\"\"En raison des pr\u00e9cipitations abondantes de ces derniers mois, nous constatons de grandes diff\u00e9rences dans la structure du sol des parcelles pr\u00e9vues pour betteraves et chicor\u00e9es, parfois m\u00eame au sein d\u2019une m\u00eame exploitation.

L\u00e0 o\u00f9 la r\u00e9colte de la culture pr\u00e9c\u00e9dente s’est d\u00e9roul\u00e9e dans des conditions difficiles et o\u00f9 aucun travail du sol n’a pas pu \u00eatre effectu\u00e9 de mani\u00e8re optimale jusqu’\u00e0 pr\u00e9sent, on constate souvent des compactages. Sur d’autres surfaces, on constate une bonne structure du sol gr\u00e2ce \u00e0 un travail du sol adapt\u00e9 et au bon d\u00e9veloppement des cultures interm\u00e9diaires, en interaction avec les gel\u00e9es de la mi-janvier.<\/p>\n

Un test \u00ab\u00a0\u00e0 la b\u00eache\u00a0\u00bb est important pour se faire une id\u00e9e de la structure du sol et pour d\u00e9cider de l’intensit\u00e9 n\u00e9cessaire du travail du sol ! La couche superficielle doit s\u2019\u00e9mietter (lit de germination) et la terre en profondeur ne doit pas rester en un bloc compact si vous la jeter devant vous (un sol humide est plus sensible au compactage). Il est important de ne pas transf\u00e9rer le tassement vers des zones humides plus profondes. Les erreurs de travail ont une influence n\u00e9gative sur la lev\u00e9e et le d\u00e9veloppement ult\u00e9rieur des racines au d\u00e9triment du rendement.<\/p>\n","protected":false},"excerpt":{"rendered":"
