Hey, I am bidding on my first big job for athletic fields and i am having a hard time pricing all the fertilizers. if someone can help me with this so i can put in a bid it would be very helpful. They want spring fert w/pre-emergent and 60% s.c.u., fall fert and reseed, and winter fert. Thank you for any input cost per acre on these is what i am looking for. all the prices i found are super high.
