Nitrogen Fixer
Pisum sativum. Hardy Annual. This nitrogen fixer tolerates somewhat heavier soils and can be planted slightly later in the fall than crimson clover. Sow seeds 2-8cm (1-3") deep in fairly dense concentration.
Sow Winter Field Peas cover crop seeds from mid-February to the end of May, and again late August to the end of September. Winter Field Peas are hardy to Zone 6: -23°C (-10°F). 500g covers approximately 40m2 (438 ft²).
This cover crop can be mingled with to store even more nitrogen and to add even more organic matter to the soil.

Sow as early as the ground can be worked and repeat until late spring. Sow a fall crop towards the end of summer. This pea is hardy to Zone 6: -23°C (-10°F).
For nitrogen fixation, allow plants to reach the flowering stage. If tilling under, allow two weeks before planting the next crop. Avoid following this cover crop with other legumes, like peas, beans, or soy.
