Ambiri amadziwa bwino momwe nayitrogeni yamadzimadzi imagwiritsidwira ntchito m'ma laboratories ndi m'zipatala posungira zitsanzo. Komabe, kugwiritsidwa ntchito kwake tsiku ndi tsiku kukukulirakulira, kuphatikizapo kugwiritsa ntchito kwake posunga nsomba zokwera mtengo kuti zigwiritsidwe ntchito paulendo wautali.
Kusunga nsomba za m'nyanja kumabwera m'njira zosiyanasiyana, monga zomwe zimapezeka m'masitolo akuluakulu, komwe nsomba za m'nyanja zimagona pa ayezi popanda kuzizira kwambiri. Komabe, njira imeneyi imachepetsa nthawi yosungira ndipo siyoyenera kunyamulidwa mtunda wautali.
Mosiyana ndi zimenezi, kuziziritsa nsomba ndi nayitrogeni yamadzimadzi ndi njira yoziziritsira mofulumira komanso yothandiza yomwe imawonjezera kutsitsimuka ndi thanzi la nsomba.
Izi zili choncho chifukwa kutentha kochepa kwambiri kwa nayitrogeni yamadzimadzi, komwe kumafika madigiri -196 Celsius, kumalola kuti nsomba zizizizira mofulumira, kuchepetsa kupangika kwa makristalo akuluakulu a ayezi panthawi yozizira, zomwe zingayambitse kuwonongeka kosafunikira kwa maselo. Zimasunga bwino kukoma ndi kapangidwe ka nsomba.
Njira yogwiritsira ntchito nayitrogeni wamadzimadzi poziziritsa nsomba ndi yosavuta. Choyamba, nsomba zatsopano zimasankhidwa, zinthu zosafunikira ndi zodetsa zimachotsedwa, ndipo zimatsukidwa bwino. Kenako, nsomba zimayikidwa mu thumba la pulasitiki lotsekedwa, mpweya umatuluka, ndipo thumba limakanizidwa momwe zingathere. Kenako thumba limayikidwa mu thanki ya nayitrogeni wamadzimadzi, komwe limakhalabe mpaka nsombazo zitazizira kwathunthu ndipo zikonzeka kugwiritsidwa ntchito mtsogolo.
Mwachitsanzo, matanki osungiramo nayitrogeni wamadzimadzi a m'nyanja a Shengjie, omwe amagwiritsidwa ntchito makamaka pozizira nsomba zapamwamba kwambiri, amakhala ndi kuzizira mwachangu, nthawi yayitali yosungidwa, ndalama zochepa zogulira zida ndi zogwirira ntchito, osagwiritsa ntchito mphamvu, palibe phokoso, sasamalira kwambiri, amasunga mtundu woyambirira wa nsomba, kukoma, ndi zakudya.
Chifukwa cha kutentha kochepa kwambiri kwa nayitrogeni yamadzimadzi, njira zodzitetezera ziyenera kutengedwa poigwira kuti isakhudze khungu kapena maso mwachindunji, zomwe zingayambitse chisanu kapena kuvulala kwina.
Ngakhale kuzizira kwa nayitrogeni yamadzimadzi kumapereka zabwino zambiri, ndikofunikira kudziwa kuti sikungakhale koyenera mitundu yonse ya nsomba zam'madzi, chifukwa zina zimatha kusintha kukoma ndi kapangidwe kake pambuyo pa kuzizira. Kuphatikiza apo, kutenthetsa bwino kumafunika musanadye nsomba zam'madzi zozizira za nayitrogeni kuti chakudya chikhale chotetezeka.
