Effective Nutrient management for trees

摘要

Effective nutrient management for trees begins with an understanding of their natural habitat and how they obtain their mineral nutrients. This includes understanding differences between the natural habitat and the landscapes into which trees are planted. Of course, woodlands are the natural habitat for most if not all of the tree species that are used as street trees, ornamental trees and shade trees. In a woodland habitat, two features standout: one is the existence of an organic layer on the soilsurface; the other is the limited competition between trees and ground flora.
