Economical Biofertilizer for Farmer Groups: Application Schedule per Growth Phase

Economical biofertilizer is the right solution for farmer groups who want to increase land productivity without burdening the budget. By utilizing superior microorganisms such as Bacillus subtilis, Azotobacter sp., and Trichoderma sp., the Economical Biofertilizer Formula Assistance Program from Biosolution is designed to support subsidy programs and farmer empowerment. This article presents the application schedule per growth phase for maximum results.

Why is Economical Biofertilizer Important for Farmer Groups?

Farmer groups often face high production cost challenges, especially for purchasing chemical fertilizers. Economical biofertilizer offers a cheaper and environmentally friendly alternative. This product contains Bacillus subtilis bacteria that act as PGPR (Plant Growth Promoting Rhizobacteria) as well as phosphate solubilizers, Azotobacter sp. as a non-symbiotic nitrogen fixer, and Trichoderma sp. as a biocontrol agent for soil pathogens. With regular application, soil fertility increases and dependence on subsidized fertilizers decreases.

Furthermore, economical biofertilizer is easy to socialize to farmer group members because the application method is simple: just drench the roots or spray the soil at a dose of 10 ml per liter of water every 14 days. This product is also compatible with local compost, so farmers can utilize organic materials available around them.

Preparation for Economical Biofertilizer Application

Required Tools and Materials

• Economical Biofertilizer Formula (1 liter bottle)
• Clean water (non-chlorinated)
• Bucket or spray tank
• Stirring tool
• Gloves (optional)

Preparation Steps

1. Calculate the required solution volume: for 1 hectare of land, approximately 200-400 liters of solution is needed (10 ml product per liter of water).
2. Fill the spray tank halfway with water.
3. Add the product according to the dose, stir well.
4. Add water to the desired volume, stir again.
5. Apply immediately after mixing to maintain microbial viability.

Application Schedule per Growth Phase

Pre-Planting Phase (7 Days Before Planting)

In this phase, the application of economical biofertilizer aims to colonize the rhizosphere with superior microbes. Trichoderma sp. will suppress soil pathogens such as Fusarium and Rhizoctonia, while Bacillus subtilis begins to solubilize bound phosphate. Application is done by drenching the soil in the root zone. Dose: 10 ml/liter, volume 200 ml per planting hole. If using a spray system, spray evenly onto the soil surface.

Early Vegetative Phase (7-14 DAP)

After seedlings are planted, the second application is done at 7-14 days after planting (DAP). In this phase, Azotobacter sp. begins actively fixing nitrogen from the air, providing N for plants. Bacillus subtilis also produces phytohormones such as auxins and gibberellins that stimulate root and shoot growth. Apply by drenching or spraying the soil around the root zone.

Late Vegetative Phase (21-28 DAP)

The third application in this phase strengthens vegetative growth. Microbes continue to provide nutrients and protect plants from pathogen attacks. If there are signs of fungal attack, Trichoderma sp. will act as a natural biocontrol. Dose remains 10 ml/liter, interval 14 days.

Generative Phase (35-42 DAP)

Entering the flowering and fruiting phase, economical biofertilizer application helps plants maintain vigor. Phosphate available from Bacillus subtilis activity is crucial for flower and fruit formation. The fifth application at 35-42 DAP.

Fruit Filling Phase (49-56 DAP)

The final application in the fruit filling phase ensures plants remain healthy until harvest. Azotobacter sp. still supplies nitrogen, while Trichoderma sp. protects roots from infection. As a result, harvest quality and quantity increase.

Tips for Successful Economical Biofertilizer Application

• Application time: Morning or evening to avoid UV rays that can damage microbes.
• Water quality: Use chlorine-free water; if using well water, let it sit overnight so chlorine evaporates.
• Combination with compost: Mix the product with local compost to increase microbial population and soil organic matter.
• Storage: Store the product in a cool, dark place, away from direct sunlight.
• Monitoring: Observe plant growth and soil conditions; if necessary, adjust dose or interval.

Economic Benefits for Farmer Groups

By using economical biofertilizer, farmer groups can save up to 30-50% on chemical fertilizer costs. This product also supports government subsidy programs because it is affordable and easy to distribute. Additionally, the simple application facilitates socialization to farmer group members. Healthier and more environmentally friendly harvests also increase the market value of agricultural products.

Conclusion

Economical biofertilizer for farmer groups is a smart solution to increase land productivity at low cost. By following the correct application schedule per growth phase, farmers can maximize the benefits of Bacillus subtilis, Azotobacter sp., and Trichoderma sp.. This product is highly suitable for assistance programs and cooperatives.
