标准范围

ISO 16702:2002描述了测定需氧非饱和土壤的土壤微生物呼吸的方法。所述方法适用于测定添加底物后(底物诱导的呼吸)或不添加底物(基础呼吸)的O2摄取或CO2释放。ISO 16702:2002适用于土壤呼吸的测量，以便:测定土壤中的微生物活性（见[2]）；建立添加剂（养分、污染物、土壤改良剂等）对微生物代谢性能的影响；测定微生物生物量（见[3]）；测定代谢商qCO2。

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.
