Core Ideas Movement of O2 in the soil is mainly diffusive. Respiration consists of plant root
and microbial O2 uptake, roughly of the same magnitude. Reduced O2 and elevated CO2 …

Root systems of nearly all trees in the built environment are subject to impacts of human
activities that can affect tree health and reduce longevity. These influences are present from …

We examined the effects of air injection into clayey-soil, with and without a perforated sphere
around the dripper, on oxygen concentrations and pepper yields in a barrel experiment, and …

The soil around Quercus palustris trees, 30cm (11.8 in) average diameter breast height
(DBH) were treated by compaction (C) or C plus clay slurry (CS) treatments in November …

We extensively surveyed the soil aeration status in 35 commercial, drip-irrigated Israeli
orchards, mostly in 2007 and 2008. The main objective of the survey was to evaluate the …

Landscape trees are frequently planted with their root collars below grade, a practice that
may predispose them to transplant failure and girdling root formation. The objective of the …

Potato rates fourth among the world‟ s agricultural products in production volume (Faberio

The aim of this study was to investigate the effects of short-term tillage on soil bulk density
(BD), penetration resistance (PR), soil temperature (ST), electrical conductivity (EC), pH and …

Root flares of landscape trees are increasingly found to be much deeper than their forest
counterparts, indicating that their root systems have been situated deeper in the soil …

In urban forestry, the assessment and valuation of ecosystem services provided by urban
trees are increasingly important both for the rationale of planting new trees and for retaining …
