Soil microbial characteristics as bioindicators of soil health

Soil invertebrates as bioindicators of urban soil quality.

This study aimed at relating the abundance and diversity of invertebrate communities of urban soils to chemical and physical soil characteristics and to identify the taxa most sensitive or tolerant to soil stressors. The invertebrate community of five urban soils in Naples, Italy, was sampled. To assess soil quality invertebrate community indices (Shannon, Simpson, Menhinick and Pielou indices)...

Preliminary assessment of microbial-based soil additives

Soil Microbial Biomass Determination

Basic Idea: The quantity of microbial biomass in a given soil sample is inherently difficult to measure. To some degree, any measurement of microbial biomass is relative – different methodologies or variations in methodologies will yield microbial biomass estimates that are not directly comparable. For this reason, if you want to measure microbial biomass – choose a method and stick with it exa...

Changes in Soil Microbial Characteristics with Elevated Salinity

Changes in microbial characteristics in soils with increasing salinity were measured in 30 soil samples belonging to Kattikhel and Dargai soil series occuring in Khyber Pakhtunkhwa of North West Pakistan during 2009. Microbial characteristics including microbial biomass C, microbial biomass N, C/N ratio in microbial biomass, N mineralization, nitrification, rate of CO2 evolution and cumulative ...
