Emakhasini aphakathi kwekhulu leshumi nesishiyagalolunye, ukufuduka kwezolimo e-United States kwabona abalimi abaningi beqala ukususa indawo engenalutho, beya ngasentshonalanga emathafeni naseningizimu-ntshonalanga, ngokulandelana. Njengoba ezolimo zifuduka, abalimi baqaphela kakhulu isimo sezulu esishintshayo, okwaphawula ushintsho kancane kancane lusuka ezindaweni ezinamahlathi esifundeni esisempumalanga ukuya esimweni sezulu esomile sotshani entshonalanga. Umehluko wamazinga okushisa nendawo yendawo ubangele izitshalo nemikhuba ehluke kakhulu kulezi zindawo ezimbili. Ngaphambi kokuba izwe ligezwe, lalinamatshe futhi lingenamanzi. Ngenkathi ezolimo zingena, ukuntuleka kwamathuluzi namasu okulima asetshenziswa endaweni kwakusho ukuthi umhlaba omningi wawungenamuntu futhi wawungenamuntu. Ukuze bajwayelane nesimo esisha sokutshala, abalimi abaningi baqala ukufaka ucingo oluhlabayo ezindaweni zabo zokutshala.
Ngenxa yokufuduka besuka empumalanga baye entshonalanga, inani elikhulu labantu ukuhlinzeka ngezinto zokusetshenziswa, by the empumalanga yokuqala baye bakha izindonga zamatshe, inqubo yokufudukela entshonalanga futhi bathola izihlahla eziningi ezinde, uthango lokhuni futhi kusukela eluhlaza. izinto zokwakha kule ndawo kancane kancane zanda eningizimu, ngaleso sikhathi umsebenzi oshibhile futhi uvumele ukwakhiwa kube lula kakhulu, kodwa engxenyeni esentshonalanga ngenxa yetshe nezihlahla aziningi kakhulu, ucingo aluzange lubekwe kabanzi. Kodwa entshonalanga ekude, lapho amatshe nezihlahla kwakungekuningi khona, ukubiya kwakungenziwa kabanzi.
Ezinsukwini zakuqala zokubuyiselwa komhlaba, ngenxa yokuntuleka kwezinto zokwakha, umqondo wendabuko wabantu wezicijile ungadlala indima yokuzivikela emingceleni yabo kusuka kwamanye amandla angaphandle ukuze abhubhise futhi anyathelwe yizilwane, ngakho-ke umqondo wokuvikela unamandla kakhulu.
Ngenxa yokuntuleka kwezinkuni namatshe, abantu baqala ukufuna ezinye izindlela zokubiya ukuze bavikele izilimo zabo. Ekuqaleni kwawo-1860 nawo-1870, abantu baqala ukutshala izitshalo ngameva ukuze kubiyelwe, kodwa kwaba nemiphumela engemihle ngenxa yokushoda kwezitshalo, intengo yazo ephezulu, kanye nokuphazamiseka kokwakha uthango, bashiywa. Ukuntuleka kokubiyelwa kwenza uhlelo lokukhuculula umhlaba lungaphumeleli. Kwaze kwaba ngo-1873 lapho ucwaningo olusha lwashintsha isimo sabo esibucayi lapho u-DeKalb, e-Illinois, esungula ukusetshenziswa kocingo oluhlabayo ukuze kugcinwe umhlaba wabo. Kusukela manje kuqhubeke, ucingo oluhlabayo lusanda kungena emlandweni wemboni.
Inqubo yokukhiqiza nobuchwepheshe.
E-China, izimboni eziningi ezikhiqiza izintambo ezihlabayo zisebenzisa izintambo zikathayela noma izintambo zepulasitiki ezinamekwe ngokuqondile ocingweni oluhlabayo. Le ndlela yokuluka nokusonta ucingo oluhlabayo yandisa ukusebenza kahle kokukhiqiza, kodwa ngezinye izikhathi iba nenkinga yokuthi ucingo oluhlabayo alulungisiwe ngokwanele. Ngokuthuthuka kobuchwepheshe, manje kukhona abakhiqizi abathile abaqala ukusebenzisa ukwengezwa kwenqubo ethile ye-crimping, ukuze ubuso bocingo bungabi yindilinga ngokuphelele, okuthuthukisa kakhulu ukuqiniswa kocingo oluhlabayo.
