Ngokuthuthuka okusheshayo kobuchwepheshe bezolimo obunembayo, abalimi abaningi e-United States sebeqalile ukusebenzisa izinzwa zenhlabathi ezisebenza ngezindlela eziningi ukuze bathuthukise ukukhiqizwa kwezolimo. Muva nje, idivayisi ebizwa ngokuthi "inzwa yenhlabathi engu-7-in-1" iqalise ukuhlanya emakethe yezolimo yase-US futhi isiphenduke ithuluzi "lobuchwepheshe abamnyama" abalimi abazama ukulithenga. Le nzwa ingaqapha kanyekanye izinkomba eziyisikhombisa ezibalulekile zomhlabathi, okuhlanganisa umswakama, izinga lokushisa, i-pH, ukuhanjiswa, okuqukethwe kwe-nitrogen, okuqukethwe kwe-phosphorus kanye nokuqukethwe kwe-potassium, okuhlinzeka abalimi ngedatha yezempilo yenhlabathi ebanzi.
Umkhiqizi wale nzwa uthe idivayisi isebenzisa ubuchwepheshe obuthuthukisiwe be-inthanethi Yezinto (IoT) ukuze idlulisele idatha kumakhalekhukhwini womsebenzisi noma ikhompuyutha ngesikhathi sangempela. Abalimi bangabuka izimo zenhlabathi ngokusebenzisa isicelo esihambisana naso futhi balungise ukuvundisa, ukuchelela kanye nezinhlelo zokutshala ngokusekelwe emininingwaneni. Isibonelo, lapho inzwa ithola ukuthi okuqukethwe kwe-nitrogen emhlabathini ayanele, uhlelo luzokhumbuza ngokuzenzakalelayo umsebenzisi ukuthi angeze umanyolo we-nitrogen, ngaleyo ndlela agweme inkinga yokufaka umanyolo ngokweqile noma ukuntuleka kwemisoco.
UMnyango Wezolimo wase-US (i-USDA) uyakweseka ukukhuthazwa kwalobu buchwepheshe. Umkhulumeli waphawula: “Inzwa yenhlabathi engu-7-in-1 iyithuluzi elibalulekile lokulima ngokunemba, ayikwazi nje ukusiza abalimi ukwandisa isivuno, kodwa futhi yehlise ukumoshwa kwezinsiza futhi inciphise umthelela endaweni ezungezile.” Eminyakeni yamuva nje, uMnyango Wezolimo wase-US ubulokhu ukhuthaza ukusungulwa kobuchwepheshe bezolimo ukuze kuncishiswe ukusetshenziswa kukamanyolo namanzi kuyilapho uthuthukisa isivuno nekhwalithi yezitshalo.
UJohn Smith, umlimi wase-Iowa, ungomunye wabasebenzisi bokuqala balenzwa. Uthe: “Esikhathini esidlule, besingahlulela kuphela izimo zenhlabathi ngokusekelwe kokuhlangenwe nakho. Manje ngale datha, izinqumo zokutshala seziphenduke zesayensi.
Ngaphezu kokuthuthukisa ukusebenza kahle kokukhiqiza, inzwa yomhlabathi engu-7-in-1 nayo isetshenziswa kabanzi ocwaningweni. Amaqembu ocwaningo lwezolimo emanyuvesi amaningi e-United States asebenzisa lezi zinsiza ukwenza ucwaningo lwezempilo enhlabathini ukuze kuthuthukiswe izinqubo zezolimo ezizinzile. Isibonelo, abacwaningi baseNyuvesi yaseCalifornia, e-Davis bahlaziya idatha yezinzwa ukuze bahlole indlela yokuthuthukisa ukusetshenziswa kwamanzi ezindaweni ezikhungethwe isomiso.
Nakuba intengo yale nzwa iphakeme kakhulu, izinzuzo zayo zesikhathi eside ziheha abalimi abaningi. Ngokwezibalo, ukuthengiswa kwezinzwa eMidwest yase-United States kukhuphuke cishe ngo-40% onyakeni odlule. Abakhiqizi nabo bahlela ukwethula izinsiza zokuqasha ukuze behlise izinga lamapulazi amancane.
Abahlaziyi bakholelwa ukuthi ngokuduma kobuchwepheshe bezolimo obunembayo, amadivayisi ahlakaniphile njengenzwa yomhlabathi engu-7-in-1 azoba indinganiso yezolimo esikhathini esizayo. Lokhu ngeke kusize nje kuphela ukubhekana nezinselelo zokuvikeleka kokudla emhlabeni wonke, kodwa futhi kuzothuthukisa ezolimo ukuze zithuthuke ngendlela evumelana nemvelo futhi esimeme.
