Which area would generally have the highest nitrogen application requirements?

Putting greens require the highest nitrogen application because they are specifically maintained to achieve a very dense, smooth, and fast playing surface. The nature of a putting green demands that the turfgrass be kept in peak condition to ensure optimal performance for golfers. This usually involves higher inputs of nitrogen to promote fast growth, lushness, and the ability to recover quickly from wear and tear due to foot traffic and mowing practices.

On putting greens, the grass is often kept shorter than in other areas, which requires more frequent mowing and, consequently, a need for more nutrients to maintain health and vigor. High nitrogen levels facilitate aggressive growth and improve root development, enabling the grass to withstand heat and drought stress.

In contrast, naturalized areas, golf course turf, and fairways have less stringent requirements for nitrogen application. These areas may be managed with a focus on sustainability, aesthetic appearance, and playability rather than the specific performance targets needed for putting greens. Therefore, putting greens stand out as an area with the highest nitrogen needs within a golf course setting.
