, 2020 Wildlands play a special role in providing a reliable supply of high-quality water (Dissmeyer 2000), and, in particular, we rely on forest and rangeland soils to ensure clean, abundant water. Soils retain water and make it available to support vegetation, facilitate drainage to soil and ultimately to surface waters (streams and lakes), and recharge ...

Heavy metals phyto-assessment in commonly grown vegetables: water spinach (I. aquatica) and okra (A. esculentus) [PDF]
, 2016 The growth response, metal tolerance and phytoaccumulation properties of water spinach (Ipomoea aquatica) and okra (Abelmoschus esculentus) were assessed under different contaminated spiked metals: control, 50 mg Pb/kg soil, 50 mg Zn/kg soil and 50 mg Cu/

Eos, Transactions American Geophysical Union, 1976 Water has been called ubiquitous, which may be a small exaggeration, but it is no exaggeration to say that it is intimately associated with soil. In the never‐ending hydrologic cycle, rain falls upon the soil, and whether the soil is shielded by vegetation or otherwise protected is much of what soil and water conservation is all about.The story of soil

Water withdrawal from deep soil layers: a key strategy to sustain growth during dry seasons in tropical Eucalyptus plantations [PDF]
, 2013 Little is known about the role of very deep roots to supply the water requirements of tropical forests. Clonal Eucalyptus plantations managed in short rotation on very deep Ferralsols are simple forest ecosystems (only 1 plant genotype growing on a ...

Possibilities of some methods for risk assessment of arsenic load in soils
Plant, Soil and Environment, 2008 The paper deals with the possibilities of arsenic analysis in the soil. The aim is the selection and verification of the methods for analysis of As in the soil, which seem to be suitable for risk evaluation based on the increased As soil load. Economical

Dark oxidation of water in soils [PDF]
Tellus B: Chemical and Physical Meteorology, 2013 We report the release of oxygen (O2) under dark conditions in aerobic soils. This unexpected process is hidden by respiration which constitutes the dominating reversal O2 flux. By using H218O in different soils, we confirmed that 16O18O and 18O2 released under dark soil conditions originated from added H218O.
