- Build a compost pile, either in a bin or on the ground, with a mix of “green” (nitrogen-rich) and “brown” (carbon-rich) materials.
- Add the shrimp shell mixture to the compost pile, ensuring it’s well-mixed with other materials.
- Step 3: Maintaining the Compost Pile
- Regularly turn the compost pile to maintain oxygen flow and prevent anaerobic conditions.
- Monitor temperature, aiming for 130°F – 140°F (54°C – 60°C), and adjust the pile as needed.
Anaerobic Fermentation
Anaerobic fermentation involves mixing the ground shrimp shells with water and allowing them to break down in the absence of oxygen.
- Step 1: Creating the Fermentation Mixture
- Mix 1 part shrimp shell powder with 10 parts water.
- Stir well to create a uniform solution.
- Step 2: Fermenting the Mixture
- Transfer the mixture to an airtight container, such as a bucket or barrel.
- Seal the container, ensuring it’s free from oxygen.
- Allow the mixture to ferment for 2-4 weeks, stirring occasionally.
Harvesting and Using Shrimp Shell Fertilizer
Once the composting or fermentation process is complete, it’s time to harvest and use your shrimp shell fertilizer.
Compost Tea
- If you’ve used the aerobic composting method, you can create a compost tea by steeping the finished compost in water.
- Strain the liquid and use it as a foliar spray or add it to the soil.
Fermentation Liquid
- If you’ve used the anaerobic fermentation method, you can use the resulting liquid fertilizer directly.
- Dilute the liquid with water, following a 1:10 ratio, and apply it to the soil.
Shrimp Shell Meal
- If you prefer a solid fertilizer, you can dry the fermented mixture or compost to create a shrimp shell meal.
- Use this meal as a slow-release fertilizer, mixing it into the soil or using it as a top dressing.
