The depth at which plants are able to grow roots has important implications for the whole ecosystem hydrological balance, as well as for carbon and nutrient cycling. Here we summarize what we know about the maximum rooting depth of species belonging to the major terrestrial biomes. We found 290 observations of maximum rooting depth in the literature which covered 253 woody and herbaceous species. Maximum rooting depth ranged from 0.3 m for some tundra species to 68 m for Boscia albitrunca in… 

Do deep tree roots provide nutrients to the tropical rainforest?

The contribution of deep tree roots to the nutrition of a tropicalrainforest were studied along an edaphic transect in French Guyana. Soil typeswere mapped in relation to the texture of the upper

Deep root function in soil water dynamics in cerrado savannas of central Brazil

The results suggest that deep-rooted plants may contribute significantly to the water balance of cerrado ecosystems, and that the hydrological cycle of this biome could change as woody vegetation is replaced by exotic grasses and agricultural crops.

Biomass allometries and coarse root biomass distribution of mountain birch in southern Iceland

The study showed that coarse root biomass of mountain birch was almost exclusively located in the top 30 cm, even in a natural old-growth woodland, and provided allometric functions for a more accurate root biomass estimation to be utilized in inventory reports and ecological studies.

Rooting depth, water availability, and vegetation cover along an aridity gradient in Patagonia

Although water was accessible to roots in deeper soil layers in all habitats, as demonstrated by high soil moisture, earlier rain events were not fully utilized by the current plant cover during summer drought, and this study cannot explain the vegetation zonation along the transect on the basis of water supply to the existing plant cover.

Relationship between the structure of root systems and resource use for 11 North American grassland plants

Across all species and depths examined, there were strong relationships betweenthe amount of fine root biomass present in a unit of volume of soil and thedepletion of soil water and nitrogen, but there were no relationships with coarse belowground biomass.

Soil water availability and rooting depth as determinants of hydraulic architecture of Patagonian woody species

Study of the water economy of nine woody species differing in rooting depth in a Patagonian shrub steppe from southern Argentina found that shallow rooted species had efficient water transport in terms of high specific and leaf specific hydraulic conductivity, low ρw, high SLA and a low minimum ΨLeaf.

Dawn Water Potential and Root Depth of Trees and Understorey Species in Southwestern Australia

Water relations of selected tree and understorey species in the jarrah forest of south-western Australia were studied during summer drought and the results related to root morphology and measurements of Ψp, were consistent with a top-to-bottom drying of the soil profiles.

A global analysis of root distributions for terrestrial biomes

Rooting patterns for terrestrial biomes are analyzed and distributions for various plant functional groups are compared and the merits and possible shortcomings of the analysis are discussed in the context of root biomass and root functioning.

Vertical root distribution and strontium uptake of a slash pine stand on a Florida spodosol

Root length distribution of slash pine (Pinus elliottii Engelm. var. elliottii) and associated understory vegetation was investigated for an Ultic Haplaquod in north-central Florida. One-third of the

Aerial and Belowground Phytomass of Banksia Scrub-Heath at Eneabba, South-Western Australia

Three Banksia spp. accounted for 80% of the aerial biomass of scrub-heath on deep sand. Reproductive structures contributed relatively more than leaves or stems to biomass of a non-sprouting Banksia,

Root System of Quercus macrocarpa in Relation to the Invasion of Prairie

An ecotone between the grassland and the deciduous forest along the Missouri River occurs in southeastern Nebraska, and quercus macrocarpa is the most xeric forest tree, invading the grass land either directly or in the wake of the Rhus-Symphoricarpos-Corylus chaparral.
