 2014 to identify and nurture the most innovative and adaptable technologies to fight hypoxia. Seventy-seven teams from 10 countries entered the contest. Phyllis Taylor, president of the Patrick F. Taylor Foundation and a member of the board of Tulane, funded the effort.
“Mrs. Taylor’s vision of the Tulane Nitrogen Reduction Challenge highlights the opportunities with technological innovations. But we should see this event in a much bigger context, in my view, as a start-off point for governments, the scientific community, the fertilizer industry and farmers to raise the bar on nutrient management,” van Es said. “That will end up helping solve the hypoxia problem. It is time. And I hope that they will fully embrace these types of innovations and help farmers overcome the adoption barriers.”
Tulane President Mike Fitts thanked Taylor for her leadership in spearheading the challenge and inspiring innovators to come together to focus on a major environmental issue like hypoxia.
“This competition, this process, has set in motion some of the great minds around the world thinking about an important problem,” Fitts said. “That is what Tulane University is about. And this is such an inspired way for us to participate in solving world problems."
Participants do not need to attend all three days, and are only required to register for the first day of demos, as a free lunch will be provided to those attending. Those in need of it will also receive continuing education units from the Maryland Nutrient Management Program.
“Rising fertilizer costs require farmers to maximize the use of ‘free’ nutrients available in manure,” said a spokesperson. “Incorporating manure into the soil is an effective management strategy for keeping these valuable nutrients in the field.”
This program offers practical strategies for injecting manure into the soil to allow incorporation while maintaining a no-tillage management system. Farmers will have an opportunity to talk to custom applicators, discuss costs, and learn about cost-share programs for manure injection and manure transport.
The workshop will begin November 7 at Ganoe Farms, Frostburg, with registration, coffee, and doughnuts offered at 8:30 a.m. Demonstrations will be held from 9 to 11 a.m. at Ganoe’s. The group will then travel to Delvin, Dale, and Wayne Mast’s farm in Grantsville, where a complimentary lunch will be provided at 11:30 a.m. Guest speakers Joe Bartenfelder, Maryland Agriculture Secretary, and Norm Astle, Maryland Cost-Share Programs, will be heard until approximately 2 p.m. The day will continue at Robert Bender’s Accident farm from 2:30 to 4:30 p.m. with manure injection demonstrations. Those interested are asked to register no later than November 1 by calling the Garrett Soil Conservation District at 301-334-6951.
Additional farm demonstrations will take place on Nov. 8, beginning at Randall Steyer’s farm in Oakland, and followed by demos at Nevin’s Sines’ farm in Oakland and Kenton Bender’s farm in Accident. The last day, November 9, will also offer farm demonstrations only at David Yoder’s farm and two Grantsville dairy farms, which are yet to be determined.
Registration is not required for the November 8 and 9 farm demonstrations.
