Soil organic matter ResearchOnlineJCU

Research pertaining to the organic fraction of soils can be traced back in excess of 200 years. Achard (1786) isolated a dark amorphous precipitate upon acidification of an alkaline extract from peat. The effect of organic matter on soil N fertility (Liebig, 1840), and studies on the use of animal manures for maintaining soil fertility (Lawes, 1861) and the influence of soil and tree species ...

What Is The Impact Of Manure On Soil Organic Matter?

In addition, any benefits from soil organic matter are easily negated if soil compaction results from application on unfit soils. Building Soil Organic Matter With Manure Applying manure to the soil will provide other benefits, such as a greater diversity and activity of organisms and better soil structure.

Bromine has been proposed as a useful proxy for marine organic carbon, since bromine is more concentrated in marine organic matter compared to terrestrial organic matter. Here, we present a highresolution Quaternary record of marine organic carbon in the hemipelagic sediments of the Japan Sea obtained during Integrated Ocean Drilling Program (IODP) Expedition 346.

Results showed that the bromine utilization in DBPs formation was positive related with reaction time, pH and temperature. On the other hand, the bromine substitution factors (BSFs) of DBPs were generally increased with pH (except triHAAs) and bromide concentration, but decreased with the reaction time, temperature and chlorine dose.
