Dalton et al. (1989b) utilizing Mehlich 111, a mild chelating extractant, also observed that the recovery of available phenolic acids (femlic acid, vanillic acid, p-coumaric acid, p-hydroxybenzoic acid) from sterile soil (Cecil, Portsmouth and White Store) varied with soil type, horizon, time, and the type of phenolic acid added. When they allowed phenolic acids added to soil to equilibrate for 2 min before extraction, they noted a significant reduction in recovery of phenolic acids. Recovery declined with time up to 32 days. The decline was most rapid over the first 2 days. The presence of methoxy groups and acrylic side chains increased... 

The bottles are removed from the shaker, and the soil suspensions are filtered through Whatman No. 1 filter papers. They may be analyzed immediately or stored at -18°C until required. On thawing, there is usually a white precipitate of calcium sulfate (CaS04) in the extracts. The bottles should be shaken thoroughly and then allowed to stand so that the precipitate settles out again before any extract is removed for analysis. The extracts are then refrozen in case repeat analyses are required. 

Microbial communities assimilate and recycle nutrients within the biomass pool as needed. Soils that maintain high microbial biomass are not only capable of storing more nutrients but also greater cycling within the system. Microbial biomass nitrogen (MBN) was higher in detrital and surface soil layers of the impacted site than the reference site (Reddy et al., 1999 White and Reddy,... 

Zinc is one of the most common elements in the earth s crust. Zinc is found in the air, soil, and water and is present in all foods. In its pure elemental (or metallic) form, zinc is a bluish-white shiny metal. There is no information on the taste and odor of metallic zinc. Powdered zinc is explosive and may burst into flames if stored in damp places. Metallic zinc has many uses in industry. A common use is as coating for iron or other metals so that they do not rust or corrode. Metallic zinc is also mixed with other metals to form alloys such as brass and bronze. A zinc and copper alloy is used to make pennies in the United States. Metallic zinc is also used to make dry cell batteries.
