\"\"<\/a>La betterave sucri\u00e8re est une plante sensible \u00e0 un trop faible pH (pH < 6).<\/p>\n

L\u2019acidification des sols est une \u00e9volution naturelle et connue, tant dans les parcelles sous labour que celles en travail simplifi\u00e9. Les pluies importantes peuvent avoir entrain\u00e9 une baisse de pH plus cons\u00e9quente. Une chute de pH aura des cons\u00e9quences sur la croissance des cultures, mais aussi la perte de stabilit\u00e9 des sols, avec des r\u00e9percussions sur l\u2019\u00e9rosion et l\u2019asphyxie lors de fortes pr\u00e9cipitations. Cette acidification doit \u00eatre compens\u00e9e par un apport d\u2019amendement basique.<\/p>\n

Il n\u2019est pas souhaitable de corriger brusquement le pH d\u2019un sol par un apport massif, car l\u2019assimilation de certains \u00e9l\u00e9ments, dont le bore, pourrait \u00eatre bloqu\u00e9.<\/p>\n

Il est toujours souhaitable d\u2019apporter une fumure d\u2019entretien r\u00e9guli\u00e8re, tous les 4-5 ans, pour maintenir le pH dans la zone id\u00e9ale, en fonction du type de sol.<\/p>\n

L\u2019amendement peut \u00eatre r\u00e9alis\u00e9 avec plusieurs types de produits, dont les \u00e9cumes, coproduit de votre sucrerie.<\/p>\n","protected":false},"excerpt":{"rendered":"
