Abstract:
The article deals with the issues of the management of soil fertility based on the application of two methodological approaches
to arable land normative monetary evaluation (NME). These researches have been conducted on the results of economic
activity of the Poltava region agrarian enterprises of Ukraine. The differences between the two methodological approaches to
the calculation of the NME of arable land in the Poltava region are shown. These approaches, namely, on cereals and on five
agricultural crops, presuppose the calculation of the NME of arable land on the basis of capitalized rent income. The
approaches are similar to the Ricardian model of land pricing, which is being widely used with its various modifications in
different countries of the world. Our own methodology for analyzing the approaches to the NME of arable land, based on the
developed stochastic harmonic models (SHM), is represented in the article.
The application of the two methodological approaches to the calculation of the NME of arable land in the Poltava region of
Ukraine, which presupposes its consideration on the data concerning cereals and five agricultural crops, revealed essential
differences between them in the course of the conducted economic-mathematical analysis. It has been found that the methodological
approach on cereals has a lower level of the explanatory attribute variation (of humus content in soils) compared to five agricultural
crops. That finally leads to the essential difference in the optimum values of the arable land NME at increasing humus content in soils.
Thus, the optimum value of the arable land NME within the second methodological approach is twice as much as within the first one.
The measures to improve the arable land NME, based on the data of the Poltava region and can be successfully used all over Ukraine, as well as in many countries of the world. The advantages of applying the methodological approach based on five
agricultural crops were studied and grounded in the current research. This approach proves the dependence on arable land
NME on the humus content and enables higher objectivity for effective and rational management of soil fertility.
