Alimi aku America amatenga kwambiri masensa 7-mu-1 kuti alimbikitse ulimi wolondola

Chifukwa chakukula mwachangu kwaukadaulo waulimi wolondola, alimi ochulukirachulukira ku United States ayamba kugwiritsa ntchito zida zowunikira nthaka kuti azilima bwino. Posachedwapa, chipangizo chotchedwa "7-in-1 soil sensor" chayambitsa chisokonezo pamsika waulimi ku US ndipo chakhala chida cha "teknoloji yakuda" chomwe alimi akuthamangira kugula. Kachipangizo kameneka kamatha kuyang'anira nthawi imodzi zizindikiro zazikulu zisanu ndi ziwiri za nthaka, kuphatikizapo chinyezi, kutentha, pH, conductivity, nitrogen content, phosphorous ndi potaziyamu, zomwe zimapatsa alimi chidziwitso chokwanira cha thanzi la nthaka.

Wopanga sensayi ananena kuti chipangizochi chimagwiritsa ntchito ukadaulo wapamwamba wa intaneti wa Zinthu (IoT) kutumiza zidziwitso ku foni yam'manja ya wogwiritsa ntchito kapena kompyuta munthawi yeniyeni. Alimi atha kuwona momwe nthaka ikuyendera ndikuyika feteleza, ulimi wothirira ndi kubzala motengera zomwe zalembedwa. Mwachitsanzo, sensa ikazindikira kuti nayitrogeni m’nthaka ndi yosakwanira, dongosololi lidzangokumbutsa wogwiritsa ntchito kuti awonjezere feteleza wa nayitrogeni, potero kupeŵa vuto la kuthira feteleza kwambiri kapena kusakwanira kwa michere.

Dipatimenti ya zaulimi ku US (USDA) imathandizira kupititsa patsogolo lusoli. Mneneri wina ananena kuti: “Sensa ya nthaka ya 7-in-1 ndi chida chofunika kwambiri pa ulimi wolondola, osati kungothandiza alimi kuwonjezera zokolola, komanso kuchepetsa kuwonongeka kwa zinthu ndi kuchepetsa kuwonongeka kwa chilengedwe.” M’zaka zaposachedwapa, Dipatimenti ya Zaulimi ku United States yakhala ikulimbikitsa luso laumisiri waulimi kuti achepetse kugwiritsa ntchito feteleza ndi madzi kwinaku akukonza zokolola komanso zokolola bwino.

John Smith, mlimi wochokera ku Iowa, ndi m'modzi mwa ogwiritsa ntchito sensayi. Iye anati: "M'mbuyomu, tinkangoweruza nthaka pogwiritsa ntchito zomwe takumana nazo." Tsopano ndi deta iyi, zosankha zobzala zakhala zasayansi kwambiri. Chaka chatha, zokolola zanga za chimanga zinawonjezeka ndi 15%, ndipo kugwiritsa ntchito feteleza kunatsika ndi 20%.

Kuphatikiza pakuwongolera magwiridwe antchito, 7-in-1 sensa ya nthaka imagwiritsidwanso ntchito kwambiri pakufufuza. Magulu ofufuza zaulimi m'mayunivesite ambiri ku United States akugwiritsa ntchito zidazi pochita kafukufuku waumoyo wanthaka kuti apange njira zokhazikika zaulimi. Mwachitsanzo, ofufuza a ku yunivesite ya California, Davis akusanthula deta ya sensa kuti afufuze momwe angagwiritsire ntchito bwino madzi m'madera omwe akukhudzidwa ndi chilala.

Ngakhale mtengo wa sensayi ndi wokwera kwambiri, ubwino wake wautali umakopa alimi ambiri. Malinga ndi ziwerengero, kugulitsa ma sensor ku Midwest ku United States kwakwera pafupifupi 40% mchaka chatha. Opanga akukonzekeranso kuyambitsa ntchito zobwereketsa kuti achepetse malire a mafamu ang'onoang'ono.

Ofufuza akukhulupirira kuti ndi kutchuka kwaukadaulo waulimi wolondola, zida zanzeru monga 7-in-1 sensa ya nthaka zidzakhala muyezo waulimi wamtsogolo. Izi sizidzangothandiza kuthana ndi zovuta zachitetezo cha chakudya padziko lonse lapansi, komanso kulimbikitsa ulimi kuti ukhale wowongolera zachilengedwe komanso wokhazikika.
