摘要：

This paper deals with nutrient dynamics in 2- to 8-year-old plantations of Eucalyptus tereticomis Sm. previously investigated for dry matter dynamics. The nutrient concentrations changed in the order: herb > shrub > tree. The nutrient concentrations in the different components of these vegetation types also decreased with plantation age. The nutrient content in trees and shrubs increased and in herbs it decreased with increase in plantation age. The uptake of nutrients by vegetation and also by components with or without adjustment for retranslocation, has been calculated separately. Turnover time for different nutrients ranged between 1-05 and 1 -35 years. Compartmental models for nutrient dynamics have been developed to represent the distribution of nutrient contents and net annual fluxes within the system. © 1992 Annals of Botany Company.
