Edge-of-field (EOF) conservation practices—established on field boundaries, outside of productive cropland—are designed to help reach Iowa’s water quality goals, especially when paired with in-field practices. The “Giving Clean Water the Edge” infographic series dives into how EOF practices work, their positions on the landscape, their impacts on water quality, and the additional co-benefits that many EOF practices offer.

Conservation practices are crucial for sustainable agricultural production and the preservation of healthy ecosystems. These practices significantly enhance soil health, water quality, and biodiversity, and reduce greenhouse gas emissions. Edge-of-field (EOF) practices, such as saturated buffers, bioreactors, and water quality enhancement wetlands, play a pivotal role in improving water quality by effectively reducing nutrient loads and fostering wildlife habitats.

Widespread adoption of edge-of-field (EOF) practices—such as saturated buffers, bioreactors, and water quality enhancement wetlands—is vital to achieving the goal of 45% nutrient reduction outlined in the Iowa Nutrient Reduction Strategy. However, few farmers in the state have embraced EOF practices on their land—this project investigates why.
