Geoff explains why even nitrogen-rich green mulch is usually better cut and laid on the surface, where roots can decompose in place and feed the soil.
This video is taken from Geoff’s Online Permaculture Design Course, which includes weekly Q&A sessions where he answers student questions. Learn more about Geoff’s courses at: discoverpermaculture.com
Key Takeaways:
- 00:00:04 - 00:00:37: Alonzo asks whether nitrogen-rich green mulch can be tilled in without causing the problems associated with nitrogen lock-up.
- 00:00:37 - 00:01:53: Geoff explains legumes store nitrogen in leaves, flowers, stems, seed pods, roots and rhizobium nodules; surface decomposition lets fertility move downward with water.
- 00:01:53 - 00:03:12: Leaving roots in place preserves natural dendritic root patterns as compost-rich corridors; tillage breaks a structure no machine can imitate.
- 00:03:12 - 00:04:15: Chop-and-drop speeds succession without disturbing the underground system, feeding soil from both above and below.

About Geoff:
Geoff is a world-renowned permaculture consultant, designer and teacher who has established demonstration sites in many of the world’s major climates. He’s dedicated his life to sharing permaculture design and inspiring people to care for the earth, care for each other and return the surplus.
About Permaculture:
Permaculture weaves land, resources, people and the environment into a single, supportive system. It mirrors how nature works—no waste, no shortcuts, just smart relationships. The tools are wide-ranging: water harvesting, soil building, energy systems, forestry, natural building, aquaculture, appropriate technology, community development and more. Whether you’re on acreage or in an apartment, these principles scale beautifully.
