The quantities are based on the Stomata Greenkeepers' many years of experience. Organic, preferably plant-based fertilizers are preferred; fertilization must not trigger any surge growth.
Poa annua promotes long-term exceedance of the recommended values. With N fertilizer applications of around 30 g/m² and frequent scarification, a pure Poa population will develop in a few years.
