How many acres?
I just spent $1300 for seed, 1000# pelletized lime (for just one acre) herbicides/ surfactant, but that will cover 23 acres. Plan on spending about $750 in fertilizer in a buggy IF I get a good stand and rains are somewhat consistent. so thats around $50 per acre in seed and chemicals, not counting fertilizer and diesel in tractors.
50lbs awnless wheat/ 3lbs crimson/ 3lbs Balansa/ 3lbs ecotill radishes/ 3lbs purple top turnips per acre. Plus I found a bag of old buckwheat in the back of the shed I'm going to add 2lbs per acre. Dunno if that will even germinate, as it's over 3y old.
