Abstract

An agricultural machine configured to harvest a crop having stalks includes a main frame and a plurality of wheels supporting the main frame from the ground. A crop header is mounted on the main frame and includes a header frame extending transversely to a forward direction and having a transverse width. The crop header is configured to cut stalks of the crop as the agricultural machine moves in the forward direction. At least one on-the-go nitrate sensor is mounted on the agricultural machine and oriented to collect electromagnetic energy reflected from or emitted by the stalks, the sensor being configured to generate a nitrate level signal representative of a nitrate level in the stalks.
