Resumo: | The main objective of this work was to obtain updated data from soil fertility laboratories located in Portugal. A survey was sent to the Heads of 32 laboratories and a reply was received from 25 of them. 14 of these labs belong to the Ministry of Education, 7 are private and 4 to the Ministry of Agriculture. In addition to soil they also analyse plant material and, the majority, organic soil improver and irrigation water. In the minimum package of analyses they offer (Summary Analysis) pH, organic matter, extractable phosphorus and potassium are always included and 72 % of them also include field texture. But this package differs greatly between labs with regard to the inclusion of other parameters. 76 % of the labs issue fertilisation recommendations, but only 20 % do so automatically. There is a relative homogeneity of methods for the parameters of the summary analysis, except for organic matter. Only two laboratories have accredited tests. The existence of a national interlaboratory test is felt to be important for internal quality control and harmonisation of methodologies. |

Enviou-se um inquérito aos responsáveis técnicos de 32 laboratórios, tendo recebido resposta de 25 deles. 14 destes lab. pertencem ao Ministério da Educação, 7 são privados e 4 do Ministério da Agricultura. Para além de solo analisam também material vegetal e, a maioria, corretivos orgânicos e águas de rega. No pacote mínimo de análises que oferecem (Análise sumária) todos analisam o pH, matéria orgânica, fósforo e potássio extraíveis e, em 72 % deles, também a textura de campo. Mas este pacote difere muito entre laboratórios no tocante à inclusão de outros parâmetros. 76 % dos laboratórios emitem recomendações de fertilização, mas apenas 20 % o fazem automaticamente. Existe relativa homogeneidade de métodos para os parâmetros da análise sumária, exceto no tocante à matéria orgânica. Apenas dois laboratórios têm ensaios acreditados. A existência de um teste Interlaboratorial nacional é sentida como importante para o controlo interno de qualidade e harmonização de metodologias.Sociedade de Ciências Agrárias de Portugal2023-02-26info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.19084/rca.28476por2183-041X0871-018XMano, RaquelRebelo, Fernandainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-03-02T08:30:48Zoai:ojs.revistas.rcaap.pt:article/28476Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T16:47:25.587540Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
