Do you fertilize through the pivot system?
No fert through the pivot. Corn and cotton are fertilized by knifing liquid nitrogen (and sometimes amendments like zinc), into the beds right along side of the plants — this is done with a rig that attaches to a tractor. Corn is also fertilized at first with a starter solution that is put in the seed furrow by the planter. We also occasionally fly pelleted fert on corn with an airplane. There have been times when we applied foliar feed to the cotton with a spray rig.
