Irrigation on Demand (IOD)
Introduction

Irrigation on Demand (IOD), also known as variable rate irrigation, is an innovative agricultural technique that optimizes water usage for crop cultivation. It operates by monitoring the water potential in the soil and roots, and activating irrigation when plants indicate a need for water. This approach is tailored to the unique water absorption characteristics of different plant species, ensuring optimal growth and reducing water stress.

Technique Overview

1. Water Potential Monitoring: IOD relies on measuring the water potential of the soil and roots. This metric reflects how hard a plant has to work to extract water from the soil. Different plants have varying thresholds for water stress. For instance, Palm dates, adapted to desert conditions, start experiencing stress at -50 centibars (cb), while avocado trees may begin stressing at -20 cb.

2. Stress Reduction and Growth Optimization**: By irrigating based on root status, IOD minimizes stress risks and enhances plant growth. The system adjusts to different stages of a plant's lifecycle, adapting to changing water consumption rates throughout the seasons.

3. Dosage Determination: Various methods exist for determining the appropriate amount of water. A novel approach involves irrigating by depth, where a water potential sensor is placed below the root zone. Irrigation ceases when water reaches this depth, ensuring precision and encouraging root growth to the appropriate depth.

4. Environmental Impact: IOD not only saves water but also reduces the likelihood of fertilizer leaching into groundwater, mitigating environmental pollution.

5. Frequency vs. Fixed Dosage: Another technique involves maintaining a fixed water dosage while varying the frequency of irrigation. This method adjusts to the plant's evolving water needs while controlling the total water usage.

Benefits and Results

- Water Savings: Studies have shown that IOD can lead to 30-50% water savings.

- Yield Increase: Implementing IOD can result in up to a 30% increase in yield compared to the traditional Evapotranspiration (ETo) protocol.

- Root Growth: Encourages deeper root growth, leading to stronger and more resilient plants.

- Reduced Environmental Impact: Decreases the risk of groundwater contamination from fertilizers.

Industry Impact

Companies like Viridix are pioneers in the field of IOD. They have developed technologies that enable precise and efficient irrigation, aligning with the needs of various crops. Viridix's innovations have contributed significantly to the advancement and adoption of IOD in modern agriculture, demonstrating the effectiveness of this approach in real-world scenarios.

Conclusion

IOD represents a significant step forward in sustainable agriculture, offering a method that aligns with the natural needs of plants, conserves resources, and boosts productivity. Its adoption is a testament to the agricultural sector's ongoing commitment to innovation and environmental stewardship. Moryegereman (talk) 15:57, 19 December 2023 (UTC)
