title: Maximum Humus Horizon Thickness as a Criterion for Identifying Standard Soils in the Crimean Plain
abstract: Abstract—The identification of the main soil categories in the structure of the regional Red Book should focus on typical soils that were formed taking into account the zonal soil-ecological conditions of the territory. The initial, preagrogenic thickness of the humus horizon that fully implements the soil-forming potential of natural factors of full-profile climax soils can serve as a criterion for identifying standard soils.
