Водопроницаемость мерзлых черноземов обыкновенных и светло-каштановых почв нижнего Поволжья под влиянием карбоната калия

Водопроницаемость мерзлых черноземов обыкновенных и светло-каштановых почв нижнего Поволжья под влиянием карбоната калия

Abstract

Following results were obtained: soil permeability is directly related to the mechanical composition, soil pore size, moisture content and temperature of the frozen soil, the presence of «barrier layer». Water infiltration into frozen soil is significantly lower than in the thawed one. In all test samples linear dependence of defrost time and the percentage of thawed soil from the amount potassium carbonate was defined. The dependence of the amount of thawing time on frozen soil volume is defined. The optimum pH value of the solution of potassium carbonate, permissible to use on light-brown soils and ordinary chernozems is revealed.

Были получены следующие результаты: водопроницаемость почв напрямую связана с механическим составом, размерами почвенных пор, влажностью и температурой мерзлой почвы, наличием «запирающего слоя». Инфильтрация воды в мерзлую почву значительно ниже, чем в талую. Во всех опытных образцах определена линейная зависимость времени оттаивания и процента оттаявшей почвы от количества карбоната калия. Установлена зависимость времени оттаивания от объема мерзлой почвы. Выявлен оптимальный показатель pH раствора карбоната калия, допустимый в использовании на светло-каштановых почвах и черноземах обыкновенных.
