Precision irrigation framework with marginal productivity mapping
A precision irrigation framework using constrained seasonal groundwater budgets and remote sensing to optimize water productivity. It focuses irrigation on high-yield potential areas, enhancing efficiency and sustainability in agriculture.
Overview
The proposed precision irrigation framework integrates constrained seasonal groundwater budgets with remote sensing and land data assimilation to optimize water use in agriculture. By implementing a marginal productivity index (MPI), the system prioritizes irrigation in zones with the highest yield potential, aiming to sustain aquifer resources while maximizing water productivity. This innovative approach not only enhances yield efficiency but also aligns with groundwater conservation strategies, offering a practical solution for farmers to improve profitability and comply with stabilization targets.
Technical specifications
Key features:
- Utilizes remote sensing data, specifically daily evapotranspiration from OpenET, to inform precise irrigation timing.
- Develops marginal productivity zones by analyzing soils, topography, and crop history.
- Prioritizes water allocation to high-MPI zones, ensuring efficient use of limited water resources.
- Conducts field trials with linear-move irrigation systems and monitors crop water stress using drone imagery and soil moisture sensors.
Applications:
- Applicable across the western Corn Belt and other regions with similar climatic and resource conditions.
- Provides a scalable framework adaptable to various agricultural settings.
Technology readiness level
The precision irrigation framework is currently at a Technology Readiness Level (TRL) 4, indicating that it has been validated in a laboratory environment and is undergoing field trials in Garden City, KS. Further validation is planned to demonstrate its effectiveness and scalability.
