Fig. 1. Grass yield (a) and N uptake (b) for 1993 mid-season growth period (13 July–17 September). All compost treatments plotted with a common regression model because compost treatments were not significant at P = 0.05 (Tables 4 and 5). Yield and N uptake (left axis) are for same time period as yield accumulation rate and N uptake rate (right axis).
