Nitrogen chiv: hom thiab muaj pes tsawg leeg

Nitrogen chiv ua los ntawm ammonia, uas yog tsim nyob rau thaum lub sij hawm cov tshuaj tiv thaiv nitrogen tau los ntawm cov huab cua nrog hydrogen. Rau cov tshuaj tiv thaiv yuav tsum tau kub siab, lub xub ntiag ntawm lub catalysts thiab qhov kub thiab txias ntawm tsawg kawg yog 400 degrees.

Nitrogen chiv: Hom

Cov feem ntau mineral chiv ntawm nitrogen yog urea, uas yog zoo dua lub npe hu nyob rau hauv lub ntsiab txhais ntawm "urea", thiab ammonium nitrate.

Cov yav tas compound los yog ammonium nitrate yog qhov zoo tshaj chiv uas muaj tsawg kawg yog ib tug thib peb nitrogen. Nyob rau hauv tsos, ammonium nitrate yog yooj yim soluble nyob rau hauv dej, dawb granules tsis tseem ceeb tsw thiab loj me me.

Muaj koob meej ntawm truckers, liaj ua teb thiab gardeners muaj nitrate vim nws cov high nitrogen cov ntsiab lus, uas muaj peev xwm ho nce loo thaum saib lub sij hawm thiab daim ntawv thov nqi.

Nitrogen chiv nyob rau hauv kev sib cuag nrog cov av yog raug rho tawm nitrogen, uas tsiv koom nyob rau hauv cov av khaubncaws sab nraud povtseg. Yog li ntawd, drained, permeable, nplua mias moistened xau nitrate yog tsim nyog los ua thaum lub sij hawm ntawm ntau tsob nroj yuav tsum tau nitrogen. Qhov no txoj cai yuav cia tus puv thiab nyob rau lub sij hawm los muab nqi cog cov ntaub ntawv thiab chiv nyob rau tib lub sij hawm tshem tawm overruns vim nws leaching mus rau hauv lub qis khaubncaws sab nraud povtseg ntawm cov av, uas yog tsis muaj nyob rau hauv paus system.

Efficiency yuav tau zoo tuaj fertilizing mechanically nws cov nitrogenous chiv nrog poov tshuaj thiab phosphorus podsypaniem tam sim ntawd ua ntej cov av.

Kev siv ntawm ammonium nitrate rau fertilizing tso cai sai kev loj hlob ntawm ntsuab loj, thiab txhim khu lub gluten ua rau kom cov feem pua ntawm cov nqaijrog nyob rau hauv cereals.

Cov tom ntej no thov tshuaj yog urea, uas nruab nrab yog ib tug nitrogenous chiv nyob rau hauv daim ntawv ntawm cov me me pellets muaj tsis muaj tsw thiab xim, nkag soluble nyob rau hauv cov dej. Rau hauv sib piv, ammonium nitrate, urea tsawg hygroscopic. Nws muaj ze li ntawm 50 feem pua nitrogen, nyob rau lub chiv muaj ib tug high kuj mus leaching. Tsaug rau cov khoom, koj yuav cuag tau zoo txawm nrog chiv rau nraum, sod-podzol xau.

Urea yuav tsum tau ua ntawv thov raws li ib tug pre-noj thaum lub sij hawm lub caij nplooj ntoos hlav sau qoob, raws li zoo raws li lub hauv paus fertilizing thaum lub sij hawm loj hlob rau lub caij. Qhov siab tshaj plaws nyhuv yuav ua tau tiav los ntawm combining urea nyob rau hauv acidic xau nrog Liming thiab ntxiv potash thiab ntsev chiv.

Lwm yam, teej tug mus rau cov pab pawg neeg "nitrogenous chiv" yog ammonia dej, uas tsis muaj nqi thiab yooj yim ntawm kev siv uas tau tso cai nws mus rau kis dav nyob rau hauv ua liaj ua teb.

Ammonia dej yog nkag tau rau hauv cov av ua ntej sowing caij nplooj ntoos hlav raws li ib puag chiv, thiab ces nyob rau thawj zaug rau theem ntawm kab lis kev cai, tshwj xeeb tshaj yog thaum siab thov rau nitrogen. Yuav kom cov ammonia muaj nyob rau hauv cov tshuaj, tom qab ua lub chiv yog kos nyob rau hauv lub hauv av tsis tsawg tshaj li 10 centimeters.
