UGA evaluates short-day onion varieties to determine their performance characteristics in standardized growing practices. Variety entries for the trial are submitted by participating seed companies. These trials are conducted at the Vidalia Onion and Vegetable Research Center located in Lyons, GA. There were 53 varieties entered into the 2023–2024 UGA onion variety trial.

This study looked at the relative availability of sulfur from various soil profile depths by growing onions on raised beds with differing depths to the claypan and varying sulfur content.

This study examined the extent of variability in soil properties across the Vidalia production region and how those differences are related to onion yield and pungency. While soil characteristics, like claypan depth, clearly play a major role in onion productivity and flavor profile, soil series classification alone is not sufficient to describe how soil characteristics influence onion yield and pungency. Further research is needed.

This publication covers microfiltration, which is used for physical removal of contaminants from water. It describes how these processes work, their situation-specific usefulness/applications, maintenance needed for their proper functioning, and guidance for the consumers to select the appropriate filter.

Lime mud is a by-product produced in pulp mills as part of the process that turns wood chips into pulp for paper. The pulp mill cooks wood chips with sodium hydroxide to extract the wood fiber used to make paper from the lignin that binds the wood together. During this process, sodium hydroxide is converted to sodium carbonate. The pulp mill than adds calcium oxide, also known as quicklime, to convert the sodium carbonate back to sodium hydroxide in order to use it again. In the process, calcium carbonate is formed.

This bulletin provides the general public a quick reference for some commonly used standards for metal concentrations in biosolids and various by-products intended for land application. Most of the standards presented here are regulatory; however, we have also included information on average metal concentrations in agricultural soils.
