ISO 16072:2002 PDF

ISO 16702:2002 describes methods for the determination of soil microbial respiration of aerobic, unsaturated soils. The methods are suitable for the determination of O₂ uptake or CO₂ release, either after addition of a substrate (substrate-induced respiration), or without substrate addition (basal respiration).

ISO 16702:2002 is applicable to the measurement of soil respiration in order to:

• determine the microbial activity in soil (see [2]);
• establish the effect of additives (nutrients, pollutants, soil improvers, etc.) on the metabolic performance of microorganisms;
• determine the microbial biomass (see [3]);
• determine the metabolic quotient qCO₂.
