EFFECTS OF FREEZING ON AGGREGATE STABILITY OF SOILS DIFFERING IN TEXTURE, MINERALOGY, AND ORGANIC MATTER CONTENT by
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...
متن کاملaggregate distribution of organic c, l-glutaminase activity and aggregate stability as affected by slope position
the location of extracellular enzyme activities in soil aggregates can be influenced by slope position. this study aims to determine the effect of slope position on aggregate distribution of organic c and l-glutaminase activity. the soils were collected from different slope positions (shoulder, backslope, footslope and toeslope) at two pasture ecosystems (fereydoonshahr and chelgerd, central ir...

متن کاملAggregate Stability and Water Retention near Saturation Characteristics as Affected by Soil Texture, Aggregate Size and Polyacrylamide Application
Understanding the effects of soil intrinsic properties and extrinsic conditions on aggregate stability is essential for the development of effective soil and water conservation practices. Our objective was to evaluate the combined role of soil texture, aggregate size and application of a stabilizing agent on aggregate and structure stability indices (composite structure index [SI], the α and n ...
متن کاملDetermination of Soil Aggregate Stability in Different Types and Amounts of Organic Matter in Khuzestan Plain, Iran
In soils under wheat cultivation, soil aggregates stability is increased and destructive effects of erosion decreased, due to organic matters (OM) application. This trail was conducted in Shavoor agriculture research station to determine of mean weight diameter (MWD) under different organic matter sources and amounts in Khuzestan province (at south west of Iran) via a split plot experiment base...
