R. de A.  aEmbrapa's experience in the production and development of agriculture reference materials.h[electronic resource]  c2016  aThe main challenge of Embrapa is to develop a model of genuine Brazilian tropical agriculture and livestock. To get this task, the quality of laboratories results is mandatory, increasing the demand for reference materials. Projects were proposed to produce reference materials to support the national agriculture laboratories and consolidate a network able to perform reliable and reproducible analytical testing laboratory within the internationally standards required. Reference materials were produced and available to interested laboratories and collaborative tests were conducted to obtain consensus values. The results and statistical evaluations were performed with the use of software developed by Embrapa Pecuária Sudeste.  aagriculture  aReference materials  aSoftware1 aSOUZA, G. B. de1 aBOSSU, C.
