End Date: Jun 30, 2019
This overall project consists of four components: 1. Application of existing osmotic water potential control systems for characterizing soil water availability; 2. Evaluation of hydrothermal germination and emergence response of diverse wheat, corn and sunflower seedlots as a function of soil texture, soil water potential, soil temperature and seeding depth; 3. Comparison of existing hydrothermal models with our hydrothermal model; 4. Improvement of existing ARS crop models for predicting cumulative germination and emergence in the field.
