ʻO ka Nitrogen kekahi mea nui e hiki ke noho ma nā ʻano like ʻole i ka wai a me ka lepo ma ke ʻano. I kēia lā, e kamaʻilio mākou e pili ana i nā manaʻo o ka nui o ka nitrogen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen a me Kjeldahl nitrogen. ʻO ka huina nitrogen (TN) he hōʻailona maʻamau i hoʻohana ʻia no ke ana ʻana i ka nui o nā mea nitrogen a pau i loko o ka wai. Loaʻa iā ia ka ammonia nitrogen, nitrate nitrogen, nitrite nitrogen a me kekahi mau mea nitrogen e like me ka nitrate a me ka nitrate. 'Amonia nitrogen (NH3-N) pili i ka hui 'ana o ka ammonia (NH3) a me ammonia oxides (NH4+). He naikokene alkaline nāwaliwali ia a hiki ke loaʻa mai nā hopena olaola a me nā kemika i loko o ka wai. ʻO ka nitrogen nitrate (NO3-N) pili i ka ʻike o ka nitrate (NO3 -). ʻO ia ka waikawa acidic ikaika a me ke ʻano nui o ka nitrogen. Hiki ke loaʻa mai ka hana olaola o ka wai mai ka naikokene ammonia a me ka nitrogen organik i loko o ka wai. ʻO ka nitrite nitrogen (NO2-N) pili i ka neʻe o ka nitrite (NO2 -). He naikokene ʻakika nāwaliwali ia a he mea mua o ka naikokene nitrate, hiki ke loaʻa ma o ka hoʻololi ʻana o ke kino a me ke kemika i ka wai. Kjeldahl nitrogen (Kjeldahl-N) pili i ka huina o ammonia oxides (NH4+) a me organik nitrogen (Norg). ʻO ia ka ammonia nitrogen e hiki ke loaʻa ma o ka hoʻololi ʻana o ke kino a me ke kemika i loko o ka wai. ʻO ka Nitrogen i loko o ka wai kahi mea nui e hiki ke hoʻopilikia i ka maikaʻi o ka wai, nā kūlana kaiaola, a me ka ulu a me ka ulu ʻana o nā mea ola wai. No laila, he mea nui ka nānā ʻana a me ka mālama ʻana i ka nui o ka nitrogen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, a me Kjeldahl nitrogen i loko o ka wai. He hōʻailona koʻikoʻi ka maʻiʻo o ka huina nitrogen no ke ana ʻana i ka nui o nā mea nitrogen i loko o ka wai. ʻO ka maʻamau, pono ka nui o ka nitrogen i loko o ka wai i loko o kahi kikoʻī. ʻO ke kiʻekiʻe a i ʻole ka haʻahaʻa haʻahaʻa e pili ana i ka maikaʻi o ka wai. Eia kekahi, ʻo ka ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, a me Kjeldahl nitrogen kekahi mau hōʻailona koʻikoʻi no ka ʻike ʻana i nā mea nitrogen i loko o ka wai. Pono nō hoʻi kā lākou ʻike i loko o kahi ākea. ʻO ke kiʻekiʻe a i ʻole ka haʻahaʻa haʻahaʻa e pili ana i ka maikaʻi o ka wai. Ma ke ʻano he mea meaʻai, hoʻokomo ʻia ka nitrogen i loko o nā loko, a ʻo ka hopena pololei loa ʻo ia ka eutrophication:
1) Ke noho maoli nā loko, he oligotrophic a mesotrophic paha. Ma hope o ka loaʻa ʻana o ka meaʻai meaʻai exogenous, piʻi ka pae nutrient o ke kino wai, hiki ke hoʻoikaika i ka ulu ʻana o nā aʻa a me nā kumu o nā mea kanu wai i loko o kekahi ʻano, a ʻaʻole maopopo ka hoʻonui ʻana i ka meaʻai.
2) Me ka hoʻokomo mau ʻana o nā meaʻai e like me ka nitrogen, ʻoi aku ka haʻahaʻa o ka hoʻohana ʻana i nā mea kanu e nā mea kanu wai ma mua o ka piʻi ʻana o ka nitrogen. ʻO ka hoʻonui ʻana i nā meaʻai e hoʻonui ai i ka limu i ka nui, e hōʻemi mālie ana i ka ʻike o ke kino wai, a ua kaohi ʻia ka ulu ʻana o nā mea kanu wai a hiki i ka nalo ʻana. I kēia manawa, hoʻololi ka loko mai kahi loko mauʻu i kahi loko algae, a hōʻike ka loko i nā ʻano o ka eutrophication.
I kēia manawa, nui nā ʻāina i nā hoʻoponopono koʻikoʻi e pili ana i ka ʻike o nā mea nitrogen e like me ka huina o ka nitrogen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen a me Kjeldahl nitrogen i loko o nā kino wai. Inā hōʻino ʻia nā lula, he hopena koʻikoʻi ia i ka maikaʻi o ka wai a me ke kaiaola o ke kino wai. No laila, pono nā kānaka a pau i ka nānā ʻana a me ka mālama ʻana i nā mea nitrogen i loko o nā kino wai e hōʻoia i ka maikaʻi o ka wai o nā kino wai i nā kūlana ʻāina.
I ka hōʻuluʻulu manaʻo,ka nui o ka naikokene, ka amonia naikokene, ka nitrate nitrogen, nitrite nitrogen a me ka Kjeldahl nitrogenhe mau hōʻailona koʻikoʻi o nā mea nitrogen i loko o nā kino wai. ʻO kā lākou ʻike he hōʻailona koʻikoʻi o ka maikaʻi o ka wai, a he mea nui ka nānā ʻana a me ka mālama ʻana. Ma o ka nānā pono ʻana a me ka mālama ʻana i nā mea nitrogen i loko o nā kino wai hiki iā mākou ke hōʻoia i ka maikaʻi o ka wai i nā kūlana a pale i ke olakino o ke kino wai.
