1 INTRODUCTION. Soil aggregates consist of individual soil particles and organic matter that are cemented together, and are the units that form the soil structure (Alagöz & Yilmaz, 2009; Sarker et al., 2018; Six et al., 2002).The size, shape and stability of soil aggregates have a direct impact on soil aeration and water efficiency, which are …

Aggregate Sizes
Aggregate materials are generally broken up into two classifications of size: fine and coarse aggregate. Coarse aggregates are typically sizes larger than the #4 sieve. Fine aggregates are typically sizes smaller than the #4 sieve. What people refer to as "dust" is typically aggregate smaller than the #200 sieve. Simple enough right?

Sieve Sizes: A Guide to U.S. and Metric Sizes
Mineral aggregates for use in asphalt and concrete mixes are classified as coarse or fine. Coarse sieve sizes include sieves with openings larger than 4.75mm (No. 4), and fine sieve sizes are smaller than 4.75mm (No. 4), ranging down to 75µm (No. 200). The table below includes fine and coarse aggregate sieve sizes.

The increased soil aggregate stability and aggregate
Land use, soil depth and aggregate size had significant effects on the SOC content in bulk soil and in each soil aggregate (Table 2). The SOC content in bulk soil and in soil aggregates at the 0–10 cm depth were significantly higher than those at the 10–20 cm depth under BA and ORO (Fig. 3). Irrespective of the bulk soil and soil aggregates ...
