Ngokuthuthuka okusheshayo kobuchwepheshe bezolimo obunembile, abalimi abaningi e-United States sebeqalile ukusebenzisa izinzwa zomhlabathi ezisebenza ngezindlela eziningi ukuze bathuthukise umkhiqizo wezolimo. Muva nje, idivayisi ebizwa ngokuthi “inzwa yomhlabathi engu-7-in-1” idale ukukhanga emakethe yezolimo yase-US futhi isibe ithuluzi “lobuchwepheshe obumnyama” abalimi abazama ukulithenga. Le sensor ingaqapha ngesikhathi esisodwa izinkomba eziyisikhombisa ezibalulekile zomhlabathi, okuhlanganisa umswakama, izinga lokushisa, i-pH, ukuhanjiswa kwamandla, okuqukethwe yi-nitrogen, okuqukethwe yi-phosphorus kanye nokuqukethwe kwe-potassium, okuhlinzeka abalimi ngedatha ephelele yempilo yomhlabathi.
Umkhiqizi walesi senzwa uthe idivayisi isebenzisa ubuchwepheshe obuthuthukisiwe be-Internet of Things (IoT) ukudlulisa idatha kuselula yomsebenzisi noma kwikhompyutha ngesikhathi sangempela. Abalimi bangabuka izimo zenhlabathi ngokusebenzisa uhlelo oluhambisanayo futhi balungise umanyolo, ukuchelela kanye nezinhlelo zokutshala ngokusekelwe kudatha. Isibonelo, lapho inzwa ithola ukuthi okuqukethwe yi-nitrogen enhlabathini akwanele, uhlelo luzokhumbuza umsebenzisi ngokuzenzakalelayo ukuthi afake umanyolo we-nitrogen, ngaleyo ndlela agweme inkinga yokuvundisa ngokweqile noma izakhamzimba ezinganele.
UMnyango Wezolimo wase-US (i-USDA) usekela ukukhuthazwa kwalolu buchwepheshe. Okhulumela uthe: “Inzwa yomhlabathi engu-7-in-1 iyithuluzi elibalulekile kwezolimo ezinembile. Ayikwazi nje ukusiza abalimi ukwandisa isivuno, kodwa futhi inciphise ukuchithwa kwezinsizakusebenza futhi inciphise umthelela emvelweni.” Eminyakeni yamuva nje, uMnyango Wezolimo wase-US ubulokhu ukhuthaza ukusungula izinto ezintsha kwezobuchwepheshe bezolimo ukuze kuncishiswe ukusetshenziswa komanyolo namanzi ngenkathi kuthuthukiswa isivuno sezitshalo kanye nekhwalithi.
UJohn Smith, umlimi wase-Iowa, ungomunye wabasebenzisi bokuqala balesi senzwa. Uthe: “Esikhathini esidlule, besikwazi ukwahlulela izimo zenhlabathi kuphela ngokusekelwe kokuhlangenwe nakho. Manje ngale datha, izinqumo zokutshala seziye zaba zesayensi kakhulu. Ngonyaka odlule, isivuno sami sommbila sanda ngo-15%, kanti ukusetshenziswa komanyolo kwehle ngo-20%.
Ngaphezu kokuthuthukisa ukusebenza kahle kokukhiqiza, inzwa yomhlabathi engu-7-in-1 isetshenziswa kabanzi ocwaningweni. Amaqembu ocwaningo lwezolimo emanyuvesi amaningi e-United States asebenzisa la madivayisi ukwenza ucwaningo lwezempilo yomhlabathi ukuthuthukisa imikhuba yezolimo eqhubekayo. Isibonelo, abacwaningi eNyuvesi yaseCalifornia, eDavis bahlaziya idatha yezinzwa ukuze bahlole ukuthi bangayisebenzisa kanjani kangcono ukusetshenziswa kwamanzi ezindaweni ezikhungethwe yisomiso.
Nakuba intengo yale sensor iphakeme kakhulu, izinzuzo zayo zesikhathi eside ziheha abalimi abaningi ngokwengeziwe. Ngokwezibalo, ukuthengiswa kwezinzwa eMidwest ye-United States kukhuphuke cishe ngo-40% ngonyaka odlule. Abakhiqizi bahlela nokuqalisa izinsizakalo zokuqasha ukuze banciphise umkhawulo wamapulazi amancane.
Abahlaziyi bakholelwa ukuthi ngokwandiswa kobuchwepheshe bezolimo obunembile, amadivayisi ahlakaniphile njengenzwa yomhlabathi engu-7-in-1 azoba yindinganiso yezolimo zesikhathi esizayo. Lokhu ngeke kusize nje kuphela ekubhekaneni nezinselele zokuphepha kokudla emhlabeni jikelele, kodwa futhi kuzokhuthaza ezolimo ukuthi zithuthuke ngendlela enobungani nemvelo futhi eqhubekayo.
