Aim. To consider soil continuality and discreteness as features of heterogeneity manifestation in a soil cover, important for construction of agriculture systems. Methods. Geostatistical research of soil spatial heterogeneity, revealing the contours of a fi eld with various parameters of fertility. Results. The use of principles of precise agriculture and inspection of indicative properties of fi eld soils using a regular grid allowed to divide a fi eld into contours with three levels of fertility: the fi rst one is characterized by optimal or close to optimum properties which allows refusing from (or reducing substantially) tillage, introduction of fertilizers or chemical ameliorates; the second one has average parameters of fertility corresponding to zonal soils and demands the application of zonal technologies; the third one (with the worst parameters of fertility) presupposes regular use of the improved technologies. Conclusions. The introduction of precise agriculture will allow replacing a traditional zonal system with thenew which is soil-protecting and resource-saving one.

This year is the centenary of the death of the Russian publicist and religious thinker V.V. Rozanov. And this year also follows the year of the 110th anniversary of the great Soviet writer, philosopher and futurist I.A. Efremov. The first figure ended the era, gathering and absorbing all the rushing about, as well as political and spiritual conflicts of the Russian intelligentsia in the time of the outgoing monarchy. The latter was born at the beginning of the new era and proclaimed the images of the great future. It’s an interesting question whether they, like the images of their corresponding eras, differ immensely, and we could say that they are split and unrelated. Or if the images of the later epoch are the continuation of the former ones, overcoming the deadlocks of the old era and solving its conflicts. Did the intellectuals of the Soviet era discard the problems of the tsarist intellectuals or, on the contrary, did they manage to offer advanced answers? The philosophy of V.V. Rozanov, so original and not fully explored to this day, could not but be reflected in the works of his successors and heirs. Revealing similar trends of philosophical thought in the legacy of the Soviet period, the author of the article comes to the conclusion that a number of analogous issues were investigated also by I. A. Efremov.
