Best Organic Feather Meal (12-0-0): Slow-Release Nitrogen That Feeds for 4–8 Weeks Without Burn Buy on Old Cobblers Farm
Old Cobblers Farm™ Wicked Organics Feather Meal
by Wicked Organics — Littleton, NH
4–8 Week Slow Release
Keratin protein in feathers takes longer for soil microbes to break down than blood protein. This natural resistance creates a 4–8 week sustained nitrogen release — no surge, no crash.
12% Organic Nitrogen
Same nitrogen concentration as blood meal, but with a fundamentally different release profile. The patient organic N source for growers who plan ahead.
Apply Before Planting
Mix into soil 2–4 weeks before planting to give microbes time to begin keratin breakdown. By the time seedlings go in, nitrogen is actively releasing.
Zero Burn Risk
The slow microbial release of feather meal means virtually no burn risk, even at higher application rates. Safe for direct soil contact near seeds and young roots.
85–170 sq ft Per Bag
At 3–6 lbs per 100 sq ft, one 5 lb bag covers a standard garden bed. Higher rates for heavy-feeding crops like corn and brassicas.
Field-Scale Organic N
At 25–50 lbs per 1,000 sq ft, feather meal is a viable field-scale organic nitrogen source for market gardens, small farms, and organic crop production.
Organic Approved
Hydrolyzed poultry feather meal is an approved organic input for NOP-compliant farms and gardens. A sustainable byproduct of the poultry industry.
