Ungashintsha kanjani inhlabathi pH

Umhlabathi ubaluleke kakhulu ezitshalweni, hhayi ize, kuwo kukhona amaminerali adinga kakhulu ukuze akhule. Kepha kwesinye isikhathi sithola inhlabathi ene-esidi kakhulu noma ene-alkaline kakhulu, okuthi, kunokuvumela izimpande ukuthi ziyimunce, kubenze babe buthakathaka, bebeka engcupheni impilo yezitshalo. Ingabe lokhu kungavinjelwa nganoma iyiphi indlela ukuthi kungenzeki?

Ngenhlanhla, yebo. Kunento eyodwa esingayenza ukuze kube nensimu enhle noma ingadi yezithelo kulowo mhlaba. Ngalokho, kufanele wazi ungashintsha kanjani inhlabathi pH, into esizokuchazela yona ngokulandelayo.

Uyini umehluko phakathi kwenhlabathi ene-alkaline ne-asidi eyodwa?

Ngaphambi kokwazi ukuthi ungayishintsha kanjani i-pH, kubalulekile ukuthola ukuthi kungani kufanele siyishintshe.

Inhlabathi ene-alikhali

Uma sinenhlabathi ene-alikhali, okungukuthi, izwe eline-pH engu-7 noma ngaphezulu, ezinye izitshalo bazoba nokushoda kwamaminerali abaluleke njenge-iron, ithusi, i-manganese ne-zinc. Ngaphezu kwalokho, lolu hlobo lomhlabathi lunokuthambekela kokuminyaniswa kakhulu, okuvimba amanzi ukuthi angakhiphi ngokushesha ngangokunokwenzeka.

Inhlabathi ene-asidi

Uma sinomhlabathi one-asidi, okungukuthi, umhlaba one-pH engaphansi kuka-7, inkinga ezinye izitshalo ezihlangabezana nayo yilokho ayitholi - noma ayikwazi ukumunca - i-phosphorus, i-calcium, i-boron, i-molybdenum noma i-magnesium, okuyizimbiwa ezibalulekile ekukhuleni kwayo.

Ungayishintsha kanjani i-pH yenhlabathi?

Inhlabathi ene-alikhali

Lapho sifuna ukushintsha i-pH yenhlabathi ene-alikhali ukuyenza ibe ne-esidi ethe xaxa, singasebenzisa okulandelayo:

• Isulfure eyimpuphu: umphumela uhamba kancane (kusuka ezinyangeni eziyisithupha kuye kweziyisi-6), kepha ukushibhile kakhulu yilokho okusetshenziswa kakhulu. Kufanele sengeze u-8 kuye ku-150g / m250 bese sihlangana nenhlabathi, futhi sikala i-pH ngezikhathi ezithile.
• Insimbi sulphate: inomphumela osheshayo kunesibabule, kepha kuyadingeka ukukala i-pH ngoba singasehlisa ngokweqile kunesidingo. Umthamo wokwehlisa i-pH 1 degree ingu-4 amagremu wensimbi enesulfed ngelitha ngalinye lamanzi.
• Peat Blond: ine-pH ene-asidi kakhulu (3.5). Kufanele sibeke u-10.000-30.000kg / ha.

Inhlabathi ene-asidi

Ngakolunye uhlangothi, lapho sifuna ukukhulisa i-pH yenhlabathi ene-asidi, singasebenzisa okulandelayo:

• I-limestone yaphansi: kufanele siyisakaze futhi siyixube nomhlaba.
• Amanzi anamanzi: Kunconywa kakhulu ukukhulisa i-pH kuphela emakhoneni amancane.

Kunoma ikuphi kufanele silinganise i-pH, ngoba uma sikhula izitshalo acid (amabalazwe aseJapan, camellias, njll.) futhi siphakamisa i-pH ibe ngaphezu kuka-6, ngokushesha bazokhombisa izimpawu ze-chlorosis ngenxa yokushoda kwe-iron.

Ngakho-ke ungatshala izitshalo ozifunayo engadini yakho noma engadini yezithelo 🙂.
