Abstract:
Soil phosphorous and pH in three-tree groups in the Comparative Study sites.
29°08'-29°17'N
118°02'-118°11'E
Design:
Three trees are used as minimal neighborhood to study neighborhood effects on soil phosphorous
Spatial extent:
Comparative Study Sites
29°08'-29°17'N
118°02'-118°11'E
Temporal extent:
No information available
Taxonomic extent:
Soil samples are later related to the tree species of the three trees making up the three tree group.
