A sustainable and ecologically sound turf system succeeds when it is built on a foundation of sound agronomic practices matched to site characteristics and turf performance objectives. We will consider how factors such as aspect, light, soil condition and health, proximity to environmentally sensitive areas, and degree of turf maturity can inform decisions regarding implementation and timing of key cultural practices. In particular, we will examine the selection and establishment of appropriate turfgrass species and cultivars as an essential component of turf sustainability.
