Soil aggregate distribution by dry sieving: a practical guide for comparing crop management practices
(CIMMYT, 2013)
From a physical perspective, the soil matrix is generally conceptualized as being constituted by soil aggregates (filled spaces) or secondary soil units, and pores (empty spaces) (Soil Science Society of America, 1997; Lal ...
