Certification of reference materials for agricultural analysisFunded under: FP2-BCR 4
To improve product quality in agriculture necessitates investigations at various stages of production, to increase the productivity and to improve the nutritional quality of the plants. It is important to verify the composition of the soil, of the applied fertilisers and products added to the soil. In order to improve the state of health and growth of domestic animals, their diet must be well balanced; basic feed often needs to be enriched with respect to trace and minor elements. Such additions are made on the basis of results of the analysis of the raw material. To control the quality of the analyses of all these materials and products, the Community Bureau of Reference (BCR) has produced various CRMs e.g. Natural Moroccan phosphate rock (CRM 32), Superphosphate (CRM 33), K(2)SO(4) fertiliser (CRM 114), KCl fertiliser (CRM 113), Calcium-ammonium nitrate fertiliser (CRM 178), Urea fertiliser (CRM 179), Calcareous loam soil (CRM 141), Light sandy soil (CRM 142), Sewage sludge amended soil (CRM 143), Hay powder (CRM 129), Rye grass (CRM 281), and Olive leaves (CRM 62). Their main characteristics are described and the certified values of some major, minor or trace elements are given. In addition, the BCR has also certified trace and toxic elements in three sewage sludges (CRM 144, 145 and 146).
