Feteleza: 90% ya urea wopanga imagwiritsidwa ntchito ngati feteleza. Amawonjezedwa m'nthaka ndipo imapereka nayitrogeni pazomera. Zotsika mtengo (zosakwana 0.03%) urea zimagwiritsidwa ntchito ngati feteleza wamawu. Amasungunuka m'madzi ndikuyika pamasamba a mbewu, makamaka zipatso ndi zipatso.
Feteleza wa Urea ali ndi mwayi wopereka zinthu zakuthwa kwa nayitrogeni, zomwe ndizokhudzana ndi kagayidwe kake ndipo imagwirizana mwachindunji ndi kuchuluka kwa masamba ndi masamba omwe amayatsa photosynthesis. Kuphatikiza apo, nayitrogeni alipo m'mavitamini ndi mapuloteni, ndipo amakhudzana ndi mapuloteni omwe ali ndi mapuloteni.
Urea amagwiritsidwa ntchito m'mitundu yosiyanasiyana ya mbewu. Umuna umafunikira chifukwa dothi limataya nayitrogeni yambiri mukatha kukolola. Tizilombo tambiri timagwiritsidwa ntchito m'nthaka, zomwe zikuyenera kugwira bwino ntchito komanso zolemera m'mabakiteriya. Ntchito ikhoza kupangidwa pakubzala kapena m'mbuyomu. Kenako, urea ndi hydrolyzed ndikuwola.
Chisamaliro chiyenera kutengedwa mukamagwiritsa ntchito urea molondola m'nthaka. Ngati imagwiritsidwa ntchito pamtunda, kapena ngati sichikuphatikizidwa munthaka pogwiritsa ntchito mvula yoyenera, mvula, kapena kuthilira, ammonia adzatuluka ndipo kutayika ndikofunikira kwambiri. Kuperewera kwa nayitrogeni mu zomera kumawonetsedwa mu kuchepa kwa masamba ndi kuchepa kwazinthu zopangira.
Umuna wa tsamba: Umuna wa tsamba ndi mchitidwe wakale, koma nthawi zambiri amalankhula, kugwiritsa ntchito michere yofananira ndi dothi ndikochepa, makamaka malinga ndi kuchuluka kwakukulu. Komabe, zolemba zina zakumayiko zimawonetsa kuti kugwiritsa ntchito urea urea kumatha kuchepetsa kuchuluka kwa feteleza womwe umayikidwa m'nthaka osazengereza magwiridwe, kukula, ndi zipatso. Kafukufuku wawonetsa kuti kupopera mbewu mankhwala owiritsa ndi urea pang'ono ndi kothandiza monga kupopera mbewu mankhwalawa. Kuphatikiza pa mapulani othandiza mapangidwe, izi zimatsimikizira chizolowezi chogwiritsa ntchito feteleza molumikizana ndi mitundu ina yaulimi.
Mankhwala ndi mapulasitikidwe: urea limapezeka pazenera, pulasitiki, ma recrists, maikutu, mapepala, ndi kumaliza ntchito kwa malembedwe, pepala, ndi zitsulo.
Chiwonetsero cha ziweto: Urea amasakanikirana ndi ng'ombe ndi masitaitrogeni, zomwe ndizofunikira kuti mapangidwe a protein.
Kupanga Kupanga: urea formaldehyde utoto ndi mateni ena ali ndi ntchito zosiyanasiyana pamakampani, monga kupanga plywood Prelwood. Amagwiritsidwanso ntchito modzola komanso zotupa.
