Nitrogen fetiraiza: mhando uye sezvamunoita

Nitrogen fetiraiza yakabereka kubva amoniya, iyo yakaumbwa mumakore maitiro senitrogen yakawanikwa kubva mumhepo rehydrogen. Nokuti kuita zvinoda mukuru kumanikidzwa, pamberi catalysts uye tembiricha rworwendo dzinenge 400.

Nitrogen fetiraiza: Types

Vakawanda chicherwa fetiraiza ose senitrogen ndiko urea, riri nani kuzivikanwa pasi tsanangudzo "urea", uye Ammonium nitrate.

Zvapedzisira remubatanidzwa kana Ammonium nitrate ndiyo inonyatsobudirira fetiraiza ine kanenge imwe senitrogen wechitatu. In chitarisiko, Ammonium nitrate iri nyore soluble nemvura, granules chena pasina chinokosha kwakanaka uye diki kukura.

Popularity pakati truckers, varimi uye kurima gadheni vaiva nitrate nokuda kwayo yakakwirira senitrogen kugutsikana, izvo zvinogona yekudyidzana kuwedzera goho apo pamusoro nguva uye kushanda prices.

Nitrogen fetiraiza neVadzidzi pasi riri yoga senitrogen, izvo chinoita achishingaira mune ivhu akaturikidzana. Naizvozvo, vakapedzwa, permeable, zvikuru yakakanyiwa nevhu nitrate zvinokosha kuti panguva kunonyanyisa chirimwa inoda senitrogen. Kutonga uku achabvumira zvizere uye panguva yakakodzera kupa inokosha yokudyara zvinhu uye fetiraiza panguva imwe chete kubvisa overruns nokuda kwayo leaching munzvimbo dzapasi akaturikidzana ivhu, iyo isipo midzi.

Kunyatsoshanda inogona kunatsiridzwa kuberekesa mechanically nokusanganisa ari nitrogenous fetiraiza pamwe potassium uye phosphorus podsypaniem pakarepo pamberi ivhu.

Kushandiswa Ammonium nitrate nokuda kuberekesa achibvumira nokukurumidza kukura mutema guru, uye chiwedzere gluten kuwedzera chikamu mapurotini mune zviyo.

Inotevera kudiwa fuma iri urea, iro rinomiririra nitrogenous fetiraiza anogadzirwa muchimiro pellets duku asina kwakanaka uye ruvara, nyore soluble mumvura. Kusiyana, Ammonium nitrate, urea zvishoma hygroscopic. Rine anenge 50 muzana senitrogen, sezvamakaropafadzwa fetiraiza ane mukuru kuramba leaching. Nemhaka ehupfumi izvi, unogona kubudirira zvakanaka kunyange fetiraiza pamusoro wetlands, pevhu-podzol nevhu.

Urea inofanira kutevedzerwa somunhu pre-dzichifura munguva yechirimo kurimwa, uyewo mudzi kuberekesa munguva Mwaka wokukura. The kunonyanyisa zvinogona kuitwa tichibatanidza urea mu acidic nevhu pamwe liming uye kuwedzera potashi uye phosphate fetiraiza.

Imwe mhando, kungova boka "nitrogenous fetiraiza" ndiko amoniya mvura, pasi mutengo uye nyore kuti vakabvumira kuti kupararira chaizvo mune zvokurima.

Amoniya mvura kutaurwa muvhu asati adyara muchirimo sechipiriso nechigadziko fetiraiza, uye ipapo pamukova kutanga kwekupwanyiwa tsika, kunyanya kana mukuru kudiwa senitrogen. Kuti uchengete amoniya huri mhinduro, pashure kuita mupfudze iri midzi muvhu asina asingasviki 10 masendimita.
