Umhlabathi ofanele uyadingeka ukuze izitshalo zikhule kahle. Esinye sezinkomba eziyinhloko zemixube yenhlabathi yi-asidi. Lo mqondo usetshenziselwa ukwenza ukuhlaziywa kwe-agrochemical kwama-substrates, kanye nokuchaza izici zezakhi zawo (ngokwesibonelo, umhlaba wesoyi, i-peat, i-humus nezinye izinto).
Buyini ubumuncu bomhlabathi?
Ubumuncu bomhlabathi bunqunywa inani le-pH. Kungenxa ye-asidi efanele ukuthi isitshalo sithola ama-macro kanye nama-microelements adingekayo. Ezingeni elithile le-pH, inhlabathi ingathathi hlangothi, i-alkaline, ne-acidic.
Kukho konke ukuphila kwayo, ummeleli wezimbali ukhula enhlabathini ethile, eshintsha njalo i-asidi yayo. Ngakho-ke, lapho ukulima kukhulu kakhulu esizeni, kulapho-ke sekune-oxidized. Umhlabathi ongathathi hlangothi (pH 7.0) uphakathi kwezinto ezithandwa kakhulu izitshalo.
Uma abamele izimbali bekhula enhlabathini ene-asidi (i-pH engaphansi kuka-5.0), izakhamzimba azisadonswa yizinto eziphilayo. Ngaphezu kwalokho, umphumela womanyolo awubonwa, futhi umphumela wamagciwane azuzisayo unciphisa noma ume ngokuphelele.
Uma izitshalo zisenhlabathini ene-alkaline (i-pH engaphezu kuka-7.5), bese zinciphisa ukukhula kwazo, okuthinta amaqabunga, ziqala ukuba phuzi ngenxa yokushoda kwensimbi (isici sokulandela umkhondo asimunciswanga).
Ukunqunywa kwezinga le-asidi
Kunezindlela eziningi ezingasiza ekunqumeni ubumuncu bomhlabathi:
- Iphepha leLitmus liwumkhiqizo osebenziseka kalula okulula ukuwusebenzisa. Umhloli udinga ukuthatha amasampula omhlabathi amaningana, ngemuva kwalokho kufanele abekwe endwangwini eminyene. Okokusebenza kufanele kucwiliswe emanzini (mhlawumbe kuhlanzwe) bese kuthi ngemuva kwemizuzu emihlanu iphepha le-litmus kufanele licwiliswe lapho. Ngemuva kwemizuzwana emi-2, umphumela uzobonakala. Leli phepha liguqula umbala walo ngaphansi kwethonya loketshezi (isikali se-asidi sinamathele kumkhiqizo).
- Indlela yesintu ukubeka inani elincane lomhlabathi engilazini. Ngaphezu kwalokho, insiza ithelwa ngeviniga (9%). Uma ukusabela kubonakala ngesimo sokwakheka kwe-foam, lokhu kusho ukuthi inhlabathi ine-alkaline; uma isisindo se-bubble sincane kakhulu, kubhekwa ukuthi inhlabathi ayithathi hlangothi. Ukungabikho kwe-foam kukhombisa ungqimba olungaphezulu lwe-acidic koqweqwe lomhlaba.
- Umbono wesazi - imvamisa isimo senhlabathi singahlolwa ngokubukeka. Ngakho-ke, izindawo ezine-asidi ephezulu zinombala omhlophe, i-clover noma i-alfalfa ikhula kabi kuzo, kanti ubulembu buhluma ngokuphawulekayo. Enhlabathini ene-asidi, ukhula, i-whitebear, i-pike, i-buttercup ezinwabuzelayo nezinye izitshalo zizizwa zihle.
Ukuze uqonde ukuthi hlobo luni lomhlabathi olusendaweni yakho, ungakhulisa ama-beet etafuleni. Nge-acidity eyandisiwe yenhlabathi, imifino izoba namaqabunga abomvu, ngamaqabunga angathathi hlangothi - aluhlaza anama-petioles abomvu, ane-alkaline - imicu emaqabungeni e-shades akhanyayo.
Izinsimbi zokulinganisa
Abenzi benze izinto ezikhethekile zokusiza ukukala ubumuncu bomhlabathi. Lawa madivayisi ashibhile futhi agcina umnikazi wesayithi kusuka kuzinqubo ezidla isikhathi nezinzima. Amadivayisi afakwe iphenyo elide elikuvumela ukuthi ungene ngokujulile enhlabathini futhi uhlole i-asidi emazingeni ehlukene. Uma udinga ukwazi isimo senhlabathi kanye, akunangqondo ukuthenga okokusebenza.
Yini okufanele ibe yi-asidi yenhlabathi?
Kubalulekile ukuqonda ukuthi isitshalo ngasinye singesomuntu ngamunye, futhi zonke izinhlobo zidinga i-asidi yomhlabathi ehlukile. Noma kunjalo, inketho enhle kakhulu (futhi eyamukelekayo ezinhlotsheni eziningi zabamele izimbali) ithathwa njengomhlabathi ongathathi hlangothi (amabanga we-pH kusuka ku-7.0 kuye ku-7.3).
