Stripling Irrigation Research Park striplingpark.org 3 blocks each with 27 plots – 81 total Peanut – Corn – Cotton Rotation
SmartIrrigation Corn App • Irrigation module in beta testing for android and iOS • Water balance based on rainfall, irrigation, and ET • ETc calculated using a growing degree day based Kc • Last season observations on app performance • Need a better way to estimate root growth and depth • Crop stages closely monitored • Used to develop the GDD – plant stage relationship • Plans for 2019 • Identify 2 to 3 growers in Florida and Georgia to test the app in 2019 season • Develop N module
On-Farm Demos & IST timeline Modeling In-service Trainings On-Farm Demos Years 1-5 Years 3, 4, 5 Years 4-5 1 in each state 2 in each state BMPs identified in survey
Water Schools: Timeline • Target audience: • decision makers and opinion leaders • Intended deliverables: • Extension curriculum materials • Water Schools implemented in FL and GA • Increased knowledge; Information for policy development • Timeline: • 2018: economic value of water resources – extension pubs (NIFA project by Dr. Grogan) • 2019: • Surveys and interviews of extension agents and target audiences in Florida and Georgia • SMART objectives for the program identified • Draft extension materials developed • 2020-21: • Reviews of extension materials • Trial Water Schools implemented in FL and GA
