I saw some new fertilizer this summer. It was called 27,0,0,12. I had never heard of it but the turf farms were buying it up. What it amounts to is perlated ammonium nitrate. The reason it is not 34,0,0 is that it is covered in lime. By perlating it in lime, any trucker is able to haul it without the hazardous endorsements thus reducing the cost of the fertilizer. Also, lime coating it prevents it from melting in our humidity. We also discussed the possible reduction in the need to lime since you would be liming when you put this out. Maybe not that much, but it would still reduce the amount of lime you would need with time. So with that in mind, I don't think lime and nitrogen are going to counter each other outside of a liquid solution as Dave pointed out.
