Inethiwekhi yesivamvo somgangatho wamanzi e-Iowa igciniwe

I-Iowa State University Nutrition Research Centre iye yazisa injongo yayo yokuxhasa inethiwekhi yeenzwa zomgangatho wamanzi ukujonga ukungcoliswa kwamanzi kwimifudlana yase-Iowa kunye nemilambo, nangona iinzame zomthetho zokukhusela inethiwekhi yenzwa.
Ezi ziindaba ezimnandi kubantu base-Iowa abakhathalele ubulunga bamanzi kwaye bakholelwa ukuba badinga idatha yokuvavanya iinzame zombuso zokunciphisa i-nitrate kunye ne-phosphorus engena emanzini.Iziko loPhando lweZondlo kunye nomlawuli walo, uMat Helmers, bafanelwe ikhredithi ngokungavumeli ezopolitiko ukuba zibe nefuthe elibi kuphando lomgangatho wamanzi.
"I-Iowa Water Quality Information System sisixhobo esibalulekileyo sokuhlola umgangatho wamanzi kwilizwe kunye nokulandelela ukusebenza kwezicwangciso zokunciphisa izondlo zase-Iowa," kusho uHelmers kwi-imeyile ku-Erin Jordan weGazethi.
Ivoti yeNdlu yoWiso-mthetho ukukhusela uthungelwano yaba ngumdlalo wezopolitiko ongenambono omfutshane.Umzamo ukhokelwa nguSenendi yelizwe uRyan Dan Zumbach, umkhwenyana wakhe ophethe i-11,600-head feedlot kwi-Bloody Run Creek watershed kumntla-mpuma we-Iowa.Esinye sezivamvo ekuthethwa ngaso sasikwindawo yokutya kwi-Bloody Run Creek, umjelo wetrout ochongwe njengomzimba wamanzi ochongiweyo liSebe lezeNdalo lase-Iowa.
Ukubuyisela imali kwi-sensors kubonisa ukuhamba okucacileyo ngabaRiphabhlikhi abalawula iNdlu yoWiso-mthetho ukulawula ulwazi malunga nenkqubela yokucoca amanzi angcolileyo e-Iowa.Idatha ye-Sensor ibonisa ngokungaguquguqukiyo ukuba i-Iowa indlela yokuzithandela engqongqo yokuhlangabezana neenjongo ezichazwe kwisicwangciso sokunciphisa izondlo zombuso akubanga nenkqubela phambili ebalulekileyo.
Nangona kunjalo, kunye nokuzibophelela kwe-Iowa State, inkxaso-mali yophando usebenzisa idatha ye-sensor kwiYunivesithi yase-Iowa iya kuncipha.I-UI ifumene i-$ 375,000 kwiZiko loPhando lweZondlo ukuhlalutya idatha yenzwa kwaye ilindele ukuba loo mali inyuke ukuya kwi-$ 500,000 kunyaka olandelayo webhajethi.ngaphandle kwe.Ukuthatha inxaxheba, i-UI iya kufumana i-$ 295,000 kunyaka ozayo kunye ne-$ 250,000 kunyaka olandelayo.
Ngaloo ndlela, nangona ukuzinikela okuncomekayo kwe-Iowa, abezomthetho baseRiphabhlikhi baye baphumelela ekunciphiseni inkxaso-mali yophando.I-Iowa ilahlekile.Inkqubo ye-sensor iphethwe yi-Iowans, idatha eqokelelweyo lulwazi loluntu, kwaye iziphumo zophononongo zibonelela ngomfanekiso ocacileyo wenkqubela phambili enentsingiselo encinci eyenziweyo ekucoceni amanzi.Lo mba ubaluleke kakhulu ukuvumela abenzi bomthetho ukuba bagcine abantu base-Iowas ebumnyameni ngenxa yobudlelwane babo kwimidla emikhulu yezolimo.

Sinokubonelela ngeentlobo ezahlukeneyo zezinzwa zomgangatho wamanzi ezifana ne-ammonium nitrite, enokuthi yenziwe ngokwezifiso, wamkelekile ukubonisana.
