I've just received my soil test from you. You are recommending a high dose of N, 3-4 #/1000 sq ft. Is that a per-year recommendation, or an all-at-once recommendation?
Kent County Michigan soil and fertility issues
The recommendation is per year. If you want to fertilize less often apply half in spring and then the other half in a fall fertilizer application. You can purchase the fertilizer and then use the fertilizer tool on the MSU soil test site to calculate how much will need to be applied to satisfy your soil test recommendations. Hope that helps!
