Maintaining Alabama’s expansive road network demands a skilled team. Agronomists are essential in managing roadside vegetation. Leading this effort is Jacob Hodnett, the state’s senior agronomist with the Alabama Department of Transportation. Overseeing operations, Steven Drake directs the West Central Region, while Billy Aaron heads the Southeast for ALDOT.

Balancing Beauty and Safety

A typical day for an ALDOT agronomist involves a variety of tasks, from answering questions about vegetation management to providing training and support to state crews. The goal is to equip these teams with the knowledge and tools necessary to maintain our roadsides efficiently and effectively.

ALDOT has established guidelines for mowing and herbicide use. The reality of managing such a large area requires flexibility. Safety is always the top priority, followed by cost-effectiveness. Each roadway presents unique challenges, requiring tailored solutions.

Beyond Mowing

Roadside management goes beyond simply keeping the grass cut. ALDOT recognizes the importance of pollinators and wildlife and is experimenting with different management practices to create habitats beneficial to all wildlife. Three specific locations are currently being studied as part of this initiative.

Vegetation management is the process of promoting stable, low-growing plants and stopping weeds or unwanted growth. ALDOT agronomists save money by eliminating mowing cycles and improving site-distance for motorists.

A Passion for the Land

The agronomist’s role demands a deep understanding of Alabama’s diverse ecosystems. ALDOT agronomists, armed with strong educational backgrounds in agronomy and soils and seasoned by diverse agricultural experience, tackle roadside management challenges.

“We utilize many different types of tools; I would say our greatest tool that we have at our disposal is the individuals in the districts that get the job done. Their experience and know-how is key in what we do. With out them it would be a jungle out on the roadsides,” said Hodnett, senior agronomist.

By providing comprehensive training and support, ALDOT empowers its team to maintain safe and environmentally friendly roadways for all Alabamians.
