Wetting angle and water sorptivity in mineral soils
sub-critical repellency Washburn theory wavy capillary
2015/2/3
Two simple models of a non-cylindrical (wavy) capillary have been applied to show the impact of pore shape and of wetting angle on water sorptivity in soils. Wetting angle derived from the Washburn ap...
Effects of soil moisture and length of irrigation on soil wetting to deliver fumigants through microirrigation lines in sandy spodosols
Methyl Bromide Drip Irrigation Soilborne Pests Water Management
2013/3/5
Soil fumigant delivery through microirrigation (drip) lines has the potential to replace direct soil injection into planting beds. However, wetting coverage in these Spodosols must be improved to incr...
Effects of Wetting Treatment Period and Moisture Content on Water Uptake by Wheat Grain During Germination and α-amylase activity
α-Amylase activity Germination Grain Moisture content Preharvest sprouting Water uptake Wheat
2009/7/21
To vary the moisture content in wheat grain from 20 to 45%, various quantities of water were instilled in non-dormant grains in two varieties and one pedigree(Chihokukomugi, Horoshirikomugi and Kitake...
Hysteresis between wetting and drying processes as affected by soil aggregate size
soil aggregation water retention curve
2008/11/18
The impact of different sizes of soil aggregates on
the hysteresis of their water retention characteristics was determined.
Soil aggregates were separated from the arable layer of Orthic

Relative humidity and wetting affect friction between apple and flat surfaces
coefficient of friction humidity water dipping apple
2008/11/18
The objective of this study was to determine the influence of relative humidity and dipping in water on the static and dynamic coefficients of friction of apple on four surface types. Knowledge of the...

Influence of the cross-section shape in the capillaries on the wetting properties demonstrated by the calculated wetting angles
capillary rise capillary cross section wetting angles
2008/11/14
Earlier results had shown that the contracting force of water films between parallel solid surfaces increased when they were deformed to give longer menisci by subdividing the water volume. Since defo...
The analysis of shrinkage-swelling behaviour of peat-moorsh soil aggregates during drying-wetting cycles
peat-moorsh soil drying shrinkage rewetting swelling
2010/1/15
The aim of this study was to investigate the soil volume changes for moorsh, willow and moss peat layers during drying-wetting cycles. The measurements of soil volume changes were made using the ‘sara...
