I planted Dekalb 54-00 last year (15-16k seeds per pound) at about 90k seeds per acre. I used the low rate feed cup and it worked decent, but I'm going to buy the kinze brush meters for this year. I'm thinking my population needs to be lowered to around 80-85k. At that rate per acre, that seed size, and planting at 5-6mph, what plate should I use?
