(2004) found that macroaggregates
were not controlled by the stable fraction of organic matter in the finer fractions (<20 [micro]m) but by those in >20 [micro]m fractions.
Large soil macroaggregates
would be built around smaller ones and bound together, first by root and microbial exudates and fine roots and fungal hyphae, on the outer parts of these aggregates.
The clay content offered little or no contribution to the macroaggregate
stability, except in WSA class 1-0.50 mm.
Presence of intrapulmonary shunting with a twodimensional contrast echocardiography or a Technetium-99 macroaggregate
albumin nuclear test should be documented.
The illuvial accumulation of clay on the vertical macroaggregate
surfaces of B horizons and formation of Argic diagnostic horizon were observed in these soils.
Indeed, at one level one may argue that explanation generated through macroaggregate
data on individual or group behavior raises serious ethical and methodological problems because by disregarding the actor's explanation, we are denying the individual's or group's ordinary right of being a responsible moral agent.
In addition, decreased macroaggregate
turnover under NT compared with CT stabilises particulate organic matter (POM) in microaggregates formed within water-stable macroaggregates
(Six et al.
On the contrary, there were also reports showing that recombinant peptides of thrombospondin could inhibit platelet aggregation as well as platelet macroaggregate
formation (Rabbi-Sabile et al., 1996; Legrand et al., 1994).
Effect of time and air-drying on macroaggregate
>2 mm stability (Expt 3)
Clay mineralogy determines the importance of biological versus abiotic processes for macroaggregate
formation and stabilization.
