Shrimp farmers should be aware of how to make liquid organic fertilizer. Fertilizers help boost plankton growth, which is beneficial for cultivation. Making organic fertilizer is also cheaper than purchasing inorganic ones. Organic fertilizers can be made by mixing organic materials with mineral nutrients. Learn 2 ways to make liquid organic fertilizer for shrimp farms in this article!
How to Make Simple Liquid Organic Fertilizer
The first way to make liquid organic fertilizer can be done with fewer ingredients. Hence, it is suitable for farmers who want to make fertilizers at less cost. Here are the ingredients:
- 1 kg of bran
- 100 g of ZA fertilizer
- 4 ml of MSG 3
- 100 ml of aquaculture EM4
- 3 tbsp of instant yeast
- 100 ml of molasses
- Sterilized water as needed
Follow these steps to make the simple liquid organic fertilizer:
- Mix all the ingredients in a covered container.
- Let it sit for 48 hours.
- After 48 hours, filter the liquid fertilizer and dispose the residue. The liquid organic fertilizer is ready to be used.
The dosage above is suitable for one-time stocking. Adjust the amount of ingredients based on the desired usage.
How to Make Enhanced Liquid Organic Fertilizer
Aside from the first way, you can also make liquid organic fertilizer with this second method. This method requires more ingredients and is suitable for those of you who want to add more nutrients into your pond. Here are the ingredients you need to prepare:
- 500 grams of high-protein shrimp pellets
- 500 grams of mung bean sprouts
- 500 grams of pineapple with skin
- 500 grams of banana stems, trunks, and fruit
- 25 grams of tapai yeast
- 250 grams of fish meal
- 2 liters of coconut water
- 1.2 liters of rice wash water
- 250 ml of aquaculture EM4
- 300 ml of molasses
Follow these steps to make enhanced liquid organic fertilizer:
- Blend pellets, sprouts, pineapple, bananas, and fish meal in a blender. Add water if needed for a smoother blending process.
- Transfer the blended mixture to a gallon or container.
- Add coconut water, rice wash water, and plain water until the total liquid reaches 10 liters.
- Add molasses and yeast, then stir until dissolved.
- Add EM4, stir, and cover the container.
- Let it ferment anaerobically for 3 days.
- The liquid organic fertilizer is ready to be applied.
How to Apply Liquid Organic Fertilizer in the Pond
Liquid organic fertilizers help in supporting plankton growth, which functions as a natural food source and a light buffer in shrimp ponds. In addition, the use of EM4 in the fertilizer adds probiotics or beneficial microorganisms to the pond, helping to reduce the population of pathogenic bacteria and improve water quality.
Since liquid fertilizers quickly release their nutrient content, shrimp farmers need to apply it regularly at certain intervals and monitor water clarity as an indicator of adequate plankton population in the pond.
Apply the liquid organic fertilizer once a week in the morning with a dosage gradually increased, starting from 2 liters/ha in the first month, 4 liters/ha in the second month, and 8 liters/ha in the third month. Dilute the measured fertilizer with water from the tank and pour it into the pond. Store the remaining fertilizer in a shaded place away from direct sunlight. Stop applying the fertilizer when the pond water reaches a sufficiently brownish green color.
Conclusion
Liquid organic fertilizers can be made by mixing organic materials and mineral nutrients. This type of fertilizer supports plankton growth in the farm.
When applying fertilizers in pond water, it is important to keep monitoring water quality.
