Pseudo-sands are soil microaggregates with less than 1 mm diameter that are not dispersible in water even after 16 h of shaking treatment. The physical stability of pseudo-sands against dispersion may affect the extent to which organic matter is retained in the soil, particularly in Oxisols where ps...
