Le deuxi\u00e8me chaume de colza \u00e9tait plus clairsem\u00e9, avec moins de r\u00e9sidus, ce qui nous a permis de travailler plus superficiellement \u2014 la profondeur de travail se situait autour de 5 \u00e0 7\u202fcm. La structure du sol \u00e9tait \u00e9galement plus facile \u00e0 travailler. Avec un semoir plus performant, la parcelle serait d\u00e9j\u00e0 pr\u00eate pour le semis. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Pour la troisi\u00e8me parcelle, nous sommes pass\u00e9s sur un chaume de c\u00e9r\u00e9ales. Il \u00e9tait plus dense et plus dur que le colza, nous avons donc r\u00e9gl\u00e9 l\u2019outil \u00e0 la profondeur maximale. C\u2019\u00e9tait int\u00e9ressant : la lame a bien tranch\u00e9, travaillant \u00e0 10\u201312\u202fcm, mais la surface est rest\u00e9e tellement intacte que les blocs compacts ne faisaient que se fissurer tout en restant regroup\u00e9s en petites \u00eelots de la taille de deux paumes. Si ces blocs se brisent, la surface devient irr\u00e9guli\u00e8re. En revenant, nous avons trouv\u00e9 un r\u00e9glage permettant de maintenir une profondeur d\u2019environ 5\u202fcm. Fait surprenant : la couche sup\u00e9rieure, travaill\u00e9e plus l\u00e9g\u00e8rement, ne retenait pas les r\u00e9sidus de chaume sectionn\u00e9s, ce qui donnait une surface un peu chaotique. Malgr\u00e9 cela, l\u2019outil a coup\u00e9 environ 90\u202f% de la surface : pas de grandes fissures, une structure meuble, et les plantes rest\u00e9es en surface. Ce n\u2019est \u201cque\u201d 90\u202f%, car nous avons constat\u00e9 que 5\u202fcm est d\u00e9j\u00e0 tr\u00e8s peu : si une rigole passe sous la dent de 80\u202fcm de large, le chaume debout reste au fond de cette d\u00e9pression. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
