Ikakhulukazi esetshenziselwa ukolweni, ummbila, irayisi nezinye izitshalo zasensimini, kanye nezihlahla zezithelo, imifino nezimbali nezinye izitshalo ezidinga ukunikezwa kwesikhathi eside kwezakhi. Umanyolo oyinhlanganisela uwuhlobo lukamanyolo oluqukethe i-nitrogen, i-phosphorus, i-potassium nezinye izakhamzimba ngokulingana. Inezinzuzo zokuqukethwe okuphezulu kwezakhi, izingxenye ezimbalwa kanye nezakhiwo ezinhle zomzimba, ezingahlangabezana nezidingo zokukhula kwezitshalo futhi zikhuthaze isivuno esiphezulu nesizinzile sezitshalo.
3. Izinhlelo zokusebenza zokusika zerobhothi eziguquguqukayo ezisezingeni eliphezulu ezintathu-ntathu, ukufeza umsebenzi wokusika i-bevel, ipayipi nethoshi usebenzisa umsebenzi wokumisa i-servo.
Ingakwazi ukusika insimbi ye-carbon steel, insimbi engagqwali, ithusi, i-aluminium namanye amapayipi namaphrofayili, anjengalawa: ithubhu, ipayipi, ipayipi le-oval, ipayipi elingunxande, i-H-beam, i-I-beam, i-engeli, isiteshi, njll. Idivayisi isetshenziswa kabanzi ohlotsheni oluhlukahlukene lwenkundla yokucubungula iphrofayili yamapayipi, imboni yokwakha imikhumbi, isakhiwo senethiwekhi, insimbi, ubunjiniyela basolwandle, amapayipi kawoyela nezinye izimboni.
