Abstract
The author’s article presents information on the study of the stability of main indicators of fertility (mobile forms of phosphorus and potassium, organic matter) in different types of soil. Experiments were carried out on state reference materials selected in different soil-climatic zones, within 12-30 years since the date of reference material certification. It has been established that different types of soil preserve sufficient stability of the content of mobile forms of phosphorus and potassium, organic matter in reference material provided that reference materials were kept in storage in dry room in removal from the installations that create vibration, with the lack of vapor steams and the relative humidity of the air not higher than 70 %.
The results of the studies of stability of main characteristics of soil fertility (mobile forms of phosphorus and potassium, organic matter) allow us to recommend a guaranteed storage period of reference materials of soils certified for these indicators during 10 years.
