Old Cobblers Farm™ Wicked Organics Soy Bean Meal

Natural Slow-Release Nitrogen Fertilizer

Power up your garden with Wicked Organics Soy Bean Meal, a plant-based, slow-release nitrogen source made from finely ground, de-oiled soybean seeds. Designed especially for organic gardeners who want strong green growth without the harshness of synthetic fertilizers. If you’ve searched for “organic nitrogen fertilizer for leafy greens,” “soybean meal for vegetable gardens,” or “vegan fertilizer for lawns and plants,” this is what you’ve been

looking for.

What Makes It Effective

Offers about 7-8% total nitrogen, typical of high quality soybean meal fertilizers. Because the nitrogen is bound in organic proteins, it becomes available gradually as soil microbes break it down. This makes it much safer and more forgiving than quick-release synthetic N sources. 

Also contains small amounts of phosphorus and potassium (often around 1-2%) and trace minerals, which makes it more of a balanced plant food than pure nitrogen by itself. 

Key Benefits You’ll Notice

Steady, sustained foliage growth in vegetables, leafy greens, corn, brassicas (broccoli, kale, cabbage) without risk of burning or shocking.

Improves soil biology — feeding beneficial microbes which help break down organic matter, release nutrients over time, and improve soil texture.

Very low risk of nutrient leaching because the nitrogen release is gradual. Ideal for organic gardens and ecological soil health.

Works well as a replacement for animal-based nitrogen meals if you want vegan or non-animal fertilizer inputs.

Best Uses & Application Guide

Vegetable Gardens

Rate & Timing: Mix 5–7 lbs per 100 sq ft into the top 2–4 inches of soil before planting to support heavy feeders.

Side-Dressing Established Plants

Rate & Timing: Apply ½ cup per plant, especially for corn, brassicas, and leafy greens. Reapply every 4–6 weeks if needed.

Lawns / Turf

Rate & Timing: Spread 10–15 lbs per 1,000 sq ft in spring and fall for quick green-up and recovery, ideal for organic lawn care.

Trees & Shrubs

Rate & Timing: Broadcast under the dripline, using 1–2 lbs per inch of trunk diameter. Lightly work into soil around roots.
Water in after applying to help the microbes get active and begin nutrient mineralization.

Avoid applying very close to seed germination of delicate small seeds; let the soil microbial activity start first, else you may suppress germination. NC State Extension notes that soybean meal can reduce germination of some small seeds if placed too heavily or directly on seed beds. 

Ideal Crops & Situations

Leafy greens: lettuce, spinach, chard, kale

Brassicas: cabbage, broccoli, cauliflower

Corn, sweet corn, other high-nitrogen crops

Lawns / turf applications where greener color and recovery is desired

Orchards or fruit trees when you want vegetative growth early in season
