Sustainable Rice Production: Advancing Precision Agriculture in the Mekong Delta

The agricultural landscape of Vietnam’s Mekong Delta is undergoing a significant transformation. By shifting from a production model focused solely on high yields to one centered on efficiency, quality and low emissions, local farmers are setting a new standard for sustainable rice cultivation. At the heart of this transition is the integration of digital tools, precision machinery, and standardized technical procedures designed to improve long-term profitability and environmental health.

The Shift Toward Precision Fertilization

Efficient nutrient management is a critical component of modern rice farming. Traditional methods often lead to excessive fertilizer use, which increases production costs and contributes to greenhouse gas emissions. To address these challenges, the Department of Agriculture and Rural Development of Can Tho City, in coordination with the International Rice Research Institute (IRRI) and various agricultural enterprises, has launched initiatives to implement precision fertilization models.

These models focus on the “four rights” of fertilization: the right type, the right dose, the right timing, and the right method of application. By utilizing digital resources such as the Rice Crop Manager (RCM) application, farmers can now make data-driven decisions regarding nutrient needs. This technology, combined with the use of agricultural drones and precision machinery, allows for a more targeted approach that minimizes waste and reduces labor requirements.

Key Benefits of the New Approach

• Cost Reduction: Precision application and mechanical placement of fertilizers can reduce production costs by 20% to 30%.
• Environmental Impact: Optimized practices contribute to a measurable reduction in greenhouse gas emissions per hectare.
• Economic Efficiency: Farmers have reported significant increases in profit margins per hectare by reducing input waste.
• Technological Adoption: The use of digital tools and mechanization facilitates a more professional and standardized production process.

Implementing Large-Scale Sustainability

The current initiative is part of a broader effort to cultivate one million hectares of high-quality, low-emission rice across the Mekong Delta by 2030. In Can Tho City alone, the project spans dozens of districts and communes, involving hundreds of cooperatives and cooperative groups. The strategy emphasizes the “1 Must, 5 Reductions” principle, which includes the use of certified seeds, controlled sowing densities, and the Alternate Wetting and Drying (AWD) irrigation method.

According to experts at the IRRI, these complementary technologies—such as mechanical row seeding with simultaneous fertilizer burial—are essential for maintaining or increasing yields while lowering the environmental footprint of the industry. This shift is viewed as an inevitable evolution for the region to remain competitive and ensure sustainable livelihoods for rice producers.

Future Outlook

The success of pilot programs in cooperatives such as the Kien Thanh Agricultural and Service Cooperative demonstrates the practical viability of these advanced agricultural solutions. By fostering coordination between international organizations, local government departments, and the private sector, the region is building a robust foundation for digital transformation in agriculture.

As these models continue to scale, the focus remains on providing farmers with the training and equipment necessary to transition to high-quality production. This commitment to innovation not only bolsters the local economy but also aligns the Mekong Delta’s rice industry with global standards for environmental stewardship and green growth.

Frequently Asked Questions

What is the “1 Must, 5 Reductions” principle?

It is a technical framework for sustainable rice farming. The “1 Must” refers to the use of certified, high-quality seeds, while the “5 Reductions” focus on minimizing seed rate, fertilizer use, pesticide application, water usage, and post-harvest losses.

How do agricultural drones help with fertilization?

Drones allow for the precise, aerial application of fertilizers, ensuring even coverage across the field. This method reduces the physical labor required for manual spreading and minimizes the risk of over-fertilization in specific areas.

What is the role of the Rice Crop Manager (RCM)?

RCM is a digital tool that provides farmers with customized management recommendations. By inputting specific field conditions, farmers receive guidance on how to optimize fertilizer and water use for their particular soil and crop stage.
