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;
