Macropores and water flow in soils and substrates are complex and are related to topics like preferential flow, nonequilibrium flow, and dual-continuum. Hence, the quantification of the number of macropores and the determination of their geometry are expected to provide a better understanding on the effects of pores on the soil's physical and hydraulic properties. This exploratory study aimed a...

• Tree species-specific root morphology influenced soil macroporosity and hydrology. fine altered hydrology independently of classification. Fine biomass differed by 6-fold amongst the seven tree species studied. Root necromass was best metric to predict hydraulic conductivity. Loss Fraxinus excelsior disease could have an impact on local Natural approaches flood risk management are gaining int...

The soil particles can be gathered through physical and/or chemical processes in association with the biological activity, leading to formation of aggregates. Soil aggregates has several functions soil, increasing macroporosity and water circulation – consequently reducing erosion mechanical resistance root growth, contributing greater fixation plants absorption nutrients, protection intra-aggr...

Restored prairies are expected to improve soil physical properties, yet little is known about the extent of change to soil properties and how rapidly these changes take place. The objective of this study was to compare effects of prairie restoration on computed tomography (CT)-measured pore parameters. Undisturbed soil cores (76 mm diam. by 76 mm long) from native prairie (NP), restored prairie...

Several contrasting uses of the terms macro(large) and micro(small) pore can be identified in soil science literature. In some cases macropores are (i) considered to be pores > 15 (Marshall, 1959) or 100 /im in diam (Bouma et al., 1977) or (ii) implied to be even larger when described in terms of wormholes (Ehlers, 1975), root channels (Aubertin, 1971). and shrinkage cracks (Lewis, 1977). The s...
