N. Sokolovsky» popup.description2 The object of research is soils of various types of soil formation. The purpose of the research is to develop the scientific and methodological aspects of determining the granulometric composition in soils of various types of soil formation by the laser diffraction method. Research methods are field, analytical, theoretical, general scientific, statistical. Theoretical results – the methodical approach has been improved, an algorithm and a method of soil sample preparation before measurement on a laser particle analyzer have been developed, taking into account the standards of Ukraine; the possibility of using the laser diffraction method for determining the granulometric composition of soil samples taken at the sites of hostilities has been proven; it was established that when measuring the particles of soil samples on a laser analyzer, it is necessary to take into account the place of sample selection, namely the soil-climatic zone (subzone) according to the conditions of moisture, because the optical indicator - the refractive index - is different for different types of soils. Regression equations for each fraction are proposed for converting data from the laser diffraction method into data according to DSTU 4730:2007. Practical results – the scientific and methodological aspects of determining the granulometric composition in soils of various types of soil formation using the laser diffraction method have been developed, which will contribute to the development of analytical support for determining the condition of the soils of Ukraine. The novelty consists in determining the granulometric composition in the soils of Ukraine based on the analysis of the light-scattering properties of particles. Effectiveness of implementation – reduction of the cost and time for determining the granulometric composition of the soil while improving the reproducibility of the results. The sphere (field of use) is agriculture. Product Description popup.authors Vynokurova Nadiya V Lazebna Maryna Yevheniivna Nevoit Olena I.
