Wetting and drying (W-D) cycles can induce important elemental migrations in soils. The main purpose of this work was to study the possible existence of soil chemical elemental migrations in samples submitted to repeated W-D cycles during evaluations of soil water retention curve (SWRC). The experimental measurements were carried out by Atomic Absorption Spectrometry (AAS) for Ca(2+), Mg(2+) an...

The tension phenomenon described herein occurs in a wide variety of porous materials, including sands, clays, agricultural soils and porous rocks. When some of the water is removed from a water-saturated porous system, the residual water evidently remains physically interconnected, judging from the fact that water can be transmitted through the system at reduced water content by suction. The re...

In this study, TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl)-oxidized nanocellulose superabsorbents are prepared using three different drying techniques: freeze-dried, and oven-dried at low high temperatures. The benefits investigated by evaluating the superabsorbent structure, composition application rate. absorption performance of is affected concentration type salts in soil water extracts. Ov...
