Moderate drought alters biomass and depth distribution of fine roots in Norway spruce

Popis výsledku v původním jazyce

A rain shelter experiment was conducted in a 90-year-old Norway spruce stand, in the Kysucke Beskydy Mts (Slovakia). Three rain shelters were constructed in the stand to prevent the rainfall from reaching the soil and to reduce water availability in therhizosphere. Fine root biomass and necromass were repeatedly measured throughout a growing season by soil coring. We established the quantities of fine root biomass (live) and necromass (dead) at soil depths of 05, 515, 1525 and 2535cm. Significant differences in soil moisture contents between control and drought plots were found in the top 15cm of soil after 20weeks of rainfall manipulation (lasting from early June to late October). Our observations show that even relatively light drought decreased total fine root biomass from 272.0 to 242.8gm2 and increased the amount of necromass from 79.2 to 101.2gm2 in the top 35cm of soil. Very fine roots (VFR), that is, those with diameter up to 1mm, were more affected than total fine roots defin
