Proper use of treated industrial wastes contributes to the circular economy and reduces wastes that would have been disposed of in landfills or by incineration. This publication clarifies Georgia’s legal definition of “soil amendments” and highlights current policies governing the application of processed wastes on farm lands in Georgia. Compliance with these regulations maintains a quality environment in Georgia and ensures the long-term sustainability of manufacturing and food processing industries.

The growth and development of sweet corn is affected by accumulated heat units, measured in growing degree days (GDDs). This publication provides South Georgia sweet corn growers with insights into the relationship between temperature and GDD units and the key growth stages of sweet corn. This will help growers make informed decisions about the timing for planting, management practices, irrigation, and harvesting.

In Georgia, there are many small-scale producers that largely use ecological production practices, such as Certified Organic, and sell in farmers markets or other direct marketing channels. As these direct markets begin to saturate, these producers may need to forge a path beyond direct markets to wholesale or institutional markets that want sustainable products. Food hubs may offer a path for these small farms to scale up. There are three overlapping forms of food hubs in Georgia. Each has different markets and thus different requirements for the producers who sell to them. This publication discusses the types of food hubs in Georgia and gives producers guidelines on which form of food hub may work best for them.

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a group of more than 9,000 manmade chemicals that have been in use worldwide since 1940, primarily in industry and numerous commercial and consumer products. The widespread use of PFAS for the past several decades has raised concerns due to their persistence, bioaccumulative nature, and potential adverse health effects. This publication provides information about the background, uses, and environmental and human health consequences of PFAS chemicals, as well as the EPA’s primary drinking water regulation standards and water treatment systems for removal/reduction of these chemicals from drinking water. Testing options and PFAS monitoring efforts by the Georgia EPD are included along with references for further reading.
