Ka kitea te haukinia hauota i roto i ngā kukū iti i te āhuarangi o runga. He whānuitia te whakamahinga hei tongi mō te raihi me ētahi atu hua whenua. Ko te haukinia hauota te tongi hauota tuatahi i hangaia e te tukanga Haber-Bosch, i hangaia mā te tauhohenga o te haukinia me te waikawa whanariki. He rerekē ki te tote nitrate, he pumau te matū, kāore i te tino waikura. Ka tukuna hoki e ia he whanariki tāpiri ki ngā oneone kāore pea i roto i tēnei huānga, engari he iti noa iho te uara ina whakamahia ki ngā oneone e whiwhi ana i te superphosphate noa. Ko ngā ngoikoretanga o te rauemi ko tōna iti o te ihirangi hauota, e whakanui ana i ngā utu rokiroki me te kawe, me tōna āhua kaha ki te whakakawa i te oneone, he nui ake i tērā o tētahi atu tongi hauota.
