The State of Fertilizer Sustainability

In the past few months, we’ve seen the business community make some major announcements regarding their role in combating large societal challenges. Larry Fink, CEO of the investment firm BlackRock, acknowledged that climate change is “driving a profound reassessment of risk,” and therefore they plan to realign a significant portion of their capital to match their investors’ values.

Energy giant BP announced last week that they seek to achieve net zero emissions by 2050 on not just their operations, but also on the upstream use of their products.

Now, these two companies (and several others like them) might not be who most of us turn toward to solve environmental challenges. Historically, that has fallen to NGOs, government, and academia. However, we live in a changing world that’s being turned on its head.

In January, the public relations firm Edelman released the 2020 Edelman Trust Barometer, which tracks the trends that influence and reflect people’s trust in the four major societal institutions: government, business, media and NGOs. This year’s report revealed that none of these four institutions is trusted by the public, which stems from our fear of the future and the role these institutions play in it.

It’s a wake-up call that maybe BlackRock and BP are listening to and one TFI is heeding as well.

Last month, TFI released it’s fifth State of the Fertilizer Industry Report – or unofficially the industry’s sustainability report. The report has been tracking industry performance on various environmental, social, and economic indicators for five years. And I’m pleased to say the industry is making progress!

Some of the highlights include:

  • The industry is more than twice as safe as industry peers when compared to benchmark data from the Department of Labor.
  • The fertilizer industry delivers more than $130 billion in economic impact in the United States.
  • Total energy use per nutrient ton of fertilizer produced decreased 3 percent from the prior year.
  • The industry captured more than 4.5 times the greenhouse gas emissions that were captured in 2013. These captured emissions were then used for other industrial purposes.
  • Nitrogen producers are using half the amount of water per nutrient ton produced than they did in 2013.

The report showcases data on all segments of the fertilizer industry from fertilizer use on the farm, the impact on people and communities, energy and environment, and transportation. For the first time this year, TFI is able to report that nearly 6 million tons of recycled materials were used in the production fertilizer.

And while the report contains more data, there’s still much work to be done to make progress on these metrics. Last year, TFI’s Board of Directors approved a new organization strategic plan. And in a sign that this industry also “gets it,” one of the three pillars of the plan is a commitment to the environment.

The board identified their commitment to reducing the environmental footprint of the production and use of fertilizer. And building on the successes highlighted through five years of reporting, the industry will continue to invest in more efficient production facilities that use less water and energy while emitting fewer GHGs.

On the use side, the industry continues to expand the reach of the 4R Nutrient Stewardship initiative. This past year the state of Florida implemented the 4R Certification program, which certifies fertilizer retailers and crop consultants – those who apply or make fertilizer recommendations – are following business practices in accordance with 4R Nutrient Stewardship principles. Similar efforts are underway in a number of other states. All of which helps to significantly reduce and prevent fertilizer from running off fields into the water supply.

The TFI staff have also been working diligently over the past several years to quantify the benefits of 4R practice implementation on the farm. And I’m excited to say that we’re making progress on this front as well. We know that cost is an important consideration for farmers when thinking about any practice change. To answer these questions, we have developed a host of case studies showcasing how farmers across the United States have seen costs go down, yield go up, and environmental impact lessened through using 4R-based practices. You can learn more at 4Rfarming.org.

The fertilizer industry employs more than 103,000 people in the United States. To capture their work and impact, the State of the Industry Report features interviews with employees across the value chain, including those who partner with the industry on research and stewardship initiatives. Take a listen and hear from the industry in their own voice.

Ecosystem Services Market Consortium and The Fertilizer Institute Launch Pilot

WASHINGTON, Feb. 27, 2020 – The Fertilizer Institute (TFI) and the Ecosystem Services Market Consortium (ESMC) announced today at Commodity Classic plans to test improved nutrient stewardship as a means of increasing farmer profitability through the ecosystem services market being developed by the ESMC. This pilot project will test the ESMC’s protocols and data intake procedures and other program aspects while TFI will identify potential buyers for the ecosystem service impact credits generated.

