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.
