| Abstract/Contents: | "Data collected in the fifth year of an investigation into the fertiliser nutrition of a Festuca rubra L. ssp. commutata Gaud. and Agrostis castellana Boiss. & Reut. sward grown on a sand rootzone are examined. The trial was sown on 8 August 1985 and fertiliser treatments began in April 1986. These consisted of three levels of each nutrient; nitrogen (100,200,400 kg ha-1 N), potassium (0,150,300 kg ha-1 K2O), and phosphorus (0,25,50 kg ha-1 P2O5) with and without lime (1427 kg ha-1 CaCO3). Results of assessments carried out in April and October 1989 are presented. These include botanical composition and cover, sand chemical analysis, surface hardness, green speed, golf ball rebound resilience and holding power. Principal components analysis (PCA) of the collective plot data showed that over 75% of the variation occurring in the data sets comprising eleven measured variables could be accounted for by four components. Superimposing the treatments received by each plot, and the measured variable vectors, onto the principal components shows the direction and relative rate of the induced variation. PCA illustrated an association between A. castellana cover, rebound resilience, hardness, bare ground cover and green speed, and a similar, but separate association between Poa annua cover, soil pH and holding power. These associations related very strongly to the effects of nitrogen and lime input respectively. Phosphorus was shown to increase the proportion of F. rubra in low nitrogen treatments, and ANOVA distinguished the more subtle effects of potassium, which increased rebound resilience. |