The Fertilizer Institute will work with farmers enrolled in their 4R Advocate Program in Illinois, Indiana, Iowa, Minnesota, Missouri, Ohio and South Dakota. TFI’s 4R Advocate Program links nutrient stewardship, including precision agriculture and variable rate application, to farm profitability and has collected production data, including fertilizer applications, from participating producers for four years.

4R Nutrient Stewardship principles incorporate the right source, right rate, right time, and right placement of fertilizer and are a proven framework that helps American farmers increase production and profitability while enhancing environmental protection and improving sustainability.

ESMC’s science-based, outcomes-based protocols and program generates credits for soil carbon (C), net GHG, water quality and water use efficiency. The collaborative effort with TFI will enable ESMC to secure producer intake data information to establish baseline attributes and to quantify impact changes over time; to capture, store and manage data required for ESMC asset generation; and to evaluate strengths and gaps in meeting corporate reporting needs and requirements for GHG and water risk, water quality, and water use efficiency.

“This pilot presents TFI and its members with an opportunity to prove the financial cost-effectiveness and environmental benefits of 4R Nutrient Stewardship principles,” said Corey Rosenbusch, TFI President and CEO. By overlaying the ESMC platform currently under development to generate ecosystem services impact credits with TFI’s existing 4R tracking of nutrient stewardship and profitability, the pilot is intended to show a significant correlation between these goals.

“This landmark-setting pilot is an example of industry collaboration coming together to resolve our thorniest environmental challenges with common sense market-based solutions to reward producers,” said Debbie Reed, Executive Director of the ESMC. ESMC is launching several more pilots this winter and spring in the Midwestern corn and soy region, focusing on row crop and grain production systems. The ESMC is building a national-scale ecosystem services market designed and conceived for the agricultural sector. It plans a 2022 full market launch of its Ecosystem Services Market. ESMC seeks to enroll 30 percent of available working lands in the top four crop regions and top four pasture regions to impact 250 million acres by 2030.

The Fertilizer Institute Applauds USDA’s Agriculture Innovation Agenda, Seeks to Gain Government Commitment to Fund 4R-Related Research

WASHINGTON, Feb. 24, 2020 – The Fertilizer Institute (TFI) announced its support for the U.S. Department of Agriculture’s “Agriculture Innovation Agenda,” which the agency bills as a “solution for farmers, consumers, and the environment.” TFI will continue working with USDA to find practical solutions to increasing the adoption of 4R Nutrient Stewardship practices among farmers. 4R principles incorporate the right source, right rate, right time, and right placement of fertilizer and are a proven framework that helps American farmers increase production and profitability while enhancing environmental protection and improving sustainability.

“I applaud Secretary Perdue and the team at USDA for their commitment to sustainable agriculture, and TFI fully supports this new initiative,” said Corey Rosenbusch, TFI President and CEO. “The Fertilizer Institute has long promoted similar goals, including 4R Nutrient Stewardship, and I look forward to future cooperation with the department as we work toward advancing these shared objectives to benefit American agriculture.”

TFI and its members are committed to being part of the solution when it comes to innovation and sustainability in agriculture. TFI members are well-positioned to work with farmers in areas such as technical assistance and writing and implementing nutrient management plans based on the 4Rs. 

Through the 4R Research Fund, TFI is also committed to measuring the outcomes of 4R practices. The 4R Research Fund has led to $17.2 million in research efforts through private and public collaborations. The Agriculture Innovation Agenda presents an excellent opportunity to leverage private sector funds with public sector research dollars to quantify the environmental benefits of implementing suites of 4R practices on the farm. In fact, the 2018 Farm Bill designated 4R-based research as a high-priority research area.  

In addition, USDA’s Agriculture Innovation Agenda is based on a report by the National Academies, “Science Breakthroughs to Advance Food and Agricultural Research – 2030,” which identifies research needs compatible with the 4Rs.

