Relationship between Mineral Soil Surface Area and the Biological Degradation of Biosolids Added to Soil

Geochemical and biological processes that operate in the soil matrix and on the soil surface are important to the degradation of biosolids in soil. Due to the large surface area of soils it is assumed that the microbial ecology is associated with mineral soil surface area. The total mineral surface areas were determined for soils from eight different fields selected from a long term study (1972...

Biological degradation of PCBS in soil. A kinetic study

In this paper a kinetic study is made of the biodegradability of Aroclor 1242 in sandy soil employing a mixed culture of acclimatized bacteria. The assays were done in stirred tank reactors, and the biodegradation process was monitored by High Resolution Gas Chromatography (HRGC) with Electron Capture Detector. These results are supported by other indirect measurements and indicators of the exi...

Enhancing Soil Quality and Plant Health Through Suppressive Organic Amendments

The practice of adding organic amendments to crop soils is undergoing resurgence as an efficient way to restore soil organic matter content and to improve soil quality. The quantity and quality of the organic matter inputs affect soil physicochemical properties and soil microbiota, influencing different parameters such as microbial biomass and diversity, community structure and microbial activi...

The soil perfusion technique for the biological degradation of sulfite waste liquor.

Considerable attention has been given to chemical methods of reducing the Biochemical Oxygen Demand (B.O.D.) of semi-chemical neutral sulfite waste (S.N.W.). Very little study has been devoted to a biological method. The exact composition of this paper industry waste will vary with the type of wood chip used and the modification of cook. Table 1 shows a typical composition of the liquor resulti...
