Nitrogen, Nitrate Nitrogen, Nitrite Nitrogen le Kjeldahl Nitrogen

Nitrogen ke ntho ea bohlokoa e ka bang teng ka mefuta e fapaneng metsing le mobung oa tlhaho. Kajeno re tla bua ka likhopolo tsa naetrojene e feletseng, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen le Kjeldahl nitrogen. Total nitrogen (TN) ke sesupo se atisang ho sebelisoa ho metha kakaretso ea lintho tsohle tsa naetrojene metsing. E kenyelletsa ammonia nitrogen, naetrojene ea nitrate, naetrojene ea nitrite le lintho tse ling tsa naetrojene tse kang nitrate le nitrate. Ammonia nitrogen (NH3-N) e bolela motsoako o kopaneng oa ammonia (NH3) le ammonia oxides (NH4+). Ke naetrojene ea alkaline e fokolang 'me e ka fumanoa ho tsoa ho likokoana-hloko le lik'hemik'hale tsa metsi. Nitrate nitrogen (NO3-N) e bua ka bongata ba nitrate (NO3 -). Ke naetrojene e nang le asiti e matla le mofuta o ka sehloohong oa naetrojene. E ka tsoa tšebetsong ea tlhaho ea metsi ho tsoa ho ammonia nitrogen le naetrojene ea tlhaho metsing. Nitrite nitrogen (NO2-N) e bua ka bongata ba nitrite (NO2 -). Ke naetrojene e nang le asiti e fokolang le selelekela sa naetrojene ea nitrate, e ka fumanoang ka ts'ebetso ea likokoana-hloko le lik'hemik'hale metsing. Kjeldahl nitrogen (Kjeldahl-N) e bolela kakaretso ea ammonia oxides (NH4+) le nitrogen nitrogen (Norg). Ke naetrojene ea ammonia e ka fumanoang ka likokoana-hloko le lik'hemik'hale ka metsing. Naetrojene ka metsing ke karolo ea bohlokoa e ka amang boleng ba metsi, maemo a tikoloho, le kholo le nts'etsopele ea lintho tse phelang metsing. Ka hona, ho bohlokoa haholo ho hlokomela le ho laola kakaretso ea nitrogen, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, le Kjeldahl nitrogen metsing. Liteng tsa naetrojene kaofela ke sesupo sa bohlokoa sa ho metha kakaretso ea lintho tsa naetrojene metsing. Ka kakaretso, kakaretso ea naetrojene metsing e lokela ho ba ka har'a mefuta e itseng. Boemo bo phahameng haholo kapa bo tlase haholo bo tla ama boleng ba metsi a metsi. Ho feta moo, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, le Kjeldahl nitrogen le tsona ke matšoao a bohlokoa bakeng sa ho lemoha lintho tsa naetrojene metsing. Litaba tsa bona le tsona li lokela ho ba ka har'a mefuta e itseng. Boemo bo phahameng haholo kapa bo tlase haholo bo tla ama boleng ba metsi a metsi. E le karolo ea limatlafatsi, naetrojene e kenngoa matšeng, 'me phello e tobileng ka ho fetisisa ke eutrophication:
1) Ha matša a le boemong ba tlhaho, ha e le hantle ke oligotrophic kapa mesotrophic. Ka mor'a ho fumana tlhahiso ea limatlafatsi tse sa tloaelehang, boemo ba limatlafatsi ba 'mele oa metsi bo eketseha, bo ka khothalletsang nts'etsopele ea metso le limela tsa limela tsa metsing ka har'a mefuta e itseng,' me ho matlafatsa limatlafatsi ha ho totobetse.
2) Ka kenyelletso e tsoelang pele ea limatlafatsi tse kang naetrojene, sekhahla sa ho sebelisoa ha limatlafatsi ke limela tsa metsing se tlaase ho feta sekhahla sa ho eketseha ha nitrogen. Keketseho ea limatlafatsi e etsa hore algae e ate ka bongata, butle-butle e fokotsa ho pepeseha ha 'mele oa metsi,' me nts'etsopele ea limela tsa metsing e thibetsoe ho fihlela e nyamela. Ka nako ena, letša le fetoha ho tloha letša la mofuta oa joang ho ea ho letša la mofuta oa algae, 'me letša lena le bontša litšobotsi tsa eutrophication.
Hajoale, linaha tse ngata li na le melao e thata mabapi le litaba tsa naetrojene tse kang naetrojene e felletseng, ammonia nitrogen, naetrojene ea nitrate, naetrojene ea nitrite le naetrojene ea Kjeldahl metsing. Haeba melaoana e tlōtsoe, e tla ba le phello e tebileng ho boleng ba metsi le tikoloho ea tikoloho ea 'mele oa metsi. Ka hona, motho e mong le e mong o lokela ho ela hloko tlhokomelo le taolo ea lintho tsa naetrojene libakeng tsa metsi ho netefatsa hore boleng ba metsi a mehloli ea metsi bo finyella litekanyetso tsa naha.
Ka kakaretso,naetrojene kaofela, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen le Kjeldahl nitrogenke matšoao a bohlokoa a lintho tsa nitrogen metsing. Likahare tsa tsona ke sesupo sa bohlokoa sa boleng ba metsi, 'me tlhokomelo le taolo li bohlokoa haholo. Ke ka ho beha leihlo le ho laola lintho tse nang le naetrojene ka metsing feela moo re ka netefatsang hore boleng ba metsi bo kopana le maemo le ho sireletsa bophelo bo botle ba 'mele oa metsi.
