Plant Water Requirements
2:00 p.m.-2:30 p.m. | Options for Estimating Plant Water Requirements for Irrigation Scheduling in Louisiana | Stacia L. Davis Conger, PhD, LSU AgCenter | 0.5 CEU
The determination of whether to apply irrigation to agronomic crops in Louisiana was historically instinctive rather than by plant water requirement. Indicative results will be presented from soil moisture sensor studies and the ongoing ET gauge study to summarize overall progress and next steps.
2:35 p.m.-3:05 p.m. | Use Satellite Imagery to Calibrate Crop Coefficient | James Han, PhD, Lindsay Corporation | 0.5 CEU
Crop coefficients (Kc) are widely used for predicting crop evapotranspiration for irrigation management; however, the spatial and temporal variation of Kc for different crops can significantly affect ET estimation. Using satellite imagery to calibrate Kc has the potential to solve the issue due to cloud-based technologies and hi-res satellite imagery being more cost-effective.
