Acid soils play an important role in the production of world food and fibre. The majority of
acid soils in the tropical and subtropical regions are highly weathered, subject to intensive …

The study evaluates and compares two procedures for selecting soil quality indicators (used
for the construction of soil quality indices, SQI) by using diverse chemical, physical, and …

Soil biochemical properties are indicators of soil quality, but there is still no consensus as to
how they should be used. We review the trends in their use over the last decade. Generally …

The quality of soil can impact land use, sustainability, and productivity. Human and animal
health is closely linked to soil productivity and environmental quality. Soil microbial …

Microbial biomass carbon (C) and nitrogen (N) can be estimated by converting cell counts
and their estimated C, N, and water content to biomass C and N equivalents. The …

The concept of soil quality gives rise to more controversy than that of water or air quality.
However, despite the difficulty in providing a definition, the maintenance of soil quality is …

The aim of this study was to examine interrelationships between functional biochemical and
microbial indicators of soil quality, and their suitability to differentiate areas under contrasting …

The alarming paucity of information on biological indicators of soil quality and methods for
integrating physical, chemical, and biological soil properties with soil management practices …

The present review is focused on microbiological methods used in agricultural soils
accustomed to human disturbance. Recent developments in soil biology are analyzed with …

Environmental quality is a complex concept. Defining one component of it, soil quality, is
therefore usually attempted using indicators that represent, with differing levels of …
