EC Nebraska | It depends on your soil tests and the rate of zinc sulfate, but yes, it can be a good method.
I've got soil tests >1% and I'll add in 10-15 lbs of zinc sulfate with the MAP. I'll probably repeat the application in two years. If I wanted to "fix" the zinc for several years to come I might go 20-25 lbs of zinc sulfate at one shot, but that's not my preferred option. (as much because of pocket book as anything, but also because I'd rather spread it out).
