A client of mine about 20 years ago in Ireland used this product below from UK based Rigby Taylor. It worked pretty well for his greens bringing them from 5 to 6 pH in about 1 year. Thatch will be an issue at pH of 5 because microorganisms cannot do their job.
Microcal pH Adjustment 25Kg
Microcal pH Adjustment is a micro-granulated form of Carbonate of Lime, making application a dust-free and simple operation. Microcal helps to re-dress the pH balance in soils that are too acidic.
RRP: £15.60

Maybe there is something similar stateside.
