Ukunquma ukuthi i-acid inhlabathi isendaweni yakini, vele ubheke lezo zitshalo ozitshalayo. Ngemuva kwakho konke, uhlobo ngalunye lwe-acidity luhambelana nesembozo esithile sezitshalo. Isibonelo, inhlabathi ene-acid, equkethe umswakama omkhulu, izokulungela ukukhula kwe-meadow cornflower, i-sedge, amahhashi, i-sorrel, i-potentilla. Inhlabathi eyomisiwe futhi ene-acidic efanelekile ukukhula kweLeucanthemum, i-alfalfa, i-coltsfoot, i-clover ne-burdock. Inhlabathi ehlanganisiwe, enamaminerali ampofu izoba yindawo yezitshalo ezinjenge-mustard yasensimini, i-thistle, unyawo lwe-goose, i-euphorbia, i-chamomile ne-clover. Ukuchuma komhlaba kunganqunywa ngokuba khona kweziyize, ukhuni, isicwebezane, kanye nothi.
IhhashiUma udinga ukuthola i-acidity ngokunembile, kunconywa iphepha le-litmus. Thatha izandla ezimbalwa zomhlaba, ugcwalise ngemvula noma ngamanzi ancokiwe bese uvusa kuze kube yilapho umhlaba uphenduka iphalishi eliwuketshezi. Linda imizuzu eyishumi nanhlanu bese uxuba futhi. Ngemuva kwemizuzu emihlanu, kufakwa uketshezi ngaphezulu kwe-slurry, lapho iphepha le-litmus lizofakwa khona. Uma ucezu lwephepha luphenduka lube bomvu, khona-ke i-acidity yenhlabathi iphezulu futhi isezingeni elingaphezulu kwe-pH 5.0. Uma ukuhlolwa kwe-litmus kutholile i-tint ye-orange, khona-ke i-acidity iphakathi futhi isendaweni ye-pH ye-5.1-pH 5.5. Ukuhlolwa kwe-litmus ephuzi kukhombisa ukwakheka kancane kwe-acidic, i-acidity yayo ukusuka ku-pH 5.6 kuya ku-pH 6.0. Ucezwana oluhlaza okotshani lukhombisa inhlabathi engathathi hlangothi. Umbala oluhlaza okhanyayo wokuhlolwa kwe-litmus kusho ukuthi inhlabathi inokwakheka kwe-alkali nge-acidity ye-pH 7.1- pH8.5.
Uma ufuna ukutshala imifino, udinga ukuyitshala emhlabathini ongathathi hlangothi, ozoba sezingeni eliphezulu kakhulu.
