A system for removing seeds includes a track, one or more carts moveably disposed on the track, one or more sensors, a removing device, and a controller. The controller includes one or more processors, one or more memory modules, and machine readable instructions stored in the one or more memory modules that, when executed by the one or more processors, cause the controller to determine a location of one or more of one or more contaminated seeds and one or more contaminated plants on the one or more carts based on information received from the one or more sensors and instruct the removing device to remove one or more of the one or more contaminated seeds and the one or more contaminated plants based on the location.

Systems and methods for autonomous crop maintenance and seedline tracking in agricultural environments. The methods involve determining crop density within a field, generating kernel density estimations, and identifying seedline locations by analyzing local minima in crop density and their persistence. Virtual bands are generated around the seedlines to focus maintenance efforts, such as weeding or thinning, on these areas while ignoring out-of-band regions.

Apparatus for control of vegetation having at least a part within a body of water such as a lake which includes a generally planar surface and a plurality of Ultra Violet Light-C (UV-C) light sources capable of producing UV-C light at substantially a wave length of 254 nm, the sources being disposed on the generally planar surface. The method for control of vegetation includes providing a generally planar surface, providing the plurality of UV-C light sources capable of producing UV-C light at substantially a wave length of 254 nm and positioning the sources on the generally planar surface, and positioning the generally planar member with the UV-C light sources within 12 inches of vegetation to be controlled, and exposing the vegetation to be controlled to the UV-C light sources for a finite period of time.

Apparatus, systems and methods are provided for crop stand optimization. In some embodiments a field is planted at a first population prescription determined based on a first data set including forecasted weather. A subsequently determined second population prescription is determined based on a second data set determined after planting, and the planted crop is thinned according to the second population prescription. In some embodiments the crop is selectively thinned to remove plants having a plant removal index below a threshold.
