Planter Setup and Adjustments for Accurate Seeding of Corn and Soybean

Although tillage operations may be used to prepare a seedbed, planter operation is responsible for final correct placing of the seed for quick and uniform germination. Planter setup and adjustments can be used to at least partially compensate for the level of soil moisture, surface residue present, and general seedbed conditions at planting. Knowledge and proper planter adjustments have the potential to impact a timely start for the crop.
