Nitrojene (kapa naetrojene "N") ke e 'ngoe ea likarolo tsa bohlokoahali tse fumanehang ho biosphere, mme e tla etsa potoloho. Moea o ka bang 80% o na le elemente ena, eo ho eona liathomo tse peli li kopaneng ho etsa molek'hule ea N2. Tlamo pakeng tsa liathomo tsena e matla haholo. Nitrojene, e "boemong bo tlamang", e sebelisoa ke lintho tsohle tse phelang. Ha limolek'hule tsa naetrojene li arohana, liathomo tsa N li nka karolo liketsong tse fapaneng, li kopane le liathomo tsa likarolo tse ling. N hangata e kopantsoe le oksijene. Kaha linthong tse joalo khokahano ea naetrojene le liathomo tse ling e fokola haholo, e ananeloa hantle ke lintho tse phelang.
Potoloho ea naetrojene e sebetsa joang?
Nitrojene e potoloha tikolohong ka litsela tse koetsoeng le tse hokahaneng. Pele, N e lokolloa nakong ea ho senyeha ha lintho mobung. Ha limela li kena mobung, lintho tse phelang li ntša naetrojene ho tsona, ka tsela eo li li fetola limolek'hule tse sebelisetsoang ts'ebetso ea ts'ebetso ea metsolic. Liathomo tse setseng li kopana le liathomo tsa likarolo tse ling, kamora moo li lokolloa ka mofuta oa ammonium kapa ammonia ions. Ebe naetrojene e tlangoa ke lintho tse ling, kamora moo ho etsoa li-nitrate, tse kenang limela. Ka lebaka leo, N e nka karolo ponahalong ea limolek'hule. Ha joang, lihlahla, lifate le limela tse ling li shoa, li kena mobung, naetrojene e khutlela mobung, kamora moo potoloho e qala hape. Nitrojene ea lahleha haeba e le karolo ea lintho tse sedimentary, e fetotsoe liminerale le majoe, kapa nakong ea tšebetso ea ho senya baktheria.
Nitrojene ka tlhaho
Moea ha o na litone tse ka bang 4 tsa li-quadrillion tsa N, empa li na le lithane tse ka bang limilione tse likete tse 20 Leoatleng la Lefatše. lithane. Karolo eo ea naetrojene e teng linthong tse phelang e ka ba limilione tse 100. Ho tsena, lithane tse limilione tse 4 li limela le liphoofolo, 'me tse setseng tse limilione tse 96 li likokoana-hloko. Kahoo, karolo e kholo ea naetrojene e teng libaktheria, tseo N e tlamiloeng ka tsona. Selemo se seng le se seng, nakong ea lits'ebetso tse fapaneng, ho tlamelloa lithane tse 100-150 tsa nitrojene. Palo e kholo ka ho fetesisa ea ntho ena e fumanoa menonong ea diminerale eo batho ba e hlahisang.
Kahoo, potoloho ea N ke karolo ea bohlokoa ea lits'ebetso tsa tlhaho. Ka lebaka la sena, liphetoho tse fapaneng lia fella. Ka lebaka la ts'ebetso ea anthropogenic, ho na le phetoho potolohong ea naetrojene tikolohong, empa ho fihlela joale sena ha se na kotsi e kholo tikolohong.
