Smart Fertigation and Irrigation Project for Vegetable and Rice Farms in Vietnam

Project Overview

To support more efficient crop production in Southeast Asia, a digital agriculture pilot project was designed for a 120-mu equivalent demonstration farm in the Mekong Delta, Vietnam, serving both leafy vegetable cultivation and rice production.

The Mekong Delta is one of Vietnam’s most important agricultural regions, where rice remains a backbone crop and vegetable farming continues to expand, including leafy greens such as mustard greens.

The project introduced an integrated smart fertigation and irrigation system featuring:

Water source management
Filtration and purification
Automated fertilizer dosing
Field drip irrigation and irrigation pipe networks
LoRa-based wireless irrigation control
Intelligent irrigation scheduling

The solution was designed to help growers achieve:

Water Saving + Fertilizer Saving + Labor Reduction + Better Crop Management

Challenges in Vegetable and Rice Farm Irrigation

Upgrading Traditional Vegetable and Rice Irrigation

Leafy vegetables and rice require careful water and nutrient management, but conventional farming methods often rely heavily on manual experience. This creates several operational challenges:

1. Low Water and Fertilizer Utilization

Traditional irrigation and fertilization can cause uneven distribution of water and nutrients. Excess input may be wasted through runoff, evaporation, or ineffective root-zone delivery.

2. High Labor Demand

Manual irrigation, fertilizer application, valve switching, and field inspections require significant labor, especially across larger planting areas.

3. Disease Risk from Improper Humidity Control

In vegetable production areas, excessive surface moisture and poorly managed irrigation may increase the risk of soil-borne and humidity-related crop diseases.

4. Limited Precision in Crop Nutrition

Different crops and growth stages require different irrigation and nutrient strategies. Without a digital control system, it is difficult to adjust water and fertilizer delivery accurately.

Smart Fertigation and Irrigation System Architecture

An Integrated Water and Fertilizer Management System

The project adopted a complete smart irrigation architecture consisting of:

Water Source System
Filtration System
Intelligent Fertigation System
Field Pipeline Network
Drip Irrigation and Irrigation Belts
LoRa Wireless Smart Irrigation Control

This structure formed a closed-loop irrigation and nutrient delivery system from the equipment room to the crop root zone.

1. Water Source and Filtration System

Ensuring Stable Irrigation Water Quality

The irrigation headworks included water storage, filtration, and pressure-stabilizing components to ensure that water entering the field network was suitable for precision irrigation.

Key Functions

Removes suspended impurities
Protects irrigation pipelines and emitters
Reduces blockage risk
Improves long-term system stability

Reliable filtration is especially important for drip irrigation systems, where clogging can affect uniform water and fertilizer delivery.

2. Smart Fertigation Unit

Delivering Water and Nutrients Together

The fertigation unit automatically mixes fertilizers with irrigation water according to preset crop requirements. This helps provide a more consistent nutrient supply than manual fertilizer application.

Key Advantages

Uniform fertilizer distribution
Improved nutrient absorption
Reduced fertilizer waste
Better support for crop growth stages
More stable fertigation concentration

By delivering nutrients directly through irrigation water, crops can receive a more balanced supply at the root zone.

3. Field Irrigation Network

Efficient Distribution Across the Demonstration Area

The field engineering section included:

Main irrigation pipelines
Branch pipelines
Drip irrigation belts
Field valve control nodes
Wireless irrigation management units

This setup made it possible to manage irrigation by planting zone and crop type, supporting different water needs for vegetables and rice.

4. LoRa Wireless Smart Irrigation

Remote Control for More Flexible Farm Management

The project integrated LoRa-based wireless irrigation control, enabling operators to remotely manage irrigation in different field sections.

System Capabilities

Remote valve opening and closing
Zone-based irrigation scheduling
Reduced manual field operations
Faster response to crop water demand
Easier expansion for larger farms

This approach helps reduce the need for workers to manually inspect and operate valves across the entire site.

Before and After Smart Irrigation Upgrade

Project	Before Upgrade	After Smart Fertigation and Irrigation
Irrigation method	Manual or experience-based irrigation	Scheduled and zone-based irrigation control
Fertilizer application	Manual fertilization	Automated fertilizer dosing
Field operation	Workers manually switch valves	LoRa wireless remote valve control
Water distribution	Uneven water delivery	More uniform drip irrigation distribution
Crop management	Limited data support	Data-driven farm management
Labor demand	Frequent field inspection	Reduced manual field operation
Expansion ability	Difficult to scale	Easier expansion for larger farms

Expected Project Benefits

The smart fertigation and irrigation project is designed to help vegetable and rice farms improve field management efficiency through more accurate water and fertilizer delivery.

Key expected benefits include:

Improved irrigation uniformity across different planting zones
Better fertilizer application consistency through automated dosing
Reduced manual valve operation and field inspection workload
Lower risk of over-irrigation in vegetable production areas
More flexible irrigation scheduling for different crop types
Better support for scalable digital agriculture demonstration projects
Improved long-term operation stability through filtration and pipeline protection
