An agricultural system includes a controller comprising a memory and a processor, wherein the controller is configured to receive data from a first and second sensor, each of which are mounted on an agricultural header and configured to output data indicative of one-dimensional (1D) distances. The controller is configured to determine a first horizontal distance from the first sensor to a first plant stalk and a second horizontal distance from the second sensor to a second plant stalk based on the 1D distance data. The controller is also configured to control a steering system of the agricultural system to adjust a position of the agricultural header relative to the first and second plant stalks based on a difference between the first horizontal distance and the second horizontal distance.
