Abstract:

Correlation analysis was conducted using stem samples collected from Eucalyptus trial stands. A negative linear correlation between the reciprocal of nutrient concentration and the total amount of nutrient uptake in tree stem was observed for the three tested elements, nitrogen, phosphorus and potassium. Based on this linear relationship, the site productivity potential and the nutrient productivity parameter, as well as the site & nutrient effect curves were determined using the measured data with relatively high level of accuracy. The present study provides a new way for approach to the dynamic functional relationship between forest growth and nutrition.

Key words: Eucalyptus ABL12, Nutrient concentration, Nutrient uptake, Nutrient productivity parameter, Site productivity limit
