Fertilizers - Determination of calcium and formate in calcium foliar fertilizers
N EN 15909
Annotation
This European Standard specifies a method for the determination of the content of calcium and formate in calcium foliar fertilizers in the presence of calcium chloride. This is determined and calculated by individual analytical determination of the following components:
— Calcium (Ca2+),
— Chloride (Cl-),
— Formate (HCOO-).
The method is applicable to calcium foliar fertilizers with a calcium content of approximately 30 %.

Удобрения - Определение кальция и формиата в кальции лиственные удобрения
Этот европейский стандарт определяет метод для определения содержания кальция и формиата в кальции лиственные удобрения в присутствии хлорида кальция. Это определяется и вычисляется отдельным аналитическим определением следующих компонентов:
— Кальций (Ca2 +),
— Хлорид (Статья-),
