Measurements of root respiration were conducted on undisturbed root systems by passing humidified air with 1000 mu l l(-1) CO2 through root boxes onto an infrared gas analyzer.
The objective was to understand the effects of N on soil respiration by examining total root respiration rate per seedling, specific root respiration rate g(-1) root dry wt, and root dry wt after N fertilization.
The increase of total respiration rate with the increase in N concentration from 10 to 50 mg l(-1) was attributed to the increase in specific respiration, whereas the subsequent decrease in total respiration with the increase in N concentration from 50 to 200 mg l(-1) was attributed to the decrease in root dry wt.
In order to obtain root samples, a horizontal outcrop was done using the method of monoliths in the profile of a transversal transect adjacent to the tree basis.
Roots from the monoliths were rinsed on sieves and scanned with the CCD Oskar camera at the resolution of 600 x 800 pixels.
The results of measurements have shown that beech roots in the control locality penetrated to a greater depth of the soil profile and total active surface of beech roots was larger in the limed locality.
