Variation in the soil water and soil air contents associated with a vegetation-soil sequence in the Tararua Mountains, New Zealand.

This paper describes part of a study of vegetation/soil system dynamics in which close relationships were demonstrated between structural change of the forest, with associated changes in composition, and changes in organic matter and soil physical properties, particularly the quantities of water and air in non-capillary pores. Because of these results an analysis was made of the quantities of water and air in the same soils under field coniditions to test their correspondence with the vegetation pattern and known physical properties
