Soil quality - Biological methods - Determination of nitrogen mineralization and nitrification in soils and the influence of chemicals on these processes (ISO 14238:2012)

This International Standard specifies laboratory procedures for measuring the mineralization and nitrification of nitrogen by the soil microbiota.
For investigations on the evaluation of soil quality or on effects of contamination, a procedure is given to measure the rates and extent of N-mineralization in soil or soils of known or unknown quality.
For investigation of the potential toxicity of chemicals to N-mineralization in soils, a simple procedure is given which allows the impact of single chemicals to be assessed and provides a basis for comparison of the toxicities of different chemicals.

Bodenbeschaffenheit - Biologische Verfahren - Bestimmung der Stickstoffmineralisierung und -nitrifizierung in Böden und der Einflüsse von Chemikalien auf diese Prozesse (ISO 14238:2012)

Diese Internationale Norm legt Laborverfahren für die Messung der Mineralisierung und Nitrifizierung von Stickstoff durch Bodenmikroorganismen fest.
Für Untersuchungen zur Beurteilung der Bodenbeschaffenheit und zu Wirkungen von Verunreinigungen wird ein Verfahren angegeben, das den Grad und den Umfang der N-Mineralisierung in Böden bekannter oder unbekannter Qualität misst.
Für die Untersuchung der potentiellen Toxizität von Chemikalien auf die N-Mineralisierung in Böden ist ein einfaches Verfahren angegeben, das die Abschätzung der Wirkung einzelner Chemikalien ermöglicht und eine Grundlage für den Vergleich der Toxizitäten unterschiedlicher Chemikalien darstellt.

Qualité du sol - Méthodes biologiques - Détermination de la minéralisation de l'azote et de la nitrification dans les sols, et de l'influence des produits chimiques sur ces processus (ISO 14238:2012)

L'ISO 14238:2012 spécifie des modes opératoires de laboratoire destinés à mesurer la minéralisation de l'azote et la nitrification par la flore microbienne du sol.
Un mode opératoire est donné pour mesurer les taux et l'importance de la minéralisation de l'azote dans le ou les sol(s) de qualité connue ou inconnue, dans le cadre des recherches relatives à l'évaluation de la qualité du sol ou aux effets de la contamination.
Un mode opératoire simple est donné pour permettre l'évaluation de l'effet de produits chimiques uniques et fournit une base de comparaison des toxicités de différents produits chimiques, en ce qui concerne la recherche de la toxicité éventuelle des produits chimiques pour la minéralisation de l'azote dans les sols.
