Using Alfalfa as Green Manure for Lawn Preparation in Nevada

Planting alfalfa as a green manure cover crop to improve clay soil in Elko, NV before seeding a lawn? Here's the practical process.

The Process: Grow, Mow, Incorporate

1. Seed alfalfa at a high rate in spring.
2. Allow 7–10 weeks of growth—this builds organic matter and loosens clay.
3. Rototill the vegetation into the soil.
4. Irrigate and add a light nitrogen application to speed decomposition.
5. Level the area and seed your climate-adapted lawn grass.

Why This Works

Alfalfa's deep taproots (12–15 ft) mine nutrients from subsoil. As a legume, it fixes atmospheric nitrogen. Tilling it in before flowering prevents reseeding in your future lawn.

No special alfalfa variety needed. Just manage the mowing timeline strictly—no flowers, no seeds, no volunteers.
