How companies can reduce nitrogen pollution and measure progress toward climate goals

Nitrogen is essential for life, but excess nitrogen can pollute the atmosphere and water. This has a huge impact on human and ecosystem health, as well as financial losses to farmers from fertilizer — which is at a record high price — that ultimately won’t be utilized by crops.

EDF’s new N Balance Implementation Guide provides a comprehensive and pragmatic road map for food and agriculture companies to help reduce nitrogen pollution from agricultural production and claim the environmental improvements associated with nitrogen management.

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 »

Anticipating sharp declines in 2021 farm profitability, experts suggest cost savings from fertilizer efficiency

Farmers across the country may not see profitable conditions for some time as the effects of COVID-19 suppress already meager profit margins.

Projections from the University of Illinois and the University of Missouri show that farm profits could fall significantly in 2021, and economists are recommending farmers examine fertilizer application and tillage passes for the potential to provide highly needed cost savings. Read More »
