This paper describes on-going research in Georgia to use soil EC data from a Veris 3100 system to predict nematode hotspots in 5 south Georgia cotton fields. Soil EC can be used to indentify soil texture. Root-knot nematodes tend to favor lighter, more sandy soils. We will present results from a 2005 study involving soil EC mapping, soil texture mapping, and nematode mapping. We expect our results to indicate the ability to predict likely nematode hotspots from soil EC data. This will allow a grower to target nematode sampling and nematicide application.
