Augmented Deficit Irrigation (ADI) DRAFT Concluding <br />Thoughts <br />• Historical on-farm water balance considering all supplies to determine farm was <br />water adequate. With an ADI Program limits on all farm supplies will be imposed to <br />prevent expanded use. <br />• Monitoring program for fields/farm would involve measurements of water on and off <br />(surface runoff -maybe) and monitoring for crop water use (CU/ET)---saved CU. <br />Deep percolation return flows monitored through water balance (water on minus <br />runoff minus ET). Role for water and crop consultants and ditch companies. <br />• Priority for a Corn ADI Program is farms with heavy soils where start with full soil <br />water profile and one irrigation before pollination/silking (and a 2nd irrigation late <br />during senescence to maintain returnflows); maximum saved CU and maintain yield <br />with modified agronomic practices —strive for target of 80% yield at 50% ET. <br />• Maybe "Rules and Regs" to establish fundamentals (analysis/monitoring) for entity to <br />then apply to their specific project in an IWSA / Augmentation Plan. <br />
