There are a lot of tip sheets out there on how golf courses/turf systems can reduce their environmental footprint. Sustainable Turf Care by the NSAIS provides a few good points, in particular the compost section, here's the intro:

In contrast, mature compost enhances populations of soil organisms by providing them with an excellent source of nutrients.
