From Macro to Micro: Following Mulch Fragments Through the Soil

About this episode

This episode explores the degradation of biodegradable mulch in soil through insights from a multi-state field experiment.

In this episode of Mulch Matters , host Dr. Nataliya Shcherbatyuk sits down with Washington State University PhD researcher Xueyu Zhou to dig into what really happens to biodegradable mulch once it's tilled into the soil. Xueyu shares insights from a multi‑state field experiment spanning Washington, Nebraska, Florida, and California, where the team tracks mulch fragments—from large pieces to microplastics—over time. She explains how soil conditions, climate, and microbial activity shape the degradation process, and why strawberries are an ideal crop for testing these materials under real‑world conditions. Listeners will learn: Why biodegradable mulch behaves differently across regions How researchers collect and analyze mulch fragments in the field What early results reveal about degradation after one year Practical considerations and limitations farmers should keep in mind What future research is needed to understand long‑term soil impacts Whether you're a grower, researcher, or simply curious about sustainable agriculture, this episode offers a grounded, science‑based look at biodegradable mulch and its potential role in more sustainable production systems. Note: intro and…
