1. Ma ka mahiʻai, pono ka hoʻohana ʻana i nā mea kanu no ka hoʻoulu ʻana i ka ulu olakino maikaʻi a hoʻonui i nā hua hua.
2. ʻO ka urea nui He ammonia ʻokoʻa a me ka ʻono paʻakai a he mea hoʻomomona waiwai nui i ka nitrogen e pāʻani nui i ka hoʻoikaika ʻana i ka ulu ʻana o nā mea kanu. Ke hoʻohana ʻia i ka lepo, e hana ia i kahi kaʻina hydrolysis, e hoʻokuʻu ana i nā ion ammonium i maʻalahi ʻia e nā aʻa mea kanu. Hoʻonui kēia i ka lawe ʻana i ka nitrogen, e hoʻoikaika i ka ulu a me ka ulu ʻana o nā mea kanu.
3. Ma ka mahiʻai, pono ka hoʻohana ʻana i nā mea kanu e hoʻoikaika i ka ulu ʻana o nā mea kanu maikaʻi a hoʻonui i nā hua hua.
1. ʻO kekahi o nā pōmaikaʻi nui o ka granular urea ʻo ia kona hoʻoheheʻe kiʻekiʻe i ka wai a me nā ʻano waiʻona like ʻole, e maʻalahi ai ka hoʻohana ʻana a me ka hōʻoia ʻana i ka lawe ʻana i nā meaʻai e nā mea kanu.
2. ʻO kona maʻalahi a me ka launa pū ʻana me nā ʻano noi like ʻole e like me ka hoʻolaha ʻana, ka lole luna a i ʻole ka fertigation ka mea i koho mua ʻia no ka poʻe mahiʻai e ʻimi nei i ka hoʻomaʻamaʻa ʻana i nā hana hoʻokele waiwai.
3. ka hui kemika o granularurea, me kona decomposition i biuret, ammonia a me ka cyanic acid i nā mahana kiʻekiʻe, e hōʻike ana i kona hiki ke hoʻokuʻu ʻia a me nā hopena lōʻihi i ka meaʻai mea kanu. He mea kūpono kēia no ka hoʻolako mau ʻana i nā meaʻai i loko o ka wā ulu, e hōʻemi ana i ka pono o nā noi hou pinepine.
