Remote Sensing for Identification of Weeds in No-till Corn

Weeds infesting crop fields are rarely uniformly distributed, especially under minimum-tillage practices. Therefore, the total amount of herbicide chemicals used can be greatly reduced by first identifying the location and type of weed patches in the fields, and then applying the correct type and concentration of chemical to those areas. This research is aimed at developing a remote sensing technique for identifying and mapping weed patches.
