Synonyms Soil clod; Soil stability; Soil structure Definition Primary soil particles held together by cohesive forces, secondary particles and organic matter, form soil aggregates. Stability of an aggregate is its ability to resist stresses such as tillage, swelling, and shrinking processes and fast ...

The present study was carried out to clarify the effects of some soil physical and chemical specifications on soil aggregates size distribution and stability under different tillage methods. Conventional tillage cause to break soil aggregates especially in loamy soils consequently increase soil sensitivity...
This study demonstrates how the fractal characteristics of soil structure and the stability of soil aggregates are crucial to better understanding karst rocky desertification. The fractal dimension of different land use patterns can be used to indicate the magnitude of soil destruction. Soil fractal ...
soil aggregates are, and the stronger the stability of soil structure is20. Castrignano and Stelluti21found that the larger the D value of soil aggregates are, the easier dispersed the aggregates were. The amount of soil micro-aggregates (WSA0.053-0.25 mm) increases with the increase of ...
soil carbon is essential to aggregate composition, structure, and stability. Soil aggregation is also involved in various processes like constriction of soil, nutrient cycling of soil, soil erosion, incorporation of the root, earning from a crop, and maintenance of soil structure, improving soil ...

The influence of landscapes and vegetation types on soil aggregate stability was studied at 55 sites in rangeland and 18 sites in cropland in northeastern Syria. For the measurement of soil aggregate stability, the wet-sieving test was applied to air-dried and prewetted aggregates. As soil prop...
Most soils break up naturally into some form of aggregates, as pictured in Figure 1. Important physical aspects of aggregates include their size, density, stability, structure, and their effect on the transport of fluids, solutes, colloids, and heat. Sign in to download full-size image ...
Our aim was to determine the effect of soil characteristics and root traits on soil aggregate stability at an inter- and intra-site scale in a range of agro-ecosystems. We also evaluated the effect of soil depth and the type of land use on aggregate stability. Soil aggregate stability, soil...
