Soil quality - Laboratory methods for determination of microbial soil respiration

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.

Soil quality - Laboratory methods for determination of microbial soil respiration

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
