Chiyeso chobisika chofunikira pa dziko lathu lapansi: chinyezi cha nthaka
Mlimi akukonzekera nyengo yotsatira yothirira, katswiri wa zamadzi akulosera za kuopsa kwa kusefukira kwa madzi pambuyo pa mvula yamphamvu, kapena wasayansi wa nzika yemwe akuyang'anira ubwino wa zachilengedwe zapafupi onse ali ndi chinthu chimodzi chobisika chofanana: kuchuluka kwa madzi m'nthaka. Pansi pa mapazi athu, muyeso wofunikira uwu wa chilengedwe umakhudza kwambiri ulimi, zamadzi, ndi zachilengedwe. Komabe, kwa zaka zambiri, mwayi wopeza chidziwitso chodalirika cha chinyezi cha nthaka unali wochepa. Njira yolondola kwambiri yachikhalidwe, njira ya gravimetric, ndi yofunikira kwambiri ndipo siiyenera kuyesedwa mwachangu. Masensa amakono amalonda amapereka yankho koma ndi okwera mtengo kwambiri kwa anthu ambiri. Pofuna kuthana ndi mavutowa, ofufuza adapanga Sensor Yotsika Mtengo ya Soil, yomwe ndi chipangizo chosinthika chomwe chimapangitsa kuti aliyense athe kupeza ziwerengero zolondola komanso zamakono za chinyezi cha nthaka.
Kumanani ndi Soil Sensor, chida cha alimi ndi asayansi nzika.
Chojambulira nthaka chinapangidwa makamaka ndi cholinga chimodzi: kupatsa alimi ndi anthu ena chida chotsika mtengo, champhamvu, komanso chosavuta kugwiritsa ntchito chomwe chingayese kuchuluka kwa madzi omwe ali mkati mwa nthaka akamagwira ntchito panja. Chapangidwa poganizira alimi kuti athe kuchita ulimi wolondola pogwiritsa ntchito izi komanso anthu wamba omwe amakonda chilengedwe angathandize kuyang'anira mbali zazikulu za chilengedwe chathu pamodzi. Chipangizochi ndi chaching'ono, chopepuka komanso chosavuta kugwiritsa ntchito m'munda.
Zinthu zofunika kwambiri: Mphamvu zili m'manja mwanu, Kuphweka kuli m'manja.
Soil Sensor ili ndi luso lapamwamba mu phukusi lotsika mtengo. Linapangidwa kuti likhale lolondola, losavuta kugwiritsa ntchito, komanso lotsika mtengo.
Kulondola kotsimikizika: Poyesa nthaka ya mchere monga loam ndi sand loam, sensa ya nthaka yawonetsa kulondola kofanana ndi masensa okwera mtengo komanso otchuka amalonda monga HydraProbe ndi ThetaProbe. Mayeso akuwonetsa kulumikizana kwamphamvu ndi zida zomwe zadziwika kale. Imagwira ntchito bwino kwambiri mu dothi la mchere, koma ziyenera kudziwika kuti, mofanana ndi masensa ena a dielectric, ili ndi kulondola kochepa mu dothi la m'nkhalango lachilengedwe kwambiri, zomwe asayansi akugwirabe ntchito.
Kulumikizana Mwanzeru: Sensa imalumikizana mosavuta ndi Bluetooth/WIFI ku pulogalamu yam'manja yosavuta kugwiritsa ntchito yomwe imagwira ntchito pazida zonse za Android ndi iOS.
Pulogalamu yamphamvu yam'manja: Pulogalamu ya Companion imapereka njira yonse yoyendetsera deta. Mutha kuwona manambala enieni a VWC a nthaka nthawi yomweyo, kusankha pakati pa kuwerengera kwa nthaka wamba kapena yeniyeni kuti zinthu zikhale zolondola, kusunga nambala iliyonse ndi komwe idatengedwa (latitude ndi longitude), ndikutumiza manambala anu onse ku mafayilo a .txt kapena .csv kuti muwawonenso mtsogolo.
Cholimba komanso Chokonzeka Kumunda: Chipangizochi chapangidwa kuti chigwiritsidwe ntchito m'munda. Ndi chaching'ono, chopepuka ndipo chili ndi kapangidwe kosavuta komwe kamalola anthu kukonza zinthu zomwe angapeze mosavuta. Buku lofotokozera mwatsatanetsatane limaphatikizapo njira zonse zosamalira.
Kodi zingatheke bwanji kukhala zolondola chonchi?
