GRENA SUPERFER convient particuli\u00e8rement aux sols qui pr\u00e9sentent des carences en fer.
\nLa pr\u00e9sence d\u2019acides humiques et fulviques permet une stabilit\u00e9 du processus de min\u00e9ralisation qui, en leur absence, se produirait plus rapidement et donnerait lieu \u00e0 des processus de lixiviation, les acides humiques et fulviques \u00e9tant en effet responsables de la formation des complexes humat\u00e9s avec les \u00e9l\u00e9ments chimiques pr\u00e9sents dans le sol, comme par exemple: l\u2019acide humique avec le fer devient un compos\u00e9 de fer humique. Le compos\u00e9 de fer humique est reconnu par la plante et est donc plus assimilable. Les acides amin\u00e9s pr\u00e9sents naturellement sont \u00e0 leur tour des activateurs de l\u2019effet de la prolif\u00e9ration radicale et de la ch\u00e9lation qui permettent au syst\u00e8me racinaire d\u2019absorber le NPK min\u00e9ralis\u00e9 dans le sol et de favoriser la production de compos\u00e9s organiques en augmentant la capacit\u00e9 d\u2019absorption des nutriments, comme per exemple le fer.
\nC\u2019est donc pour cela que la fertilisation avec GRENA SUPERFER est essentielle pour traiter et pr\u00e9venir la chlorose ferreuse:
\n\u2022 traiter car avec GRENA SUPERFER on apporte du fer imm\u00e9diatement disponible,
\n\u2022 pr\u00e9venir car on cr\u00e9e des r\u00e9serves de fer pour les phases ph\u00e9nologiques successives de la plante.<\/p>\n","protected":false},"excerpt":{"rendered":"
