Chemigation in Georgia
Chemigation is an inclusive term referring to the application of a chemical into or through an irrigation system. It includes the application of fertilizers, acids, chlorine and pesticides. Chemigation can save time, reduce labor requirements, and conserve energy and materials. Chemigation is beneficial, however, only to the extent that the irrigation system is adequately designed, fully functional and properly managed.

Farmers have known for centuries that animal manures spread on pastures and cropland can improve soil fertility. In the 1920s, farmers began to use sludge from municipal wastewater treatment plants as a fertilizer. Through decades of research, the scientific and agricultural communities have come to understand that municipal sludge or “biosolids” contain valuable nutrients and organic matter that improve the soil in a way similar to animal manures. It is important to understand that biosolids are not raw sewage. Biosolids are organic solids that have been treated to stabilize organic matter and reduce disease-causing organisms or pathogens.
This resource was developed to help answer some common questions regarding the use of biosolids and to give farmers benchmarks for good practices.|

Drip irrigation is an important component of vegetable production systems in Georgia. Drip irrigation is more desirable than other irrigation methods for several reasons. Two important advantages are (1) water conservation and (2) potentially significantly improving fertilizer management. Fertigation is the timely application of small amounts of fertilizer through drip tubes directly to the root zone. Compared to conventional ground application, fertigation improves fertilizer efficiency.
