Soil Aggregation - an overview | ScienceDirect Topics
Soil aggregates are clumps of soil formed by physical, chemical, and biological activity below ground. Soil aggregation and structure have integral characteristics as they influence root distribution by affecting soil fertility, nutrients, and water comprehension.
Soil structure – Introduction to Soil Science
A soil aggregate, or conglomerate of sand, silt, clay, and sometimes organic material, may be a variety of different shapes. Structure is important because it allows critical areas of open space, vital for water to move, roots to grow, and soil organisms.
The subtle science behind soil aggregates - Successful Farming
2021年2月26日 — Tillage breaks aggregates apart and introduces air into the soil, stimulating microbes to increase the rate of organic matter decomposition. As soil loses organic matter to the atmosphere as carbon dioxide, less organic material is left to bind aggregates together.
Soil Aggregates, Structure, and Stability | SpringerLink
2014年1月1日 — 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 wetting by raindrops which cause aggregate disintegration.
Soil Aggregate - an overview | ScienceDirect Topics
Soil aggregates are stable structures composed of tiny mineral particles, used as indicators of the physiochemical properties and nutrients of the soil. They can be divided into large aggregates (sized>250 μm) and micro-aggregates (sized 50–250 μm).
Aggregation and Aggregate Stability - Soil Health Nexus
2019年10月1日 — Soil aggregate stability is an important physical indicator of soil health, which protects organic matter accumulation, improves soil porosity, drainage and water availability for plants, decreases soil compaction, supports biological activity, and nutrient cycling in the soil.
Aggregates are a part of soil structure and function - NDSU
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 biota contributions to soil aggregation - Nature
2017年10月16日 — Our study shows a clear positive effect of soil biota on soil aggregation, with bacteria and fungi generally appearing to be more important for soil aggregation than soil animals.

Soil structure and microbiome functions in agroecosystems
2022年11月22日 — In this Review, we summarize the key functions of soil microbiomes in agroecosystems, highlight the dependence of these functions on the structural integrity of the soil, and discuss how...
