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 disclosure relates to agricultural systems. The systems have stalk sensor assemblies and/or data visualization systems. The stalk sensor assemblies are configured for assessing the size and other characteristics about crops, such as corn and other grains entering an agricultural implement, such as a harvester. The stalk sensor assemblies may use an estimation of the stalk perimeter to establish stalk size and therefore further features about the crop. The visualization system utilizes data from the stalk sensor assemblies to calculate and display relevant information about the crop.

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: The disclosed apparatus, systems and methods relate to devices, systems and methods for reducing cross-track error in harvesting row crops such as corn. A cross track error system including a corn head, a row unit disposed on the corn head. The row unit including a set of stripper plates, a resilient member disposed proximal to the stripper plates, a sensor unit in communication with the resilient member, and a processor. The processor is constructed and arranged to process signals generated by the sensor unit in response to deflection of the resilient member.