Finally, improvements in data collection by USDA would enable a better understanding of how cropping system management decisions interact with environmental properties or conservation practices. The inclusion of data that focuses on management, however, could be improved to account for nutrient management strategies such as fertilizer source, rate, time, and place.

The Fertilizer Institute’s 5th State of the Fertilizer Industry Report Highlights Improvement in Environmental Impact, Safety, and On-Farm Fertilizer Use

WASHINGTON, Feb. 18, 2020 – The Fertilizer Institute (TFI) today released its fifth State of the Fertilizer Industry Report. The report tracks social, environmental, and economic metrics across the entire value chain to identify industry progress and mark areas for improvement. Since 2013, the industry has made significant improvements in water use, greenhouse gas emissions, and research on and adoption of 4R Nutrient Stewardship practices.

“The business community is making sustainability a priority, and the fertilizer industry is no different,” said Corey Rosenbusch, TFI President and CEO. “As TFI marks five years of collecting sustainability data, I am excited to be able to look back at the accomplishments we’ve made while also charting a path to where we want to be in the next five years and beyond.”

This year’s report includes data representing 34 companies in the manufacturing, retail, and wholesaler and distributor space. The data represents 91 percent of manufacturing capacity and 32 percent of the retail industry in the United States. Report highlights include:

  • The industry is more than twice as safe as industry peers when compared to benchmark data from the Department of Labor.
  • The fertilizer industry delivers more than $130 billion in economic impact in the United States.
  • Total energy use per nutrient ton of fertilizer produced decreased 3 percent from the prior year.
  • In 2018, the industry captured more than 4.5 times the greenhouse gas emissions that were captured in 2013. These captured emissions were then used for other industrial purposes.
  • Nitrogen producers are using half the amount of water per nutrient ton produced than they did in 2013.

The report showcases data on all segments of the fertilizer industry from fertilizer use on the farm, the impact on people and communities, energy and environment, and transportation. For the first time this year, TFI is able to report that nearly 6 million tons of recycled materials were used in the production fertilizer.

The fertilizer industry employs more than 103,000 people in the United States. To capture their work and impact, the State of the Industry Report features interviews with employees across the value chain, including those who partner with the industry on research and stewardship initiatives.

Increasing Interest in Fertilizers Bodes Well for Industry

This article was originally published in the January/February 2020 issue of Argus Media’s Fertilizer Focus magazine.

With 2019 in the books, fertilizer industry leaders note the realities of a year that dealt with bad weather, worldwide political challenges and routine market cycles. This in no way dispels their optimism for 2020 and beyond. In fact, they’re realistic that some years will be challenging, while others will deliver more opportunities than can be expected.  

Data for the fifth State of the Fertilizer Industry Report is being verified by The Fertilizer Institute (TFI) as this issue of Fertilizer Focus goes to press. It will be presented in mid-February during The Fertilizer Institute’s Annual Business Conference. Initial observations of the data confirm experts’ observations that the long-term direction of the fertilizer industry is on an upward trajectory.

Magnus Ankarstrand is president of Yara North America. He says a strong nitrogen market has given rise to an increase in nitrogen production from 2016 onwards, as well as improved production efficiency.

“We’ve seen an increase in production, particularly on the nitrogen side that affects us,” he says. “Capacity in North America was achieved fairly quickly, but additional capacity in China and North Africa has followed, although it is not likely additional nitrogen projects make sense in the near term. For Yara, it’s been important to ensure we continue to make our production more efficient, such as decreasing gas consumption per ton of ammonia produced.

“It’s also been important to expand our downstream distribution,” Ankarstrand adds. “Our ability to distribute our products to cooperatives and retailers worldwide and have infrastructure and alternative outlets in different markets to deliver products all over the world has been extremely important to us, in addition to delivering superior knowledge about crop nutrition to farmers.”

