High nitrogen and organic matter yields, chokes weeds, attracts beneficials
Extraordinary yields of Nitrogen (up to 290 lb/acre) and organic matter (up to 49 tons/acre). Chokes out weeds and provides excellent habitat for beneficial insects. Peaceful Valley developed this mix especially for vegetable rotations and general cool-weather cover cropping. Soil Builder is not filled with cheap grasses like other mixes. Contains the highest-yielding winter-hardy legumes with cayuse oats added to stabilize the soil, and to nurse and scaffold the vetches. Grows to 4'-6'. Seed at 3-5 lb/1000 sq ft, or 70-120 lb/acre at a depth of 3/4 to 1 in September or October. In coastal or cool summer zones, Soil Builder can be spring-planted.
Raw seed, requires Pea Vetch or Garden Combination Inoculant. Formulation may vary based on availability. Currently the mix contains: Bell Beans, BioMaster Winter Peas, Arvika peas, Purple Vetch, Common Vetch and Cayuse Oats.
Organic Premium Soil Builder Mix
Cool Season Annual Cover Crops are planted in fall to protect the soil over the winter and produce an abundance of organic matter in spring.
- Ease of Growing
- Grown as
- Days to Maturity
- 90-180 (Fall/Winter)
- Growing Habit
This is a fairly hardy mix, designed to keep growing right through mild winters.
- Growing Season
- Short, Long
- Cultivar Type
- Growing Conditions
- Cold, Cool
These cover crops generally require cooler temperatures and adequate water.
- Outdoor Growing Temp
- 40°F - 85°F
- Min Outdoor Soil Temp
Most cool weather cover crop should be started when temperatures are still in the 60's to allow the plants to establish before winter, which also prevents Winterkill.
- Start Indoors
- Start Outdoors
- Sun: min. 6 hours daily (Cold, Cool)
Cover crops need full sun when growing in winter, as days are shorter and the sun is lower in the sky. If grown in summer many will tolerate light shade (though they grow best in full sun).
Most of these crops are not particularly drought tolerant and will need regular watering in dry climates (especially when germinating and getting established). However they are mostly grown during the winter when the soil is fairly moist, so don't usually require much irrigation.
You do not need to fertilize cover crop in established gardens, as there will be plenty of nutrients in the garden to meet their needs. Since you will be incorporating them back in to the soil, growing them doesn't remove any nutrients from the soil.
The leguminous cover crops also fix nitrogen and eventually add it to the soil.
