Ma sensor nthaka anzeru amatha kuchepetsa kuwonongeka kwa chilengedwe kuchokera ku feteleza

Bizinesi yaulimi ndi malo oyambilira asayansi ndiukadaulo.Mafamu amakono ndi ntchito zina zaulimi n’zosiyana kwambiri ndi zakale.
Akatswiri pamakampaniwa nthawi zambiri amakhala okonzeka kugwiritsa ntchito matekinoloje atsopano pazifukwa zosiyanasiyana.Zipangizo zamakono zingathandize kuti ntchito ziziyenda bwino, zomwe zimathandiza alimi kuchita zambiri pakapita nthawi yochepa.
Pamene chiŵerengero cha anthu chikukula, kupangidwa kwa chakudya kukuwonjezereka, zonse zimadalira pa feteleza wa mankhwala.
Cholinga chachikulu ndi chakuti 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 chimawonjezedwa m'nthaka kuti chilimbikitse kukula kwa mbewu ndipo chakhala gawo lofunika kwambiri pazaulimi, makamaka pakutukuka kwa mafakitale.Pali mitundu yambiri ya feteleza, kuphatikizapo mchere, organic ndi mafakitale feteleza.Zambiri zimakhala ndi zinthu zitatu zofunika: nayitrogeni, phosphorous ndi potaziyamu.
Tsoka ilo, si nayitrogeni yonse yomwe imafika ku mbewu zokha.M'malo mwake, 50% yokha ya nayitrogeni mu feteleza imagwiritsidwa ntchito ndi zomera paminda.
Kutayika kwa nayitrojeni ndi vuto la chilengedwe pamene limalowa mumlengalenga ndi matupi amadzi monga nyanja, mitsinje, mitsinje ndi nyanja.Ndizoyeneranso kudziwa kuti muulimi wamakono, feteleza wa nayitrogeni amagwiritsidwa ntchito nthawi zambiri.
Tizilombo tating'onoting'ono tanthaka titha kusintha nayitrojeni kukhala mpweya wina wokhala ndi nayitrogeni wotchedwa greenhouse gases (GHGs).Kuchulukirachulukira kwa mpweya wowonjezera kutentha mumlengalenga kumabweretsa kutentha kwa dziko, ndipo, pamapeto pake, kusintha kwanyengo.Komanso, nitrous oxide (wowonjezera kutentha mpweya) ndi wothandiza kwambiri kuposa mpweya woipa.
Zinthu zonsezi zimatha kusokoneza chilengedwe.Feteleza wokhala ndi nayitrogeni ndi lupanga lakuthwa konsekonse: ndi ofunikira pakukula kwa mbewu, koma nayitrogeni wochulukirapo amatha kutulutsidwa mumlengalenga ndikuyambitsa zovuta zingapo pa moyo wa anthu ndi nyama.
Pamene ogula ambiri akukhala ndi moyo wobiriwira, makampani m'mafakitale onse akuyang'ana kuti agwiritse ntchito njira zokhazikika kuti athe kusintha chilengedwe.
Alimi azitha kuchepetsa kuchuluka kwa feteleza wamankhwala omwe amagwiritsidwa ntchito polima mbewu popanda kusokoneza zokolola.
Olima amatha kusintha njira zawo zoberekera potengera zosowa zenizeni za mbewu zawo komanso zotsatira zomwe akufuna kukwaniritsa.
