Sokolovski" popup.description2 The object of investigation - a reference material of typical clay-loam chernozem for organization. The purpose of the work - the creation of a reference material of organizationof typical chernozem with a package of technical documentation to determine the stability characteristics of the reference material. Investigation techniques - laboratory and analytical experiments, statistical methods of data processing, expert assessment of published information. Results - compiled information and analytical background for the development of reference materials for organization. Reference material for organization was developed. Soil material was collected, it was dried, homogenized and packed in paper bags weighing 1 kg. Certified values are determined and certified values of error (including errors from the inhomogeneity) of agrochemical indices: mobile phosphorus compounds (Chirikov method), mobile potassium compounds (Chirikov method), pH, salt extraction, hydrolytic acidity, organic matter, available (labile) organic matter, the group composition of humus, nitrogen of nitrates, the salt composition of the aqueous extract, exchangeable calcium, exchangeable magnesium, exchangeable potassium. The projects of the passport, the label, describing the type of reference material, certificate for the reference material, instructions for use, which are part of a package of technical documentation for the development of a reference material for organization. Fields of application are agriculture and analytical laboratories of ISSAR and its net.
