Pankhani yopanga ulimi ndi kafukufuku wa sayansi, kumvetsetsa bwino momwe nthaka ilili n'kofunika kwambiri. Chojambulira nthaka 8 mwa 1, chomwe chikuyamba kugwiritsidwa ntchito masiku ano, chakhala dzanja lamanja la akatswiri ambiri chifukwa cha ntchito zake zamphamvu.
Chida chowonjezera kupanga m'mafamu akuluakulu
Mu famu yayikulu yolima chakudya ku Australia, zokolola zakhala zovuta kale podalira luso la ntchito zaulimi. Izi zasintha kwambiri ndi kuyambitsa sensa ya nthaka 8 mu 1. Sensa iyi ili ndi kulondola kwakukulu, imatha kukhala yolondola kwambiri nthawi imodzi kuti iwunikire pH ya nthaka, nayitrogeni, phosphorous ndi potaziyamu, chinyezi, kutentha ndi zizindikiro zina zisanu ndi zitatu zofunika, kuti ipereke chithandizo chodalirika cha deta kwa alimi. Kukhazikika kwake ndi kwabwino kwambiri, ndipo sipadzakhala kusiyana kwa deta chifukwa cha kusinthasintha pang'ono kwa chilengedwe, komwe kumatsimikizira kutulutsa deta kokhazikika kwa nthawi yayitali. Kuphatikiza apo, ndikosavuta kuyiyika, popanda zida zovuta zaukadaulo komanso njira yayitali yogwirira ntchito, ogwira ntchito pafamu amatha kumaliza kuyika mosavuta.
Kutengera ndi deta ya mayankho a sensa, mlimi akhoza kusintha bwino ndondomeko ya feteleza. Sensa ikawonetsa kusowa kwa nayitrogeni m'nthaka, ndi deta yake yolondola, mlimi akhoza kuwonjezera feteleza wa nayitrogeni munthawi yake komanso yoyenera, kupewa zinyalala ndi kuipitsidwa kwa nthaka komwe kumachitika chifukwa cha feteleza wosawona. Ponena za kuthirira, sensa ya nthaka 8 mu 1 nthawi yeniyeni imapereka deta ya chinyezi cha nthaka, kuti alimi athe kukonza nthawi yothirira ndi madzi moyenera, kuti awonetsetse kuti mbewu nthawi zonse zimakhala pamalo abwino kwambiri okulira. Pakapita chaka, kupanga chakudya cha famu kwawonjezeka ndi 25%, koma mtengo wake watsika ndi 15%, ndipo sensa ya nthaka 8 mu 1 yakhala chinsinsi chowonjezera ndalama za famu.
Bwenzi lachikondi la okonda ulimi wa m'mizinda
M'minda ya m'mizinda yokhala ndi denga la nyumba ndi minda yaying'ono yamaluwa, malo ndi ochepa, ndipo nthaka imakhala yovuta kwambiri. Bambo Lee, wokonda minda, wayika choyezera nthaka 8 mu 1 m'munda wake wa padenga. Ndi chaching'ono, chosavuta kuyika, koma champhamvu. Amatha kuwona zizindikiro za nthaka nthawi yomweyo kuchokera pafoni yake yam'manja. Akabzala maluwa, zoyezera zikazindikira kuti pH ya nthaka siyoyenera kukula kwa maluwa, nthawi yomweyo amakonza nthaka kuti atsimikizire kuti maluwawo akula bwino. Ndi choyezera nthaka 8 mu 1, mundawo uli wodzaza ndi maluwa ndi zipatso, ndipo anansi amamuchitira nsanje ndipo amamufunsa upangiri.
Thandizo lolondola la mapulojekiti ofufuza asayansi
Pulojekiti yofufuza zaulimi ku yunivesite ku India inafunika kufufuza mozama za kukula kwa mbewu m'malo osiyanasiyana a nthaka. Chowunikira nthaka 8 pa 1 chimagwira ntchito yofunika kwambiri. Kudzera mu izi, ofufuza apeza zambiri zolondola za nthaka, zomwe zimapereka chithandizo champhamvu pophunzira momwe mbewu zimasinthira ku mikhalidwe yosiyanasiyana ya nthaka. Mwachitsanzo, pofufuza mtundu watsopano wa mbewu, malinga ndi deta ya chowunikira, ofufuza adapeza kuti mtunduwo pansi pa kutentha ndi chinyezi cha nthaka, kukula kwa mizu kumakhala bwino, motero kupereka maziko asayansi owongolera dongosolo lobzala, ndikulimbikitsa kupita patsogolo bwino kwa polojekiti yofufuza zasayansi.
Kaya ndi ulimi waukulu, kubzala mitengo m'minda yaying'ono, kapena mapulojekiti ofufuza asayansi ovuta, choyezera nthaka 8 mwa 1 chingathandize kwambiri chifukwa cha luso lake lowunikira bwino komanso molondola. Ngati mukuda nkhawa ndi kuyang'anira ndi kusamalira momwe nthaka ilili, yesani choyezera nthaka chodabwitsa ichi 8 mwa 1 kuti muyambe ulendo wobzala komanso wofufuza bwino komanso wasayansi.
Ngati muli ndi vuto lililonse,
chonde funsani mainjiniya athu, Marvin.
