Turning Stalk into Soil: Composting with Hemp Fiber

1. Benefits of Hemp Fiber in Compost

2. Preparing Hemp Fiber

• Shred Before Composting: Smaller pieces (<4") increase surface area and speed up decomposition.

• Check Moisture: Damp but not wet—ideal humidity supports microbial activity.

3. Composting Process

1. Layering: Alternate shredded hemp fiber with green materials (food scraps, grass clippings) in a ratio of ~2:1 carbon to nitrogen.

2. Aeration: Turn the pile weekly to incorporate oxygen.

3. Moisture Monitoring: Keep it as damp as a wrung-out sponge.

4. Maturation: After ~8–12 weeks, the compost should look dark and crumbly; fibers should be well-integrated and unrecognizable.

4. Using Hemp Compost

• Soil Amendment: Mix 1–2 inches into garden beds for nutrient-rich topsoil.

• Mulch or Top-Dressing: Spread a thin layer around plants—it suppresses weeds and retains moisture.

• Potting Mix Additive: Combine compost with mineral-rich materials for homemade potting blends.

5. Tips & Best Practices

• Heat the Compost: If hot composting, aim for 130–160 °F to decompose fibers efficiently.

• Balance the Mix: Hemp is mostly carbon—combine it with nitrogen sources to avoid a slow rot.

• Be Patient: Larger fibers decompose slowly; allow extra time for full breakdown.

6. Hemp Fiber vs. Other Mulches

• Unlike wood chips, hemp fibers decompose faster and add usable organic matter.

• Compared to commercial compost, hemp fiber helps build bulk and structure more effectively.

Final Take

Hemp fiber composting turns a byproduct into a valuable resource. It supports soil health, promotes sustainable agriculture, and aligns with eco-conscious practices. Contact Sales@laktownmills.com for pricing on fiber and hurd products.
