Economic aspects of agroecological assessment of soils (lands) of the Azov-Kuban lowland

The paper discusses the main approaches to assessing the qualitative state of soils. ‘Normal’ and ‘normative’ crop yields are calculated. Comparison of the obtained calculated yields, depending on the properties and composition of soils, with the actual yield is made. It was concluded that the yield decreases when moving from not prone to degraded soils. Using the methods for ‘normal’ and ‘normative’ crop yields, the production value of soils was assessed. The indicator of ‘normative’ yield is analyzed taking into account the value of the agroecological potential. It is concluded that the use of ‘normative’ yield is the most appropriate for assessing the production value of soils in agricultural production, since this method reflects the difference between soils of better and worse quality. For comparison, the data on determining the assessment of the qualitative state of soils according to the bonitet score of agricultural crops are given. Studies have shown that due to the manifestation of degradation processes in soils, the production value of soils is currently decreasing. It was concluded that the dynamics of the structure of the soil cover, composition and properties of soils led to the lost profit due to the short productsreceived
