Old Cobblers Farm™ Wicked Organics Feather Meal

High-Nitrogen, Slow-Release Organic Fertilizer

Give your garden the boost it needs with Wicked Organics Feather Meal, a rich, slow-release nitrogen fertilizer made from hydrolyzed and ground poultry feathers. With a typical nitrogen content around 12–13% N, this feather meal is one of the most concentrated organic nitrogen sources available—perfect for heavy feeding crops such as corn, leafy greens, brassicas, garlic, and turfgrass. If you’ve searched for phrases like “organic fertilizer for leafy greens,” “slow-release nitrogen source for long-season crops,” or “best fertilizer for heavy feeders without burning,” this is the solution you want.

Nutrient Profile & How It Releases

High nitrogen (12-13%) — mostly in water-insoluble (slow-release) form from the keratin proteins in feathers. 

Very low phosphorus and potassium (often <1%) — makes it ideal when you want nitrogen strength without pushing other nutrients too aggressively. 

Interacts with soil microbes: feather meal must be mixed into soil and warmed/moistened so organisms can break it down (mineralization). 

Key Benefits You’ll See

Steady foliage and green-up — perfect for vegetables and leafy greens that need sustained nitrogen rather than bursts of growth.

Low risk of burning plants — because nutrients are released gradually, there’s less chance of foliage burn even in sensitive crops.

Supports soil life — the organic protein meals feed microbes, fungi, and beneficial soil organisms; improves soil structure and fertility over time.

Long-term feeding period — feather meal provides nitrogen over several weeks to months, depending on soil temperature, moisture, and microbial activity. 

Best Uses & Application Guidelines

Vegetable or Annual Garden Beds

Mix 5–8 lbs per 100 sq ft into topsoil before planting.

Especially effective for heavy nitrogen feeders like corn, kale, and broccoli.

Side-Dressing Established Plants

Apply about ½ cup per plant along the row every 4–6 weeks during active growth.

Supports steady leaf and shoot production throughout the season.

Lawns / Turfgrass

Spread 10–15 lbs per 1,000 sq ft in spring and/or fall.

Improves color, density, and recovery—ideal after stress, damage, or high traffic.

Trees & Shrubs

Broadcast 1–2 lbs per inch of trunk diameter under the dripline.

Water in thoroughly and, if possible, lightly mix into the soil for better nutrient uptake.

Always water in after applying; moisture helps soil organisms begin mineralizing the nitrogen.

Best applied when soils are warm and moist (microbes active) to maximize release speed.

Using in cool, dry soil will slow down nitrogen release.

Combine with phosphorus or potassium sources if soil tests show deficits in those nutrients.

Ideal Crops & Plants for Feather Meal Usage

Heavy feeders: corn, cabbage, kale, broccoli, leafy greens

Garlic, onions, and other alliums that need nitrogen for bulb/leaf development

Turf and lawns needing greener color and recovery from wear or drought

Vegetables and annuals where slow, sustained growth is preferred over fast flushes of foliage

Soil building and compost enrichment for long-term fertility

Why Wicked Organics Feather Meal is a Smart Choice

Concentrated organic nitrogen means you use less volume to get strong results.

Slow, stable release helps avoid nutrient wash-out and the problems of synthetic fertilizers.

Helps improve soil biology, structure, and long-term fertility rather than only pushing instant growth.

Safe for organic, food-crop gardens, and especially useful where frequent fertilization is impractical.
