Izinzwa zenhlabathi ezinamandla: Ukuvula inkathi entsha yokulima ngokunemba

Enqubweni yesimanje yezolimo, amandla esayensi nobuchwepheshe ahlala elungisa indlela yokulima evamile. Njengamanje, kuvela inzwa yenhlabathi ene-capacitive emisha, enezinzuzo zayo eziyingqayizivele yobuchwepheshe ilethe izinguquko ezingakaze zibonwe emkhiqizweni wezolimo, futhi kancane kancane iba ngumuntu ongakwesokudla kuningi labalimi ukwandisa ukukhiqiza nokwandisa imali engenayo futhi bathole intuthuko esimeme.

Ukubona okunembile, shayela ukweqa kokukhiqiza
Endaweni yokutshala okusanhlamvu e-United States, abalimi babevame ukwahlulela izimo zenhlabathi ngolwazi, futhi imiphumela yokutshala yayixutshwa. Ngokwethulwa kwezinzwa zomhlabathi ezine-capacitive, isimo sahlehliswa ngokuphelele. Inzwa isebenzisa isimiso se-capacitive sensing ukuqapha umswakama wenhlabathi, usawoti, i-pH nezinye izinkomba ezibalulekile ngesikhathi sangempela ngokunemba okukhulu. Isibonelo, endaweni yokutshala ummbila, inzwa iyazwela kusawoti omningi wendawo wenhlabathi, futhi abalimi balungisa ngokushesha isu lokunisela ngokusho kwempendulo, bakhulise umzamo wokukhukhula, futhi banciphise ukuvinjelwa kukasawoti ekukhuleni kommbila. Ngesikhathi sokuvuna, ukukhiqizwa kommbila esifundeni kwakuphakeme ngo-28% kunonyaka odlule, futhi okusanhlamvu kwakugcwele futhi kuyikhwalithi enhle. Lo mphumela omangalisayo ubonisa ngokugcwele ikhono elivelele lezinzwa zenhlabathi ezinamandla ukuze ziqondise ngokunembile ukutshala futhi zifinyelele ekukhiqizeni okuphezulu komhlaba.

Ukuthuthukisa izinsiza ukuze kwehliswe izindleko zokukhiqiza
Ukulawulwa kwezindleko kuyisixhumanisi esibalulekile sokusebenza kwezolimo. Ensimini yemifino eCambodia, umnikazi wayo wayekhungathekile ngenxa yezindleko eziphakeme zokunisela nokufaka umanyolo. Ukusetshenziswa kwe-capacitive inhlabathi inzwa kube yisihluthulelo sokuqeda inkinga. Ukuqapha okunembile komswakama wenhlabathi yizinzwa kwenza ukuchelela kungasaboni. Lapho umswakama womhlabathi ungaphansi komkhawulo wesidingo sezitshalo, uhlelo lokunisela oluzenzakalelayo luqala ngokunembile futhi lulungise inani lamanzi ngobuhlakani ngokusekelwe kudatha yezinzwa, ukugwema ukumoshwa kwemithombo yamanzi. Mayelana nokuvundiswa, idatha yezakhi zomhlabathi ezinikezwa yizinzwa zasiza abalimi ukuthi bafake umanyolo lapho bedingeka, behlisa ukusetshenziswa kukamanyolo ngamaphesenti angama-22. Ngale ndlela, ngenkathi yehlisa izindleko zokukhiqiza, ipaki inomphumela ozinzile wemifino kanye nekhwalithi engcono, futhi ibone ukukhuliswa kwezinzuzo zezomnotho.

Intuthuko eluhlaza ukumelana nokushaqeka kwesimo sezulu
Njengoba sibhekene nenselelo ekhulayo yokuguquka kwesimo sezulu, intuthuko eqhubekayo yezolimo isiseduze. Kwesinye isifunda sezithelo e-Australia, isimo sezulu esibi kakhulu siye sakuthinta kakhulu ukukhula kwezihlahla zezithelo. Izinzwa zenhlabathi ezinamandla zidlala indima ebalulekile lapha. Phakathi nezinkathi zokushisa okuphezulu nesomiso, inzwa ilandelela izinguquko kumswakama wenhlabathi ngesikhathi sangempela, futhi abalimi bagcwalisa amanzi ezihlahleni zezithelo ngesikhathi, banciphise ngempumelelo umthelela wesomiso. Ngemuva kwezimvula ezinamandla nezikhukhula, inzwa iphendula ngokushesha inhlabathi ye-pH kanye nezinguquko zokungena komoya, futhi abalimi bathatha izinyathelo zokuthuthukisa ngokufanele ukuze baqinisekise impilo yezimpande zesihlahla sezithelo. Ngosizo lwezinzwa, ukukhiqizwa kwezithelo endaweni yokukhiqiza kuhlala kuzinzile esimweni sezulu esibi kakhulu, kuyilapho kunciphisa ukungcoliswa kwemvelo okubangelwa ukuchelela nokuvundiswa okungenangqondo, futhi kukhuthaze ukuthuthukiswa kohlaza nokusimeme kwezolimo.

Ochwepheshe bezolimo ngokuvamile bakholelwa ukuthi izinzwa zenhlabathi ezinamandla ziholela ezolimo enkathini entsha yokutshala ngokunemba ngokusebenza okunembile kokuqapha, imiphumela ephawulekayo yokunciphisa izindleko kanye nokwesekwa okuqinile kwentuthuko esimeme. Ngokukhuthazwa okubanzi kanye nokusetshenziswa kwalobu buchwepheshe, kulindeleke ukuthi kuthuthukiswe ngokugcwele ukusebenza kahle kanye nekhwalithi yokukhiqizwa kwezolimo, kudale izinzuzo eziningi kubalimi, futhi kuvikelwe imvelo yezolimo. Kukholakala ukuthi esikhathini esizayo esiseduze, izinzwa zenhlabathi ezinama-capacitive zizoba izinga elibalulekile ekukhiqizweni kwezolimo, zisize imboni yezolimo ukuthi ifinyelele igxathu elisha eliya phambili.
