Efficiency of using agricultural land in the context of natural and economic zones of the Krasnodar Kari in order to involve them into circulation

. The efficiency of using agricultural land in the context of natural and economic zones of the Krasnodar Krai in order to involve them into circulation is studied in this paper. It is analyzed that the productive properties of the land directly depend on the fertility of the soil, which is characterized by soil types, humus reserves, mechanical composition and other indicators. Soil fertility was assessed, the indicator of which is the bonitet score.


Introduction
The Krasnodar Krai is famous for its fertile lands, but it must be remembered that the lands of the municipalities of the Kraisomehow differ in quality. Consequently, the efficiency of agricultural production in individual regions will differ from each other.
In order to determine the efficiency of the use of agricultural land by municipalities of the Krasnodar Krai, taking into account the productive properties of land in the context of natural and economic zones, we will find, for a start, the average soil score for each municipal formation in the context of agricultural zones. There are six such zones in the region: Northern, Central, Western, Anapo-Taman, South-Piedmont, and Black Sea.

Materials and methods
From the materials of the assessment of the lands of the Krasnodar Krai (initial indicators of soil fertility) in 1990, we write down the soil scores of dry arableland and irrigated arableland in Table 1 by municipalities and group them by zones [1]. From table 1, it can be noted that the soil score of dry and irrigated arable land differs among themselves depending on the municipality, with the exception of Bryukhovetsky, Vyselkovsky, Dinsky, Kavkazsky, Korenovsky, which are located in the Central zone, and Starominsky district, as well as the city of Gelendzhik. In these municipalities, the soil score of dry and irrigated arable land is the same. In such areas as: Beloglinsky, Yeysky, Kushchevsvsky and Otradnensky, there is no irrigated arable land, these areas are included in the Northern zone of the region.
In the report on the availability and distribution of lands in the Krasnodar Krai, we took information on the area of all arable land and the area of irrigatedarable land. The area of dryarable landwas found as the difference between the area of all arable land and the area of irrigatedarable land [2].
All data on municipalities and areas by zones are shown in Table 2. From the information given in Tables 1 and 2, we find the average bonitet of arable land in the municipalities of the region in the context of zones according to formula 1: where‫ܤ‬ ௗ௬dry arable land soil score; S ୢ௬dry arable land area, ha; ‫ܤ‬soil score of irrigated arable land; S ୧irrigatedarable land area, ha; S ୲୭୲ୟ୪total arable land area, ha. Let's calculate the average bonitet scores of arable land for all municipalities of the Krasnodar Krai according to formula 1 and group them by zones. Let'swrite the obtained results in Table 3.

Conclusions
The above data in the tables clearly show that the assessment scores for the municipalities of the region are quite high. Therefore, this allows concluding about the fertility of the land.
In our opinion, it is imperative to take into account the fertility of agricultural land in the Krasnodar Krai, since this will give an impetus to the functioning and development of the agricultural land market and, accordingly, the country's economy as a whole.
