Nthawi Yatsopano Yothirira Mwanzeru: Momwe Ma Sensor a Nthaka Amayang'anira Molondola Kuchuluka kwa Ulimi, Kuthandiza Kusunga Madzi ndi Kuonjezera Mphamvu

Alimi kale ankadalira nyengo ndi luso lawo pa ulimi wothirira. Tsopano, ndi chitukuko cha intaneti ya zinthu ndi ukadaulo wanzeru wa ulimi, masensa a nthaka akusintha pang'onopang'ono njira yachikhalidweyi. Mwa kuyang'anira chinyezi cha nthaka molondola, amapereka chithandizo cha deta yeniyeni yothirira mwasayansi, zomwe zimayambitsa nthawi ya ulimi wothandiza komanso wosunga madzi.

M'minda ikuluikulu, zoyezera nthaka zomwe zili mkati mwa mizu ya mbewu zimagwira ntchito ngati "zosavuta kumva"mapeto a mitsempha,” kupitiriza kugwira nthaka “kugunda kwa mtima"Maola 24 pa sabata. Masensawa samangoyang'anira kuchuluka kwa chinyezi chofunikira komanso amapereka kusanthula kwakuya kwa kapangidwe ka nthaka, pH, mchere, ndi kuchuluka kwa michere yosiyanasiyana (monga nayitrogeni, phosphorous, ndi potaziyamu).

“Kale, nthawi zonse ndinkada nkhawa ndi kuthirira madzi mopitirira muyeso kapena mopitirira muyeso. Tsopano, pulogalamu yam'manja imandithandiza kuona kusowa kwa madzi pamunda uliwonse, zomwe zimakhala zosavuta kuzimvetsa,” anatero mlimi wina amene amagwiritsa ntchito ukadaulo uwu. “Izi sizingopulumutsa madzi okwana 30% okha, komanso chofunika kwambiri, zimateteza kutayika kwa michere ndi kuwonongeka kwa kapangidwe ka nthaka komwe kumachitika chifukwa cha kuthirira mopitirira muyeso.”

Akatswiri amanena kuti kufunika kwa zoyezera nthaka kumapitirira malire a kusunga madzi. Kusamalira bwino chinyezi ndi michere ya nthaka kungathandize kuti mizu ya mbewu ikule bwino komanso kukonza kapangidwe ka nthaka. M'kupita kwa nthawi, ndi njira yothandiza yolimbana ndi kukokoloka ndi kuwonongeka kwa nthaka. Kuphatikiza apo, kumvetsetsa pH ya nthaka ndikofunikira kwambiri posintha njira zothirira feteleza ndikukonza malo okhala nthaka.

"Deta yomwe timasonkhanitsa idzatithandiza kupanga database yokwanira yogawa nthaka,"anafotokoza wasayansi wa zaulimi. "Izi sizingotsogolera njira zaulimi zomwe zilipo pano komanso zipereka maziko asayansi okonzanso nthaka mtsogolo komanso kasamalidwe ka nthaka kokhazikika."

Ndi kuchepa kwa ndalama komanso kukonza luso losanthula deta, masensa a nthaka, omwe kale ankaganiziridwa kuti “ukadaulo wakuda"," zikufalikira mofulumira. Zikusonyeza kusintha kwa ulimi kuchoka pa kayendetsedwe kake kupita ku kupanga zisankho zenizeni, kuonetsetsa kuti chakudya chili bwino komanso kuteteza nthaka yamtengo wapatali yomwe timadalira.
