Weed mapping
During the first few weeks of the growing season, make a detailed weed map for each field. This map will provide information on the location of problem weed infestations and help monitor changes in these infestations from year to year. Include notes on perennial weed locations, severe infestations of annual weeds, and differences in weed populations in various areas of the field. Weeds located in fence rows, near the edges of the field, and along waterways also should be noted.
When drawing the weed map, outline the boundaries of the field and indicate points of reference. Mark any distinguishing features such as waterways or buildings. Locate the problem weed areas in the field and draw them on the map, using the names of the weeds along with their estimated density.
