RE: Corn and an ATV.
Rob - When planting with an ATV (broadcasting) - You just need to plant an extra 30-40% of seed than you would with a planter - thats because - a good 1/3 of the seed will not get deep enough.Its OK - Corn is cheap enough, and you don't have an alternative - I like 2" deep like Ron M Says.
I very often go back over our corn plots and cultipack - because the soil we plant in sometimes never really dries out at planting time - and the seed doesn't always get covered like it should.
Make sure you use RR corn - and add plenty of Nitrogen - Ph isn't as big as a factor as it is with legumes.
