Abstract: Disclosed herein are various devices, systems, and methods for protecting open seed trenches form ingress of foreign material, such as plant residue. The preventing foreign material from entering the open seed trench during planting increases crop yield by minimizing delayed germination and late plant emergence. Various implementations of adjustable row cleaners may be used to prevent ingress of foreign material. Also, various shields may be disposed on the row units of a planter to prevent ingress of foreign material.

Abstract: The disclosed apparatus, systems and methods relate to devices, systems and methods for on-the-go monitoring and controlled feedback in a supplemental downforce application. Certain implementations provide real-time monitoring of furrow depth via contact and non-contact approaches, some of which are combined with gauge wheel feedback to calibrate and otherwise control the application of supplemental downforce to the row unit. A combination of sensor types are employed in collecting furrow depth measurements, which can be used to adjust the supplemental downforce through a control system module. A gauge wheel load sensor may be used to modify the application of supplemental downforce.

Abstract: The disclosed apparatus, systems and methods relate to determining cross track error between a stored planted location and the actual physical location of plants. An array of active light sensors is mounted on a vehicle for travel above the plants. The array of active light sensors generate an electrical signal from each sensor corresponding to the reflected light from the sensor. A computer system generates a reflectance curve from the array of sensors to determine the location of a plant below the array of sensors and also generates the cross track error.

Abstract: A method of quantifying growing plants in an area is disclosed wherein the area is scanned with an active light sensor which provides a data signal when a plant is present that is distinct from the data signal provided when a plant is not present. The data signal is analyzed to determine at least plant population densities, the spacing of plants, the number of emerged plants versus planted seeds, the size of the area that has unproductive plants or an estimate economic and/or yield loss. Overlapping sample areas can be used to improve the accurate quantification of plants.
