24、177:2011EN ISO 25177:2011 (E) BSI 2011vForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member bod

25、y 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. ISO collaborates closely with the International Electrote

26、chnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by

27、 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. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rig

28、hts. ISO shall not be held responsible for identifying any or all such patent rights. ISO 25177 was prepared by Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 1, Evaluation of criteria, terminology and codification. This first edition of ISO 25177 cancels and replaces ISO 11259:1998,

29、which has been technically revised. BS EN ISO 25177:2011EN ISO 25177:2011 (E) BSI 2011vi Introduction Traditionally, descriptions of soils and their environment were carried out as parts of soil survey and soil inventories, the purpose of which was to describe the pedogenetic context of the soil and

30、 assess applied aspects, principally agronomic potentials. Today, many soil observations are made as part of much wider environmental studies, and include analysis for objectives such as the following: the identification of human influences on the soils, particular attention being paid to the negati

31、ve effects of these influences (for example, pollution and physical deterioration); land protection within the context of “sustainable” agriculture; the prediction of the fate of contaminants introduced into the soil; the assessment of the consequences resulting from changes in the use of the soil;

32、setting up monitoring programmes for specific purposes (observation of changes of soil properties in time); the development of spatial data bases (used in the context of GIS) aimed at facilitating the geographical representation of these; many other uses. Therefore, this International Standard is ba

33、sed on aspects of the traditional approach to soil description for example, the Guidelines for soil description FAO ROME (2006). The descriptions of soils and sites alone are not sufficient. Field and laboratory measurements, whether physical, chemical or biological, must accompany this description.

34、 Care must be taken in the specification of sites and in the methods of sampling and the number of samples. It is therefore imperative that this International Standard be considered in the context of other International Standards developed within the framework of ISO/TC 190, Soil quality. BS EN ISO

35、25177:2011EN ISO 25177:2011 (E) BSI 2011INTERNATIONAL STANDARD1Soil quality Field soil description 1 Scope This International Standard is a guide for describing the soil and its environmental context at a given site. Sites can be natural, near-natural, urban or industrial. It is important to realize

36、 that a number of soil samples can be taken at a site to support the soil description. The information provided by the descriptions in this International Standard provides the context for the presentation of results from analyses undertaken on soil samples. NOTE 1 It might not be possible or necessa

37、ry to record data under all the headings listed in these descriptions. NOTE 2 Overall guidance for presentation of information from soil surveys is given in ISO 15903. 2 Normative references The following referenced documents are indispensable for the application of this document.
