INCIPIENT FAILURE OF SOIL AGGREGATES
Journal of Soil Science, 1962Summary A comparison of the rate of wetting of aggregates taken from a virgin and continuously cultivated Red‐brown Earth has been made. The aggregates were placed on a glass sinter which was connected to a horizontal capillary. The rate of water uptake was obtained from the rate of meniscus travel as water was adsorbed from the ...

Soil Aggregates — Formation and Stability
1990The first requirement for the efficient production of most agricultural crops is that sufficient water derived from rainfall or irrigation is accepted by the soil. Otherwise, water is not only wasted, but erosion may result. The second requirement for crops other than rice is that waterlogging does not occur, and that soil aggregates at field capacity ...

FRACTAL DIMENSION OF SOIL AGGREGATES
Soil Science, 1995Researchers have used scale-invariant bulk density, ρ, to estimate values of fractal dimension, D, for soil aggregate fragmentation. Justification for this assumption has not been fully explored. The objectives of this study were to compare values of D obtained using (i) scale-invariant and scale-variant ρ and (ii) linear (defined D l ) and nonlinear ...

Soil aggregates and humus systems
2016The survey of few main morphological soil aggregates (with intrinsic biological, chemical and physical contents) reveals the existence of different humus systems. Recognizable by naked eyes in the field, each humus system is confined in an ecological frame (climate, vegetation, substrate and soil) and results from a specific process of plants and soil ...

Microorganisms and Soil Aggregate Stability
1985A soil aggregate has been defined as “a naturally occurring cluster or group of soil particles in which the forces holding the particles together are much stronger than the forces between adjacent aggregates” (Martin et al., 1955). The terms soil structure and soil aggregation are often used synonymously, but soil aggregates are the basic units of soil
