The concern about nitrogen depletion from wood chip mulch is a common misunderstanding that often deters gardeners from using an excellent organic material.

Surface vs. Incorporated: Nitrogen immobilization primarily occurs when high-carbon materials are mixed into the soil, not when they sit on top.

Decomposition Zone: The main decomposition of surface mulch happens where it meets the soil, a zone less critical for active nutrient uptake by plant roots.

Nutrient Release: Over time, as wood chips break down, they actually release nutrients, including nitrogen, back into the soil, improving long-term fertility.

Benefits Outweigh Risks: Mulch significantly conserves moisture, suppresses weeds, and moderates soil temperature, offering more advantages than any minor, localized nitrogen tie-up.

I'm just sayin'!
