Soil biota contributions to soil aggregation. [PDF]

Nat Ecol Evol, 2017
Humankind depends on the sustainability of soils for its survival and well-being. Threatened by a rapidly changing world, our soils suffer from degradation and biodiversity loss, making it increasingly important to understand the role of soil biodiversity in soil aggregation-a key parameter for soil sustainability.

Fungal Traits Important for Soil Aggregation. [PDF]

Front Microbiol, 2019
Soil structure, the complex arrangement of soil into aggregates and pore spaces, is a key feature of soils and soil biota. Among them, filamentous saprobic fungi have well-documented effects on soil aggregation. However, it is unclear what properties, or traits, determine the overall positive effect of fungi on soil aggregation. To achieve progress, it

The role of conservation soil management on soil and water protection at different spatial scales [PDF]

, 2006
Agriculture has a direct impact on the soil environment, altering soil properties, surface characteristics and erosion risk. This has led to a move away from conventional tillage to the adoption of conservation practices, aiming to minimise soil ...

THE RELATIONSHIP OF POLYSACCHARIDES TO SOIL AGGREGATION [PDF]

Canadian Journal of Soil Science, 1963
Studies were conducted on two soil types to determine whether variations in level of aggregation, induced by adding wheat straw were accompanied by significant changes in the polysaccharide content of the soils.The addition of finely ground wheat straw to the soils, followed by varying periods of incubation, markedly improved the level of aggregation ...

Saving the face of soil aggregates [PDF]

Global Change Biology, 2019
Hierarchy levels and building units of micro- and macroaggregates and related separation methods. The hierarchy levels (left arrow) are inversely related to the energy necessary for the disruption (right arrow).

Importance of microbial communities at the root-soil interface for extracellular polymeric substances and soil aggregation in semiarid grasslands [PDF]

, 2021
In the past years, extracellular polymeric substances (EPS) produced by soil microorganisms received an increasing interest, as they not only protect microbes against environmental stresses, but seem to play a pivotal role in soil structure formation as ...

Contrasting effects of maize straw and its biochar on aggregation and soil organic matter stabilization

, 2023
Background and aims: Crop straw and it derived biochar are both promising to improve soil fertility and structure. However, the contribution of these amendments to microbial biomass and aggregate formation, as well as carbon (C) and nitrogen (N ...

Influence of the integrated crop-livestock system on soil and soybean and brachiaria yield

Pesquisa Agropecuária Tropical, 2015
The presence of animals in farming areas can affect soil physical structures depending on grazing intensity. This study aimed to evaluate soil physical attributes, as well as soybean and brachiaria yield, under no-tillage, in an integrated crop-livestock

Land use conversion to agriculture impacts biodiversity, erosion control, and key soil properties in an Andean watershed

Ecosphere, 2022
The conversion of natural vegetation to agricultural land uses in mountainous Andean landscapes threatens an array of key ecological processes and ecosystem services (ES). In protected areas and buffer regions that provide water to cities, it is critical

Pearl Millet Genetic Traits Shape Rhizobacterial Diversity and Modulate Rhizosphere Aggregation

Frontiers in Plant Science, 2017
Root exudation contributes to soil carbon allocation and also to microbial C and energy supply, which subsequently impacts soil aggregation around roots. Biologically-driven soil structural formation is an important driver of soil fertility.
