Liming (ala)
Liming bụ ntinye nke calcium- (Ca) na magnesium (Mg) bara ụba n'ụdị dị iche iche, gụnyere marl, nzu, limestone, lime ọkụ ma ọ bụ lime hydrated na ala.[1]. Na ala acid, ihe ndị a na-emeghachi omume dị ka ntọala ma na-ewepụ acidity ala. Nke a na-emekarị ka uto osisi dịkwuo mma ma na-abawanye ọrụ nke nje bacteria na ala, [1] mana oke ibu nwere ike ịkpata mmerụ ahụ na ndụ osisi. Buru ụzọ liming nke oge a site na marling, usoro nke ịgbasa nzu na ahịhịa nzu n'ofe ala, na mbọ iji gbanwee pH ma ọ bụ mkpokọta nha.[2] Ihe akaebe nke omume ndị a malitere na 1200 ma were ihe atụ ndị mbụ sitere na agwaetiti Britain nke oge a.[1]
Mmetụta na ala
[dezie | dezie ebe o si]Liming nwekwara ike melite mkpokọta nkwụsi ike na ala ụrọ. N'ihi na nke a nzube Ọdịdị wayo, ngwaahịa nwere calcium oxide (CaO) ma ọ bụ hydroxide (Ca (OH) 2) na mixes na calcium carbonate (CaCO3), na-ejikarị. Nhazi ihe owuwu nwere ike ibelata mfu nke ụrọ na nri sitere na mkpokọta ala.[3] Ogo nke a na-enye ego lime kwa nkeji nke oke ala ga-abawanye pH ala dabere na ikike nchekwa nke ala (nke a na-emetụtakarị ikike mgbanwe ala ma ọ bụ CEC).
A na-ejupụta ọtụtụ ala acid na aluminum karịa hydrogen ion. N'ihi ya, acidity nke ala bụ nsonaazụ hydrolysis nke aluminum.[2] Echiche a nke "ike lime a na-edozi" iji kọwaa ogo nke isi saturation na ala ghọrọ ihe ndabere maka usoro eji eme ihe ugbu a na ụlọ Nnyocha ala iji chọpụta "ihe lime chọrọ" nke ala. [3][4]
Ala nwere CEC dị ala ga-egosipụtakarị mmụba pH karịa ala nwere CEC dị elu. Mana ala CEC dị ala ga-ahụ ngwa ngwa nke ndabere ndị agbakwunyere, ya mere ọ ga-ahụ nloghachi ngwa ngwa na acidity mbụ ọ gwụla ma emere mgbakwunye ọzọ. O yikarịrị ka ịkpụcha ihe gabigara ókè ga-eme n'ala nwere obere CEC, dị ka ájá nke na-enweghị ihe mgbochi dị ka ihe ndị dị ndụ na ụrọ.
Mmetụta na carbon sitere n'ala

Mkpụrụ osisi dị elu nke sitere na itinye lime ga-emepụta nloghachi dị ukwuu nke ihe ndị dị ndụ n'ala n'ụdị mgbọrọgwụ na-anwụ anwụ na ihe ọkụkụ na-emebi emebi. [6]

A maara ngwa ngwa lime ka ọ na-enwe mmetụta na-akpali akpali n'oge na-adịghị anya na ọrụ nke ihe ndị dị ndụ n'ala, si otú a na-akwado mineralization nke ihe ndị sitere n'okike ma o yikarịrị ka ọ na'ịgba ọsọ ọsọ nke ihe ndị ahụike n'ala.[7]
- Ime ka ọdịdị ala dịkwuo mma na-eduga na mbelata nke mineralization site na ichebe carbon nke ala. A maara Liming ka ọ dịkwuo mma, dịka oke Ca2+ na ike ion dị elu na ihe ngwọta ala na-eme ka flocculation nke mineral ụrọ dịkwuo elu ma, n'aka nke ya, mepụta ihe ndị ọzọ siri ike. [6]
