collection of sub-samples is the first activity performed (i.e., pre-empting even the logging of sub-surface core sample recovery and other soil characteristics). If a second core is obtained before the first core has been logged, the logging of the first core should be set aside until the second core has been sampled. In some cases, this is a

mix the soil thoroughly. Be sure to break up the soil cores, and discard any stones and crop residue. For soils that are quite wet and contain significant amounts of clay, you may need to partially air-dry the soil prior to mixing the soil. Never dry your soil samples in a microwave or oven as this can damage the accuracy of laboratory analysis. 6.

Soil macro-aggregate characteristics can be addressed by describing aggregates, such as aggregate size distribution, mean weight diameter, and fractal dimension (Rabot et al., 2018). Dry soil retained in the various sieves was collected and weighed, and then the mean weight diameter (MWD) of dry-sieved aggregates was calculated using Eq.
