After beans or peas: lighten the N fixation pitch
Oats, rye, buckwheat, or shallow-rooted greens — not another heavy legume stand
Nutrients & rotation
Legumes already fed the soil biologically; the next cover is often about **biomass, weed cover, or catching excess nutrients**, not stacking redundant clover on clover every single year.
Rotation memory: after peas, a grass or buckwheat can scavenge N and prep a clean seedbed for fall brassicas or garlic.
In the garden
- If you still want clover, use it on another bed that hosted heavy feeders last season.
- Oats + field pea mix can still work after beans if your goal is erosion control on a slope — goals over dogma.
Timing
Immediately after legume harvest while soil is still warm and weeds are eager.
