Earthworm farming can be carried out once the basic habits and breeding patterns are understood. The specific techniques vary depending on the purpose and scale of cultivation. In general, earthworm farming is divided into two main types: outdoor and indoor methods. Indoor farming includes pot culture, basket culture, and other similar techniques, while outdoor methods encompass pond culture, trench culture, composting, swamp culture, garbage absorption fields, garden and farmland culture, ground greenhouses, semi-basement systems, civil defense shelters, plastic greenhouses, and ventilation and humidification techniques. Although the containers and locations differ, the core principle remains scientific management.
Pot culture is ideal for small-scale operations due to its simplicity, ease of maintenance, mobility, and control over temperature and humidity. It is especially suitable for scientific experiments. Pots or containers that are not traditionally used for planting can also be employed. However, it is best suited for species that are small in size and difficult to escape, such as certain types of earthworms. Larger species like Cyclopus maggots may not thrive in this method due to their tendency to escape. The amount of feed placed in the pot should not exceed three-quarters of the container’s depth. Due to the limited volume, the environment inside the pot can fluctuate quickly, making it important to maintain proper moisture and temperature through covering with materials like plastic film or straw and regular watering. It is crucial to avoid using containers that have previously held chemicals or pesticides, as they can be harmful to the worms.
Box and basket culture is another popular method, often utilizing discarded boxes, wicker baskets, or bamboo containers. These should be free from harmful substances like aromatic resins, tannins, and chemical residues. The dimensions of the boxes are typically manageable, with sizes such as 50 cm x 35 cm x 15 cm being common. Drainage and ventilation holes are essential to prevent waterlogging and ensure air circulation. These holes help regulate internal temperatures and allow for the natural separation of worm castings. For larger-scale operations, multi-layered breeding beds can be constructed, optimizing space and increasing yield. Proper spacing between layers ensures good airflow, and a passageway of about 1.5 meters is necessary for easy access.
In winter, maintaining a stable temperature is vital. Heating solutions like solar energy, waste steam, or heating units can be used. Adequate lighting is also important to prevent escape. Equipment such as thermometers, sprayers, and mesh screens are essential for efficient management.
Semi-subterranean greenhouses, civil defense shelters, or caves offer unique advantages, as they naturally maintain stable temperatures and humidity levels. These structures require additional lighting but can be highly effective when properly managed. Similarly, ground greenhouses and shed-based systems provide flexibility, allowing for integration with existing agricultural practices.
Ventilation and humidification techniques are particularly useful in deep soil or feed layers, where oxygen levels can become low. Underground pipes can deliver air to the soil, preventing anaerobic conditions that are harmful to earthworms. Maintaining a moist environment is crucial, as earthworms rely on moisture for respiration.
Farm land culture combines both indoor and outdoor methods, offering cost-effective solutions. By rotating crops and managing environmental factors, farmers can maximize productivity. However, care must be taken to avoid chemical exposure, which can harm earthworm populations.
Overall, regardless of the method used, protecting earthworms from predators and diseases is essential for successful farming. Each technique has its own set of benefits and challenges, and choosing the right approach depends on available resources, climate, and farming goals. With proper planning and management, earthworm farming can be a sustainable and profitable practice.
