Nitrogen umquba: izinhlobo kanye nokusungulwa

Nitrogen Umanyolo ikhiqizwa ammonia, imiswe phakathi neminyaka nitrogen ukuphendula eyatholakala kusukela emoyeni nge-hydrogen okuyinto. Ukuze ukusabela kudinga umfutho ophakeme, ukuba khona yelikhono kanye lokushisa okungenani 400.

Nitrogen umquba: Izinhlobo

Okuvame kakhulu kukamanyolo amaminerali nitrogen kuyinto urea, okuyinto owaziwa ngaphansi kwencazelo "urea", futhi ammonium nitrate.

Lesi sakamuva kwakwakhe noma ammonium nitrate iyona Umanyolo ephumelela kunazo equkethe okungenani nitrogen lesithathu. Ngokubukeka, ammonium nitrate kuyinto encibilikayo kalula emanzini, elimbudumbudu ezimhlophe ngaphandle iphunga abalulekile kanye nosayizi esincane.

Ukuthandwa phakathi abashayeli bamaloli, abalimi kanye balimi kwadingeka nitrate ngenxa nokuqukethwe kwalo nitrogen okusezingeni eliphezulu, ezingasetshenziswa ukwandisa ezithela ngenkathi kuhlonishwa isikhathi futhi isicelo amazinga.

Nitrogen umquba nabo emhlabathini nitrogen aqhelelene, ihamba ngenkuthalo enhlabathini izingqimba. Ngakho-ke, yini ucobekile, permeable, ngobuningi oswakanyiswe nenhlabathi nitrate kuyadingeka ukwenza ngesikhathi isitshalo esiphezulu idinga i-nitrogen. Lo mthetho kuzovumela okugcwele ngesikhathi esifanele ukuhlinzeka ezibalulekile zokutshala izinto nomanyolo ngesikhathi esifanayo ukuqeda overruns ngenxa leaching lwalo izingqimba engezansi zenhlabathi, akutholakali ohlelweni impande.

Ukuphumelela kungathuthukiswa efaka umquba athutha ukuxuba Umanyolo nitrogen ne-potassium ne phosphorus podsypaniem ngokushesha ngaphambi inhlabathi.

Ukusetshenziswa ammonium nitrate ngoba ukuvundiswa ivumela ukuthuthukiswa ngokushesha mass oluhlaza, futhi ukuthuthukisa gluten ukwandisa iphesenti namaprotheni okusanhlamvu.

Ngakusasa funa ketshezi kuyinto urea, okuyinto simele umquba nitrogen akhiqizwa uhlobo zithutha elincane abangenalo iphunga nombala, kalula oncibilikayo emanzini. Ngokuphambene, ammonium nitrate, urea kancane hygroscopic. Iqukethe cishe amaphesenti angu-50 e-nitrogen, lapho Umanyolo has a ukumelana leaching. Ngenxa yalaba izakhiwo, ungakwazi zithole imiphumela emihle ngisho ne Umanyolo ku amaxhaphozi, wapheka-podzol nenhlabathi.

Urea okumele asetshenziswe njengoba i-yokudla ngesikhathi ukutshala entwasahlobo, kanye ukuvundiswa impande ngesikhathi yokukhula. Umthelela esiphezulu bungatholakala ngokuhlanganisa urea nenhlabathi azibukhali nge liming nokungeza umanyolo kanye phosphate umquba.

Olunye uhlobo, bohlanga "umquba nitrogen" kuyinto amanzi ammonia, amanani aphansi kanye kalula yokusetshenziswa ukuthi baye bavumela ukuba lusakazwe kabanzi kwezolimo.

amanzi ammonia yethulwa enhlabathini ngaphambi kokuhlwanyela entwasahlobo njengoba base Umanyolo, bese at esigabeni sokuqala namasiko akhona, ikakhulu lapho ukufuneka kakhulu nitrogen. Ukuze ugcine i-ammonia eziqukethwe isixazululo, ngemuva kokwenza Umanyolo lishumekwe phansi hhayi ngaphansi kuka 10 amasentimitha.
