Lime can release soluble nitrates from your fertilizer.. But if ph. is low the turf cant use it efficiently anyway.. Bring your ph#. up with a pulverized lime, and then a pelletized lime for a slow release effect. AS you know the recommended rate is all the soil can handle at one time but pulverized lime will leach fast and the pellet will slow release. Also try a soil conditioner like Gypsum this will help hold your ph.
