Brief Project Summary:

With the experience of the severe drought during late spring and summer of 2012 and
significant yield losses for corn, soybean, and wheat in the southern U.S., many
farmers, especially in Western Kentucky, decided to install irrigation systems
following the model of many farmers in Georgia and Tennessee from years before.
The majority of irrigation systems are center pivot sprinklers. While in several
southern states, farmers, extension specialists and other personnel have some
experience with irrigation, relatively little to no work has been done on scheduling
irrigation in soybeans or even variable rate irrigation putting soybean growers at a
competitive disadvantage. In other...

Information And Results
Project Deliverables

A Beta version of an interactive ET-based smartphone irrigation scheduling tool will
be made available for limited use.
? Crop Consultants will evaluate the usefulness of the New MOIST software for
soybean producers and for improving their irrigation scheduling business, potentially
providing another means for soybean producers to increase yield and reduce
production cost via irrigation scheduling services.
• The Soybean Smartphone Irrigation Scheduling app is adopted by some farmers
in the region with irrigation capability by the end of the 2018 growing season.
• A method for deriving irrigation management zones within fields from “easily”
obtainable information, such as remote sensing of the land surface, is developed by
end of 2017.
• Soybean producers with variable rate irrigation capabilities utilize the IMZ
scheme for determining irrigation rates across a field based on soil water holding
capacity by the end of the 2018 growing season.

Final Project Results

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
