Inzwa yeTheralytic inceda amafama alawule ukufakwa kwesichumiso

Itekhnoloji ye-Smart sensor eya kunceda amafama asebenzise isichumisi ngokufanelekileyo kwaye anciphise umonakalo wokusingqongileyo.
Ubugcisa, obuchazwe kwiphephancwadi iNatural Foods , bunokunceda abavelisi babone elona xesha lifanelekileyo lokugalela isichumiso kwizityalo nomlinganiselo wesichumiso esifunekayo, beqwalasela iimeko ezifana nemozulu nomhlaba. Oku kuya kunciphisa ukuchumisa komhlaba okunexabiso eliphezulu nokonakaliswa kokusingqongileyo, okukhupha igesi yegreenhouse nitrous oxide ize ingcolise umhlaba nemijelo yamanzi.
Namhlanje, ukuchumisa ngokugqithisileyo kubangele ukuba i-12% yomhlaba owawulinywa emhlabeni ungasetyenziswa, kwaye ukusetyenziswa kwezichumiso zenitrogen kunyuke ngama-600% kule minyaka ingama-50 idlulileyo.
Nangona kunjalo, kunzima kubavelisi bezityalo ukulawula ngokuchanekileyo ukusetyenziswa kwabo kwesichumiso: kakhulu kwaye babeka emngciphekweni wokonakalisa okusingqongileyo kunye nokuchitha imali encinci kwaye babeka emngciphekweni wesivuno esisezantsi;
Abaphandi kwitekhnoloji entsha ye-sensor bathi inokuba luncedo kokusingqongileyo kunye nabavelisi.
Inzwa, ebizwa ngokuba yi-paper-based chemically functionalized gas sensor sensor (chemPEGS), ilinganisa inani le-ammonium emhlabeni, i-compound eguqulwa ibe yi-nitrite kunye ne-nitrate yibhaktheriya yomhlaba. Isebenzisa uhlobo lobukrelekrele bokwenziwa obubizwa ngokuba ngumatshini wokufunda, ukudibanisa nedatha kwimozulu, ixesha ukusukela ekufakweni kwesichumisi, imilinganiselo ye-pH yomhlaba kunye ne-conductivity. Isebenzisa le datha ukuqikelela isiqulatho sisonke senitrogen emhlabeni ngoku kunye nesiqulatho sisonke senitrogen kwiintsuku ezili-12 kwixesha elizayo ukuqikelela elona xesha lilungileyo lokugalela isichumiso.
Uphononongo lubonisa indlela esi sisombululo sitsha esinexabiso eliphantsi sinokunceda abavelisi ukuba bafumane inzuzo enkulu kwixabiso elincinci lesichumisi, ngakumbi kwizityalo ezisebenzisa izichumisi ezifana nengqolowa. Le teknoloji inganciphisa ngaxeshanye iindleko zomvelisi kunye nomonakalo wokusingqongileyo kwizichumisi zenitrogen, olona hlobo lusetyenziswa kakhulu lwesichumisi.
Umphandi okhokelayo uGqr Max Greer, weSebe leBioengineering kwiKholeji yase-Imperial yaseLondon uthe: “Ingxaki yokuchumisa ngokugqithisileyo, ngokwembono yemekobume nezoqoqosho, ayinakubaxa, imveliso nengeniso enxulumene noko iyehla unyaka nonyaka, kulo nyaka, yaye abavelisi okwangoku abanazo izixhobo ezifunekayo ukuhlangabezana nalo mbandela.
“Itekhnoloji yethu inganceda ekucombululeni le ngxaki ngokunceda abalimi baqonde amanqanaba akhoyo eammonia nenitrate emhlabeni baze baqikelele amanqanaba exesha elizayo ngokusekwe kwimeko yemozulu.” Oku kubavumela ukuba balungelelanise ukufakwa kwesichumiso sabo kwiimfuno ezithile zomhlaba nezityalo zabo.
Isichumiso senitrogen esigqithisileyo sikhupha i-nitrous oxide emoyeni, igesi yegreenhouse ephindwe kangangama-300 ngaphezu kwekharbon diokside kwaye inegalelo kwintlekele yemozulu. Isichumiso esigqithisileyo sisenokukhukuliseka ngamanzi emvula ukuya kwimijelo yamanzi, nto leyo ethintela ubomi basemanzini ioksijini, ibangele ukuqhakaza kwealgae kunye nokunciphisa intlobo-ntlobo zezinto eziphilayo.
Nangona kunjalo, ukulungelelanisa ngokuchanekileyo amanqanaba ezichumisi ukuze zihambelane neemfuno zomhlaba kunye nezityalo kuhlala kungumngeni. Uvavanyo lunqabile, yaye iindlela zangoku zokulinganisa initrogen yomhlaba ziquka ukuthumela iisampulu zomhlaba elabhoratri—inkqubo ende nebiza imali eninzi eziphumo zayo zingasebenzi ngokulinganiselweyo xa zifikelela kubalimi.
UGqr Firat Guder, umbhali ophezulu kunye nomphandi okhokelayo kwiSebe le-Bioengineering le-Imperial, uthe: "Uninzi lokutya kwethu kuvela emhlabeni - sisixhobo esingahlaziyekiyo kwaye ukuba asiyikhuseli siya kulahlekelwa." Kwakhona, kudibaniswa nongcoliseko lwe-Nitrogen oluvela kwezolimo kudala i-conundrum kwiplanethi eyonyusayo enethemba lokunceda ekunciphiseni ukukhula kwezityalo kunye nethemba lokukhulisa isivuno ngokuchaneka kwezolimo, kunye nokunceda ukukhulisa isivuno . iingeniso.”
