European Journal of Remote Sensing, 2023 Relative soil water content (RSWC) is widely used to characterize the impact of water stress (WS) on vegetation. In bi-layer ecosystems, such as olive groves, this impact must be primarily estimated for the tree component, which, having greater rooting ...

Scientific Reports, 2021 Plant rooting strongly affects most hydrological, biogeochemical and ecological processes in terrestrial ecosystems, as it presents the main pathway for carbon, water and nutrient transfer from soil to the atmosphere and is a key factor in stabilizing ...

Ecosystem rooting depth determined with caves and DNA [PDF]
Proceedings of the National Academy of Sciences, 1999 Belowground vertical community composition and maximum rooting depth of the Edwards Plateau of central Texas were determined by using DNA sequence variation to identify roots from caves 5–65 m deep. Roots from caves were identified by comparing their DNA sequences for the internal transcribed spacer (ITS) region of the 18S–26S ...

Distribution of root system of hop plants in hop gardens with regular rows cultivation
Plant, Soil and Environment, 2020 Spatial distribution of the root system of hop (Humulus lupulus L.) in the soil profile is a less explored issue. However, it is known that it can play an important role in the development of new tillage technologies, fertilisation and irrigation ...

Variation in sugar maple root respiration with root diameter and soil depth [PDF]
Tree Physiology, 1998 Root respiration may account for as much as 60% of total soil respiration. Therefore, factors that regulate the metabolic activity of roots and associated microbes are an important component of terrestrial carbon budgets. Root systems are often sampled by diameter and depth classes to enable researchers to process samples in a systematic and timely ...

Root Pruning and Planting Depth Impact Root Morphology in Containers [PDF]
Journal of Environmental Horticulture, 2012 Increasingly, producers and consumers are realizing that roots play a major role in nursery tree quality. To remain competitive, producers need to find economically viable methods of increasing quality standards. Two studies were designed to test methods of improving root systems in a container root ball.

Solving polynomials by radicals with roots of unity in minimum depth [PDF]
Mathematics of Computation, 1999 Summary: Let \(k\) be an algebraic number field. Let \(\alpha\) be a root of a polynomial \(f\in k[x]\) which is solvable by radicals. Let \(L\) be the splitting field of \(\alpha\) over \(k\). Let \(n\) be a natural number divisible by the discriminant of the maximal abelian subextension of \(L\), as well as the exponent of \(G(L/k)\), the Galois ...

Small differences in root distributions allow resource niche partitioning
Ecology and Evolution, 2020 Deep roots have long been thought to allow trees to coexist with shallow‐rooted grasses. However, data demonstrating how root distributions affect water uptake and niche partitioning are uncommon.
