Fertilizers - Extraction of water soluble micro-nutrients in fertilizers and removal of organic compounds from fertilizer extracts

This European Standard specifies a method for the extraction of water soluble forms of boron, cobalt, copper, iron, manganese, molybdenum and zinc from mineral fertilizers containing one or more micro-nutrients and the procedure for removal of organic compounds from the water extracts.
The extracts can be analysed according to EN 16963, EN 16965, prEN 17041, prEN 17042, prEN 17043 and CEN/TS 17060.

Düngemittel - Extraktion wasserlöslicher Spurennährstoffe aus Düngemitteln und Beseitigung organischer Verbindungen aus Düngemittelextrakten

Diese Europäische Norm legt ein Verfahren zur Extraktion wasserlöslicher Formen von Bor, Cobalt, Kupfer, Eisen, Mangan, Molybdän und Zink aus mineralischen Düngemitteln, die einen oder mehrere Spurennährstoffe enthalten, und das Verfahren zur Beseitigung organischer Verbindungen aus den Wasser¬extrakten fest.
Die Extrakte können nach EN 16963, EN 16965, prEN 17041, prEN 17042, prEN 17043 und nach CEN/TS 17060 analysiert werden.

Engrais - Extraction des oligo-éléments soluble dans l'eau des engrais et élimination des composés organiques dans les extraits d'engrais

La présente norme européenne spécifie la méthode pour l’extraction des formes solubles dans l’eau du bore, du cobalt, du cuivre, du fer, du manganèse, du molybdène et du zinc à partir d’engrais minéraux contenant un ou plusieurs oligo-éléments et le mode opératoire d’élimination des composés organiques dans les extraits aqueux.
Les extraits peuvent être analysés conformément aux EN 16963, EN 16965, prEN 17041, prEN 17042, prEN 17043 et CEN/TS 17060.

Gnojila - Ekstrakcija v vodi topnih mikrohranil iz gnojil in odstranitev organskih spojin iz ekstraktov gnojil

Ta evropski standard določa postopek za ekstrakcijo v vodi topnih oblik bora, kobalta, bakra, železa, mangana, molibdena in cinka iz mineralnih gnojil, ki vsebujejo eno ali več mikrohranil, ter postopek za odstranjevanje organskih zmesi iz ekstraktov vode.
Ekstrakti se lahko analizirajo skladno s standardi WI 00260173, prEN 16963, prEN 16965, WI 00260179, WI 00260180 in WI 00260182.

It is applied only in some cases for determination of boron and molybdenum by spectrophotometric methods, determination of boron by acidimetric titration and gravimetric determination of molybdenum. The method for removal of organic compounds is a part of this standard. WARNING — Persons using this European Standard should be familiar with normal laboratory practice.
