Kuyang'anira deta ya nthaka nthawi yeniyeni komanso kukonza bwino ulimi wothirira ndi feteleza kukuyambitsa kusintha kwanzeru kwa ulimi kwa alimi aku Brazil.
Chifukwa cha kupita patsogolo mwachangu kwa sayansi ndi ukadaulo waulimi padziko lonse lapansi, Brazil, monga dziko lalikulu laulimi padziko lonse lapansi, ikulandira mwachangu ukadaulo waulimi wolondola. Ma sensor anzeru a nthaka ochokera ku China alowa mumsika waku Brazil, akupereka njira zowunikira nthaka nthawi yeniyeni kwa alimi am'deralo, mabungwe ogwirizana ndi ulimi ndi mabungwe ofufuza. Izi zimathandiza kuwonjezera zokolola, kuchepetsa kuwononga zinthu komanso kulimbikitsa chitukuko chokhazikika chaulimi.
Zovuta ndi Mwayi wa Ulimi wa ku Brazil
Dziko la Brazil ndi limodzi mwa mayiko omwe amapanga soya, khofi ndi nzimbe kwambiri padziko lonse lapansi, koma ulimi wake ukukumana ndi mavuto ambiri:
Kutayika kwa michere m'nthaka: Nyengo yotentha imabweretsa mvula pafupipafupi, kuwonjezereka kwa kutayika kwa michere m'nthaka, ndipo kubzala mbewu pogwiritsa ntchito njira zachikhalidwe n'kovuta kulamulira bwino.
Chilala ndi Kugwiritsa Ntchito Bwino kwa Madzi Othirira: M'madera ena (monga kumpoto chakum'mawa), vuto la chilala ndi lalikulu, ndipo kasamalidwe ka madzi kumakhala kofunikira kwambiri.
Mtengo wa feteleza wa mankhwala ukukwera: Ufewetse wochuluka umawonjezera ndalama ndipo ungawononge chilengedwe.
Zipangizo zoyezera nthaka zopangidwa ku China (zowunikira chinyezi, kutentha, pH, michere ya NPK, ndi zina zotero) zimatha kutumiza deta nthawi yomweyo ku mafoni am'manja kapena makompyuta kudzera muukadaulo wa Internet of Things (IoT), kuthandiza alimi.
✅ Kuthirira moyenera: Kumasintha kuchuluka kwa madzi kokha kutengera chinyezi cha nthaka, ndikusunga madzi okwana 30%.
✅ Ufewetsi wa sayansi: Onjezerani nayitrogeni, phosphorous ndi potaziyamu ngati pakufunika kuti muchepetse mtengo wa feteleza wa mankhwala ndi zoposa 20%.
✅ Chenjezo la tsoka: Yang'anirani kuchuluka kwa mchere m'nthaka kapena kuchuluka kwa asidi ndipo thandizani pasadakhale.
Nkhani Yopambana: Ndemanga Zenizeni Zochokera kwa Alimi aku Brazil
Nkhani 1: Malo Olima Khofi ku Sao Paulo
Vuto: Kulima khofi mwachikhalidwe kumabweretsa kusakhazikika kwa khalidwe la nyemba za khofi.
Yankho: Gwiritsani ntchito masensa a nthaka okhala ndi magawo ambiri opangidwa ku China kuti aziwunika pH ndi EC nthawi yeniyeni.
Zotsatira: Kupanga khofi kunakwera ndi 15%, ndipo chiwerengero cha nyemba zabwino kwambiri chinakwera kwambiri.
Nkhani 2: Famu ya Soya ya Mato Grosso
Vuto: Madzi othirira amakhala ochepa nthawi yachilimwe.
Yankho: Ikani netiweki yopanda zingwe yonyowetsa nthaka ndikulumikiza njira yothirira.
Zotsatira: Kusunga madzi 25%, zokolola za soya pa gawo lililonse la gawo zinawonjezeka ndi 10%.
Bwanji kusankha zoyezera nthaka zaku China?
Kugwira ntchito mokwera mtengo: Poyerekeza ndi mitundu yaku Europe ndi America, masensa aku China ali ndi mtengo wopikisana kwambiri ndipo amagwira ntchito bwino.
Yolimba komanso yosinthika: Yopangidwira nyengo zotentha, ndi yosalowa madzi komanso yosagwira dzimbiri, yoyenera malo obiriwira ku Brazil.
Thandizani maoda ang'onoang'ono oyesera: Perekani zitsanzo za ntchito kuti muchepetse zoopsa zogulira.
Malingaliro a Akatswiri
Carlos Silva, Wofufuza wa Bungwe la Brazilian Association of Agricultural Science and Technology (ABAG):
Zipangizo zoyezera nthaka zanzeru ndi zida zofunika kwambiri pakusintha kwa digito kwa ulimi ku Brazil. Kuchulukana mwachangu komanso phindu la ukadaulo waku China zikufulumizitsa kufalikira ndi kugwiritsidwa ntchito pakati pa alimi ang'onoang'ono ndi apakatikati.
Zambiri zaife
HONDE ndi kampani yogulitsa zinthu zoyezera ulimi zanzeru, yodzipereka pa kafukufuku ndi chitukuko cha zinthu zoyezera ulimi kwa zaka 10. Zogulitsa zake zatumizidwa kumayiko opitilira 30 padziko lonse lapansi, kuphatikizapo misika yayikulu yaulimi ku South America monga Brazil ndi Argentina.
