In researching how to fertilize various plants, ammonium nitrate is referenced regularly. During a recent visit to my local garden center, the personnel informed they will no longer sell ammonium nitrate as it has been misused. I am asking for a recommendation to replace it that would serve the same purpose. Would ammonium sulfate do it for my vegetables? Thanks!

I would not use that very high nitrogen fertilizer on any vegetable. It works ok on corn if you know what you are doing but I don't find it necessary. There is always a danger of burning the plants even with ammonium sulphate which does not have as high a nitrogen concentration as ammonium nitrate. Nitrate of soda is just16% nitrogen but will still still burn plants. Just for reference I use 10-10-10 on brassicas, corn etc and 5 -10-15 on everything else. High nitrogen ferilizers can be used as explosives. Every since Oklahoma City, ammonium nitrate which is 34% nitrogen has been controlled. It is still available, but you will probably only find it at a vendor to commercial corn growers. Most vegetables do well on NPK ratio of 1-1-1. They need all three nutrients and only grasses such as corn can use a higher ratio.
