Formation of Soil Aggregates and Accumulation of Soil Organic Matter

2020
Soil structure is the arrangement of particles in soil and the particles of sand, silt, and clay, bound together into aggregates of various sizes by organic and inorganic materials. The structural stability is the ability of the aggregates and pores to remain intact when subjected to stress, e.g. when aggregates are wetted quickly.

The Accumulation of Soil Organic Matter from Wood Chips

Soil Science Society of America Journal, 1953
Abstract A study was made in cylinders to measure the effect of incorporating 10 tons of pine and oak chips per acre to a Merrimac sandy loam. The influence of such factors as level of nitrate nitrogen, soil reaction, and size of wood chips, were investigated. Using nitrate nitrogen depression as a measure of rate of

Oceanographic controls on the accumulation of organic matter in marine sediments

Geological Society, London, Special Publications, 1987
Summary The concentration of organic matter in marine deposits depends on the relative rates of accumulation of the various sedimentary components and the ease with which these components are preserved after burial. The supply of organic matter to any area of sea floor is controlled by the primary production rate in the surface ocean and the ...

Survey on organic matter accumulation in the Anzali Lagoon sediments

1996
Organic matter was determined in different parts of lagoon sediments during three years with annual average Of 137.32 ± 28.60 milligram in one gram dried sediment. Seasonal and horizontal fluctuations range was very clear and varied between maximum amount in emergent macrophytes region (in March, 250.00 mg/g.
