2016-12-8 Soil Aggregates Aggregates are granules or clumps of soil made up of sand, silt, and clay glued together by organic matter (Figure 1). Soil structure refers to the size and shape of soil aggregates and the pore spaces between them, arranged in a layer of soil. Soil structure is an important indicator

2021-4-1 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.

In order to improve the quality of aggregates, limestone, dolomite and other materials with medium hardness and low SiO2 content are the first choice for the raw materials for aggregate processing. Second, choose hard and brittle stones such as granite and tuff. Try not to choose rocks with high compressive strength, toughness and abrasiveness ...

Improve Soil Structure Research in both the United States and Canada indicate improved soil physical properties following legumes. The improvements are attributed to increases in more stable soil aggregates. The protein, glomalin, symbiotically along the roots of legumes and other plants, serves as a “glue” that binds soil

2021-8-17 The combination of increased soil cover and SOC can improve soil structure and aggregation, thereby reducing soil susceptibility to wind and water erosion (Blanco-Canqui Ruis, 2020). Cover crops, especially grasses like triticale, can increase water-stable and dry aggregates compared to fallow (Table 2; Blanco-Canqui et al., 2013).

2021-10-13 Revealing the variation in soil aggregate-associated organic carbon (Corg) in tea plantations of various planting ages is crucial to shed more light on the accumulation and decomposition of soil Corg in the tea-planting period. This study measured the concentrations of soil Corg, active carbon (Cact), and recalcitrant carbon (Crec) in different-sized aggregates obtained from tea plantations of ...
