Emahlathini asenkabazwe, kwakhiwa inhlabathi ye-ferralite ebomvu-phuzi nebomvu, igcwele i-aluminium nensimbi, enikeza umhlaba umbala obomvu. Lolu hlobo lwenhlabathi lwenzeka esimweni sezulu esiswakeme nesifudumele nezimo zezulu. Ngokuyinhloko, izinga lokushisa lonyaka elijwayelekile lapha lingu- +25 degrees Celsius. Ngaphezulu kwamamilimitha ayi-2 500 emvula ewela minyaka yonke.
Inhlabathi ebomvu-ophuzi
Inhlabathi ebomvu ye-ferralite ilungele ukukhula kwezihlahla emahlathini asenkabazwe. Lapha izihlahla zikhiqiza kakhulu. Ngenkathi yomsebenzi obalulekile, umhlaba ugcwele izinhlanganisela zamaminerali. Inhlabathi yeFerralite iqukethe ama-humus angama-5%. I-morphology yenhlabathi ebomvu-ophuzi imi kanjena:
- Udoti wasehlathini;
- ungqimba lwe-humus - lulele ngamasentimitha ayi-12-17, lunemibala e-brown-grey, ephuzi futhi ebomvu nsundu, iqukethe udaka;
- idwala lomzali elinikeza umbala obomvu omnyama enhlabathini.
Inhlabathi ebomvu
Umhlabathi obomvu obomvu wenziwa ngemvula emaphakathi efinyelela kuma-millimitha ayi-1800 ngonyaka futhi uma kunenkathi eyomile okungenani izinyanga ezintathu. Emhlabathini onjalo, izihlahla azikhuli kakhulu, futhi ezingxenyeni ezingezansi inani lezihlahla notshani obuhlala njalo luyanda. Lapho kufika inkathi eyomile, umhlaba uyoma futhi uvezwe yimisebe ye-ultraviolet. Lokhu kunikeza inhlabathi umbala obomvu ogqamile. Isendlalelo esiphambili sinombala onsundu onsundu. Lolu hlobo lomhlabathi luqukethe cishe ama-4-10% ama-humus. Lo mhlabathi ubonakala ngenqubo yokwenziwa kwesikhathi. Ngokuya ngezici, umhlaba obomvu wakhiwa emadwaleni obumba, futhi lokhu kunikeza ukuzala okuphansi.
Izinhlobo ezingaphansi kwenhlabathi
Inhlabathi yeMargelite itholakala emahlathini asenkabazwe. Akhiwe ngobumba futhi aqukethe inani elincane lama-asidi. Ukuzala kwalo mhlabathi kuphansi kakhulu. Inhlabathi ye-Ferralite gley nayo iyatholakala emahlathini asenkabazwe. Lawa angamanzi anosawoti kakhulu futhi adinga ukukhishwa. Akuzona zonke izinhlobo zezimbali ezingakhula kuzo.
Kuyathakazelisa
Emahlathini ase-equatorial, inhlabathi ye-ferralite yenziwa ikakhulukazi - ebomvu nebomvu-ophuzi. Bacebiswe ngensimbi, i-hydrogen ne-aluminium. Lo mhlaba ulungele izinkulungwane zezinhlobo zezitshalo, ikakhulukazi lezo ezidinga ukufudumala njalo nomswakama. Ngenxa yokuthi imvula ina njalo emahlathini asenkabazwe, ezinye izakhi zomzimba zigezwa ziphele enhlabathini, okushintsha kancane ukwakheka kwayo.
