<\/a>\"45654587\"<\/a>D\u00e9terminer le pH de votre sol permet savoir s’il est alcalin ou au contraire acide. L’\u00e9chelle va de 0 \u00e0 14, le pH \u00e9gal \u00e0 7 \u00e9tant consid\u00e9r\u00e9 comme neutre. Au del\u00e0 de 7, le sol est alcalin, par contre en dessous de 7 le sol est consid\u00e9r\u00e9 comme acide.<\/p>\n

La plupart des plantes pr\u00e9f\u00e8rent un sol l\u00e9g\u00e8rement acide, et on consid\u00e8re qu’on sol dont le pH est compris entre 6,5 et 7,2 est id\u00e9al.<\/p>\n

1. Est-ce que c’est important de conna\u00eetre le pH de son sol ?<\/em><\/strong><\/p>\n

Oui, car le pH influe sur la disponibilit\u00e9 des \u00e9l\u00e9ments nutritifs pour les plantes que l’on cultive. <\/p>\n

"Par exemple<\/a>, les plantes de bruy\u00e8res, comme les rhododendrons, ont besoin de beaucoup de fer. C’est un oligo-\u00e9l\u00e9ment dont la disponibilit\u00e9 augmente avec l’acidit\u00e9 du sol. Dans un sol alcalin, le rhododendron sera atteint de chlorose ferrique<\/a>."<\/p>\n

2. Comment le mesurer ?<\/em><\/strong> <\/p>\n

Il existe des kits sp\u00e9ciaux permettant de mesurer le pH de votre sol. Plus le r\u00e9sultat est orang\u00e9 rouge, plus votre sol est acide. Plus il est bleu-vert, plus votre sol est alcalin.<\/p>\n

3. Comment le modifier, l’am\u00e9liorer ?<\/em><\/strong><\/p>\n

– Si votre sol est trop acide, cela signifie qu’il manque de phosphore et qu’il a besoin d’un peu de chaux.<\/p>\n

– Si votre sol est trop alcalin, un peu de tourbe le rendra plus acide. Si cela n’est pas suffisant, l’ajout de la fleur de soufre devrait am\u00e9liorer son pH.<\/p>\n
