Abstract
The paper highlights the data on agroecological assessment and land typing on the example of farm “Kremlin” located in Kochenevo district of Novosibirsk region. This method aims at solving two problems. The first problem deals with typing and it is carried out on the basis of the associated analysis of triunity which implies environmental conditions of the area, agricultural crops, and agricultural technology; the second problem deals with topology: the boundaries of spatial plots of land types coincide with the boundaries of geochemical positions, which are characterized by external features of the relief elements and soil contours. Agroecological land typing includes grouping of lands and their mapping. The criterion for land grouping is seen in similarity of factors that restrict certain crop yields and application of certain technological methods. The authors suggest to use morphometric parameters of the soil mantle for identifying land types: average number of permeable intervals in the section of soil areal, contrast ratio, complexity coefficient and soil cover heterogeneity coefficient. A quantitative parameter of agroecological conditions similarity within the plot is lower contrast ratio. The efficiency of this method is confirmed by economic parameters. Digital mapping and quantitative analysis of morphometric soil mantle parameters was carried out by means of MapInfo Professional software.
