Mullalämmastikku

Mullalämmastikku is a term that is not widely used in Finnish scientific literature. There is no established formal definition for it in the field of soil science, and it does not appear as a standardized concept in major databases or journals. Consequently, its meaning can vary between sources.

In practice, writers who encounter the term may use it informally to refer to nitrogen-related aspects of soil, such as nitrogen content in the soil, or the broader nitrogen cycle, including mineralization, nitrification, immobilization, and plant uptake. Because it is not standardized, there is no agreed method for measuring it or for assigning units.

Due to its ambiguity, Mullalämmastikku should be treated as a colloquial or context-dependent expression rather than a precise scientific term. When discussing soil nitrogen in Finnish, it is preferable to use established terms such as typpikierto (nitrogen cycle), mineralisaatio (mineralization), nitrifikaatio (nitrification), or typpivarastot (nitrogen pools). If encountered in a source, it is advisable to check the author’s definition or seek corroborating references.
