PH inomiririra 'hydrogen inogona' uye chiyero cheyero yehydrogen ions (H +) kune hydroxyl ions (OH-), mune mamwe mazwi, ivhu pH kukosha chiyero chekisheni yeion inochengetwa nevhu zvidimbu uye organic zvinhu.
Chiyero chepH chinotangira pa0 kusvika 14, iine pH 7 kwazvakarerekera. Kuverengwa pazasi pe7.0 kunoratidza kuti ivhu "acidic" uye kuverenga pamusoro 7.0 kunoratidza mamiriro "alkaline" evhu.
Sei pH yakakosha?
Zvizhinji zvezvirimwa zvinogona kutsungirira yakakura pH renji mune mhinduro tsika, asi haigone kutsungirira huwandu hwakasiyana hweasidhi muvhu.
Kana acidity yevhu yashanduka, iyo solubility yesimbi dzakasiyana siyana ion inoshandukawo. Kukura kwezvirimwa kunokanganiswa nekusangana kwakasiyana kwesimbi idzi mumhinduro, kwete neacityity pachayo.
PH yevhu yakakosha, nekuti inokanganisa huwandu hwevhu zvinhu zvinokanganisa kukura kwezvirimwa.
Izvi ndizvo:
Utachiona hwevhu
Basa rebhakitiriya rinoburitsa nitrogen kubva kune yakasikwa zvinhu uye mamwe mafetiraiza anonyanya kukanganiswa nePH yepasi, nekuti mabhakitiriya anoshanda zvakanyanya mupH renji ye5.5 kusvika 7.0.
Nutrient leaching
Dyara zvinovaka muviri zvichibuda muvhu riine pH iri pasi pe5.0 nekukurumidza zvakanyanya kupfuura ivhu rine hunhu pakati pe5.0 na7.5.
Nutrient kuwanikwa
Dyara michero inowanzo kuwanika kune zvirimwa mu pH renji kubva pa5.5 kusvika 6.5.
Zvinhu zvine chepfu
Aluminium inogona kuve chepfu yekudyara kukura mune imwe ivhu ine pH iri pasi pe5.0.
Chimiro chevhu
Chimiro chevhu, kunyanya ivhu, chinokanganiswa nePH. Mune yakakwana pH renji (5.5 kusvika 7.0), ivhu revhu rakaumbana uye rinoshanda nyoreIpo kana ivhu pH rakanyanya acidic kana yakanyanyisa alkaline, ivhu rinowanzo kuve rakanamatira uye rakaoma kukura.
Iyo ivhu pH bvunzo inoratidza kuti ivhu rako rinozoburitsa kukura kwakanaka kwezvirimwa kana kuti kana richizoda kurapwa kuti rigadzirise huwandu hwePH. Kune mazhinji zvirimwa, iyo yakanakisa pH renji iri 5.5 kusvika 7.0, asi mune dzimwe nguva, zvimwe zvirimwa zvinokura mune ivhu rakawandisa kana zvinoda imwe alkaline nhanho.
Ivhu pH bvunzo
Ivhu pH inogona kusaenzana nezvikonzero zvakasiyana, senge Kuenderera mberi kwekushandisa inorganic mafetiraiza kunoita kuti ivhu riwedzere kuva rakachenesa
Kiti yekuyedza makiti inowanikwa munzvimbo zhinji dzekutengesa gadheni, anosanganisira ekuyedza machubhu uye nemakemikari mhinduro yekusanganisa nevhu. Nzira iri nyore kushandisa pH sensor.
Nokuti ivhu iri semi-solidIwo akanyanya sensors ane pfumo-rakagadzirwa girazi, iro rinotendera vashandisi kuboora pasi pevhu pasina kutyora probe.
Imwe nzira yekuyera pH ndeyekutora ivhu kemisitiri mumushonga wemvura. Iwe unosanganisa ivhu nemvura mune 1: 1 ratio, kubvumira kuyerwa kwesampula yemvura uchishandisa yakajairwa pH electrode.
Ruramisa ivhu pH
Acidic ivhu rinochinjwa ne lime: kusimudza pH yevhu uye kutapira kana kuita ivhu alkaline. Tarisa pamhedzisiro yevhu rako bvunzo kuti uone kana iwe uchida calcite kana dolomitic lime.
Calcite calcite
Inotorwa kubva zvakasikwa limestone deposits uye inopwanyika kana pasi kuti iwane hupfu hwakatsetseka. Inonzi zvakare kurima lime.
Dolomitic lime
Inowanikwa nenzira yakafanana, asi kubva kumatombo emarara ane calcium uye magnesium.
Kana iwe uchida kudzikisa iyo pH yevhu alkaline kune iyo acid renji, shanduko kune elemental sarufa kana aluminium sulfate.
Elemental sarufa
Inoiswa kubindu, uye inozopedzisira yaiswa oxidase nehutachiona muvhu. Zvinotora mwedzi mishoma kugadzirisa pH.
Aluminium sulfate: inogadzira shanduko inokurumidza muvhu pH.
