N. Sokolovsky» popup.description2  The object of research - reference materials of the composition (agrochemical parameters) of dark chestnut slightly saline soil, chernozem podzolic and gray forest soil. The purpose of research is to develop the methodology and improve methods of production reference materials of composition (agrochemical indicators) of soils, to make industry reference materials of composition (agrochemical indicators) of dark chestnut slightly saline soil, chernozem podzolic and gray forest soil. Research methods - methods of theoretical analysis, systematic approach and comparative analysis of methods of preparation and certification of reference materials, expert evaluation of published information, laboratory-analytical experiments, statistical processing methods data. Theoretical results - the methodological and methodological basis for the development of reference materials of soil composition (agrochemical parameters) has been improved. From a metrological point of view, the characteristic properties of soil as a unique natural system, which is characterized by fertility, are analyzed, which distinguish the reference material of soil composition from the materials of reference materials of other types of materials. The available information on the methodology and methods of development and production of reference materials of matrix materials is summarized. A method for studying the identity of the chemical composition of industry reference materials, based on periodic measurement of pH buffering, has been developed. Practical results - Industry reference materials of the composition (agrochemical parameters) of dark chestnut slightly saline soil, chernozem podzolic and gray forest soil with packages of technical documentation (type description and passport) were made. Industry reference materials were introduced in the testing laboratory of the Druzhba-Nova Agricultural Limited Liability Company in 2020. Field of application - analytical chemistry.
