I am currently looking to purchase a Bourgault paralink drill. So many options regarding fertilizer placement. I am currently looking to put approx 250 lbs of n next to seed. Is this too close for side banding? Am I better off with midrow banders. I am leaning towards side banding as less moving parts. Also regarding midrow banders, are the discs better than the knife set up. I dont see many midrow knives so wondering if that isnt such a good choice? Thanks in advance!
