Educational approach:


In general our team delivers technical assistance in a variety of ways including, but not limited to: 1) assisting producers with collecting the prerequisite data to develop a "Pipe Planner" plan, 2) utilizing the data to develop a "Pipe Planner" plan for individual fields, 3) installing soil moisture sensors on demonstration farms to schedule irrigation initiation and termination, and 4) providing technical assistance to other farmers on irrigation scheduling decisions.

Education & Outreach Initiatives

Improve water use efficiency

Reduce irrigation water usage through the adoption of improved management practices


Over the course of this project, our group utilized on-farm demonstrations, consultations, newsletters, and technical assistance to help producers in the Yazoo-Mississippi River Delta to improve water use efficiency though the use of flow meters, proper use of surge valves, computerized hole-selection for furrow irrigation, and utilizing soil-moisture sensors to initiate and terminate irrigation.

Outcomes and impacts:

Project Outcomes

Project outcomes:

As of December 2018, our team has provided well over 325 irrigation consultations in the Delta Extension Region.  These consultations include assisting with Pipe Planner, conducting flow meter checks, and providing technical assistance on soil moisture probes as well as irrigation initiation and termination decisions.  These consultations have directly impacted over 25,000 acres with agents indicating that producers are largely adopting the practices as quickly as feasible.  Agents further indicate that the knowledge disseminated through this effort could easily have a ten-fold impact in just a few years.

1,100 Farmers reached through participant's programs
Additional Outcomes:

Below is a narrative from one of our agents that is representative of the educational outcomes associated with this project.

"I have been working with this grower for a number of years in planting cotton variety trials.  This past year I was discussing with him about installing soil moisture sensors.   We decided to install two locations, one on the south and the other on the north side of the fields.  The south side being a sandy type soil with the north being a mixed soil type.  I let him keep the portable meter that I have so he could check the sensors at his convenience.  I went back the next week and he showed me a graph that he had started comparing the sandy type soil with the mixed type soil readings.  He could not believe the results, I think we will have a new producer purchasing soil sensors for his operation this year.  I will be working with other producers this year installing sensors on their operation hopefully having the same positive results that I had with this producer."

Another of our agents reported that because of the soil moisture demonstrations he has been doing, his farmers have saved multiple irrigation events on several thousand acres.  This has resulted in savings of thousands of dollars in expenses and several hundred millions gallons of water.



The funds provided by this project allowed us to equip Extension Agents with educational demonstration equipment that due to state budgets would not have been otherwise possible.  This equipment has allowed us to conduct multiple demonstrations all over the Mississippi and Yazoo River Delta.  As a result of these demonstrations, more producers are using moisture sensors to initiate and terminate irrigation events.  Also, because of the immediate and very tangible results from the soil moisture meter demonstrations, several agents have used some of their limited discretionary funds from other sources to purchase additional moisture to increase the number of demonstrations.  Finally, the items purchased with these grant funds will continue to be used after this project ends, extending the results of this specific effort far into the future.
