Inorganic potassium fertiliser - as K2O (nutrient supply from NPK (26-15-15) fertiliser)

The activity generating the emissions is nutrient supply from NPK (26-15-15) fertiliser. The reference product is inorganic potassium fertiliser, as K2O. Inorganic potassium fertiliser, as K2O describes a substance which is supplying the nutrient of Potassium to plants. The product represents an equivalent form of Potassium that is present in the fertiliser and is expressed as a mass of potassium oxide (K2O). The term "inorganic" refers to the source of nutrient being produced from chemical or artificial materials. Modelling this substance in a solution requires the user to add the solvent of their choice in their models. Based on EU regulations (REGULATION (EU) 2019/1009), when this substance is used as fertiliser, the N-P-K can vary depending on the fertiliser. The reference product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary ordinary transforming activity.
