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.

 Mmetụta na ala 
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.Turner, R.C. and Clark J.S., 1966, Lime potential in acid clay and soil suspensions. Trans. Comm. II & IV Int. Soc.

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 
Mmetụta zuru oke nke ala liming na carbon organic nke ala bụ isi ihe sitere na usoro atọ. 

 Mmụba nke mmepụta ihe ọkụkụ na-akpata nnukwu ihe ọkụkụ. Ka ala liming na-eme ka ọnọdụ ala dị mma nke na-egbochi uto osisi, a na-atụ anya mmụba nke mmepụta osisi. 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. 
 Mmụba nke mineralisation nke ihe ndị dị ndụ n'ihi pH dị mma. 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.
 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.
