Field Research

• Soil samples, NO3-N, NH4-N
• Biomass samples, Mass, TKN
• Irrigation
• Fertility rates
• Harvest

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

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
