Diagrammatic aid to turfgrass management1

  1. F.J. Wray

Abstract

Different grass species have individual responses to water and fertilizer requirement, mowing height, shade tolerance, wear, and other factors. It is often difficult to determine the suitability of grasses for given management, climatic, or survival situations. It is also difficult to determine whether two or more grasses are compatible in any given situation, and the effect that management practices will have on their respective survivals.

The triangular diagram enables the turfgrass manager, research worker, or breeder to visualize the degree of compatibility of different species under selected circumstances, and infer consequences arising from changes of management practices or new situations.

The three most useful characteristics of grasses are their individual water requirements, fertilizer requirements, and mowing heights. Numerical values are assigned to each of these characteristics and the results plotted on a triangular diagram. Grasses with similar requirements are automatically placed near each other on the diagram.

Other important characteristics, such as shade tolerance and wear resistance, can be used for situations where those characteristics are important.

The numerical values presented here are chosen to suit cool, wet conditions, but can be changed to suit other regions or specific circumstances. A good turfgrass manager will be able to substitute values based on his own experience. Additional index words: Triangular diagram, Turfgrass requirements, Turfgrass competition, Ecological interactions, Environmental adaptation.
