53: How To Make Any Soil Amazing With Cover Crops: Grow Your Own Fertility! | JM Fortier

In this solo episode, Jean-Martin Fortier reveals the ultimate secret weapon for healthy soil and high-yield market gardening: cover crops and green manures. While beginner market gardens often focus strictly on profitable cash crops, long-term farm sustainability and profitability depend on embedding cover crop systems directly into seasonal crop rotations.

Jean-Martin explains how standard cover crops eliminate erosion by protecting bare winter soils, while legume-rich green manures supercharge on-farm fertility by injecting nitrogen and building massive subsoil root networks. He breaks down his practical, low-machinery techniques for terminating cover crops on permanent beds and you’ll discover how hitting the "golden ratio" of keeping one-third of your garden in cover crop at all times can drastically reduce external fertilizer inputs and unlock deep, long-term soil ecology.
