Fertility studies of pasture soils in the wet tropical coast of Queensland. 3. Basaltic soils

Abstract

Results of thirteen investigations into the fertility status of fifteen basaltic soils in the wet tropical coast of Queensland are presented. Although farming experience has shown these soils to be among the most fertile in the area, a widespread phosphorus deficiency is recorded. Plant growth responses to molybdenum, sulphur and calcium also occurred. The molybdenum deficiency appears to be particularly important in older , pastures where the initailly high soil nitrogen status has been depleted.
