Depends on what the hay crop is. I normally fertilize grass and grass clover hay in March. Occassionally, if hay is REAL short I will fertilize grass hay with ammonium nitrate in August. Hard to justify with high fertilizer prices and good supplies of spring hay.

Alfalfa, I like to fertilize after second cutting with P and K and again after last cutting with K.

Normally, I use P and K to soil test. Grass hay will get 250# ammonium nitrate per acre. Alfalfa after the first cutting (or in the case of some today, after the second) 100# DAP and 200# of muriate of potash. I made the conscious decision not to buy N this year. At $350 a ton for ammonium nitrate, there is no way I can justify it. Cut my grass hay yields by a third. On a sample field that dropped my hay yield from 60 rolls to 40. 20 rolls at $25.00 would have just about paid what I bought in N. Not my idea of buying a job.
