Farm Seed at a Glance
Does viewing this table on a small screen make you want to cry? We have wracked our brains and have not yet come up with a satisfactory way to display all of this tabular data on mobile devices. Perhaps you can use a device with a larger screen, or can download and print a copy of the table: (PDF).

Key
Best Uses:- bees: provides bee forage for honey production
- feed: produces a grain or bean suitable for animal consumption
- food: produces a grain or bean suitable for human consumption
- erosion control: roots hold soil well
- hay: maintains nutritional quality when dried
- lawn: suitable for heavy traffic areas, withstands mowing
- N-fix: green manure fixes nitrogen, available to subsequent crops when tilled into soil
- organic matter: soil builder green manure, produces biomass and improves soil structure
- pasture: superior nutrition and yield, withstands grazing
- pest control: reduces insect, disease, or nematode pressure
- scavenger: quickly takes up nutrients from soil, preventing their loss to erosion or leaching
- weed control: physically out-competes or chemically inhibits weeds
3Seeding rates are based on drilled seed in organically managed fields. Seeding rates vary depending on crop use, timeliness of planting, method of seeding, weed pressure, soil conditions, seed size, and whether the crop is planted alone or in a mix. If you need help figuring out what seeding rate to use, please give us a call.
- For most seed, use the smaller amount in mixes and the larger amount solo.
- For corn, use the smaller amount for grain and the larger amount for silage.
- For broadcasting, increase 20-25%.
- For use in precision planters, decrease 10-50%.
- For late planting, increase 20-50%.
- For forage or weed control uses, increase 30-50%.
4Nitrogen-fixing bacteria reside on the roots of legumes. Use inoculant to ensure populations. Y means yes, fixes N, but no info on quantity available. Some rhizobial bacteria form symbiotic relationships specifically with the roots of leguminous crops; these bacteria convert atmospheric nitrogen (which is unavailable to plants) to ammonia and nitrates (which are available to plants). Legumes can often furnish nearly all of their own nitrogen needs this way—exactly how much depends on the species, the soil structure, and weather conditions. If the crop is removed from the field, the fixed nitrogen is removed as well, with little or no residual added nitrogen remaining in the soil; however, if the crop is turned in and incorporated into the soil, the fixed nitrogen is added to the soil and is available in slow-release forms to the following crop. Therefore, quantities of nitrogen fixed are listed only for those crops used as cover crops, and these quantities should not be interpreted as absolute numbers but as indications of a species’ relative efficiency at fixing atmospheric nitrogen.
5Biomass, or Organic Matter: Succulent biomass makes a rapid contribution to available soil nutrients. Fibrous biomass helps build humus, which improves soil texture and increases nutrient-holding capacity.
