Horizon forage pea is an annual legume, valued as a high nitrogen fixer, weed suppressor and forage that creates a high root mass, adding organic matter to the soil. It is also an excellent soil improver, and good for erosion control, weed suppression and grazing choice.
Lightly broadcast seeds and work into the top half inch of moist soil, or cover with 1/2 inch of mulch or compost. Water to equivalent of 1 inch of rainfall per week until seedlings become established. Do not fertilize as this delays the nitrogen fixing action of the legumes.
Planting rates -
8 oz will seed approximately 200 sq. feet
1 lb will seed approximately 400 sq. feet
Horizon is a high nitrogen fixer with abundant vining forage with an extensive, fast-growing root system that helps short-term soil improvement. Forage peas grow rapidly as the weather cools down from late summer into fall and early winter.
It produces an abundant root and stem biomass that breaks down quickly, adding organic matter and carbon content both above and below the soil surface. Because of the rapid decomposition, forage peas are not used as a primary means of weed control, but supplement other cover crops in soil improvement which deters weed seed germination.
The Horizon forage pea is a Canadian strain which often outgrows several other varieties of winter and spring field peas. Forage and field peas are one of the top nitrogen sources, both from its fixing action from the air and the recycling of mineral nitrogen excess in the soil which is taken up by the plant and made available the next spring from decomposition of the roots and stems.
Forage peas are very moisture efficient in producing organic matter, needing much less water than other cover crops. They provide excellent soil disease suppression, improved soil structure and moisture management as well as increasing soil fertility throughout the next season. They help boost the protein content and forage yield of other cover crops when grown together.
The purple and white blossoms are an early and extended source of nectar for many bee species, especially honey bees as well as many other pollinators.
Horizon peas are usually fall planted in September through mid-October in milder winter areas. Peas will germinate and grow through lower temperatures than most crops, so a hard frost is needed to kill them. In areas of warmer winters, mowing or weed whacking after full bloom is needed to kill the peas. Waiting until after the full bloom happens, but before the seed pods are developed will provide the most nitrogen to the soil.
