Early growth responses of radiata pine to grass control and superphosphate in the Strzelecki Ranges.  D. W. Flinn.  February 1978.  5 pp. (unpubl.)

SUMMARY

A field experiment is described which evaluated the growth response of Pinus radiata to chemical grass control and superphosphate. The study was undertaken in the Strzelecki ranges on a site with a dense grass sward, moderately deep and fertile soil, and a relatively high and uniformly distributed rainfall. A strip application of Vorox M2 at 2.33 kg/planted ha soon after pine planting resulted in a 3 to 4 fold increase over control in mean tree volume after three years growth. Superphosphate application with or without chemical grass control was not associated with a growth response. Though an economic analysis was not feasible, the results indicated that chemical grass control is justified during P. radiata establishment on sites where grass competition is severe.
