Hona le mefuta e mengata ea mobu, eo har'a eona ho hlahang sod-calcareous. U ka kopana le mofuta ona oa mobu merung e sootho. Mobu oa mofuta ona o thehiloe hanyane ka hanyane mme hangata o ka fumanoa libakeng tse nang le calcium carbonate, ke hore, haufi le libaka tseo majoe a fapaneng a leng ho tsona (mohlala, lejoe la mokoetla, 'mabole, li-dolomite,' marl, letsopa, jj.).

Litšobotsi, matšoao le sebopeho sa mobu

E le molao, mobu o bataletseng o ka fumanoa letsoapong, sebakeng se bataletseng, libakeng tse bataletseng le tse phahameng. Mobu o ka ba tlasa moru, meambo le mefuta ea limela.

Karolo e ikhethang ea mobu oa soddy-calcareous ke litaba tse phahameng tsa humus (ho fihlela 10% kapa ho feta). Mobu o kanna oa ba le likarolo tse kang humic acid. Maemong a mangata, ha ho hlahlojoa mobu oa mofuta ona, libaka tse holimo li fana ka karabelo e sa nke lehlakore, tse tlase - alkaline; ka seoelo haholo asiti hanyane. Tekanyo ea ho se chesehe e susumetsoa ke botebo ba ketsahalo ea li-carbonate. Kahoo, maemong a phahameng, sesupo se tloha ho 5 ho isa ho 10%, maemong a tlase - ho fihlela ho 40%.

Mobu oa Soddy-calcareous o batla o ikhetha. Leha e entsoe ka tlasa limela tsa morung, lits'ebetso tse ngata tse khethollang mobu oa mofuta ona li fokolisitsoe kapa ha li eo ka botlalo. Mohlala, mobung oa soddy-calcareous, ha ho na matšoao a leaching kapa podzolization. Sena se bakoa ke taba ea hore masala a limela, a kenang mobung, a senyeha tikolohong e nang le khalsiamo e ngata.
