I live in Minot, ND and have been having a lot of issues finding a decent fertilizer to use. I have spreaders and a 40 GALLON sprayer with a 7' foot boom. So, either liquid or granular would work for me. I also have a lot of issues with hard ground. What would be some of the remedies for this and please be descriptive on amounts used per 1,000 square foot or whatever the measuring tool is. Any help is greatly appreciated. Thank you!
