ʻO Nitrogen (a i ʻole nitrogen "N") kekahi o nā mea nui i ʻike ʻia i loko o ka biosphere, a e hana i kahi pōʻaiapuni. Ma kahi o 80% o ka lewa i loaʻa kēia mea, kahi e hoʻopili ʻia ai nā ʻoma ʻelua e hana i ka mole N2. Ikaika loa ka pilina ma waena o kēia mau ʻoma. ʻO Nitrogen, ka mea i loko o ka moku "paʻa", hoʻohana ʻia e nā mea ola āpau. Ke hoʻokaʻawale ʻia nā mole o ka naikokene, komo nā ʻokoma N i nā ʻano ʻokoʻa, e hui pū ʻia me nā ʻoma o nā mea ʻē aʻe. Hoʻohui pinepine ʻia ʻo N me ka oxygen. ʻOiai i loko o ia mau mea i nāwaliwali loa ka pilina o ka naikokene me nā ʻokoma ʻē aʻe, ʻoluʻolu maikaʻi ʻia e nā meaola ola.
Pehea e holo ai ke kalapona nitrogen?
Hoʻopili ka Nitrogen i ke kaiapuni ma o nā ala i paʻa a pili pū kekahi. ʻO ka mea mua, hoʻokuʻu ʻia ʻo N i ka wā o ka decomposition o nā mea i loko o ka lepo. Ke komo ka mea kanu i ka lepo, lawe nā meaolaola i ka naikokene mai iā lākou, a lilo ia i mau mole i hoʻohana ʻia no nā hana metabolic. Hoʻohui ʻia nā ʻĀtoma i koe me nā ʻoma o nā mea ʻē aʻe, a ma hope e hoʻokuʻu ʻia lākou ma ke ʻano o ka ammonium a i ʻole nā amonia iona. A laila hoʻopaʻa paʻa ʻia ka nitrogen e nā mea ʻē aʻe, a ma hope e hana ʻia nā nitrates, a komo i nā mea kanu. ʻO ka hopena, komo ʻo N i ka helehelena o nā mole. Ke pau nā mauʻu, nā laʻalāʻau, nā kumulāʻau a me nā flora ʻē aʻe i loko, komo i ka honua, hoʻi ka nitrogen i ka honua, a laila hoʻomaka hou ka pōʻaiapuni. Lilo ka Nitrogen inā he ʻāpana ia o nā mea sedimentary, hoʻololi ʻia i mau minelala a me nā pōhaku, a i ʻole i ka hana o ka denitrifying bacteria.
Nitrogen i ke kūlohelohe
ʻAʻole ma loko o ka ea nā 4 quadrillion tone o N, akā ma kahi o 20 trillion mau tona i ka Honua Honua. nā tona ʻO kēlā ʻāpana o ka naikokene e noho nei i loko o nā meaola o nā mea ola e pili ana i 100 miliona. ʻO kēia mau mea, 4 miliona mau tona i flora a me nā holoholona, a ʻo ke koena he 96 miliona mau tona i nā microorganism No laila, aia kahi mahele nui o ka naikokene i loko o nā koʻohune, a ma ia mea e hoʻopaʻa ai ʻo N. I kēlā me kēia makahiki, i nā kaʻina hana like ʻole, 100-150 mau tona o ka naikokene e paʻa ana. Loaʻa ka nui o kēia mea i nā mea momona mineral e hana ai nā kānaka.
No laila, ʻo ka pōʻaiapuni N kahi ʻāpana hoʻohui o nā hana kūlohelohe. Ma muli o kēia, ua hopena nā hoʻololi like ʻole. Ma ke ʻano he hopena o ka hana anthropogenic, aia kahi loli i ke kalapona nitrogen i loko o ke kaiapuni, akā i kēia manawa ʻaʻole kēia kahi pilikia nui i ke kaiapuni.