Mike Hamilton, vice president, business director for Plant Nutrients at AdvanSix, says while economics for growers continue to be a struggle, it’s important to keep market cycles in mind.

“We continue to see market cyclicity for fertilizer and crops, in general,” he says. “While today’s market is fairly weak, there is a growing need for more food and grain. I think most market participants expect things to rebound.”

 

Market challenges, industry issues are opportunities

This aligns with observations of The Fertilizer Institute. In addition to normal market fluctuations, there has been a transformational shift in interest of the fertilizer industry from insiders and outsiders alike. This signals an overall positive for upcoming years.

“Stakeholder interest in the fertilizer industry continues to increase, whether that focus stems from water quality, climate change or general sustainability/sustainable sourcing considerations by the food supply chain,” Lara Moody, TFI vice president, stewardship and sustainability, says. “Stakeholders increasingly look to industry retail members as farmers’ advisers to bring about change that leads to reduced nutrient loss and sustainably grown products. Manufacturers and producers feel pressure each time our products are linked to algal blooms, eutrophication, ammonia losses and climate change.“

Ankarstrand concurs.

“In the last few years, especially the last couple, there has been a significant increase in the whole sustainability discussion around agriculture,” he says. “This interest is accelerating. The increased focus on the carbon footprint of agriculture in general, and especially fertilizer issues, such as leaching, runoff and water management have become big issues.

“Quite clearly these are becoming big topics, but what’s important for us as a company and for the industry as a whole, is to provide a solution that solves these issues with current technology using available methods, such as the 4Rs,” he adds.

 

Addressing issues now

As noted in previous editions of the State of the Industry Report, the industry is ahead of the game when it comes to advances. The 2019 edition is expected to deliver the same.

“Some of the trends we’ve measured through members are important points we are able to use in advocacy,” Moody says. “Since 2014, the industry has continued to increase the percentage of greenhouse gas (GHG) emissions captured during nutrient production, our safety record remains well below that of our peers and we’ve seen a continued increase in enhanced efficiency fertilizer use.”

On-farm adoption of 4R practices continues to progress. TFI is developing case studies to help growers see how the 4Rs can benefit individual operations’ bottom line.

In 2017, TFI conducted research to understand what the barriers and consideration farmers face when implementing practice change. Moody says cost was overwhelmingly identified as the top consideration. She adds that while cost is simple to identify, it is more complex to show farmers the economic benefits of practice change.

“Because practices are linked to management systems, costs from equipment changes and fuel usage to labor and changing input costs must be considered. Cost savings or increases linked to practice change come from a variety of management decisions. Understanding where they originate puts more information in the hands of farmers and crop advisers. By developing case studies in multiple geographies and various cropping systems, we hope farmers will be able to see examples that look somewhat like their own operations, Moody says.”

In addition to TFI’s own research on the benefits of 4R Nutrient Stewardship, its members conduct research to improve use of their products. AdvanSix has examined the agronomic benefits of split-applying nitrogen and sulfur. Hamilton says they have found that performing a pre-plant or at-plating application and then applying ammonium sulfate later in the cycle, gets the nutrients where and when the plants need them. Plus, there are fewer environmental losses.

“This improves grower economics because they’re getting more efficient plant nutrition,” he says. “This is important for the industry and society as a whole.”

As Yara has increased production capacity, it also found a way to tap by-product hydrogen from other producers in the Freeport, Texas, area and use it to produce in a sense, hydrogen-free ammonia.

Ankarstrand and other company leaders are looking ahead, too. Yara has invested in incubator farms in Alabama and California in the United States and in Saskatchewan in Canada. All represent a substantial investment into crop nutrition knowledge and research and development. However, the California farm includes tree crops, so the commitment is strong for a long-term, year-over-year study of nutrient use.

For the last two years, AdvanSix has issued its own sustainability report. Hamilton says it is a comprehensive document that looks at issues from an overall business perspective and supports the company’s goal of being transparent.

