Rob, corn needs to be planted about an inch or 2 in deep according to the weather at the time , is the ground cold, etc.you could work up the ground with the ATV disc and then plant the corn with a small planet Jr that you push along by hand that many people use for planting their gardens, you just need to be sure that you get corn plates, along with the veggie planting plates. The planter should give you enough compaction when you plant to satisfy that need. When you plant be sure and use Roundup ready corn so you can spray it for weed control simce you wont be able to cultivate it...Last year the farmers I help out planted over 4,000 acres of corn and we have 2- 16 row planters, but the process is still the same no matter how much you plant....get the lime and nutrients right first...
