Keep in mind that you cannot spray any product containing sulfer coated urea. It will plug your equipment fast. Not soluble--at least for a few weeks. Read a few hundred posts here. Also talk to several suppliers (you will get an education once you have talked to several fert salesmen). Click one or two of the suppliers listed 6 inches to the left. Buy them lunch and a few drinks if you want the real facts--and plenty of propaganda. Get a variety of opinions. You are a beginner; you need more information.
Gregson-Clark can answer you sprayer questions, talk to Rhett, he knows.
Your best bet is to use a spreader to spread fert. Then spray the weeds with a skid sprayer. Takes a little longer--but simpler and better. Done carefully--the results are better than any other method.
