How to set up an integrated fish, grass, and pig farming system that produces 250 kg of fish per 0.07 hectares of pond? Based on current data, achieving this target requires approximately 10,000 kg of pig manure and 10,000 kg of base fertilizer. This means a total of 20,000 kg of pig manure is needed for both base and top dressing, which implies that 8 to 10 pigs are required per 0.07 hectares of water surface.
To support the system, about 0.028 hectares of land is needed to grow 6,300 kg of green feed like ryegrass and Sudan grass. Assuming that 70 kg of green feed can be produced from 100 kg of swine manure, then 9,000 kg of pig manure would yield 6,300 kg of feed. If each pig produces around 2,250 kg of manure, then 4 pigs would suffice. Each pig requires about 875 kg of green feed, so four pigs would need 3,500 kg of feed in total, which requires 0.015 hectares of land.
In conclusion, the pig, grass, and fish model that produces 250 kg of fish per 0.07 hectares of pond needs 0.043 hectares of feed area and 4 pigs. By implementing this system, a family can produce around 300 kg of pork and 250 kg of fish annually. This model not only maximizes land use but also promotes sustainable agriculture by recycling nutrients between livestock, crops, and aquaculture. It's a practical approach for small-scale farmers looking to increase productivity while maintaining environmental balance.
