THE OPTIMAL STRATEGY OF THE SOIL SAMPLING ON THE BASIS OF THE TECHNOSEMS ELECTRICAL CONDUCTIVITY DATA

The possibility of an estimation of spatial variability of edaphic properties of industrial lands have been shown by Kriging of the 20 points which position have been established according algorithm of spatial response surface sampling (SRSS) on the basis of soil electrical conductivity data in 160 sampling points which have been situated on a regular grid. are established The most informatively important edaphic indicators have been established by means of the multidimensional factor analysis: concentration of an ion of calcium, рН a water extract, the sum of ions potassium and sodium in a water extract, the humus content. The offered scheme of sampling allows receiving integrated statistical estimations of parameters of distribution of the given indicators which samples at small volume authentically do not differ from the estimations received at great volume of the collected material. The organization of gathering of tests on algorithm SRSS by data soil electrical conductivity allows to receive satisfactory spatial model of variability of properties which correlate with electrical conductivity. In our research it is concentration of monovalent ions (Ka+ + Na+) in a soil extract and humus contamination.
