Soil quality - Determination of soil microbial biomass - Part 1: Substrate-induced respiration method (ISO 14240-1:1997)

This part of IS0 14240 specifies a method for estimating the active aerobic, heterotrophic microbial biomass in aerated agricultural and mineral soils. Determination of the effects of chemicals on biomass is outside the scope of this part of IS0 14240.

Bodenbeschaffenheit - Bestimmung der mikrobiellen Biomasse von Böden - Teil 1: Substrat-induziertes Respirationsverfahren (ISO 14240-1:1997)

Dieser Teil von ISO 14240 legt ein Verfahren für die Bestimmung der aktiven aeroben, heterotrophen mikrobiellen Biomasse in landwirtschaftlich genutzten Böden und in Mineralböden fest.
Dieser Teil von ISO 14240 ist nicht auf die Bestimmung der Wirkung von Chemikalien auf die Biomasse anwendbar.

Qualité du sol - Détermination de la biomasse microbienne du sol - Partie 1 : Méthode par respiration induite par le substrat (ISO 14240-1:1997)

La présente partie de l'ISO 14240 prescrit une méthode pour l'estimation de la biomasse microbienne aérobie hétérotrophe active dans les sols agricoles et minéraux aérés. La détermination des effets des produits chimiques sur la biomasse n'entre pas dans le domaine d'application de la présente partie de l'ISO 14240.

Kakovost tal - Določevanje talne mikrobne biomase - 1. del: Metoda respiracije, inducirane s substratom (ISO 14240-1:1997)

Ta del IS0 14240 določa metodo za ocenjevanje aktivne aerobne, heterotrofne mikrobne biomase v zračenih kmetijskih in mineralnih tleh. Ugotavljanje učinkov kemikalij na biomaso ne spada v obseg uporabe tega dela IS0 14240.

Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0
member bodies). The work of preparing International Standards is normally carried out through IS0 technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard IS0 14240-l was prepared by Technical Committee ISOmC 190, Soil quality, Subcommittee
SC 4, Biological methods.
IS0 14240 consists of the following parts, under the general title Soil quaMy - Determination of soil microbial
biomass:

Introduction
Soil consists of both living and nonliving components which exist in a complex and heterogeneous environment. Soil
microflora is responsible for the degradation of organic matter, stability of aggregates and most nutrient cycling
which occurs in soils. The purpose of determining the microbial biomass of soils is to allow assessment of the
continued maintenance of soil fertility, the potential ability to degrade organic materials, and the effects
