Alimi aku America amagwiritsa ntchito kwambiri zida zoyezera nthaka za 7-in-1 kuti alimbikitse chitukuko cha ulimi wolondola

Ndi chitukuko chachangu cha ukadaulo wolondola wa ulimi, alimi ambiri ku United States ayamba kugwiritsa ntchito masensa a nthaka omwe amagwira ntchito zambiri kuti akonze bwino ulimi. Posachedwapa, chipangizo chotchedwa "7-in-1 soil sensor" chayambitsa chizolowezi pamsika waulimi ku US ndipo chakhala chida cha "black technology" chomwe alimi akuchifuna kugula. Sensa iyi imatha kuyang'anira nthawi imodzi zizindikiro zisanu ndi ziwiri zofunika za nthaka, kuphatikizapo chinyezi, kutentha, pH, conductivity, nayitrogeni, phosphorous ndi potaziyamu, zomwe zimapatsa alimi zambiri zokhudzana ndi thanzi la nthaka.

Wopanga sensa iyi anati chipangizochi chimagwiritsa ntchito ukadaulo wapamwamba wa Internet of Things (IoT) kuti chitumize deta ku foni yam'manja kapena kompyuta ya wogwiritsa ntchito nthawi yeniyeni. Alimi amatha kuwona momwe nthaka ilili pogwiritsa ntchito njira zomwe zili pansipa ndikusintha feteleza, kuthirira ndi mapulani obzala kutengera detayo. Mwachitsanzo, sensa ikazindikira kuti nayitrogeni m'nthaka sikokwanira, dongosololi lidzakumbutsa wogwiritsa ntchitoyo kuti awonjezere feteleza wa nayitrogeni, potero kupewa vuto la feteleza wochulukirapo kapena michere yosakwanira.

Dipatimenti ya Zaulimi ku US (USDA) ikuthandiza kukweza ukadaulo uwu. Mneneri wina anati: “Choyezera nthaka cha 7-in-1 ndi chida chofunikira kwambiri pa ulimi wolondola. Sichingathandize alimi kuwonjezera zokolola zokha, komanso kuchepetsa kuwononga zinthu zachilengedwe komanso kuchepetsa kuwonongeka kwa chilengedwe.” M'zaka zaposachedwa, Dipatimenti ya Zaulimi ku US yakhala ikulimbikitsa zatsopano mu ukadaulo waulimi kuti ichepetse kugwiritsa ntchito feteleza ndi madzi pomwe ikukweza zokolola ndi ubwino wa mbewu.

John Smith, mlimi wochokera ku Iowa, ndi m'modzi mwa ogwiritsa ntchito koyamba sensa iyi. Iye anati: "M'mbuyomu, tinkangoweruza momwe nthaka ilili potengera zomwe takumana nazo. Tsopano ndi deta iyi, zisankho zobzala zakhala zasayansi kwambiri. Chaka chatha, zokolola zanga za chimanga zidakwera ndi 15%, ndipo kugwiritsa ntchito feteleza kudatsika ndi 20%.

Kuwonjezera pa kupititsa patsogolo ntchito yopangira, sensa ya nthaka ya 7-in-1 imagwiritsidwanso ntchito kwambiri pofufuza. Magulu ofufuza zaulimi m'mayunivesite ambiri ku United States akugwiritsa ntchito zipangizozi pofufuza zaumoyo wa nthaka kuti apange njira zokhazikika zaulimi. Mwachitsanzo, ofufuza ku University of California, Davis akusanthula deta ya sensa kuti afufuze momwe angagwiritsire ntchito bwino madzi m'madera omwe ali ndi chilala.

Ngakhale mtengo wa sensa iyi ndi wokwera pang'ono, ubwino wake wa nthawi yayitali ukukopa alimi ambiri. Malinga ndi ziwerengero, malonda a sensa ku Midwest ku United States awonjezeka ndi pafupifupi 40% chaka chatha. Opanga akukonzekeranso kuyambitsa ntchito zobwereka kuti achepetse malire a minda yaying'ono.

Akatswiri akukhulupirira kuti chifukwa cha kufalikira kwa ukadaulo wa ulimi wolondola, zipangizo zanzeru monga choyezera nthaka cha 7-in-1 zidzakhala muyezo wa ulimi wamtsogolo. Izi sizingothandiza kuthana ndi mavuto apadziko lonse lapansi okhudzana ndi chitetezo cha chakudya, komanso zimalimbikitsa ulimi kuti ukhale wochezeka komanso wotetezeka.
