Whakatūpato
He whakatau tata nō tēnei tātaitai, hei whakamōhio noa iho. E ai ki ngā tātai paerewa, ā, kāore pea e whakaata i ōu āhuatanga ake. Me kōrero ki tētahi mātanga tohu mō ōu āhuatanga ake.
Me pēhea te tātai wairākau
Horahanga × reiti ÷ 1000 = tana.
- 1
Tapeke kg
Total_kg = hectares × kg_per_ha
Urea: 200kg/ha.
- 2
Hurihia ki te tana
Tonnes = kg ÷ 1000 | Cost = tonnes × price_per_tonne
Urea: ~$800/t.
- 3
Hauota tūturu
N_applied = total_kg × N_concentration (e.g. Urea 46%)
Urea: 46% N.
Tauira
Tāuru: 10ha, 200kg Urea
Hua: 2.0t × $800 = $1,600.
Ngā Pātai Auau
Me pēhea e tātau ai i te wairākau e hiahiatia ana mō tōku pāka?
Hei tātai i te nui o te wairākau e hiahiatia ana mō tētahi pāka, whakareatia te rēti tono i roto i ngā kirikiri ia hekitia (kg/ha) ki te rahi o te pāka i roto i ngā hekitia. Hei tauira, ko tētahi rēti tono o te 200 kg/ha o te urea i runga i tētahi pāka 50 ha ka hiahia ki te 200 x 50 = 10,000 kg, ko te 10 tana urea. Ka hokona te nuinga o te wairākau i roto i ngā tana, na ko te huri ki ngā tana (wehea ngā kg ki te 1,000) ka ngawari ake te mahi. I te tataihanga utu, whakareatia ngā tana katoa ki te utu ia tana. Kia matua mōhio ko ngā kaiwhakaaro wairākau he whānuitanga horapa me te tawhiti haere e pa ana ki te rohe e uiui ana ia uta, na me mahi tahi me to kaita horapa, hokohoko rānei ki te whakau i ngā rahinga mahi. Ko te nuinga o ngā kamupene wairākau o Aotearoa, tae atu ki a Ballance Agri-Nutrients me Ravensdown, ka tuku tataihanga ipurangi koreutu me ngā tohutohu pūtaiao mahi māra hei āwhina i te whakamahere tono. Puna: Ballance Agri-Nutrients (ballance.co.nz); Ravensdown (ravensdown.co.nz).
He aha ngā utu wairākau o nāianei i Aotearoa?
Ka huri haere ngā utu wairākau i Aotearoa me ngā mākete rawa ao-whānui me ngā utu tohatoha-a-rohe. Hei aratohu whānui, ko ngā utu tata o te 2024 ki te 2025: urea tata ki te $700 ki te $900 ia tana; diammonium whoreputa (DAP) tata ki te $900 ki te $1,100 ia tana; superphosphate kotahi tata ki te $500 ki te $650 ia tana; puna ahuwhenua tata ki te $90 ki te $150 ia tana. Ka rereke ngā utu e ai ki te rohe, te nui mahi, me te wā o te tau. Ko ngā koopitireti wairākau matua e rua, ko Ballance Agri-Nutrients me Ravensdown, ka tuku i te nuinga o te mākete NZ, ka whakaputaina ngā rarangi utu o nāianei mō ngā kaipupuri hea. E wātea ana te hoko kake me ngā utunga nui. Me tono utu hou tonu ki to kaihoko na ka hurihia ana ngā utu. Ka taea e ngā utu waka ki te taha keehi te tāpiri i te $20 ki te $80 ia tana e ai ki te tawhiti. Puna: Ballance Agri-Nutrients (ballance.co.nz); Ravensdown (ravensdown.co.nz).
He aha te āhua o tētahi mahere wairākau NZ ahurea?
Ko te mahere wairākau paturahi ahurea o Aotearoa e hiahia ana ki te pupuri momona oneone me te whakahoki i ngā kame i tangohia e ngā kararehe me ngā hua. Mō ngā mahinga hipi me poaka paturahi, he mea noa te tono i ia tau o te superphosphate kotahi i te 150 ki te 250 kg/ha, ka tuku phosphorus me te sulphur. Ka tono pinepine urea i te koko me te koanga hei whakaohooho i te urupare nitrogen me te tipu paturahi, inā koa i runga i ngā mahinga miraka e taea ana ngā rēti nitrogen o te 100 ki te 200 kg N/ha ia tau. He nui ake te tahua wairākau whānui o ngā mahinga miraka nā te tino o te whakaputa. Ka tonoa te puna ia 3 ki te 5 tau hei pupuri i te pH oneone i waenga i te 5.8 me te 6.2. Ko te Tauākī Kaupeka Whanui mō te Whakahaere Wai Māori (NPS-FM) ka tauhere i ngā ngaro nitrogen mai i ngā mahinga i roto i ētahi manga, e pa ana ki te nui wairākau nitrogen e taea ana te tono. Me whakaaro tonu ki ngā otinga whakamatautau oneone mō ngā tono. Puna: Ballance Agri-Nutrients (ballance.co.nz); MfE (mfe.govt.nz).
He aha ngā tikanga taiao mō te whakamahi wairākau i Aotearoa?
He tipu haere te anga tikanga taiao o Aotearoa e whakahaere ana i te whakamahi wairākau, ko te aronga matua ko te whakaiti i ngā ngaro kame ki ngā awa. E ai ki te Tauākī Kaupeka Whanui mō te Whakahaere Wai Māori 2020 (NPS-FM), me tauira ngā kaunihera rohe i ngā tepe nitrogen me te phosphorus i roto i ā rātou mahere rohe. Nā reira, kua whakaritea e ngā manga awa maha ngā taupaenga ngaro nitrogen. Me mahi ngā kaipakiaka i roto i ngā manga awa whakahaere kia noho ki raro i tētahi tepe ngaro kame, ā, ka aroturuki tonu mā tētahi Mahere Taiao Mahinga (FEP) i hangaia me tētahi kaitohutohu mahinga tautohia. Hei taputapu āwhina, ka whakamahia whānuitia te tauira tahua kame Overseer i Aotearoa hei matapae i ngā ngaro kame mahinga me te arotake e tika ana. Hei tāpiri, ka taea ētahi atu tikanga i raro i ngā ture mahere-a-rohe mō te tono tata ki ngā awa, ngā tawhiti taihi, me te wā tono. Ko te urea me ngā wairākau nitrogen te nui rawa atu o te kino taiao. E akiakina ana ngā kaipakiaka kia tono anake i tā ngā whakamatautau oneone e tohu ana.

Me pēhea te mahi a tēnei tātaitai
Ka whakamahia e tēnei tātaitai ngā raraunga hou rawa mai i ngā puna kāwanatanga o Aotearoa. Ka mahia ngā tātaitai katoa ki tō pūtirotiro — kāore tō raraunga e wehe i tō pūrere.
Ka mahia ngā tātaitai katoa ki tō pūtirotiro — kāore tō raraunga e wehe i tō pūrere. Ko ngā hua hei ārahi noa iho, ehara i te tohutohu pūtea ngaio.
I hangaia, i tiakina e Konstantin Iakovlev. Raraunga mai i te IRD me ngā puna kāwanatanga mana o Aotearoa.
