Soils. Method for determination of exchangeable sodium
Почвы. Метод определения обменного натрия
Status: Effective. The limitation of effectiveness has been lifted: Resolution of the State Standard No. 1994 of 12/18/91
The standard applies to soils, overburden and host rocks and establishes a method for determining the content of exchangeable sodium in soil, agrochemical, land reclamation surveys, monitoring soil condition, as well as in other survey and research works. The standard does not apply to the analysis of samples of organic horizons.
Стандарт распространяется на почвы, вскрышные и вмещающие породы и устанавливает метод определения содержания обменного натрия при почвенном, агрохимическом, мелиоративном обследовании угодий, контроле за состоянием почв, а также при проведении других изыскательских и исследовательских работ. Стандарт не распространяется на анализ проб органических горизонтов.
