Kwezolimo zanamhlanje, ulawulo oluchanekileyo kunye nophuhliso oluzinzileyo ziye zaba zezona zinto ziphambili kwizazinzulu zezolimo. Ukubeka iliso kumgangatho wamanzi yinxalenye ebalulekileyo yale nkqubo, ingakumbi malunga ne-soluble carbon dioxide (CO₂). E-United States, ii-sensors ze-CO₂ zomgangatho wamanzi zisetyenziswa kakhulu kumacandelo afana nokulima izityalo eziluhlaza, ukulima amachibi, kunye neenkqubo zokunkcenkceshela. Apha ngezantsi kukho imeko ethile ebonisa ukusetyenziswa okusebenzayo kwee-sensors ze-CO₂ zomgangatho wamanzi kwezolimo zaseMelika.
Imvelaphi
Indlu enkulu yokugcina izityalo eseCalifornia igxile ekukhuliseni imifuno neentyatyambo ezixabisa kakhulu kwaye ijongene nemingeni malunga nolawulo lomgangatho wamanzi kunye nokukhula kwezityalo. Ngokuhambela phambili kubuchwepheshe bezolimo, le ndlu yokugcina izityalo isebenzise izixhobo zokubona umgangatho wamanzi ze-CO₂ ukuze kuphuculwe iimeko zokukhula kwezityalo kwaye kuphuculwe isivuno kunye nomgangatho.
Izicelo Ezisebenzayo
Ukubeka iliso kuMgangatho waManzi
Indlu eluhlaza isebenzisa ii-sensors ze-CO₂ ezisemgangathweni wamanzi ukujonga rhoqo uxinano lwe-carbon dioxide emanzini okunkcenkceshela ngexesha lokunkcenkceshela nokuchumisa. Ngokulandela amanqanaba e-CO₂ emanzini, ifama inokuqonda ngcono utshintsho kwi-asidi yamanzi (pH) kunye nemiphumo yazo ekukhuleni kwezityalo.
Inkqubo yokuNcedisa ekrelekrele
Xa izinzwa zibona ukunyuka koxinzelelo lwe-CO₂ emanzini, inkqubo ilungisa ngokuzenzekelayo ishedyuli yokunkcenkceshela. Olu hlengahlengiso oluzenzekelayo luphucula ukubonelelwa kwamanzi kunye nezondlo, luqinisekisa ukuba izityalo zikhula phantsi kweemeko ezifanelekileyo. Umzekelo, xa uxinano lwe-CO₂ luphantsi, inkqubo yonyusa amanqanaba e-CO₂ ukukhuthaza i-photosynthesis, ngaloo ndlela iphucula amazinga okukhula kwezityalo.
Uqikelelo lwesivuno sesivuno
Ngokuhlalutya idatha yembali kunye nedatha yomgangatho wamanzi ngexesha langempela, abaphathi bezindlu zokugcina izityalo banokuqikelela iindlela zokukhula kunye nesivuno esinokubakho kwizityalo zabo. Idatha enikezelwa zizinzwa ze-CO₂ zomgangatho wamanzi ixhasa ukwenziwa kwezigqibo zolawulo lwezolimo ezichanekileyo, ezifana nokucwangciswa kwexesha elifanelekileyo nokufanelekileyo kokuchumisa kunye nokunkcenkceshela.
Iziphumo kunye neNgxelo
Emva kokusebenzisa ukubekwa kweliso lomgangatho wamanzi we-CO₂, i-greenhouse ifumene ukwanda okukhulu kwemveliso. Kunyaka wokuqala wokwazisa izinzwa, isivuno sinyuke malunga ne-20%, kwaye umgangatho wezityalo nawo uphucuke kakhulu. Abaphathi baxele ukuba ukubeka esweni ngexesha langempela kunye nokulungiswa kweemeko zokunkcenkceshela kubavumele ukuba baphendule ngokukhawuleza kwimiba yokukhula, ukunciphisa inkunkuma kunye nokuphucula ukusebenza kakuhle kwemithombo yamanzi.
Amathemba Exesha Elizayo
Njengoko ubuchwepheshe bezolimo buqhubeka buhambela phambili, ukusetyenziswa kwezinzwa ze-CO₂ ezisemgangathweni wamanzi kuya kwanda ukuya kwiindawo ezininzi zezolimo, kubandakanya ukulima iintlanzi, ukujonga umhlaba, kunye nezinye iindawo zokulima izityalo. Ngokudibanisa ubukrelekrele bokwenziwa kunye nohlalutyo lwedatha enkulu, ikamva lezolimo lithembisa ukusebenza kakuhle nangokuzinzileyo, okuququzelela utshintsho kwimveliso yezolimo.
Isiphelo
Ngokusebenzisa izixhobo zokuvavanya umgangatho wamanzi ze-CO₂ kwi-greenhouse yaseCalifornia, sibona indlela ezolimo zanamhlanje ezisebenzisa ngayo iteknoloji ukuphucula ukusebenza kakuhle kwemveliso kunye nomgangatho wesivuno. Oku akuvelisi nje kuphela iingenelo ezisebenzayo kwimveliso yezolimo kodwa kukwabonelela ngengqiqo ebalulekileyo yokukhuthaza uphuhliso oluzinzileyo lwezolimo. Njengoko iteknoloji iqhubeka iphucuka, ukujonga umgangatho wamanzi kulungele ukuba sisixhobo esibalulekileyo kulawulo lwezolimo lwexesha elizayo.
