Question: I attended one of the corn college planter clinics and forgot to ask about how the weight of seed in the seed box affects my down pressure. I was also wondering how much is too much in a wet spring? I have a White 8202 planter with standard springs and the options are 50,60,105 and 115 lbs and we use it in a corn/soybean rotation with conventional tillage. I understand I should set it for the toughest part of the field that I'm in and check it like they described but I'm struggling with deciding on what that setting should be.
As you are planting, stop in the field, put your fingers down the tru vee seed trench right behind the openers. Check your seed depth. Then,pull your fingers toward you thru the side wall. If you can break the sidewall easily and the soil crushes in your hand, your down pressure is set correctly.
