CHARACTERISTICS OF GRANULOMETRIC AND AGGREGATE SOILCOMPOSITION OF KUZNETSK ALATAU CHERNEVAYA TAIGA NORTHERNAREA USING THE PARAMETERS OF PROBABILITY FUNCTIONS

Granulometric structure is the major soil physical characteristic and one of thecharacteristics of its dispersion. The main requirement to analyse it is the uniformity oftechniques and research parameters of granulometric structure of different soils and theuniformity of ways of data presentation. Now it is widespread to present the results of thegranulometric analysis in the form of percentage of fractions of particles of various sizewith allocation of borders of these fractions in strict conformity with classification requirementsof particular branch of science or fixed national standards. It involves the incomparabilityof granulometric analysis data obtained by researchers from differentcountries and even certain organisations. It is possible to use mathematical and statisticalmethods of representation to solve the problem of unification of obtained results ingranulometric analysis. Besides these methods can expand essentially information capabilityof granulometric analysis results approximation.The macrostructure analysis using the method of bolting, the sieves coming in variouscell diameter with application of sifting cars allows to provide high standardizationof the obtained results. Digital technologies of the dissemination process control give achance for exact repetition of measurements, what becomes the basis for the comparabilityof results worldwide. According to the results of bolting, structural condition of soilsis estimated, in particular the structure with agronomic value is characterised. Whilecarrying out mass analyses the description of bolting analysis data with the least quantityof parameters is needed to make it easier to compare and structure the results. In thiscase the calculation of factors SGD and SVD is highly useful. Their interpretation is extremelysimple: the higher these factors are, the greater large fractions are expressed inthe structure and vice versa. In the studied soils almost uniform distribution of SGD andSVD with visible regularity to integration of the structure with depth was observed.The knowledge of indicators F5, a, n, k, gives full view of granulometric structureand essentially expands possibilities of granulometric analysis with the help of laser diffractionmethod and interpretation of its results. Combinations of these characteristicvalues allow to identify the object unequivocally; more capacious data file obtainedwhile working with a diffractometer allows to calculate, if necessary, the maintenance offraction of any interval according to the diameter of particles, what gives a chance to useany existing classification irrespective of the accepted fraction borders as well as tomake balance calculations.
