Fiche technique Mycoagra: Prélèvement des échantillons

Les prélèvements (2-2.5Kg ; 15 x 15 x 20 cm ; Figure 1) sont réalisés à l’aide d’une bêche-plate (ou pelle-bêche) sous la couronne de noyer (aux 2/3 selon le modèle suivant ; Figure 2). Les échantillons sont ensuite conservés à 4°C (Figure 3) jusqu’au traitement (Figure 4).

    Its like you read my mind! You seem to know so much about this, like you wrote the book in it or something.
    I think that you could do with a few pics to drive the message home a
    little bit, but instead of that, this is great blog.
    A great read. I’ll certainly be back.

    site unintentionally, and I am surprised why this twist of fate did
    not took place earlier! I bookmarked it.
