Results indicated that SOM in slakingresistant aggregates was not a homogeneous pool, but consisted of size/density fractions exhibiting different composition and stability. The properties of these fractions were influenced by the aggregate size.

The fractionation of waterstable aggregates and density fractionation may thus be helpful for an improved understanding of carbon dynamics affected by soil management, since aggregate and density fractions are more sensitive to changes in soil management than total OC (Oades 1988; Pikul et al. 2007; Puget et al. 2000; Von Lützow et al. 2006).

The arrangement and organization of soil particles in the soil, and the tendency of individual soil particles to bind together in aggregates; Aggregation creates intraaggregrate and interaggregate pore space, thereby changing flow paths for water, gases, solutes and pollutants; Effects on plant growth operates through: 1. Aeration 2. Soil compaction 3.

D13C enrichment of the SOM fractions showed that the main direction of C flows within the aggregates and SOM fractions was from the macroaggregatefree POM to the mineral microaggregate fraction. This confirmed the earlier concept of SOM turnover in aggregates, but for the first time quantified the C flows within the aggregates and SOM density ...

2012 71 A "golden rule " of compaction testing is: The proctor used to calculate percent density must match the soil being fact is restated here because it is the single factor why plus 4 corrections are necessary.

At the maize site the percentage of maizederived C was smallest in the fraction < 53 µm with 24% and steadily increased with increasing aggregate size to 47% in the fraction > 1000 µm. The major part (8691%) of the SOC was associated with the heavy mineral fraction at the grassland, maize and wheat site.

The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of while dry ammonium sulphate has a sg of (1130 kilograms/cubic meter).