 

Understanding of existing nutrients expanding

Opportunities for nitrogen, phosphorous and potassium will continue to grow, as well as those for other nutrients, especially sulfur.

“In the last 10 to 15 years, we’ve seen an increase in awareness of the understanding of the need for sulfur,” Hamilton says. “It has accelerated a bit more because over the same period of time, we’ve seen a significant reduction in SO2 emissions from sources like coal-fired power plants. Because of this, US sulfur deposition has decreased and the need for growers to invest in sulfur nutrition is increasing. We see this with sulfur demand.”

It’s not just the United States, Hamilton says.

“We don’t believe China and India use enough sulfur,” he says “Even soybeans in the United States could benefit from more sulfur. We’re conducting research on this now. Most of our research is completed in partnerships with agricultural universities. Their researchers perform great work and growers look to university researchers as non-biased advisers.”

 

Opportunities abound

These advances and changes in thinking create opportunities for all industry players. TFI’s Moody says most leaders are embracing them from the top down.

“At TFI, we have ramped up 4R efforts for the last decade. We have been able to take ownership of our part of the nutrient loss problem and more importantly, own a solution. The 4Rs allow us to lead with science and bring a wide range of stakeholders with us from state and federal agencies, academia, conservation and commodity groups. We’ve also ramped up our knowledge of industry efforts with the data collection required for the State of the Industry Report. It gives us awareness of multiple efforts across the fertilizer supply chain that we use to inform our advocacy efforts and decisions, as well as our stakeholders. Industry members can also use the data to perform internal assessments relative to industry averages.”

The key is continued cooperation, Hamilton says.

“Part of our challenge is to continue to communicate,” he says. “Fertilizer is important to ensure people have enough to eat. How we communicate its relevance will be key to success at all levels.”

Aiding this much-needed communication is one use of the new State of the Industry Report, Moody says.

“Sustainable food choices, water pollution and climate change remain at the forefront of discussions and in the media,” she says. “We also hear more about environmental, social and governance (ESG) reporting for publicly traded companies. Our 4R and State of the Industry Report are tools the fertilizer industry can use as they navigate these issues.”

TFI Applauds Trump Administration’s Finalization of WOTUS Rule

WASHINGTON, D.C. – The Fertilizer Institute (TFI) Vice President of Stewardship and Sustainability Lara Moody issued the following statement regarding the Trump administration’s finalization of the Environmental Protection Agency (EPA) and Department of the Army repeal and replacement of the 2015 Waters of the United States (WOTUS) rule.

“The fertilizer industry strongly supports the EPA’s and the Department of the Army’s new WOTUS rule, which provides a sustainable national water policy that both protects the environment and facilitates smart economic development. The new rule more clearly defines which waters are subject to federal jurisdiction and which waters are subject to state protection, clarity that was severely lacking in the 2015 rule.

“We have long shared EPA’s goal of improving water quality and continuously advocate for the adoption of nutrient management practices such as 4R Nutrient Stewardship (using the right fertilizer source, applied at the right rate, at the right time and in the right place) that enhance environmental protection while helping to ensure farmer profitability.

“We applaud the Trump administration, the EPA and the Department of the Army for their efforts to ensure a future with both clean water and clear rules.”

TFI Statement on Intergovernmental Panel on Climate Change’s August 8, 2019, Status Report

Agriculture is at the frontline of adaptation to climate change. In the last twelve months, the record-breaking flood events and challenging precipitation frequencies in the Midwest challenged farmers and the fertilizer industry to adapt to a dramatically shortened fall field work and spring planting season.  

The Intergovernmental Panel on Climate Change (IPCC) report released today cautions that land must remain productive to feed a rising world population and highlights the importance of fertilizer application rate and timing to maintain production potential and reduce environmental quality impairment. We believe that the efficiency of fertilizer use is central to the goal of successful adaptation to changes in environmental conditions. 

