Crestview Valley kunali dziwe labata lomwe linali ndi kamtsinje kakang'ono, komwe kunali moyo wa Green Pastures. Kuti mbewu zawo zikhale zathanzi, Davide ankadziwa kuti madziwo ndi ofunika kwambiri, koma analibe njira yodalirika yopimira mmene mpweya wa okosijeni wasungunuka m’dziwelo. Poizoni wa minda yozungulira ndi zotsatira za kusintha kwa nyengo zinasokoneza madzi awo, zomwe zinakhudza mwachindunji zokolola zawo. Chifukwa chokhumudwa komanso kudera nkhawa za thanzi la mbewu zawo, David nthawi zambiri ankatha maola ambiri akuyesera kuona ngati madziwo ali abwino mwa kungoyerekezera.
Tsiku lina masana dzuwa litalowa, Emily anabwera akuthamanga kukwera phirilo, ndipo nkhope yake inali yosangalala. “Abambo, ndamva za masensa atsopano opangidwa ndi okosijeni osungunuka!
Chifukwa chochita chidwi koma amakayikira, David anamvetsera pamene Emily ankafotokoza mmene masensa ameneŵa amagwirira ntchito. Mosiyana ndi kuyesa kwachilengedwe komwe kumapereka zotsatira zochedwetsa komanso zofunikira ukatswiri, masensa a okosijeni osungunuka amawunikira nthawi yomweyo, kuwerengera mosalekeza. Anagwiritsa ntchito ukadaulo wapamwamba kuyeza kuwala komwe kumatengedwa ndi mamolekyu okosijeni m'madzi, kupatsa alimi zidziwitso zenizeni zenizeni zamadzi awo. Polimbikitsidwa ndi chidziwitso ichi, adaganiza zoika ndalama mu sensa.
Kupeza Kwakusintha
Ndi sensa ya okosijeni yosungunuka yomwe idayikidwa pafupi ndi dziwe, Emily adayang'anira zomwe zidachitika pa smartphone yake.

Pamene ankayang'anira madzi m'masabata otsatirawa, sensayi inawathandiza kuzindikira machitidwe ndi kusintha kwa nyengo. Chakumapeto kwa chilimwe, madzi atayamba kutenthedwa, anaona mpweya wosungunuka ukuchepa. Izi zinapangitsa kuti agwiritse ntchito zomera zokhala ndi mithunzi kuzungulira dziwe kuti aziziziritsa madzi, kupanga malo abwino okhalamo zamoyo zam'madzi ndikuwonetsetsa kuti mbewu zawo zimapeza madzi okwanira.
Zokolola Zambiri
Phindu lenileni la sensa linaonekera pa nthawi yokolola. Mbewuzo zinakula bwino kuposa kale lonse, ndipo masamba obiriŵira anaima motalikira kumbuyo kwa chigwacho. David ndi Emily anakolola zokolola zabwino kwambiri kwa zaka zambiri—chimanga cholimba, chathanzi komanso ndiwo zamasamba zomwe zinabweretsa chisangalalo pamsika wa alimi akumeneko. Alimi ochokera m’minda yoyandikana nawo anapita kwa iwo kuti adziwe chinsinsi chawo.
Emily anafotokoza monyadira kuti: “Madzi abwino ndi okosijeni amene ali m’madzi. “Ndi sensa yathu ya okosijeni ya optical dissolved, timatha kuchitapo kanthu mwamsanga tikasintha.
Nkhani itafalikira m’chigwa chonse cha Crestview, alimi ambiri anayamba kugwiritsa ntchito lusoli. Anthu ammudzi adapeza njira yatsopano yothandizira momwe amagawana deta ndi machitidwe abwino. Iwo adapanga maukonde osagwirizana kuti akambirane za ubwino wa madzi ndi zotsatira zake zosatsutsika pa thanzi la mbewu. Sanalinso kulimbana ndi mavuto awo okha; m'malo mwake, iwo anali mbali ya gulu lalikulu la kukhazikika ndi kupirira.
Tsogolo Lokhazikika
Patapita miyezi ingapo, nyengo ikayamba kutha ndiponso pamene pafamuyo inkakonzekera nyengo yozizira, David ankaganizira kwambiri za mmene angapitirire. The Optical dissolved oxygen sensor sinangosintha momwe amalima komanso idapanga kulumikizana kosatha mdera lawo. Iwo anali ochuluka kuposa alimi tsopano; anali oyang'anira chilengedwe, odzipereka kuteteza madzi awo, mbewu zawo, ndi malo omwe ankakonda.
Monyada, David ndi Emily anasonkhana m’mphepete mwa dziwelo, n’kumaonerera dzuŵa likuloŵa pamadzi amphamvuwo. Mpweya unali wamoyo ndi phokoso la chilengedwe, ndipo mbewu zinaima zolimba m’minda kumbuyo kwawo. Iwo ankadziwa kuti achitapo kanthu kuti apeze tsogolo losatha—momwe madzi abwino amabweretsa mbewu zathanzi, kuonetsetsa kuti famu yawo idzakhala ndi moyo wautali kwa mibadwo ya m’tsogolo.
Ataima pamodzi, Emily anamwetulira bambo ake kuti, “Ndani ankadziwa kuti kasensa kakang’ono kakhoza kusintha kwambiri chonchi?”
