This segment of the Illinois Nutrient Loss Reduction Podcast, featured on the Closing Market Report, examines the agronomic impact of the soil microbiome through an interview with Waypoint Analytical’s Dr. Lizzie French. The soil microbiome consists of microscopic organisms-including bacteria, fungi, and nematodes-that cycle nutrients, process crop residues, and build soil structure.
Waypoint Analytical measures this biological activity using DNA analysis to identify the specific functional capabilities of these microbes, such as their ability to fix nitrogen or solubilize phosphorus. French asserts that implementing conservation practices, including cover crops, reduced tillage, and tile drainage management, provides the necessary habitat and carbon inputs to sustain microbial populations and prevent nutrient runoff. By testing and understanding their soil’s biological capacity, producers can optimize fertilizer efficiency and potentially reduce nitrogen applications in soils with robust organic matter, though French cautions that maintaining proper soil pH remains the most critical foundational step for supporting biological activity.
