Kuzizira mwachangu ndi njira yabwino yochepetsera zinyalala za chakudya. Ndi uttrogen mwachangu mwachangu mwachangu mwachangu kuzizira kozizira, chakudya chimatha kukhala chisanu nthawi yochepa kwambiri ndikusunga utoto wake komanso kukoma kwake. Zida za nitrogen mwachangu zimachepetsa kutentha kwa chakudya ku --18 digiri kapena m'munsi, pokweza chakudya chokwanira paulendo ndi kusungidwa.
M'mayiko ambiri otukuka, chifukwa choperewera kwa malo osungira ndi mayendedwe, zinyalala ndi masamba ndi masamba omwe amatha kukhala 50%. Zida za nitrogen mwachangu zimathandizira opanga zakudya zimathetsa zakudya zowonongeka izi, zimachepetsa kutayika nthawi yoyendera, ndikukhala ndi chakudya chamtengo wapatali. Tekinoloje imasinthasintha ndipo itha kugwiritsidwa ntchito kuthira chakudya popanga kapena mutatha kukonza, kuthana ndi chakudya kutaya zinthu kumayiko onse.
