Zoseweretsa zanzeru za nthaka zitha kuchepetsa kuwonongeka kwa chilengedwe chifukwa cha feteleza

Makampani a ulimi ndi malo ophunzirira zatsopano za sayansi ndi ukadaulo. Mafamu amakono ndi ntchito zina zaulimi ndi zosiyana kwambiri ndi zakale.
Akatswiri mumakampani amenewa nthawi zambiri amakhala okonzeka kugwiritsa ntchito ukadaulo watsopano pazifukwa zosiyanasiyana. Ukadaulo ungathandize kuti ntchito ziyende bwino, zomwe zimathandiza alimi kuchita zambiri munthawi yochepa.
Pamene chiwerengero cha anthu chikukula, kupanga chakudya kukupitirirabe kukwera, zomwe zonse zimadalira feteleza wa mankhwala.
Cholinga chachikulu ndichakuti alimi achepetse kuchuluka kwa feteleza omwe amagwiritsa ntchito pamene akuchulukitsa zokolola.
Kumbukirani kuti zomera zina zimafuna feteleza wambiri, monga tirigu.

Feteleza ndi chinthu chilichonse chomwe chimawonjezeredwa kunthaka kuti chilimbikitse kukula kwa zomera ndipo chakhala gawo lofunika kwambiri pa ulimi, makamaka ndi mafakitale. Pali mitundu yambiri ya feteleza, kuphatikizapo feteleza wa mchere, wachilengedwe ndi wa mafakitale. Ambiri ali ndi michere itatu yofunika: nayitrogeni, phosphorous ndi potaziyamu.
Mwatsoka, si nayitrogeni yonse yomwe imafika pa mbewu zokha. Ndipotu, 50% yokha ya nayitrogeni yomwe ili mu feteleza imagwiritsidwa ntchito ndi zomera m'minda.
Kutayika kwa nayitrogeni ndi vuto la chilengedwe pamene limalowa mumlengalenga ndi m'madzi monga nyanja, mitsinje, mitsinje ndi nyanja. Ndikofunikiranso kudziwa kuti mu ulimi wamakono, feteleza wa nayitrogeni amagwiritsidwa ntchito kwambiri.
Tizilombo tina ta m'nthaka tingasinthe nayitrogeni kukhala mpweya wina wokhala ndi nayitrogeni wotchedwa mpweya wowonjezera kutentha (GHGs). Kuwonjezeka kwa mpweya wowonjezera kutentha womwe umachokera mumlengalenga kumabweretsa kutentha kwa dziko lapansi, ndipo pamapeto pake, kusintha kwa nyengo. Kuphatikiza apo, nitrous oxide (mpweya wowonjezera kutentha) ndi wothandiza kwambiri kuposa carbon dioxide.
Zinthu zonsezi zitha kuwononga chilengedwe. Manyowa okhala ndi nayitrogeni ndi lupanga lakuthwa konsekonse: ndi ofunikira pakukula kwa zomera, koma nayitrogeni wochuluka amatha kutulutsidwa mumlengalenga ndikuyambitsa mavuto ambiri pa moyo wa anthu ndi nyama.
Pamene ogula ambiri akuyamba kugwiritsa ntchito njira zosamalira chilengedwe, makampani m'mafakitale onse akuyang'ana kugwiritsa ntchito njira zokhazikika kuti athandize chilengedwe.
Alimi adzatha kuchepetsa kuchuluka kwa feteleza wa mankhwala omwe amagwiritsidwa ntchito popanga mbewu popanda kusokoneza zokolola.
Alimi amatha kusintha njira zawo zobereketsera mbewu kutengera zosowa za mbewu zawo komanso zotsatira zomwe akufuna kupeza.