Sensa ya nthaka ndi sensa yochokera ku dielectric permittivity yomwe imagwira ntchito pogwiritsa ntchito njira ya TLO. Imagwiritsa ntchito njira yotsimikiziridwa mwasayansi yotumizira mafunde amagetsi otsika pafupipafupi pansi kudzera muzitsulo zake. Kenako imabwezeretsa mafundewo ndikuyang'ana kuchuluka kwa madzi omwe abwerera. Izi zimatengera kuchuluka kwa madzi omwe alipo. Izi zimachitika chifukwa chakuti madzi ali ndi dielectric constant yapamwamba kwambiri kuposa mchere wouma wa nthaka. Tangoganizirani kuponya mpira m'nthaka. Dothi louma silipereka mphamvu zambiri, koma madzi amagwira ntchito ngati matope okhuthala omwe amachedwetsa mpirawo kwambiri. Kuyeza kuchuluka kwa "mpira" womwe ukuchedwetsedwa ndikuwonetsedwa ndi sensa kumalola kuwerengera molondola kuchuluka kwa "matope", kapena madzi, omwe ali m'nthaka.
Zatsimikiziridwa m'munda: kuyambira m'mafamu aku yunivesite mpaka ku kampeni za NASA.
Pofuna kutsimikiza kuti ndi yodalirika komanso yodalirika, choyezera nthaka chinadutsa mu mayeso ovuta komanso mayeso ambiri m'mikhalidwe yosiyanasiyana yeniyeni.
Kuyesa kwakukulu kunachitika ndi zitsanzo za nthaka 408 zomwe zinatengedwa m'malo 83, zogawidwa m'madontho 70 a nthaka yamchere (zitsanzo 301) ndi madontho 13 a nthaka yachilengedwe (zitsanzo 107). Zinaphatikizapo mitundu yambiri ya minda ndi nkhalango.
Mayeso a Zaulimi: Sensayi idayesedwa m'mafamu ofufuza zaulimi ku Michigan State University (MSU) komwe idagwiritsidwa ntchito poyang'anira chinyezi cha nthaka m'minda yokhala ndi mbewu monga soya ndi chimanga.
Nkhani zogwiritsira ntchito: Kutulutsa mphamvu ya deta ya nthaka
Choyezera nthaka chimapatsa anthu ambiri mwayi wodziwa bwino kuchuluka kwa madzi omwe ali m'nthaka kuti athe kusankha bwino.
Za Ulimi Wolondola
Alimi amapeza chidziwitso chomwe amafunikira m'minda yawo pogwiritsa ntchito choyezera nthaka ichi popanda kugwiritsa ntchito ndalama zambiri. Chida ichi chimakupatsani mwayi wosankha mwanzeru nthawi yanu yothirira komanso kudziwa bwino momwe mbewu zanu zimafunikira madzi, zomwe zimapangitsa kuti zokolola ziwonjezeke komanso kuti zigwire bwino ntchito komanso zimachepetsa kutaya madzi ndi michere yomwe imalowa m'madzi.
Za Sayansi ya Nzika
Masensa a nthaka ndi zida zabwino kwambiri pamapulojekiti a sayansi ya nzika monga pulogalamu ya NASA ya GLOBE. Ndi yotsika mtengo komanso yosavuta kugwiritsa ntchito, zomwe zimathandiza odzipereka ammudzi, ophunzira, ndi aphunzitsi kutenga nawo mbali pazinthu zazikulu zosonkhanitsira deta. Ntchitoyi imawonjezera ku deta yolimba yomwe ikufunika kuti ilinganize ndikutsimikizira zinthu zonyowa za nthaka zochokera ku satelayiti, monga zomwe zachokera ku ntchito ya NASA ya SMAP.
Kafukufuku ndi kuyang'anira zachilengedwe
Kwa ofufuza, imapereka njira yotsika mtengo yopezera deta yabwino. Ingagwiritsidwe ntchito pa kafukufuku wokhudza ubale wa mvula ndi madzi, njira zachilengedwe m'malo ouma, komanso kupanga njira zogwiritsira ntchito nthaka moyenera. Komanso, bolodi lamkati la sensa lili ndi madoko omwe amalola masensa ena a nyengo kulumikizidwa, zomwe zimapangitsa kuti ikhale yothandiza poyang'anira chilengedwe chonse.
Pomaliza: Deta yolondola ya chinyezi cha nthaka tsopano ikupezeka.
Chojambulira Madzi a Dothi Chotsika Mtengo chimagwirizanitsa bwino mfundo zolondola komanso zotsika mtengo. Kuphatikiza mtengo wotsika pansi pa $100 ndi magwiridwe antchito ofanana ndi mitundu yokwera mtengo yamalonda komanso mawonekedwe osavuta kugwiritsa ntchito kumapangitsa chipangizochi kukhala chosavuta kugwiritsa ntchito kwa aliyense kukhala ndi chimodzi mwa zizindikiro zofunika kwambiri zachilengedwe padziko lonse lapansi. Chojambulira cha nthaka sichimangoyesa chinyezi cha dziko lapansi, koma chimapatsa gulu latsopano la anthu mphamvu yosamalira nthaka, kuwapatsa chidziwitso chofunikira chokhudza chilengedwe kuti athe kuthandiza kupanga dziko lapansi kukhala lolimba komanso labwino kwa aliyense, gawo limodzi la minda, mtsinje, ndi nkhalango nthawi imodzi.
Kuti mudziwe zambiri zokhudza sensa ya nthaka,
