Njengomphakeli ochwepheshe wamaphasela kamanyolo namaphakheji kamanyolo, sizibophezele ekuhlinzekeni ngemikhiqizo yekhwalithi ephezulu engagcini nje ngokukhuthaza ukukhula kwezitshalo kodwa futhi ecabangela umthelela wemvelo wokusetshenziswa kwazo. Omunye wemikhiqizo esemqoka ohlwini lwemikhiqizo yethu i-ammonium chloride, umanyolo we-potassium (K) odlala indima ebalulekile ekwenzeni ngcono isivuno kanye nekhwalithi yezitshalo ezitshalwa emhlabathini ongenazo izakhamzimba. Kulezi zindaba, sizobhekisisa izici zamakhemikhali zeammonium chloride usawotifuthi uhlole umthelela wazo endaweni ezungezile.
Izici zamakhemikhali ze-ammonium chloride:
I-Ammonium chloride, ifomula yamakhemikhali i-NH4Cl, usawoti oyikristale oncibilika kakhulu emanzini. I-hygroscopic, okusho ukuthi imunca umswakama ovela emkhathini. Lesi sakhiwo sikwenza kube umthombo obalulekile we-nitrogen ekuvundiseni izitshalo ngoba incibilika kalula futhi imuncwe izimpande zezitshalo. Ukwengeza, i-ammonium chloride iphezulu ku-nitrogen, okwenza kube umthombo osebenzayo wezakhi ezibalulekile ekukhuleni kwezitshalo.
Uma i-ammonium chloride isetshenziswa enhlabathini, ingena kwinqubo ebizwa ngokuthi i-nitrification, lapho amabhaktheriya asenhlabathini eguqula i-nitrogen ngendlela ye-ammonium (NH4+) ibe yi-nitrate (NO3-). Lokhu kuguqulwa kubalulekile ngoba izitshalo ngokuyinhloko zimunca i-nitrogen ngendlela yama-nitrate. Ngakho-ke, i-ammonium chloride isebenza njengenqolobane ye-nitrogen engakhululwa kancane kancane futhi isetshenziswe izitshalo ngokuhamba kwesikhathi.
Umthelela we-ammonium chloride endaweni ezungezile:
Ngenkathii-ammonium chlorideungumanyolo osebenzayo, ukusetshenziswa kwawo kungaba nomthelela emvelweni uma kungaphathwa ngendlela efanele. Enye yezinto ezikhathazayo kakhulu ukuthi kungenzeka ukucwiliswa kwe-nitrogen. Ukusetshenziswa ngokweqile kwe-ammonium chloride noma omunye umanyolo osekelwe ku-nitrogen kungabangela i-nitrate emanzini angaphansi komhlaba, kubangele ubungozi eqophelweni lamanzi kanye nemvelo yasemanzini.
Ukwengeza, inqubo ye-nitrification enhlabathini iholela ekukhishweni kwe-nitrous oxide (N2O), igesi enamandla ebamba ukushisa enomthelela ekushintsheni kwesimo sezulu. Kubalulekile ukuthi abalimi kanye nabasebenzi bezolimo basebenzise izindlela zokuphatha ezingcono kakhulu zokunciphisa ukulahleka kwe-nitrogen futhi banciphise umthelela wemvelo wokufakwa kwe-ammonium chloride.
Ukusetshenziswa okuqhubekayo kwe-ammonium chloride:
Ukuze kubhekwane nokukhathazeka kwezemvelo okuhambisana nayoammonium chloride usawoti, kubalulekile ukwamukela izinqubo ezizinzile ekusetshenzisweni kwayo. Lokhu kubandakanya ukuphathwa okunembayo kwezakhi, okulungisa amazinga okufakwa kwezidingo ezidingweni ezithile zezitshalo ezitshalwayo. Ukwengeza, ukuhlanganisa izinqubo ezifana nokunqampuna kwekhava, ukujikeleziswa kwezitshalo, kanye nokusetshenziswa kwe-nitrification inhibitors kungasiza ekunciphiseni ukuvuza kwe-nitrogen futhi kunciphise ukukhishwa kwegesi ebamba ukushisa.
Kafushane, i-ammonium chloride ingumanyolo obalulekile we-potassium onomthelela omkhulu ekondlekeni kwezitshalo nasekukhuleni. Kodwa-ke, izakhiwo zayo zamakhemikhali nemithelela yemvelo kufanele kuqondwe ukuze kuqinisekiswe ukusetshenziswa kwayo okufanele. Ngokukhuthaza izindlela ezisimeme zezolimo kanye nokuqwashisa ngokusetshenziswa okufanele kwe-ammonium chloride, singasebenzisa izinzuzo zayo kuyilapho sinciphisa indawo yayo yemvelo. Njengomphakeli onomthwalo wemfanelo, sizibophezele ekwesekeni amakhasimende ethu ukuthi asebenzise umanyolo ngendlela ehambisana nemvelo, okunomthelela empilweni yesikhathi eside ye-ecosystem yethu.
