Target Audience:Farmers, consultants and extension personnel. Changes/Problems:No data was collected in 2017 due to the wet growing season. What opportunities for training and professional development has the project provided?Attended and participated in several Ohio State Extension fields presenting about the use of imagery and sensors within inseason cropping decisions. How have the results been disseminated to communities of interest?Through Ohio State workshops and fields days along with the Ohio State eFields report (https://digitalag.osu.edu/efields). What do you plan to do during the next reporting period to accomplish the goals?

What was accomplished under these goals?
Between 2017 and 2019, scheduling pivotirrigation projects were planned with data only collected in 2018 and 2019. For 2018 and 2019, wireless soil moisture sensors were used to schedule pivot irrigation for corn and soybean production resulting in not only a yield increase between irrigated and non-irrigated crops but also more timely scheduling of irrigation events. On average, irrigation was scheduled two days earlier than farmer based decisions on managing pivots. As a result for using the wireless soil moisture sensors, soil moisture was maintained within optimum levels in 2018 using irrigation to apply water in between rain events thereby not allowing soil moisture to be a limiting yield factor for corn or soybeans. In 2019, the months of July and August were dry with no rainfall. The soil moisture sensors prompted the farmer to irrigate earlier than normally scheduled while also adjusting the amount applied (0.75" to 1.0") during ciritical reproductive growth stages. As a result, the soil profile between 0.5 and 1.0 m was maintained at the optimum moisture content though deficient irrigation during these two months. As a results of having the wireless soil moisture sensors, the corn yield potential was maintained.

Target Audience:This project has intended to reach farmers, agronomy consultants and other supporting farmers with their irrigation management. Changes/Problems:
Nothing Reported
What opportunities for training and professional development has the project provided?A webinar was held to overview wireless soil maoisture sensors for Ohio State Extension educators and farmer collaborators. How have the results been disseminated to communities of interest?There is nothing to report as 2017 represented Year 1 of this new project. What do you plan to do during the next reporting period to accomplish the goals?

Impacts
What was accomplished under these goals?
Wireless soil moistures sensors were acquired and used this year for two irrigation systems in central Ohio. Data that included soil moisture and temperature was collected and evaulated for use in scheduling irrigation events in 2017. Data along with soil information were used to develop and evaulate irrigation scheduling for the growing conditions of the Miami Valley understanding how this information coupled with the technology could improve water use efficiency for corn and soybean production within river bottom soils. The focus of developing the irrigation scheduling protocal has been to reduce applied water to corn and soybeans within this region to preserve water quanity within the Miami Valley Acquifer.

Target Audience:Farmers, agronomists, and consultants Changes/Problems:Wet spring and early growing season caused replant for several intended study sites. What opportunities for training and professional development has the project provided?Attended and participated in several Ohio State Extension fields presenting about the use of imagery and sensors within in-season cropping decisions. How have the results been disseminated to communities of interest?Workshops and fields days. What do you plan to do during the next reporting period to accomplish the goals?

What was accomplished under these goals?
2017 represented a wet spring for Ohio with replant at several crop production studies. No data was collected related to irrigation other than final yield data that did not present data used to analyze treatments.

What opportunities for training and professional development has the project provided?Professional developmentincluded participating in2 Ohiofield days and 1 regional project during the summer discussing the the linkage of water and nutrient management (e.g. N for corn) to maximize profit. Participants learned about the benefits of in-season measurements to helprefine water and nutrient decisions and how remote sensed imagery could be valuable to supply information for in-season N applications. How have the results been disseminated to communities of interest?Results have been disseminated to farmers and agronomists through traditional field days. What do you plan to do during the next reporting period to accomplish the goals?2017 project is planned to support this effort and provide additional year of data.
Impacts
What was accomplished under these goals?
The prime impact of this effort has been the identification of using remote sensed imagery to evaulate in-season crop health but more importantly the influence of supplied water to crop vigor and yield. We have been able to explore how this imagery can track crop development and vigor supplying information to make in-season fertigation decisions.
