Crab Shell Pellet

Crab shells make an excellent organic fertilizer due to their high calcium content and the presence of chitin. Chitin promotes beneficial soil bacteria that help control fungi and nematodes, while calcium strengthens plants and improves nutrient absorption. Crab shell fertilizer is a slow-release source of nitrogen, phosphorus, and other micronutrients.

Benefits of using crab shell fertilizer

1. Nutrient source: Crab shells provide essential nutrients, including calcium, nitrogen, phosphorus, and magnesium, and other micronutrients.
2. Soil health: The high calcium content improves soil structure and helps plants absorb other nutrients from the soil.
3. Pest and disease control: The chitin in the shells encourages the growth of chitin-eating bacteria, which creates a hostile environment for fungus and root-damaging nematodes.
4. Natural and sustainable: Using crab shells as a fertilizer is an effective way to recycle marine waste and reduce reliance on synthetic fertilizers.

How to use crab shells as fertilizer

1. Process the shells: You can buy crab shell meal or powder, or process your own by washing and drying the shells, then grinding them into a powder or small pieces.
2. Apply to soil: Incorporate the ground shells directly into the soil before planting. A general guideline is to apply about 3 pounds per 100 square feet or 100-200 pounds per acre.
3. Water well: Water the area after application to help the shells begin to break down and release their nutrients into the soil.
4. Integrate into a plan: Crab shell is a slow-release fertilizer, so it works best as a long-term soil amendment. It can be a good addition to your existing fertilizing program.
