I need some help with this one. On sort of a spur of the moment deal I planted some corn on ground that I hadn't put any zinc out with the dry mixed fertilizer. I also didn't have any N out yet and I am going to put some 28% out with a knifing rig. The dealer that I am getting the fertilizer and knifing rig from has this liquid zinc product from Agro.Culture Liquid Fertilizers. The name on the label reads Zinc 4% Zonc. The product shows to be 9.61 lbs per gallon. My soil samples call for 10 lbs zinc to the ac.  How much of this product does it take to get a actual 10 lbs of zinc to the ac.
