Soil is the foundation of Wisconsin’s agriculture. Soil particles eroding from agricultural lands both degrade the soil resource, potentially reducing agricultural productivity, and pollute rivers and streams, which impacts Wisconsin aquatic ecosystems. Decades of technical, educational, and financial assistance to land managers have in many places substantially reduced this form of non-point pollution. However, progress is often slowed or stalled by decreases in government attention and oversight, and by evolving agricultural practices for both food and fuel. Recently, rising demand for agricultural products and changing precipitation patterns threaten to eliminate or even reverse progress toward minimizing soil erosion impacts on water quality.
