How Smithfield’s landmark climate goal benefits farmers and the planet

Smithfield Foods, the world’s largest pork company, is known as a leader in animal agriculture. Now Smithfield is showing its sustainability leadership by becoming the first major livestock company to make an absolute, supply chain commitment to reduce greenhouse gas (GHG) emissions that contribute to climate change.

The company will reduce emissions in its U.S. supply chain, from feed grain to packaged bacon, 25 percent by 2025. To meet the goal, Smithfield will improve fertilizer use on feed grain, install advanced manure management technologies, and increase energy efficiency in transportation.

When a company as big as Smithfield makes a new sustainability commitment, it’s natural for farmers and neighboring communities to wonder how it will affect them. The good news is that all the actions Smithfield plans will generate benefits both for farmers and our environment.

Denny Friest is one of the most progressive and savvy farmers I’ve ever met. Through his participation in the Iowa Soybean Association’s On-Farm Network since 2001, Denny conducted replicated strip trials on his operation to compare different nitrogen application rates and find ways to be more efficient and profitable.

The Iowa legislature saw so much value in this field trial program that it provided funding to reimburse farmers who lost yield in their efforts to improve efficiency. With no risk involved, Denny was able to see “how low he could go” with fertilizer applications before he had an economic loss in production. Read More »

Floodwaters powered by Hurricane Matthew’s heavy rains are finally receding in eastern North Carolina. Now farmers, communities, and state officials are beginning to take stock of their losses and think about the future.

Here are four lessons we should learn from the devastating storm.

1. Plan for the new normal

In the past 17 years, North Carolina has been hit by two storms causing 500-year floods. Hurricane Floyd in 1999, and Hurricane Matthew this past month. Both hurricanes caused extensive damage and loss of life. But Floyd in particular was especially devastating to animal agriculture and the environment. Read More »

Western ranchers, Midwestern commodity crop growers, fishermen who make their livelihoods along the Mississippi River and the Gulf Coast. In some circles, these folks wouldn’t necessarily be considered models of sustainability. And yet, many are leading a quiet revolution in the way our food is raised, harvested and produced.

In her new book Rancher Farmer Fisherman: Conservation Heroes of the Heartland, my colleague Miriam Horn journeys down the Mighty Mississippi River System to meet five representatives of this unsung stewardship movement: Read More »

Two ways to reduce toxic algal blooms

For a month now, South Florida Atlantic beaches have been blanketed by a sickly green, toxic algae sludge that has kept tourists away and caused local businesses to lose millions.

Florida has a bigger headache this summer than most states, but algae blooms are hardly unique.

Last week, more than 100 people were sickened from toxic algae in a Utah lake largely fed by agricultural runoff and treated sewage water. And just two summers ago, an outbreak in Lake Erie forced the City of Toledo to close off its water supply for nearly half a million residents.

Agricultural runoff also means wasted money for farmers, who can spend approximately half of their input costs on fertilizer.

There are ways to reduce the runoff that contributes to water quality problems and kills marine life, year after year. Algae blooms can be minimized and maybe even prevented if we scale up existing efforts to improve fertilizer efficiency and soil health – practices that can also save farmers money and boost their yields.

Two initiatives and private-sector partnerships are making real headway in doing just that. And if these efforts are replicated at scale, they could have a national – and even international – impact. Read More »

Why collaboration between ag equipment and tech companies is a good thing for the environment

In order for the agriculture sector to deliver on the growing demand for sustainable grain and participate in emerging carbon markets, growers need a way to demonstrate that their management practices are benefiting the environment.

Scientists have identified multiple practices that farmers can implement to maximize yield while minimizing impacts to air and water. Meanwhile, companies such as Trimble Ag, John Deere, SST Software, and countless others have developed a wide array of sensing tools and data collection methodologies to calculate and monitor the environmental benefits of these practices.

Yet as one might expect in any emerging market, the tools aren’t fully communicating with each other, thereby limiting their true potential.

The good news is that the makers of these technologies have started collaborating with agricultural practitioners to make their systems more compatible. Even in this fragmented industry, companies are starting to work together to streamline data collection – and this has enormous implications for sustainability.

Here’s why. Read More »

Controlled drainage is the new black

Dr. Mohamed Youssef demonstrates the benefits of controlled drainage.

NC State University’s agriculture water management expert Mohamed Youssef, Ph.D, believes the time is ripe for controlled drainage to make a comeback.

Controlled drainage is one of the most effective ways to minimize nitrogen loss from croplands. It’s a management practice involving the use of a control structure installed at the outlet of a drainage ditch or subsurface drain to regulate drainage water outflow according to plant needs and field operations.

“A controlled drainage system can remove between 40 and 60 percent of the nitrogen present in runoff, if used at a large scale. These systems hold huge potential to reduce pollution from very large flows of water runoff,” Youssef explained during my recent visit to NC State’s demonstration farms in eastern North Carolina.

Despite the promise, adoption rates for this practice remain very low, in part because of functionality problems with the first controlled drainage structures. But thanks to new advances in the technology that I recently viewed in the field, adoption rates are rising.

Like any filter practice, controlled drainage is just one tool that can help solve regional water quality problems. It’s not a silver bullet, especially with some geographic limitations since they can be used only on low-sloping fields. While there is no perfect solution to stop farm runoff, after seeing drainage systems first-hand, I too believe we’re nearing a tipping point for widespread adoption of controlled drainage in agriculture – and big environmental benefits. Here’s the story. Read More »

New guidebook explains how and why to build a farmer network

Amidst all the new tools and technologies being developed to make agriculture more sustainable, there is one tried and true method for testing on-site conservation practices that doesn’t get much attention: farmer networks.

Farmer networks consist of growers within a region working directly with advisors, agronomists and/or scientists to conduct on-farm trials. These trials can test the economic and environmental impacts of changes in crop management, adoption of soil health practices, or use of precision agriculture tools.  The data is then aggregated and analyzed to determine best practices for specific farm conditions and to inform future management decisions.

Originally established by the Iowa Soybean Association, the innovative farmer network model has since taken off, with Environmental Defense Fund and others establishing additional networks across the country. As University of Connecticut soil fertility expert Thomas Morris explains, participation in farmer networks has led to greater efficiency on hundreds of thousands of acres across the U.S – benefitting both the planet and yield. The potential for replication is limitless.

That’s why EDF created a how-to guide for other organizations, companies, and universities interested in creating a farmer network. The new Farmer Network Design Manual provides a roadmap to support sustainable agriculture practices, increase farm profits, and build resiliency. Read More »

The key ingredient in a resilient food supply: healthy soil

Dec. 5 is World Soil Day.

Dec. 5 is World Soil Day.

Last year, the United Nations General Assembly declared December 5th as World Soil Day. This annual event aims to “connect people with soils and raise awareness of their critical importance in our lives.”

As the Food and Agriculture Organization of the U.N. notes, we often ignore soil’s key role in our food systems, climate, and in sustaining biodiversity. Today, 33 percent of the planet’s soils are considered degraded – and this has vast implications for meeting the world’s growing demand for food.

In honor of World Soil Day, I asked Nick Goeser, Ph.D., soil health and sustainability manager for the National Corn Growers Association, to elaborate on why soil really matters.

How is soil health tied to food production? Read More »
