Plant biostimulants - Determination of dry matter

This document specifies the procedure for the determination of dry residue and calculation of the dry matter fraction of plant biostimulants for which the results of performed analysis are to be calculated to the dry matter basis.
This document is applicable to the blends of fertilizing products where a blend is a mix of at least two of the following component EU fertilizing products categories: Fertilizers, Liming Materials, Soil Improvers, Growing Media, Inhibitors, Plant Biostimulants, and where the following category Plant Biostimulants is the highest percentage in the blend by mass or volume, or in the case of liquid form by dry mass. If Plant Biostimulants is not the highest percentage in the blend, the European Standard for the highest percentage of the blend applies. In case a blend of fertilizing products is composed of components in equal quantity or in case the component EU fertilising products used for the blend have identical formulations, the user decides which standard to apply.

Pflanzen-Biostimulanzien - Bestimmung der Trockenmasse

Dieses Dokument legt das Verfahren zur Bestimmung des Trockenrückstands und Berechnung des Trockenmassenanteils von Pflanzen-Biostimulanzien fest, für die die Ergebnisse der durchgeführten Analyse bezogen auf die Trockenmasse zu berechnen sind.
Dieses Dokument ist für die Mischungen von Düngeprodukten anwendbar, in denen eine Mischung aus mindestens zwei der folgenden Kategorien von Komponenten-EU Düngeprodukten besteht: Düngemittel, Kalkdünger, Bodenverbesserungsmittel, Kultursubstrate, Hemmstoffe, Pflanzen-Biostimulanzien und wenn die folgende Kategorie Pflanzen-Biostimulanzien prozentual den höchsten Massen- oder Volumenanteil in der Mischung bzw., bei flüssiger Form, den höchsten Trockenmasseanteil aufweist. Wenn Pflanzen-Biostimulanzien nicht den höchsten prozentualen Anteil in der Mischung ausmachen, ist die für den höchsten prozentualen Anteil geltende Europäische Norm anwendbar. Falls eine Düngemittelmischung aus Komponenten gleicher Menge besteht oder falls die für die Mischung verwendeten Komponenten-EU Düngeprodukte identische Formulierungen haben, entscheidet der Anwender, welche Norm angewendet wird.

Biostimulants des végétaux - Détermination de la matière sèche

Le présent document spécifie le mode opératoire pour la détermination de résidu sec et le calcul de la fraction de matière sèche de biostimulants des végétaux pour lesquels les résultats des analyses menées doivent être calculés sur la base de la matière sèche.
Le présent document est applicable aux mélanges de fertilisants constitués d’au moins deux composants appartenant aux catégories de fertilisants UE suivantes : engrais, amendements minéraux basiques, amendements du sol, supports de culture, inhibiteurs, biostimulants des végétaux et, dans lesquels la catégorie Biostimulants des végétaux représente le pourcentage le plus élevé du mélange en masse ou en volume, ou dans le cas d’un liquide, en masse sèche. Si les biostimulants des végétaux ne représentent pas le pourcentage le plus élevé du mélange, la Norme européenne relative au composant représentant le pourcentage le plus élevé du mélange s’applique. Dans le cas où un mélange de fertilisants contient des composants en quantité égale ou dans le cas où les composants des fertilisants UE utilisés pour le mélange ont des formulations identiques, l’utilisateur décide quelle norme appliquer.
