Specialised definition of the noun Macropore
Glossary of ecology
soil pore larger than 1 mm in diameter including interparticle void, earthworm or rodent burrow, drying crack, and decayed root channel
Macropore: In soil, macropores are defined as cavities that are larger than 75 μm. Functionally, pores of this size host preferential soil solution flow and rapid transport of solutes and colloids. Macropores increase the hydraulic conductivity of soil, allowing water to infiltrate and drain quickly, and shallow groundwater to move relatively rapidly via lateral flow. In soil, macropores are created by plant roots, soil cracks, soil fauna, and by aggregation of soil particles into peds.
