Turning Straw into Organic Fertilizer – ECO BLUE: An Effective Solution for the Rice-Shrimp Farming Model

The rice–shrimp rotational (or integrated) farming model is a widely adopted sustainable agricultural practice in the Mekong Delta, particularly in the provinces of Bac Lieu, Ca Mau, Soc Trang, and Kien Giang. This model alternates between the saline water season and the freshwater season, making the most of natural conditions, reducing investment costs, and minimizing pollution and disease risks.

However, after each rice crop, the leftover straw and stubble at the bottom of the pond become a major problem for farmers. If not thoroughly treated, the straw will decompose anaerobically, releasing toxic gases such as H₂S and NH₃, which pollute the pond water and directly affect the health of the shrimp—causing them to float to the surface, grow slowly, and develop bent bodies and muscle opacity. Traditional treatment methods such as burning, manual removal, or leaving it to decompose naturally often require a lot of labor and time, yet are not completely effective.

How can rice straw be quickly and effectively treated while also turning it into a beneficial source of organic fertilizer for shrimp ponds?

ECO BLUE Probiotic – A Modern Biological Solution for Shrimp-Rice Farming Ponds

After many years of research and field application in shrimp farming areas, Mỹ Bình's ECO BLUE probiotic product has proven to be highly effective in integrated or rotational shrimp-rice farming systems. It is capable of breaking down rice straw within just 7 days while significantly improving the quality of the pond environment.

Mechanism of Action of ECO BLUE

ECO BLUE is a powerful microbial decomposer containing high-activity Bacillus spp. strains, combined with beneficial fungal spores that can:

• Survive in both anaerobic and aerobic environments, even under low pH, low oxygen levels, polluted conditions, and in the presence of toxic gases.
• Rapidly break down cellulose and lignin – the two main components of straw structure – accelerating the decomposition process, converting it into easily absorbable organic matter that enriches the soil and supports natural food sources for shrimp such as tubifex worms and rice snails.
• Transform organic waste (shrimp feces, leftover feed, and dead algae) into beneficial nutrients that support the growth of useful microorganisms in the pond.

7 Days – Turn Rice Straw into Organic Fertilizer for Shrimp Ponds

The results of using ECO BLUE to decompose rice straw in a rice–shrimp farming model show that:

• After applying ECO BLUE directly on the pond surface with rice straw, within just 7 days, the straw softens and nearly completely decomposes.
• The black bottom mud turns light brown and emits no foul odor.
• The water becomes clear and tea-colored, with no toxic gases.
• Shrimp can be stocked just 7–10 days after pond treatment with ECO BLUE.

Specific Benefits of Using ECO BLUE in Shrimp Ponds

• Rapid decomposition of straw and organic sludge within just 7 days
• Converts straw into organic fertilizer, creating a natural nutrient source for beneficial algae
• Stabilizes pH levels and reduces toxic gases such as H₂S and NH₃ in the pond
• Improves water clarity and limits eutrophication
• Cleaner pond bottom, with firmer and more compact soil, helping to better control disease
• Promotes faster shrimp growth and reduces losses caused by hepatopancreatic disease and white feces syndrome

Instructions for Proper Use of ECO BLUE to Achieve Optimal Results

To maximize the effectiveness of the ECO BLUE probiotic, farmers are advised to follow the guidelines below:

1. For earthen ponds (traditional shrimp farming)
• Dosage: Use 250g per 3,000m³ of pond water, applied every 5–7 days.

2. For integrated rice–shrimp farming (extensive farming)
• Dosage: Use 1kg per 1 hectare of water surface, applied every 5–7 days.
• Special note: After each rice harvest, it is recommended to apply ECO BLUE early while the straw is still moist to take advantage of natural humidity, which accelerates the decomposition process.

Notes:
• It is best to continue applying ECO BLUE consistently for 2–3 weeks after the rice harvest to thoroughly break down leftover straw.
• Avoid using disinfectants, sterilizing agents, or quicklime together with ECO BLUE within a 48-hour window.

If you're struggling with rice straw polluting your pond water and affecting your shrimp farming, ECO BLUE is the modern biological probiotic solution you need.
With the ability to decompose rice straw in just 7 days, ECO BLUE not only protects the pond environment but also transforms waste into valuable organic fertilizer. This product is highly rated by many shrimp farmers.
