The primary productivity of lawns in a temperate environment.
Abstract
Of 2 lawns studied one was not fertilized or irrigated and was infrequently cut and the other was fertilized, irrigated and cut weekly. The dominant grass in both lawns was Festuca arundinacea. The closely managed lawn had a lower species richness than the less managed lawn. The annual net primary productivity (as assessed from clippings, stubble and roots) was very similar for both lawns, 1650 g/m2 (6400 Kcal/m2) and equivalent to that of other managed grasses such as maize and wheat.
