Soil aggregate stability data are often predicted to be positively associated with measures of plant productivity, rangeland health, and ecosystem functioning. Here we revisit the hypothesis that soil aggregate stability is positively associated with plant productivity. We measured local (plot-to-plot) variation in grassland community composition, plant (aboveground) biomass, root biomass, % wa...

Recently, numerous studies of aggregate response to freezing have been reported. Aggregate stability has usually been inversely proportional to soil water content at the time of freezing (Bullock et al., 1988; Benoit, 1973; Bryan, 1971; Logsdail and Webber, 1959). Aggregates from poorly aggregated soils, however, are more stable when frozen at intermediate water contents (Mostaghimi et al., 198...

This article examines the impact of rice–wheat, maize–wheat and cotton–wheat cropping systems on total (TOC), labile stable organic carbon (C) pools, aggregate stability distribution C in different size aggregates mineral fraction (silt + clay) soil. The rice–wheat soils had significantly (p < .05) lower TOC concentration (4.46 ± 0.15 g kg−1) compared with other two systems. Similarly, water-ex...

Green manure, used for eco-friendly agriculture, supplies organic matter (OM) and nutrients to soil improves fertility. manuring also has the potential affect physical stability carbon storage. The objective of this study was investigate effect green manure on water-stable aggregates stock in paddy. Soil samples were collected from 3 treatments Chungcheongnam-do Agricultural Research Extension ...

The formation of water-in-water emulsions from the aqueous two phase system containing polyethylene oxide and pullulan, stabilised by montmorillonite platelets, was investigated. A novel approach of preparing the emulsions at non-equilibrium polymer concentrations was successfully utilised to control viscosity during mixing and allow the use of low energy emulsification methods. Polyethylene ox...

The formation and stabilization of soil aggregates play a key role in soil functions. To date, few studies have been performed on the variation of soil aggregation with increasing soil weathering degree. Here, soil aggregation and its influencing factors along the weathering gradient were investigated. Six typical zonal soils (derived from similar parent materials) were sampled from temperate t...
