Abstract

A soil detection and planting apparatus. The apparatus includes a vehicle and a controller coupled to the vehicle. The apparatus further includes a planting device coupled to the vehicle, the planting device configured to plant seeds or plants into a soil material. The apparatus includes a ground penetrating radar sensor coupled to the vehicle. The ground penetrating radar soil sensor is configured to scan the soil material up to a designated depth beneath a surface of the soil material, wherein the ground penetrating radar soil sensor is further configured to provide a sensor feedback signal to the controller with respect to an intrinsic characteristic of the soil material. The controller is configured to instruct placement of a seed or a plant into the soil material based on the feedback signal.
