water-stable
Sludge depth, organic-matter content and water-stable aggregates were not significantly different from controls in E.
      
One year after treatment, soil samples were wet-sieved and water-stable aggregate size-class arrays were determined.
      
The content of water-stable aggregates of worm casts decreased in the following order:Dactyladenia sp.>amp;gt;Treculia sp.>amp;gt;Senna sp.>amp;gt;Leucaena sp.>amp;gt;Gliricidia sp.
      
The crop residues and soil texture had a significant effect on the water-stable aggregates formed after 8 weeks of treatments.
      
Significantly greater water-stable aggregates were formed in the sandy clay loam than the loamy sand.
      
Approximately 20% greater water-stable aggregates were formed under the crop residue treatments compared to the fertilizer only treatment.
      
Water-stable aggregates and associated organic matter in forest, savanna, and cropland soils of a seasonally dry tropical region
      
and Trappe] and a rhizobacterium (Bacillus sp.) on nitrate-fertilized or nodulated pea (Pisum sativum L.) plants and on the status of water-stable soil aggregates.
      
The rhizobacterium enhanced the water-stable aggregate status in the non-VAM soils only.
      
Under both N-nutrition regimes, the soils had the greatest proportion of the water-stable aggregates when inoculated with both rhizo-organisms and the lowest when colonized by neither.
      
The soils were sampled at 3-week intervals to determine changes in water-stable soil aggregates (WSA), soil pH, the development of roots, arbuscular mycorrhizal (AM) soil and root colonization, and selected functional groups of soil bacteria.
      
The ratio of bacterial counts in the water-stable versus water-unstable soil fractions increased for the first 6 weeks and then declined, while counts of anaerobic bacteria increased with increasing WSA.
      
The data demonstrated that aggregates supplemented with a source of C (millet or lentil straw) were much more water-stable and resisted microbial decomposition longer than when they were prepared with fungal homogenates alone.
      
Compost reduced soil bulk density and soil impedance, while increasing water-stable aggregates and improving infiltration.
      
Water-stable fluorophores, produced by reaction with aldehyde solutions, for the histochemical localization of catechol- and ind
      
Up to 98% of Boston blue clay was converted to water-stable aggregates by 4% of pitch.
      
Pools of total C in bulk soil and in water-stable aggregates (WSA) increased 1.5- and threefold, respectively, between the 250- and 650-ppm treatments.
      
We hypothesized long-term tillage and cropping system treatments affect water-stable aggregate size distribution, aggregate water stability, and dry soil aggregation.
      
In 1994, mean percentages of >amp;gt;4-mm water-stable aggregates at 0 to 2 cm were 3.5 with NT and 1.0 with SMT in wheat, sorghum, fallow, rotation phase, or crop comparison plots.
      
This coincided with higher values for fungal biomass, particulate organic matter carbon (POM-C), mean weight diameter of water-stable aggregates (MWD), and total organic carbon (TOC).
