A Pilot Trial of Soil Sterilisation in a Forest Nursery

I.J. Thulin , G.M. Will and C. Bassett

A soil sterilisation trial with chloropicrin and formalin on a light textured pumice soil resulted in a significant reduction in seedling mortality and an increase in growth. Plant analyses indicate an improvement in the availability of nutrients, particularly potash. In this respect the chloropicrin was the more effective. Species used in the trial were Pinus radiata, P. nigra, Pseudotsuga taxifolia, Larix decidua and Picea sitchensis.
