I'm nae much of a gerdener manny masel JJ but with my limited amount of knowledge around growing gress and keeping it green then i believe it needs fertilizer and i don't think there is many a better fertilizer than pure sh1te and god alone knows there has been plenty of pure sh1te in abundance this season gracing the pittodrie turf week in week out, so I guess that's going someway to keeping the grass and playing surface in as good nick as it currently is.
That and a decent groundsman and staff so it's a win win situation all round
As for the greenkeeper in golf I normally prefer a fast green masel but fk the greens over here anoo are like putting on snooker tables with a coating of black ice on top of them
