2019年2月11日 Soil aggregates, clusters of soil particles that adhere to each other more strongly than to surrounding particles, are one component of soil structure. Microbial activity is limited within...

Soil biota contributions to soil aggregation - Nature

2017年10月16日 The structuring of soil into distinct aggregates is a key element in biogeochemical cycling. Here, a meta-analysis reveals a strong positive effect of soil biota on

What are soil aggregates? - Soils Matter, Get the

2019年7月15日 Soil aggregates are formed through physical, chemical and biological activity below ground. They are even influenced by human factors, like tilling, walking on the surface, or even how you fertilize your garden.

Microaggregates in soils - Totsche - 2018 - Wiley

Soil aggregates are composite soil structures made of numerous aggregate forming materials. Soil aggregates can be classified into macro- and microaggregates. Macroaggregates comprises all soil aggregates > 250 μm,

Soil aggregate stability - Wikipedia

Soil sieve nests with dry soil aggregates after removal from a laboratory drying oven. Soil aggregate stability is a measure of the ability of soil aggregates—soil particles that bind together—to resist breaking apart when exposed to external forces such as water erosion and wind erosion, shrinking and swelling processes, and tillage. [1] [2] Soil aggregate stability is

Visualizing the dynamics of soil aggregation as affected by

2019年2月11日 Soil structure is a crucial ecosystem service important for maintaining soil porosity, gas exchange, water infiltration, erosion resistance, and carbon sequestration [1,2,3,4,5,6].Soil aggregates ...

Soil aggregates as massively concurrent evolutionary incubators

2017年4月14日 Soil aggregates have, however, so far been neglected when it comes to evolutionary considerations (Crawford et al., 2005) and we here propose that the process of soil aggregation should be ...

Aggregates are a part of soil structure and function

Soil organic matter holds aggregates together, making them stable and structural. At the same time, aggregates protect the organic matter from decomposition. Aggregates are broken down into microaggregates and macroaggregates; each class having specific benefits for soil health.

Soil Aggregates — Formation and Stability SpringerLink

The second requirement for crops other than rice is that waterlogging does not occur, and that soil aggregates at field capacity contain adequate porosity for storing water accessible to plant roots. To satisfy these requirements, aggregates in

Soil structure and microbiome functions in agroecosystems

2022年11月22日 Soil microbiomes drive key functions in agroecosystems, determining soil fertility, crop productivity and stress tolerance. The microbiome is intricately linked with soil structure, such as ...

Soil Aggregation in Relation to Organic Amendment: a Synthesis

2022年3月15日 Soil aggregation, a key aspect of soil physical health, is a crucial component of agroecosystem sustainability as it affects numerous soil processes and agroecosystem productivity. Application of organic amendment (OA) plays a vital role in improving soil aggregation. In this review, we provide a comprehensive synthesis and a critical assessment

Global Change Biology Environmental Change Journal - Wiley

Embedded in the soil matrix, soil aggregates exhibit physical, chemical, and biological properties that differ from the bulk soil (Figure 1). Soil aggregates contain a three-dimensional structure with pores of varying sizes (e.g., Ebrahimi Or, 2016). Organic matter becomes occluded during the aggregation process.

Process sequence of soil aggregate formation ... - ScienceDirect

2023年1月1日 The field-fresh soil used for the multi-isotope labelling incubation experiment comprised mainly microaggregates occluded in macroaggregates (>50 % of soil mass); however, 13.5 % of the soil aggregates resisted ultrasonic dispersion of 60 J mL −1 and thus ended up in the stable macroaggregate fraction (Table 2, bottom).

Soil Aggregation in Relation to Organic Amendment: a Synthesis

Microbial regulation of aggregate stability and carbon

2024年1月1日 There has been a dramatic increase recently in investigations into soil organic carbon (C) sequestration, as its storage contributes to soil fertility and climate change mitigation (Chowaniak et al., 2020; Lu et al., 2009).The essential function of soil aggregates in providing protection for the sequestration of soil organic C (SOC) has been widely appreciated.

Soil Aggregate Stability – a soil health physical indicator

Micro-aggregates are 20–250 μm in size and are composed of clay microstructures, silt-size micro-aggregates, humic materials, organic-metal bridging, and mycorrhizal fungus hyphae: these particles are stable in nature. Roots and microbes combine micro-aggregates to form soil macro-aggregates.

Soil aggregates, aggregate-associated carbon and nitrogen, and

2021年4月1日 Soil aggregates are formed through physical, chemical, and biological activities below ground, and these are the foundation of the soil structure (Andruschkewitsch et al., 2014; Bravo-Garza et al., 2010). In the present study, tillage management significantly impacted the soil aggregate size distribution.
