I te tata haere mai o ngā rā o te maramataka ki te kotinga, ka tukuna e ngā kaipāmu o DTN Taxi Perspective ngā pūrongo ahunga whakamua, me te matapaki i te āhua o tā rātou whakatau i ngā…
REDFIELD, Iowa (DTN) – Ka raru pea ngā namu i ngā kahui kau i te kōanga me te raumati. Mā te whakamahi i ngā mana whakahaere pai i te wā tika ka āwhina i te whakatutuki i te hokinga mai o te haumi.
"Ka taea e ngā rautaki whakahaere riha pai te āwhina i te whakarato i te whakahaere whai hua," te kī a Gerald Stokka, he rata kararehe nō Te Whare Wānanga o North Dakota State me te tohunga whakahaere kararehe. Ko te tikanga o tēnei ko te whakahaere tika i te wā tika me te roanga tika.
"I te wā e whāngai ana i ngā kuao kau, kāore e whai hua te whakahaere i ngā kutu me ngā pepeke namu i mua i te whāngai kararehe, ā, ka ngaro pea ngā rauemi whakahaere pepeke," te kī a Stoica. "Ko te wā me te momo whakahaere pepeke ka whakawhirinaki ki te momo namu."
Ko ngā namu haona me ngā namu moana kāore e puta mai tae noa ki te tīmatanga o te raumati, ā, kāore e eke ki te paepae ōhanga mō te whakahaere tae noa ki waenganui o te raumati. He hina ngā namu haona, ā, he rite ki ngā namu whare iti te āhua. Ki te kore e āraihia, ka taea e rātou te whakaeke i ngā kararehe tae atu ki te 120,000 ngā wā i te rā. I ngā wā pīrahi, tae atu ki te 4,000 ngā namu pere ka taea te noho i runga i te hiako kau kotahi.
I kī a Elizabeth Belew, he tohunga kai kararehe i Purina Animal Nutrition, mā ngā ngārara pere anake ka taea te utu i te umanga kararehe o Amerika tae atu ki te $1 piriona ia tau. "Ka taea e te whakahaere i ngā ngārara kau i te tīmatanga o te wā te hanga rerekētanga nui ki te whakahaere i ngā taupori puta noa i te wā," tana kī.
"Mā te ngau tonu ka mamae, ka ahotea hoki ngā kau, ā, ka taea hoki te whakaiti i te taumaha o te kau kia 20 pauna te taumaha," te tāpiri a Stokka.
He rite te āhua o ngā namu kanohi ki ngā namu whare nui, pouri. He namu kore ngau ēnei, ā, e kai ana i ngā paru kararehe, i te waihonga tipu me ngā wai paru. Ka taea e ēnei namu te pangia ngā kanohi o ngā kau, ā, ka puta te mate kiriuhi kanohi. Ko te nuinga o te wā ka piki ake te maha o ēnei namu i te mutunga o te raumati.
He rite te rahi o ngā namu pūmau ki ngā namu whare, engari he tohu porowhita kei a rātou hei wehewehe i a rātou mai i ngā namu haona. Ka kai toto ēnei namu, ka ngau i te puku me ngā waewae. He uaua ki te whakahaere i a rātou mā te whakamahi i ngā hua i maringi, i werohia rānei.
He maha ngā momo whakahaere rere, ā, ka pai ake te mahi a ētahi i ētahi atu i raro i ētahi āhuatanga. E ai ki a Belew, ko te huarahi whai hua, watea hoki ki te whakahaere i ngā namu haona puta noa i te wā rere ko te whāngai i ngā kohuke kei roto ngā kaiwhakahaere tipu pepeke (IGR), e tika ana mō ngā momo kau katoa.
"Ina kainga te kohuke e ngā kau kei roto te IGR, ka haere mā roto i te kararehe ka uru ki roto ki ngā paru hou, ka whānau mai ngā hua o ngā rango wahine pakeke. Ka ārai te IGR i ngā pupa kia kore ai e whanake hei rango pakeke ngau," tana whakamārama. He pai ake te whāngai i ngā rā 30 i mua i te huka whakamutunga i te puna, me ngā rā 30 i muri i te huka tuatahi i te ngahuru kia tino eke te kai a ngā kararehe ki ngā taumata e hiahiatia ana.
I kī a Colin Tobin, he kaipūtaiao kararehe i te Carrington Research Center o NDSU, he mea whai hua te tirotiro i ngā tarutaru hei whakatau ko ēhea ngā namu kei reira me ō rātou taupori. He kōwhiringa pai ngā pine taringa, kei roto ngā patupatu ka tukuna mārire ki roto i te huruhuru o te kararehe i a ia e neke ana, engari kaua e whakamahia kia teitei rawa te taupori namu i waenganui o Hune ki Hūrae, e ai ki a ia.
E taunaki ana ia kia pānuihia ngā tapanga, nā te mea ka rerekē pea ngā rahinga hei whakamahi, te pakeke o ngā kau e whakahuatia ana, me te taumata matū o te matū hohe. Me tango ngā tapanga ina kore e whai mana.
Ko tētahi atu huarahi whakahaere ko te whakamahi i ngā matū me ngā rehu ki ngā kararehe. I te nuinga o te wā ka pania tika ki te tihi o te kararehe. Ka mimitia te matū, ka rere puta noa i te tinana o te kararehe. Ka taea e ēnei rongoā te whakahaere i ngā ngārara tae atu ki te 30 rā i mua i te whakamahinga anō.
"Mō te whakahaere tika i ngā ngaro, me riringi ngā rehu i ia rua, i te toru wiki rānei puta noa i te wā rere," te kī a Tobin.
I ngā wā e whakamahia ana ngā pepeke, ko ngā tikanga tino whai hua mō te whakahaere i ngā namu ko ngā kai kohikohi puehu, ngā tauera tuara me ngā ipu hinu. Me whakanoho ēnei ki ngā wāhi e maha ana te urunga atu o ngā kararehe, pērā i ngā puna wai, ngā wāhi whāngai rānei. Ka whakamahia te paura, te wai rānei hei patu pepeke. E whakatūpato ana a Bellew me tirotirohia pinepine ngā taputapu rokiroki patu pepeke. Kia mōhio ngā kararehe he āwhina tēnei ki a rātou, ka tīmata rātou ki te whakamahi i ngā taputapu i ngā wā katoa, e ai ki tāna.
