Research Project: Ars-El Reno Iag Dataset and Review Input for Pastureland Ceap Modeling

Location: Forage and Livestock Production Unit

Project Number: 6218-21610-001-13
Project Type: Interagency Reimbursable Agreement

Start Date: Jun 01, 2013
End Date: Dec 31, 2014

Objective:
1. Develop databases suitable for testing APEX model for forage growth in mono- and mixed-cultures. 2. Test accuracy of APEX model output using weather and forage growth databases.

Approach:
1. Utilizing existing data from Grazinglands Research Laboratory projects, organize into suitable databases for access by the WinAPEX model. Data from previous experiments from agronomic and animal grazing trials will be accessed. Additional data will be sought with collaborators where long-term experiments have been conducted. 2. Make test runs with the WinAPEX model using weather records, soil and other climatic information and statistically compare model results to actual production data. Data will be organized to cover a broad range of weather patterns to determine sensitivity to important climatic variables.
