4 lessons learned from nitrogen balance pilot projects

Environmental Defense Fund led several pilot projects in the 2019-2020 growing season to better understand how different farm management practices impact nitrogen balance, or N balance, a robust and practical proxy to measure agriculture’s climate and water quality impacts.

EDF scientists assessed real-world, in-field data for 16 management practices and N balance scores from more than 500,000 acres of corn across nine Midwestern states. Here are four actionable insights. Read More »

A breakthrough to measure agriculture’s environmental impact

Nitrogen (N) is essential for high crop yields to feed a growing population, but excess nitrogen contributes to climate change as nitrous oxide and to water pollution as nitrate.

Historically, measuring nitrogen losses has been expensive and time consuming. Environmental Defense Fund’s N-Visible framework remedies that.

N-Visible provides an easy-to-use, scientifically robust way for farmers and their advisers to assess nitrogen losses from individual fields. It also allows food companies and policymakers who promote on-farm sustainability to measure progress toward improved environmental outcomes at regional scales.

An open-source implementation guide is now available for download. Here’s what it contains and how to use it. Read More »

Small grains have big outcomes for climate resilience

Small grain crops, like oats and wheat, are making a comeback in the Midwest, disrupting the traditional corn-soy rotation and delivering big benefits for farmers and the environment. And they’re about to get another big boost.

The U.S. Department of Agriculture recently awarded a $1.1 million Conservation Innovation Grant to Practical Farmers of Iowa to advance the use of small grains crops and test market-based solutions for lowering emissions linked to nitrogen from manure and fertilizer. Read More »

Three takeaways from the largest-ever dataset about fertilizer management in North Carolina

In the face of uncertainty about everything from variable weather to market prices, fertilizer is one variable that farmers can control — but only if they have access to actionable, scientific information about how to select the appropriate application rate and tools.

A new report, Nitrogen management in North Carolina agriculture: Results from five years of on-farm research [PDF], helps fill this need. It provides the most comprehensive dataset ever collected about on-farm nitrogen management practices in North Carolina to identify fertilizer solutions that increase operational resilience, and improve economic and environmental outcomes.

These findings are the result of five years of participatory on-farm research through the North Carolina Farmer Network, a group of crop consultants and nearly 100 farmers across 26 counties in North Carolina’s eastern Coastal Plain.

The network formed through a collaboration between Environmental Defense Fund, North Carolina Farm Bureau, North Carolina State University, North Carolina Foundation for Soil and Water Conservation, and others.

As grain farmers and their advisers gear up for the 2019 growing season, here are three top findings from the network’s research to consider. Read More »

$1 million USDA award expands public-private partnerships for ag sustainability

A collaboration between Smithfield Foods and Environmental Defense Fund has reduced fertilizer loss and improved soil health on more than 400,000 acres in the regions where Smithfield sources feed grain. That acreage is set to grow thanks to a new USDA Regional Conservation Partnership Program (RCPP) award of $1,080,000.

The RCPP project will expand Smithfield’s ongoing grain sustainability efforts in North Carolina and scale up the program in Iowa, providing additional opportunities for farmers interested in improving their operations. Participating farmers will be supported by the combined efforts of 16 partner organizations, which include producer groups, government agencies, universities and nonprofits. Read More »
