urea granular ammonium sulphate fertilizer
ʻO Urea, ʻike ʻia hoʻi ʻo ka carbamide, he diamide o ka ʻakika carbonic me ke ʻano molekala CO(NH2)2.Hoʻohana nui ia i ka ʻoihana a me ka mahiʻai.Ma ka ʻoihana, ʻo ka urea ka 28.3% o ka hoʻohana ʻana: melamine resins, melamine, melamine acid, etc. Hiki ke hoʻohana ʻia ma ke ʻano he meaʻai meaʻai a ma ka ʻoihana lāʻau lapaʻau a me nā mea hoʻonaninani.Ma ka mahiʻai, hoʻohana nui ʻia ka urea e hana i nā mea hoʻohuihui a i hoʻopili pololei ʻia ma ke ʻano he mea hoʻomomona, ʻoi aku ka nui o ka hoʻohana ʻana o Urea i ka 70% o kona hoʻohana ʻana.

ʻO nā mea momona a i ʻole ka pauda ʻo NPK 15-5-25 ka mea hoʻopuehu ma muli o ka Nitro-sulfur.
He mea hoʻohuihui ia me ka ammonium nitrate e like me ke kumu naikokene, e hoʻohui ana i ka phosphorus, potassium a me nā mea hoʻohuihui mea ʻē aʻe e hana i kahi kiʻekiʻe o ka N, P, K mea hoʻohuihui.Loaʻa i kāna huahana nā nitrate a me ka ammonium nitrogen.ʻO nā huahana nui ka ammonium nitrate phosphorus a me ka ammonium nitrate phosphorus potassium.He mea hoʻomomona koʻikoʻi, kūpono no ka paka, kānana, melon, nā mea kanu, nā lāʻau huaʻai a me nā mea kanu waiwai ʻē aʻe a me ka lepo alkaline a me nā wahi karst, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka lepo alkaline a me nā wahi karst terrain ma mua o ka urea.

Hoʻopaʻa ʻia nā mea hoʻohuihui ʻāina e hōʻailona ʻia nā mea kanu i loaʻa i ka chlorine me ka chloride ion content, e like me ka haʻahaʻa chloride (loaʻa ka chloride ion 3-15%), ka medium chloride (loaʻa ka chloride ion 15-30%), kiʻekiʻe chloride (loaʻa ka chloride ion. 30% a ʻoi aku paha).
ʻO ka hoʻohana kūpono o ka palaoa, ka palaoa, ka asparagus a me nā mea kanu ʻē aʻe ʻaʻole pono wale nō, akā maikaʻi nō hoʻi e hoʻomaikaʻi i nā hua.
Ma keʻano laulā, ʻo ka hoʻohana ʻana i ka chlorine-based compound fertilizer, paka, ʻuala, ʻuala, watermelon, hua waina, sugar beets, kāpeti, pepa, eggplant, soybeans, letus a me nā mea kanu ʻē aʻe e kūʻē i ka chlorine he hopena maikaʻi ʻole i ka hua a me ka maikaʻi. e hoemi ana i na pomaikai waiwai o ia mau mea kanu dala.I ka manawa like, ka chlorine-based compound fertilizer i loko o ka lepo e hana i ka nui o nā koena chlorine ion, maʻalahi e hoʻohui i ka lepo, salinization, alkalinization a me nā mea ʻē aʻe i makemake ʻole ʻia, no laila e hōʻino ana i ka ʻāina lepo, i hiki ai i ka mea kanu ke hiki ua hoemiia.
