Ka rangahaua ngā painga o ngā potae hau me ngā ara maitai tuku iho e whakamahia ana i runga i ngā tarakihana ahuwhenua, ā, ka hangaia he take mō te pūmanawa oara rapahei whakakotahi i ngā painga o ngā mea e rua. E rua ngā whakamātautau kua pūrongohia i reira i whakaritea ai te kaha kukume o ngā ara rapa ki te kaha o ngā potae taraiwa tarakihana.

Ko te tuatahi he whakataurite i waenga i te ara rapa taraiwa waku he hanganga māmā noa iho kua whakanohoia ki roto i tētahi waka whakamātautau, me tētahi potae taraiwa tarakihana torotika tikanga. Tata ki te 25% te nui ake o te kukume i puta mai i te ara i te wira.

Ko te whakamātautau tuarua he whakataurite i waenga i tētahi mea ititaraka putungae rere ana i runga i ngā ara rapa me te tarakihana tikanga he rite te taumaha. I whakaatuhia e tēnei ka taea e ngā ara rapa tautokona pai te whakaputa i ngā āhuatanga mahi e rite ana ki ērā o ngā ara maitai. E rua ngā wā i kumea ai e te taraka te tarakihana wira i runga i ngā mahi kume rite tonu, ā, he iti ake te rutting i runga i te oneone ngohengohe.

Whakarāpopototanga（2）

I ngā wā o mua, i hangaia ngā tarakihana mō ngā ara, mō ngā wira rānei, ā, ko ngā ara te nuinga kei runga i ngā tarakihana taumaha he kaha nui. I ēnei rā, ka taea te whakahou i ngā wae ara e whā motuhake i runga i tētahi tarakihana ahuwhenua tuku iho, ka hangaia he huarahi whakamere mō te ahuwhenua. Ko te whāinga o tēnei rangahau he whakatairite i te whakakīkī oneone me te kukume mō ngā ara, ngā wira kotahi me ngā wira takirua e mau ana i runga i te momo tarakihana kotahi.

I te tau 2009, i mahia ngā inenga ki runga i ngā oneone uku e rua (Eutric Cambisols) i Huitene, mā te whakamahi i tētahi tarakihana 85 kW me te taumaha katoa o te 7700 kg. Ko te pūnaha ara rapa he ara e whā i whakanohoia ki runga i ngā toki wira tikanga o te tarakihana. He rite tonu ngā taumahatanga i inehia mō ngā ara me ngā wira takirua i ngā hohonutanga katoa i akohia (15, 30 me te 50 cm), engari he nui ake mō ngā wira takitahi i ngā hohonutanga katoa. He hononga tata ngā whakatauira o ngā taumahatanga oneone ki ngā uara i inehia mō ngā ara me ngā wira takirua, engari i whakaitihia te taumahatanga oneone i roto i te oneone mata ki ngā uara i inehia mō te wira takitahi.
