Abstract

As object the field by the area of 40 hectares in Forest-steppe of the Kharkiv area on which three types of soil are allocated - chernozem typical poorly eroded, chernozem podsolic and dark grey podsolic. The regular network from 45 elementary plots on a field have put. On everyone them the contents of physical clay and total humus (in the subsequent models it there were base parameters), and also equilibrium bulk of density, penetration resistance, blocks (functional parameters) and the crop are considered. Statistical parameters and geostatistics are calculated. Results of processing of the spatial information were those. Factors of pair and plural correlation between base and functional parameters - within the limits of 0,5-0,8, factors of a variation - low for the content of humus, physical clay and bulk of density, moderately high for penetration resistance and very high - for block. The variogam - mainly spherical type, the nagget-effect was insignificant, and the radius of correlation has made about 240-260 m. Though variability of base parameters was moderate, and functional raised, presence of autocorrelation function, that is its authentic deviation from zero, proves existence of spatial heterogeneity on the investigated field. About same obvious peaks on curves of spectral density of a dispersion testify. It means, that connections between base and functional parameters were encouraging enough, their spatial structures in the investigated field relatives, and search of borders between allotments with various fertility, it has appeared quite proved and successful.  The final stage of processing consisted in construction of 2-D-diagrams on experimental data (with use of software Surfer), and then the same diagrams of blocks, bulk of density and of penetration resistance (as indicators of preseeding precise tillage) on settlement pedotransfer models. Instead of difficult procedure of an establishment of spatial heterogeneity of a field and revealing on it of contours with various physical properties it is offered to take advantage of pedotransfer models. As the basis for this purpose close values of thresholds of a dispersion and radiuses of correlation, authentic correlation connections between soil base and functional parameters have served uniformity spherical variogrammes. For a choice of intensity of preseeding operations normative parameters for display physical properties of a sowing layer are proved. Revealed on the basis of settlement models and natural researches on a field agritechnology contours for differentiation of intensity of preseeding tillage have appeared similar enough on a configuration and the area. Thus, in article the basic opportunity of allocation on a field agritechnology groups for carrying out of various ways of machining, using for this purpose pedotransfer models is shown. Pedotransfer modelling can become actual only on condition that other, more simple and effective ways of measurement of base parameters will be found, it is desirable in modes in situ and on-line. Pedotransfer models are perspective in precise agriculture under condition of development of remote methods of definition of base parameters.
