Time to inspect your irrigation systems

By Clint Thompson

To avoid disaster due to subfreezing winter temperatures, leaky pipes and uninvited rodents, University of Georgia Cooperative Extension irrigation specialist Wes Porter recommends that Georgia growers inspect their irrigation systems before planting their crops this spring.

“We’ve got to get our irrigation systems in top shape, up and ready to run. Once the crops are up, the last thing you want is an irrigation system to break down,” Porter said.

Planting season is just weeks away for Georgia corn growers, who normally start planting at the beginning of March. Now is the best time to inspect irrigation equipment, Porter said.

“I encourage (growers) to do a quick search online or go to their county (Extension) office and ask for our spring center-pivot checklist,” he said. “It goes through the components (that growers) should check very thoroughly, has detailed pictures of the critical areas to check, discusses what to look for and even how to correct most of the problems.”

The center-pivot maintenance guide can be found online in UGA Extension Bulletin 1452, located at extension.uga.edu/publications/detail.html?number=B1452.

After farmers begin planting their crops, they may apply irrigation to establish proper plant stands or activate herbicides, and a leaky pipe or flat tire can delay those plans.

“If farmers take care of these maintenance procedures before the growing season begins, it will save them much-needed time during critical water-use periods and prevent potential yield loss to their crops due to moisture stress,” Porter said.

Growers should test irrigation systems and let them run to make sure they are operating efficiently prior to their initial use on this season’s crops, he said.

“Start the system up and make sure it’s working with proper operating pressure. It’s a good idea to check the flow rate to make sure (it’s) where it is supposed to be. You can also visually check all the nozzles to ensure they’re all working properly,” Porter said.

Growers should also make sure that sprinklers are rotating properly, in a uniform pattern.

Change the oil and clean the air filters on motors that run on diesel, gas or propane. Make sure that pumps are ready and free of overwintering animals or insects, their nests and cobwebs.

UGA Extension water educators can come to growers’ fields to take uniformity tests. Through these tests, they can check water distribution across a pivot and find where growers can potentially save money.

UGA Extension supports resilience in Georgia farm communities after Hurricane Helene 12/19/24 Emily Cabrera
Hurricane Helene wrought sweeping devastation across Georgia’s agricultural sector in late September, leaving an indelible mark on both the land and the people who tend it, bringing focus to vulnerabilities in Georgia’s farming industry and the need for more robust safety nets. In addition to the physical destruction, the hurricane took an emotional toll on Georgia’s farmers. In response, UGA Extension has prioritized mental health support.

CAES Transfer Pathways Program expands enrollment access for rural students 11/12/24 Emily Cabrera
The Transfer Pathways Program is opening new doors for rural students who dream of attending the University of Georgia College of Agricultural and Environmental Sciences (CAES). In partnership with Wiregrass Georgia Technical College and Southern Regional Technical College, students who complete required coursework at these institutions can transfer to CAES to complete bachelor’s degrees in one of three majors — agribusiness, agricultural education, and agriscience and environmental systems.

North Georgia hub fueling agricultural research at UGA 11/06/24 David Mitchell
Research in the University of Georgia’s College of Agricultural and Environmental Sciences runs the gamut — from plants, animals and dairy science, and crop and soil sciences to entomology, food science and technology, and more. It’s an expansive agenda, too broad to be housed on the university’s 760-acre main campus. For that, CAES turns to its eight off-campus research and education centers located all over the state.

UGA again ranks No. 1 in new research-based products 11/04/24 Brandon Ward
The University of Georgia once again ranks No. 1 among U.S. universities for the number of commercial products to market based on its research, according to an annual survey conducted by AUTM. For nine straight years, UGA has placed in the top two and has never appeared out of the Top 5 in the 11 years the survey has been reported by AUTM. UGA industry partners and startups released a record 66 new products developed from the university’s research in fiscal year 2023, on which the AUTM report is based.

Relief efforts continue after Hurricane Helene 10/04/24
The University of Georgia community has rallied in the wake of Hurricane Helene, coming together to address damage done to campus facilities while also lending a helping hand to friends and neighbors hit hardest by the storm. While UGA’s main campus weathered the storm with relatively minor damage, the same could not be said for the Tifton campus, where heavy rains and high winds brought down trees and power lines, leaving the campus and surrounding area without power.

UGA weathers Hurricane Helene 09/27/24
The University of Georgia’s main campus was fortunate to emerge relatively unscathed after Hurricane Helene barreled through the state early Friday morning. However, the impact was more significant at our extended campus locations. While the UGA Griffin campus reported no major damage, UGA-Tifton was hit much harder, with dozens of downed trees and power outages, as well as flooding in several buildings. Damage to farm operations across south Georgia appears to be extensive.
