ČSN P CEN/TS 17758 This document specifies a method for the determination of the chloride content in organic fertilizers, organo-mineral fertilizers, inorganic fertilizers and liming materials by potentiometric titration.

Obsah

ČSN P CEN/TS 17759 This document specifies a method for the determination of pH of a solution of ammonium nitrate fertilizer of high nitrogen content.

Obsah

ČSN P CEN/TS 17760 This document specifies a method for the determination of particle size of ammonium nitrate fertilizers of high nitrogen content.

Obsah

ČSN P CEN/TS 17761 This document specifies a method for the determination of the chloride content in ammonium nitrate fertilizers of high nitrogen content.

Obsah

ČSN P CEN/TS 17762 This document specifies a method for the determination of the copper content in ammonium nitrate fertilizers of high nitrogen content.

Obsah

ČSN P CEN/TS 17766 This document specifies a method for the extraction by water for the subsequent determination of elements. The extracts are suitable for analysis using CEN/TS 17774. NOTE - Alternatively, inductively coupled plasma mass spectrometry (ICP-MS) can be used for the measurement if the user proves that the method gives the same results. The method is applicable to organic and organo-mineral fertilizers.

Obsah

ČSN P CEN/TS 17767 This document specifies the procedure for the extraction of phosphorus in 2 % formic acid (20 g/l), representing the amount of soft natural phosphates. The method is applicable to organo-mineral fertilizers.

Obsah

ČSN P CEN/TS 17772 This document specifies references to the methods for the: - Determination of the total organic carbon content; - Determination of the dry matter content. This document is applicable to fertilizing products, which are classified as PFC 1(A) and PFC 1(B) or the PFC 1(A) and PFC 1(B) component in PFC 7 of Regulation (EU) 2019/1009.

Obsah

ČSN P CEN/TS 17773 This document is applicable to fertilizing products, which are classified as PFC 1(A) and PFC 1(B) or the PFC 1(A) and PFC 1(B) component in PFC 7 of Regulation (EU) 2019/1009. However, the present method was not validated for blends. This document specifies the procedure for the determination and calculation of the dry matter fraction of organic and organo-mineral fertilizers for which the results of the performed analysis are calculated to the dry matter basis.

Obsah

ČSN P CEN/TS 17779 This document specifies a method for the extraction of phosphorus soluble in neutral ammonium citrate. The method is applicable to organo-mineral fertilizers.

Obsah

ČSN P CEN/TS 17785 This document specifies references to the methods for the determination of chelating and complexing agents in organo-mineral fertilizers. The document specifies references to the methods and requirements for organo-mineral fertilizers in accordance with PFC 1 (B) as specified in the Regulation (EU) 2019/1009. Organo-mineral materials for this purpose are organic fertilizers containing micronutrient chelates or complexes and/or mixtures of them, in powder or granular form, aqueous or suspension preparations.
