Factors causing variation in fine root biomass in forest ecosystems
Forest Ecology and Management, 2011Abstract Fine roots form one of the most significant components contributing to carbon cycling in forest ecosystems. We study here the effect of variation in root diameter classes, sampling depth and the inclusion of understorey vegetation root biomass in fine root biomass (FRB) estimates.

Effects of nutrient amendments on fine root biomass in a primary successional forest in Hawai'i
Oecologia, 1989We determined the effect of fertilization treatments (control (C), complete nutrient amendment without nitrogen (PT), nitrogen only (N) and a complete nutrient amendment (NPT)) on fine root biomass in a tropical montane forest in Hawai'i. Fertilization significantly decreased root biomass; live fine root mass (

FINE ROOT BIOMASS AND PRODUCTION IN A SEMIARID MEXICAN SHRUBLAND
The Southwestern Naturalist, 2007Abstract I describe the vertical distribution of root biomass and root productivity in a xeric shrubland of central Mexico. The effect of the soil nitrogen on root production was evaluated with a fertilization experiment. The highest percentage of roots was found at a depth of 40 to 60 cm.

Rooting patterns and fine root biomass of Pinus pinaster assessed by trench wall and core methods
Journal of Forest Research, 2008Variability of fine root (diameter < 2 mm) distribution was investigated in four 55 to 56-year-old Maritime pine (Pinus pinaster) stands using a combination of trench wall observations and destructive sampling. Our objectives were to assess patterns of fine root distribution, to estimate tree fine root biomass and to explore interactions with ...

Fine-root (<2 mm) biomass and biomass distribution were determined in different age-classes of three European forest chronosequences dominated by Fagus sylvatica L., Picea abies (L.) Karst., and Quercus cerris L., respectively. Root samples were taken with the auger method.

Vegetatio, 1990
Quercus coccifera L., the characteristic scrub oak of the garrigue, covers more than 100,000 ha in southern France alone. Precipitation in this area averages 900 mm/year and summer rains are not rare. A total belowground biomass of 7.2 kg/m2, including rhizomes and lignotubers, was harvested.

Fine-root dynamics and biomass distribution in a Quercus ecosystem following harvesting
Forest Ecology and Management, 1989Abstract This study tested the hypotheses: i) that harvesting significantly affects fine-root biomass, production and mortality; and ii) that below-ground living plant biomass recovers to pre-harvest level more rapidly than above-ground biomass. Vertical distribution, temporal trends, production and mortality of fine-root biomass, and below-ground ...

Fine root longevity and biomass production in boreal peatlands
Drainage for forestry alters the carbon (C) dynamics and stocks of peatlands. After drainage soil C stocks usually decrease, because of increased soil organic matter (SOM) decomposition, while the C stocks in vegetation (trees) increase, because of increased primary production.Kari Minkkinen +2 more

Soil Carbon, Nitrogen, and Fine Root Biomass Sampling in a Pine Stand
Soil Science Society of America Journal, 1992Abstract Spatial variability of soil properties can be great in forested settings. A study was conducted to determine the most efficient methodology for sampling surface mineral soils in a mature loblolly pine ( Pinus taeda L.) forest for total C, total N, and fine root ...

Fine root biomass under light gap openings in an Amazon rain forest
Oecologia, 1990Belowground processes in light gap openings are poorly understood, particularly in tropical forests. Fine roots in three zones of light gap openings and adjacent intact forest were regularly measured in buried bags and surface litter envelopes for 2 years.
