title: Maximum humus horizon thickness as a criterion for identifying the soil standards of the plain Сrimea
abstract: When identifying the main categories of soil in the structure of the regional Red Book of soils, it is necessary to focus on typical soils formed taking into account the zonal soil-ecological conditions of the territory. The criterion for the extraction of soil standards can be the initial, pre-agrogenic thickness of the humus horizon, which fully realizes the soil-forming potential of natural factors of climax full-profile soils. But the search for such sites is associated with a number of meth
