A legt\u00f6bb n\u00f6v\u00e9ny semleges vagy enyh\u00e9n savas talajban (pH 5,8\u20136,5) fejl\u0151dik a legjobban.

M\u00e9sz<\/h2>\n\n

A m\u00e9sz, vagy kerti m\u00e9sz, a talajsavasod\u00e1s cs\u00f6kkent\u00e9s\u00e9re haszn\u00e1lt leggyakoribb talajjav\u00edt\u00f3.

A hidrat\u00e1lt m\u00e9sz gyorsan emeli a pH-t, de reakci\u00f3k\u00e9pess\u00e9ge miatt k\u00f6r\u00fcltekint\u0151en kell kezelni.<\/p>\n\n

Dolomit<\/h2>\n\n

A dolomit mind kalciumot, mind magn\u00e9ziumot tartalmaz, ellent\u00e9tben a kalcittal, amely csak kalciumot tartalmaz. Mindk\u00e9t t\u00edpus\u00fa m\u00e9sz egyform\u00e1n semleges\u00edti a talajsavasod\u00e1st, de a dolomitet gyakran pellet\u00e1lt form\u00e1ban \u00e9rt\u00e9kes\u00edtik.<\/p>\n\n

Z\u00f6lds\u00e9geskertekn\u00e9l a talajt \u0151sszel vagy t\u00e9len kell m\u00f3dos\u00edtani a tavaszi \u00fcltet\u00e9s el\u0151tt.

Ker\u00fclj\u00fck a m\u00e9sz kijuttat\u00e1s\u00e1t nedves nyarakon, mivel v\u00edzre van sz\u00fcks\u00e9ge a reakci\u00f3hoz, \u00e9s id\u0151be telik, am\u00edg megv\u00e1ltoztatja a talaj pH-j\u00e1t.<\/p>\n\n

A talaj pH-j\u00e1t befoly\u00e1sol\u00f3 t\u00e9nyez\u0151k<\/h3>\n\n

K\u0151zet t\u00edpusa:<\/strong> A savas gr\u00e1nitk\u0151zet hozz\u00e1j\u00e1rul a savas talajhoz, m\u00edg a l\u00fagos pala vagy m\u00e9szk\u0151 a l\u00fagos talajhoz.<\/p>\n\n

GYIK<\/h3>\n\n

A sz\u00f3dabikarb\u00f3na emeli a talaj pH-j\u00e1t?<\/h2>\n\n

A sz\u00f3dabikarb\u00f3na \u00e1tmenetileg n\u00f6velheti a talaj pH-j\u00e1t, de nem aj\u00e1nlott hossz\u00fa t\u00e1v\u00fa megold\u00e1sk\u00e9nt, mivel meg\u00e9getheti a n\u00f6v\u00e9nyeket.<\/p>\n\n

Mely f\u00e1k kedvelik a magas pH-t?<\/h2>\n\n

A Judasfa \u00e9s a h\u00e1rsfa azok k\u00f6z\u00e9 a f\u00e1k k\u00f6z\u00e9 tartozik, amelyek elviselik vagy kedvelik a l\u00fagos talajt.<\/p>\n\n

Mi t\u00f6rt\u00e9nik, ha nem emelem a talaj pH-j\u00e1t?<\/h2>\n\n

Ha azonban a talaj nem t\u00falzottan savas, akkor lehets\u00e9ges olyan n\u00f6v\u00e9nyeket termeszteni, amelyek a savas k\u00f6r\u00fclm\u00e9nyeket kedvelik.<\/p>","protected":false},"excerpt":{"rendered":"
