The percentage of water-stable aggregates >amp;gt;1.0 mm was significantly reduced under bare fallow ( = 27.7%) compared with soils under vegetative cover = 79.3%).
      
The correlation between water-stable aggregates >amp;gt; 1.0 mm and exchangeable aluminum was negative and significant (r = -0.705°) at p = 0.05.
      
Root length, soil glomalin, and percent cover contributed equally strong paths to water-stable aggregation.
      
We tested the effects of plant species, fertilization and elevated CO2 on water-stable soil aggregation.
      
Elevated CO2 and NPK fertilization altered many of the factors known to influence aggregation, but did not affect water-stable aggregation at either depth, in any of the plant treatments.
      
Soil samples were collected from the 0- to 5-, 5- to 15- and 15- to 30-cm depths in order to determine particle size distribution, bulk density, water-stable aggregates, mean-weight diameter and soil moisture retention.
      
The water-stable aggregates (>amp;gt;2?mm), of 5-8?mm aggregates, were higher in RMS-forest by 24%, 90%, 66%, and under RMS-hay by 13%, 74%, 43% for the 0- to 5-, 5- to 15-, and 15- to 30-cm depths, respectively, than that under undisturbed forest.
      
The reclamation of mine soils with forest and hay improved surface soil bulk density and cone index, and enhanced water infiltration capacity and water-stable aggregates at the lower depths.
      
Water-stable Fe3+-HA complexes prepared in the laboratory were partially stable agains H+ and metal ion exchange reactions, whereas Cu2+ and Mn2+ in laboratory-prepared, water-stabl HA complexes were desorbed almost completely by these two reactions.
      
To assess the potential of P loss in runoff in relation to soil P status, the chemical nature and distribution of soil P in different size classes of water-stable aggregates were quantified for two distinctive soil types.
      
This type of α-nucleophile secures effective cleavage of water-stable substrates not only in alkaline but also in neutral and acidic media.
      
Generation of water-stable soil aggregates for improved erosion control and revegetation success.
      
In subsequent experiments we used a similar approach with biocides and measured water-stable aggregates.
      
Recently deposited organic protection of organic matter within soil macroaggre in soil water-stable aggregates.
      
Soil RespirationThe MWD of the water-stable soil aggregates was calculated as an integrated representation of the degree of aggregation.