The fertilizer industry is committed to the sustainable use of its products using the 4R Nutrient Stewardship framework (use of the right fertilizer source, at the right rate, the right time, and in the right place). This science-based, site-specific approach is contributing to incredible progress in minimizing the impact of fertilizer use has on our nation’s air and water resources. Since 1980, U.S. farmers have more than doubled corn production using just 6.9 percent more fertilizer. Considering that emissions from agricultural operations have been relatively flat since 1990, this is tremendous progress.

Still, there is much more work to be done. Science-based decision making should be the foundation for the adoption of climate smart technologies and practices for sustainable agriculture and global food production. The 4R Research Fund, which is supported by the fertilizer industry and other key stakeholders supports integral research and provides information to help farmers maintain the cycle of continuous improvement.

Beyond farm fields, minimizing greenhouse gas (GHG) emissions is also a priority for companies that produce fertilizer. The industry captures CO2 emitted during ammonia production and re-uses it during the production of urea, another nitrogen fertilizer. Excess CO2 captured from fertilizer production is also recycled for other industrial use, such as enhanced oil recovery and the carbonization of soft drinks.

In 2017, the industry captured and re-used 7.5 million metric tons – which is 24 percent of all GHGs emitted by the industry throughout the year.  This is a dramatic increase compared to 2013, when the industry captured and re-used 9 percent of its GHGs. 

 

 

 

Lake Erie – A Complex Equation for Agriculture

Ecosystems are complex, as is our understanding of the factors affecting them. The Western Lake Erie Basin and the watershed that feeds it is as amazing as it is confounding. Many factors affect the potential for harmful algal blooms in Lake Erie, and as a recent report by the International Joint Commission indicates, just looking within the agricultural landscape elicits an array of contributing factors – many of which are not easily managed.

Phosphorus that is intentionally trapped in installed buffer zones, filter strips, wetlands, riparian zones, ditches and drains, as well as river channels, may be shifting away from these phosphorus sinks and becoming slow releasing phosphorus sources. Agricultural soils in general can also be a slowly releasing phosphorus source. The beneficial and widely adopted practice of conservation tillage systems, initiated in the 1980s to reduce erosion and loss of particulate phosphorus as well as to improve soil health, is contributing to increased dissolved reactive phosphorus loss from fields over time. Without soil disturbance, phosphorus accumulates in the upper most layer of the soil. And combined with high rainfall patterns linked with changing climate conditions, an increasing load of dissolved reactive phosphorus is entering the Lake Erie’s tributaries as a result of increased water flows.

The International Joint Commission (IJC) recently released a report, “Fertilizer Application Patterns and Trends and Their Implications for Water Quality in the Western Lake Erie Basin,” which assesses fertilizer application and impacts in the region. As the report points out, the region is complex and the factors mentioned above only tell part of the story.

There are other contributing factors, like the use of commercial and manure fertilizer sources, which can be managed to the benefit of lake and to farming operations in the watershed. The IJC report notes that broader implementation of a mix of current best management practices is a critical strategy to restoring the health of Lake Erie. Specifically, it notes that adoption of 4R nutrient stewardship (the right fertilizer source applied at the right rate, the right time, and in the right place) can have a positive influence on reducing phosphorus loss from agricultural lands – with timing, rate, and placement being of particular importance. Models also indicate that combinations of nutrient management with various land management practices are necessary to realize a significant reduction in phosphorus loading through Lake Erie tributaries.

The complex equation for agriculture to help reduce the potential for harmful algal blooms in the Lake is not yet solved, and as the IJC report recommends, we all have more to do. The fertilizer industry and our stakeholders continue to promote and support adoption of 4R practices on the farm, through initiatives such as the 4R Nutrient Management Certification Program. And efforts to evaluate the effectiveness of 4R and other best management practices at field and watershed scale must be continued and expanded to identify areas of improvement, something The Fertilizer Institute is pursuing through the 2018 Farm Bill as well as with our own members via the industry’s 4R Research Fund

Reducing algal blooms in Lake Erie will take time, but we must act on what we know and continue to be pragmatic in our solutions.
