Webnoun Geology. an aggregate of soil particles held together by various constituents of organic matter: macroaggregates as a rule are larger than 250 micrometers in diameter and are usually found in untilled or otherwise undisturbed soil. Biochemistry. a visible aggregate of biological molecules. WebDec 20, 2024 · Variation partitioning indicated that the formation of large macroaggregates was controlled by the litter-moss-root interactive effect in this karst area. FG could be a better short-term cropland restoration strategy, increasing large macroaggregates in deeper soil layers better than the other vegetation types and promoting soil carbon ...

WebThe stable macroaggregates were richer in total C and in young C (younger than 6 and 23 years respectively in the two soils studied) than the unstable ones. This young C comprised 50% particulate organic matter, 20% associated with silt and 30% with clay particles. We propose a schematic composition of aggregates in these soils in which stable ... WebMacroaggregates: Soil aggregates greater than 250 micrometers in size consisting of microaggregates cemented together by organic matter, microbial polysaccharides, fungal hyphae, earthworm excretions, and plant roots. Macroaggregates are typically found in undisturbed soils such as continuous no-till with cover crops.
