Te Pānga o te pH ki te Tipu o te Tipu
Pendahuluan
Ko te pH, arā, ko te "pūmanawa o te Hauwai," he ine i te waikawa, te kawakore rānei o tētahi otinga, e whakaaturia ana i runga i te tauine mai i te 0 ki te 14. He mea nui tēnei tauine i roto i ngā mara pūtaiao maha, tae atu ki te ahuwhenua. I runga i tēnei tauine, ko te uara o te 7 e kiia ana he koretake, ko ngā uara i raro iho i te 7 he waikawa, ā, ko ngā uara i runga ake i te 7 he taketake (kawakore). I roto i te horopaki o te tipu o te tipu, he mea nui te pH o te oneone.
Me whai āhuatanga motuhake ngā tipu mō te tipu pai rawa atu, ā, ko te pH o te oneone he āhuatanga taiao nui e pā ana ki te wātea o ngā matūkai, te mahi a ngā moroiti o te oneone, me ngā taunekeneke i waenga i ngā huānga matū i roto i te oneone. Ka whakamāramahia e tēnei tuhinga te pānga o te pH ki te tipu o ngā tipu, me pēhea hoki te whakahaere i ngā mahi hei whakahaere i te pH o te oneone.
Te Mārama ki te pH me tōna Hononga ki te Oneone
He tohu nui te pH o te oneone mō tōna waikawa, tōna kawakore rānei. He nui te kukū o ngā iona hauwai i roto i te oneone he iti te pH (waikawa), engari he nui ake te kukū o ngā iona hauwai i roto i te oneone he nui te pH (kawakore). Ka tupu pai te nuinga o ngā tipu i te pH i waenga i te 5,5 me te 7,5.
Ka pā te pH o te oneone ki te wātea o ngā matūkai me ngā moroiti o te oneone. I ngā taumata pH tino nui (tino waikawa, tino kawakore rānei), ka iti ake te wātea o ngā matūkai nui ki ngā tipu, ka noho rānei ki roto. Nō reira, ka pāngia pea ngā tipu e te korenga o ngā matūkai ahakoa kei roto i te oneone ēnei matūkai.
Te Pānga o te pH ki te Wātea o ngā Matūkai
He nui te pānga o te pH ki te wātea o ngā matūkai i roto i te oneone. Anei ētahi tauira matua:
– I te pH 5,5 – 7, ka taea e ngā tipu te uru atu ki ngā matūkai nui pēnei i te hauota (N), te whākōkī (P), me te pāhare pāporo (K).
– Hei tauira, ko te whākōkī te mea e tino wātea ana i te pH i waenga i te 6,0 me te 7,0. I te pH iti (waikawa), ka mau te whākōkī hei kohuke, ā, ka uaua ki ngā tipu te uru atu.
– Ko ngā matūkai moroiti pēnei i te rino (Fe) me te manganese (Mn) he nui ake te wātea i roto i ngā oneone waikawa, engari i roto i ngā oneone kawakore ka iti ake te wātea, ka hua ake te korenga o ngā matūkai moroiti i roto i ngā tipu.
Nō reira, ka pāngia te tipu o ngā tipu e ngā piki me ngā heke iti o te pH o te oneone mā te whakarerekē i te wātea o ngā matūkai i roto i te oneone.
Te Pānga o te pH ki te Mahi a ngā Moroiti
Ka pāngia hoki ngā moroiti oneone e te pH. Ko ngā huakita, e whai kawenga ana mō ngā tukanga nui o te oneone pērā i te pirau o ngā mea rauropi me te whakapūmau hauota, he kaha ake te mahi i ngā taumata pH kūpapa ki te paku kawakore. I tetahi atu taha, ka taea e ngā harore oneone te manawanui ake ki ngā taumata pH oneone waikawa ake.
He mea nui te hapori moroiti taurite mō te hauora o te oneone me ngā tipu. Ka āwhina ēnei moroiti ki te tukunga matūkai, te whakapōrearea i ngā mea rauropi, me te whakahaere i ngā mate o te oneone. Mena he iti rawa, he teitei rawa rānei te pH o te oneone, ka taea te whakaiti i te mahi a ēnei moroiti, ka pā pea ki te hauora o te oneone me ngā tipu.
