Abstract

This document specifies sampling plans and methods of representative sampling of plant biostimulants to obtain samples for physical, chemical and biological analysis. It is applicable to the sampling of batches of plant biostimulants supplied or ready for supply to third parties, as such, or in smaller batches. 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: Fertilizers/Liming Materials/Soil Improvers/Growing Media/Inhibitors/Plant Biostimulants, and where the following category Plant Biostimulants is the highest % in the blend by mass or volume, or in the case of liquid form by dry mass. If Plant Biostimulants is not the highest % in the blend, the European Standard for the highest % 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 formulations1, the user decides which standard to apply. Note 1 to entry: An example of such a blend is a product with 2 claimed functions consisting of a non-microbial plant biostimulant and an organic fertiliser composed of 1kg/kg of plant biostimulant from seaweed. This document is intended to be used by manufacturers, buyers and competent authorities to obtain samples prior to transport and supply it to a laboratory for testing.
