Spatial patterns of wetting characteristics in grassland sandy soil

Journal of Hydrology and Hydromechanics, 2016
In grasslands where organic and inorganic resources are alternating at scales of individual plants, the transient character is given to certain wetting properties of soil, which then become highly variable both in space and in time.

Solid-state structure of copper complexes of N-(2-carboxyethyl)chitosan [PDF]

, 2008
The sorptivity for ions of the Irving-Williams series (Zn2+, Cu2+, Co2+, Ni2+) was estimated for the chelate sorbent N-(2-carboxyethyl)chitosan cross-linked by nanosecond electron-beam irradiation.

Estimation of Soil Hydraulic Properties Curve through Beerkan Infiltration Experiment Algorithms

علوم آب و خاک, 2019
Nowadays, the Beerkan computational algorithms (BESTslope and BESTsteday) are known as the suitable indirect methods for estimating soil saturated hydraulic conductivity (Ks) and sorptivity (S), as well as the scale parameter (hg) in van Genuchten soil ...

Does no-till cover crop influence in situ measured soil water potential and saturated hydraulic conductivity?

Soil and Water Research
Soil water energy determines soil water balance, plant water uptake, and soil thermal properties, but the effects of cover crops (CCs) on in situ measured soil water energy and temperature are not well understood.

Fission Product Sorptivity in Graphite

, 2015
Both adsorption and absorption (sorption) of fission product (FP) gases on/into graphite are issues of interest in very high temperature reactors (VHTRs). In the original proposal, we proposed to use packed beds of graphite particles to measure sorption at a variety of temperatures and to use an electrodynamic balance (EDB) to measure sorption onto ...