Te Pānga o te pH ki te Hanganga me te Kiato o te Oneone
Ka pā anō hoki te pH o te oneone ki te hanganga o te oneone. Hei tauira, i roto i ngā oneone waikawa, ka taea e ngā katote konumohe me te rino te whakapūpū i roto i ngā rahinga nui, ka taea ai e tēnei te whakaiti i te kaha o te oneone ki te mimiti i te wai me te hau, me te whakaiti anō hoki i te āputa o ngā pūwero. Nō reira, ka taea te whakararu i te tipu o ngā pakiaka me te whai huatanga o te mimiti wai me ngā matūkai e ngā tipu.
I tetahi atu taha, ki te tino kawakore te pH, ka piki ake te mimiti o te konupūmā ki roto i te oneone, ka hua ake he hanganga oneone mārō, kikī. Ka taea e tēnei āhuatanga te whakawhāiti i te tipu o te pakiaka me te kaha o te tipu ki te uru atu ki te wai me ngā matūkai.
Te Whakahaere i te pH o te oneone
I te mōhio ki te hiranga o te pH i roto i te tipu o ngā tipu, me aroturuki me te whakahaere i te pH o te oneone e ngā kaimahi pāmu me ngā māra. Anei ētahi mahi ka taea e koe te mahi:
1. Te Ine i te pH o te oneone:
Hei whakatau i te pH o te oneone, me whakamātautau auau i te oneone. Kei te wātea ngā kete whakamātautau pH oneone i runga i te hokohoko, ā, he tino tika ngā pānui e tukuna ana.
2. Ka whakanui ake i te pH waikawa o te oneone:
Mena he waikawa rawa te oneone, ka tāpirihia te raima (kohatu kōhatu) hei whakanui ake i te pH. Ko ngā momo raima e whakamahia whānuitia ana ko te konupūmā (konupūmā kāponāte) me te dolomite (he ranunga o te konupūmā me te konupūmā kāponāte). Ko te nui o te raima ka tāpirihia ka whakawhirinaki ki te waikawa o te oneone me tōna momo.
3. Te whakaheke i te pH o te oneone kawakore:
He uaua ake te whakaiti i te pH o te oneone tino kawakore. Ko ētahi huarahi ko te tāpiri i ngā mea rauropi pērā i te wairākau, te pīti waikawa rānei, ka āta heke te pH. Ka taea hoki te whakamahi i te whanariki, te konumohe whanariki rānei hei āwhina i te whakaheke i te pH o te oneone.
4. Te Aroturuki me te Tiaki:
Kia eke ki te pH e hiahiatia ana, me aroturuki tonu kia mau tonu ai i roto i te awhe tino pai. Me tāpirihia ngā mea rauropi i ia wā hei whakapai ake i te hanganga me te momona o te oneone.
Te Katinga
He pānga tika te pH o te oneone ki te wātea o ngā matūkai, te mahi a ngā moroiti, me te hanganga o te oneone, ā, ka whai wāhi katoa ēnei ki te hauora me te tipu o ngā tipu. Nō reira, he mea nui te mārama me te whakahaere i te pH o te oneone mō te angitu o te mahi ahuwhenua me te māra.
Ahakoa he uaua te whakahaere i te pH o te oneone, mā te māramatanga pai me ngā taputapu tika, ka taea e ngā kaimahi pāmu me ngā māra te whakarite kia tupu pai ā rātou tipu i raro i ngā āhuatanga tino pai. Ko ngā tikanga whakahaere pēnei i te whakamātautau oneone auau me te tāpiri i ngā whakatikatika oneone he rautaki nui hei whakatutuki i te taurite pH e tautoko ana i ngā tipu hauora, hua. Nō reira, ko te pH oneone pai ehara i te mea ka whai wāhi ki te hauora o ngā tipu takitahi engari ki te pumau me te kounga whānui o te rauropi oneone.
