Saturated Buffers

A saturated buffer resembles a traditional buffer or filter strip, but it is designed to capture and treat water from underground tile drains. As water seeps slowly through the buffer, high organic matter in the soil promotes denitrification.

Illinois Nutrient Loss Reduction Strategy & Agricultural Conservation Practices

This 1-pager created by Illinois Extension, gives a brief overview of the Illinois Nutrient Loss Reduction Strategy (INLRS), highlights nutrient loss in Illinois, impacts of nutrient loss, and conservation practices that can address in-field and edge of field nutrient loss.

ISAP’s Edge-of-Field Incentive Directory

ISAP’s Edge-of-Field Incentives Directory provides an overview of edge-of-field (EoF) incentive payment opportunities for farmers in Illinois. EoF practices are defined as those practices which intercept, capture, and treat subsurface drainage (conservation drainage practices) or surface runoff at the field level. The conservation drainage practices include bioreactors, constructed wetlands for tile-drainage treatment, drainage water management, drainage water recycling, and saturated buffers. Surface runoff practices include vegetated riparian buffers, filter strips, prairie strips, and restored wetlands. The directory also includes a “Stacking Matrix” so farmers can easily determine if they may be eligible to stack payments from multiple programs.
