Cropping and Soil Fertility Studies at Keravat, New Britain.

Abstract

At the Lowlands Agricultural Experiment Station, Keravat, on the Island of New Britain, two long term farming systems trials have been in progress since 1954. The trial sites are 4 degrees south of the equator, near sea level, and the climate is wet tropical. The trials are sited on deep pumice derived alluvial soils which, in the virgin state, supported rain forest.
