There are recommendations: 2.07 lb N, 0.92 lb P2O5, 1.61 lb K2O. The test uses Mehlich 1 and I can't interpret the numbers because I don't have Mehlich 1 recommendations. However their recommendations sound reasonable. You would look for a fertilizer with roughly the same amount of nitrogen and potassium and half the amount of phosphorus and do two applications. Aim for 1 lb/k of nitrogen each application. Maybe one now and one in early fall. Or do them both in the fall. What fertilizers are available (which NPK numbers)? He might also consider doing a late fall application of only/mostly fast release nitrogen after the grass has stopped growing but before the ground freezes. He should not use lime. His pH is spot on.
