Zida zowotchera manyowa a nkhumba
Zida zowotchera manyowa a nkhumba zimagwiritsidwa ntchito potembenuza manyowa a nkhumba kukhala feteleza wa organic kudzera mu fermentation.Zipangizozi zimapangidwira kuti zikhale ndi malo omwe amalimbikitsa kukula kwa tizilombo tothandiza tomwe timaphwanya manyowa ndi kuwasintha kukhala feteleza wochuluka wa michere.
Mitundu yayikulu ya zida zoyatsira feteleza wa nkhumba ndi:
1. Dongosolo la kompositi m'ziwiya: M'dongosolo lino, manyowa a nkhumba amayikidwa mu chotengera chotsekedwa, chomwe chimakhala ndi njira zowongolera mpweya komanso kutentha.Manyowa amatembenuzidwa nthawi ndi nthawi kuti awonetsetse kuti mbali zonse za zinthuzo zimawonekera mumlengalenga ndi kutentha, kulimbikitsa kukula kwa tizilombo tothandiza.
2. Dongosolo la kompositi ya Windrow: Dongosololi limakhudza kuyika manyowa a nkhumba mumilu yayitali, yopapatiza kapena mizere yotchedwa ma windrows.Mawindo amatembenuzidwira nthawi zonse kuti alimbikitse mpweya komanso kuonetsetsa kuti mbali zonse za zinthuzo zimakhala ndi mpweya ndi kutentha.
3.Static pile composting system: Mu dongosolo lino, manyowa a nkhumba amayikidwa mu mulu kapena mulu pamtunda wolimba.Muluwo umasiyidwa kuti uwole pakapita nthawi, ndikutembenuka nthawi zina kuti ulimbikitse mpweya.
4.Anaerobic digestion system: Dongosololi limaphatikizapo kugwiritsa ntchito thanki yotsekedwa kuti iwononge manyowa a nkhumba kupyolera mu njira ya anaerobic digestion.Manyowa amatenthedwa ndi kutentha kwina ndipo amasakanizidwa ndi madzi ndi mabakiteriya kuti alimbikitse kuwonongeka ndi kutulutsa mpweya wa methane.Gasiyo amatha kugwidwa ndikugwiritsidwa ntchito kupanga mphamvu.
Kugwiritsa ntchito zipangizo zowotchera manyowa a nkhumba kungathandize kuchepetsa kuwonongeka kwa chilengedwe cha ulimi wa nkhumba ndi kupanga feteleza wamtengo wapatali omwe angagwiritsidwe ntchito popititsa patsogolo thanzi la nthaka ndi zokolola.Zidazi zimatha kusinthidwa kuti zigwirizane ndi zosowa zenizeni za ntchitoyo ndipo zingathandize kuchepetsa chiopsezo cha kuvulala ndi ngozi zomwe zimagwirizanitsidwa ndi kugwiritsira ntchito pamanja.
