Soil improvers and growing media - Methods for sampling and sample preparation
This document specifies references to methods for sampling of soil improvers and growing media and sample preparation of soil improvers and growing media for subsequent determination of quality and quantity.
This document is applicable to the fertilizing product blends where a blend is a mix of two or more fertilising products belonging to the categories of fertilizers, liming material, soil improvers, growing media, inhibitors and plant biostimulants, and where soil improvers and/or growing media are the components with the highest percentage in the blend by mass or volume, or in the case of products in liquid form by dry mass. If the soil improvers and/or growing media are not the components with the highest percentage in the blend, the European Standard relevant to the component with the highest percentage in the blend applies. In case a blend is composed of fertilising products mixed in equal quantities, the user of the standard decides which standard to apply.
NOTE A soil improver or a growing medium consists of a single bulky (volume-building) component or a mix of bulky (volume-building) components (for example peat, wood fibres, coconut coir, compost, expanded perlite).
Bodenverbesserungsmittel und Kultursubstrate - Probenahme
In diesem Dokument sind Verweisungen auf Verfahren der Probenahme von Bodenverbesserungsmitteln und Kultursubstraten sowie der Probenvorbereitung von Bodenverbesserungsmitteln und Kultursubstraten für die anschließende Bestimmung von Qualität und Menge aufgeführt.
Dieses Dokument ist für Düngeproduktmischungen anwendbar, wenn die Mischung aus mindestens zwei Düngemittelprodukten der folgenden Kategorien besteht: Düngemittel, Kalkdünger, Bodenverbesserungsmittel, Kultursubstrate, Hemmstoffe und Pflanzen-Biostimulanzien, sowie wenn Bodenverbesserungsmittel und/oder Kultursubstrate die Bestandteile mit dem höchsten Massen- oder Volumenanteil in der Mischung oder, im Fall von Produkten in flüssiger Form, dem höchsten Trockenmasseanteil sind. Wenn die Bodenverbesserungsmittel und/oder Kultursubstrate nicht den höchsten prozentualen Anteil in der Mischung ausmachen, ist die für den Bestandteil mit dem höchsten prozentualen Anteil in der Mischung geltende Europäische Norm anwendbar. Falls eine Mischung aus in gleichen Mengen gemischten Düngeprodukten besteht, entscheidet der Anwender, welche Norm angewendet wird.
ANMERKUNG Ein Bodenverbesserungsmittel oder Kultursubstrat besteht aus einem einzigen schüttfähigen (Volumen aufbauenden) Bestandteil oder aus einem Gemisch schüttfähiger (Volumen aufbauender) Bestandteile (z. B. Torf, Holzfasern, Kokosfasern, Kompost, Blähperlit).
Amendements organiques et supports de culture - Echantillonnage
Le présent document spécifie les références aux méthodes d’échantillonnage et de préparation de l’échantillon des amendements du sol et des supports de culture en vue d’une détermination ultérieure de la qualité et de la quantité.
Le présent document est applicable aux mélanges de produits fertilisants constitués d’au moins deux produits fertilisants appartenant aux catégories suivantes : engrais, amendements minéraux basiques, amendements du sol, supports de culture, inhibiteurs et biostimulants des végétaux et, dans lesquels les amendements du sol et/ou les supports de culture sont les composants qui représentent le pourcentage le plus élevé du mélange en masse ou en volume, ou dans le cas d’un liquide, en masse sèche. Si les amendements du sol et/ou les supports de culture ne sont pas les composants qui représentent le pourcentage le plus élevé du mélange, la Norme européenne applicable au composant ayant le pourcentage le plus élevé dans le mélange s’applique. Dans le cas où le mélange de produits fertilisants est constitué de composants en quantités égales, l’utilisateur décide quelle norme appliquer.
NOTE Un amendement du sol ou un support de culture se compose d’un seul composant volumineux (augmentant le volume) ou d’un mélange de composants volumineux (augmentant le volume) (par exemple, la tourbe, les fibres de bois, la fibre de coco, le compost, la perlite expansée).
