Breaking down lignin is only the beginning of managing residue after harvest

Breaking down lignin is only the beginning of managing residue after harvest.


Once laccase opens the tough lignin barrier, the inner plant fibers become accessible to the soil’s natural biology. Microbes colonize these exposed layers and produce cellulases and hemicellulases. Unlike laccase’s broad, cascading action on lignin, cellulases and hemicellulases work more selectively, cutting specific bonds in the exposed plant fibers. Sugars are released from the enzyme action that microbes use for energy and growth.


As this cycle continues, plant-available nutrients return to the soil, carbon feeds beneficial microbes and contributes to soil organic matter, and less residue remains to interfere with crop emergence.


Effective residue management does more than reduce excess residue on surface. It helps turn this year’s residue into healthier soil and a more uniform start for next year’s crop.

After years of battling puffy tees and summer scalping, International Country Club in Fairfax, VA, says "Our tees did not scalp in July and August as in years past. The puffiness is noticeably less."
Colorado Course ThatchZyme Trial:  Poa-Bentgrass Tee
By ZymeCO • November 3, 2026
A 2026 Colorado golf course trial evaluated ThatchZyme’s effect on organic matter in a Poa-bentgrass tee. ThatchZyme reduced organic matter throughout the upper 6 cm of the turf profile, with the greatest reduction near the surface.

Jason, Bridgette, and Stephanie Wedryk dig into how residue breakdown products work, why enzymes are different from microbial products, and what farmers should actually expect from these inputs.

Biological products rely on living microbes that must survive changing field conditions or on blends of naturally occurring compounds with multiple modes of action. ZymeCO enzymes are different. They are non-living, purified proteins designed to catalyze specific biochemical reactions.

Unlike conventional leonardite-based fulvic products, FulviZyme combines plant-derived fulvic acid with naturally occurring organic acids and bioactive plant compounds.

Rather than viewing residue as something to simply manage, TillZyme helps unlock its value by helping start the biological process that turns tough plant material into a resource for the soil.

Corn residue can decompose slowly because lignin gives stalks and leaves their rigid structure. TillZyme™ uses laccase enzyme technology to help accelerate the breakdown of tough crop residue.
By Stephanie Wedryk, Ph.D. • September 2, 2026
After harvest, crop residue is not just leftover stalks and leaves. It is an active biological system that adds nutrients to the soil, increases organic matter, and builds better soil structure for next year. Actively managed residues help create a favorable seedbed for better stands and yield. The enzymes produced by fungi accelerate the process by breaking down tough lignin before naturally occurring soil microbes take over. Learn more here .
