water stable
The content of water stable aggregates in 18-year-old shrub land soil is higher than the 8-year-old shrub land, and the big aggregates (>amp;gt;5 mm) increased for the most part, by 67.4% and 59.0% in different layers, respectively.
      
The number of soil granular aggregates or the water stable aggregates under corylus clusters is more than that under the non-corylus clusters.
      
The influence of earthworms was determined by comparing soil aggregates and casts with respect to dry and moist porosity, swelling, and water stable aggregation.
      
In low P soils, however, a positive relation between the abundance of water stable soil aggregates in the 0.5-2?mm diameter range and RTI was most important.
      
The influence of water stable aggregation of soil on RTI was modulated by soil P levels.
      
The study of their properties revealed that these molecules are soluble in water (stable at pH?8) and show surface activity with similar low critical micelle concentration values.
      
The performance of ethanol and, to a lesser degree, other alcohols, suggests the existence of a water stable structural organization between CCl4 and these amphiphilic vehicles, facilitating the transfer of CCl4 to the membrane.
      
Three ice cores and a set of snow pit samples collected on James Ross Island, Antarctic Peninsula, in 1979, 1981 and 1991 have been analyzed for water stable isotope content δD or δ18O (isotopic temperature) and major chemical species.
