Synthetic Ammonium Sulfate yog nitrogen-sulfur chiv uas muaj 24% sulfur thiab 21% nitrogen. Outwardly, nws zoo li ib tug dawb crystalline ntsev, uas dissolves zoo nyob rau hauv dej thiab yog chemically nruab nrab. Ammonium sulfate muaj ib tug tsis muaj zog hygroscopicity thiab thaum lub sij hawm ntev cia nws tsis ncuav mog qab zib, thaum tuav flowability. Thiab tus nqi ntawm cov tshuaj muaj nyob rau hauv nws yog ib qho nyuaj rau overestimate. Cov nitrogen tib yam muaj feem cuam tshuam rau kev ua haujlwm tseem ceeb ntawm cov nroj tsuag. Nws yog rightfully suav hais tias yog tus thawj coj ntawm cov ntxhia chiv. Thiab leej faj hais txog qhov tseem ceeb hauv cov zaub mov cog tuaj yeem muab qhov chaw thib peb, txij li phosphorus nyob qhov thib ob.

Ammonium sulfate yog cov chiv uas muaj txiaj ntsig zoo rau txhua hom qoob loo. Thaum ua ntawv thov, nws dissolves nyob rau hauv dej tsis muaj teeb meem, thiab ces nws yog zoo absorbed los ntawm cov nroj tsuag. Tsis tas li ntawd, nws tsis muaj zog thiab txawm tias muaj dej noo siab nws tsis raug ntxuav tawm ntawm cov av. Thiab qhov ua tau zoo ntawm cov chiv no tsis qis dua li ntawm urea thiab ammoniantsev. Tab sis yog tias peb xav txog qee yam ntawm nws lub cev thiab tshuaj lom neeg (incombustibility, kev nyab xeeb tawg, tsis-caking) thiab tus nqi, ces ammonium sulfate yuav muaj txiaj ntsig ntau dua li nws "cov neeg sib tw". Tsis tas li ntawd ib qho tseem ceeb ntawm cov chiv no yog sulfur, uas ua lub luag haujlwm tseem ceeb hauv lub neej ntawm cov nroj tsuag. Nws yog ib feem ntawm cov proteins thiab cov amino acids tseem ceeb xws li methionine thiab cystine. Nws kuj muaj nyob rau hauv cov vitamins thiab roj.

Nyob rau hauv qhov no, ammonium sulfate muaj qhov zoo ntawm cov txheej txheem redox tshwm sim hauv cov nroj tsuag, nrog rau kev ua kom cov enzymes thiab cov metabolism hauv cov protein, thawj cov khoom lag luam rau kev sib txuas uas tsuas yog oxidized daim ntawv ntawm leej faj.. Thiab yog hais tias nws tsis txaus, ces cov synthesis ntawm cov protein yog ncua, thiab thiaj li hu ua sulfur starvation pib nyob rau hauv cov nroj tsuag, uas nyob rau hauv nws cov yam ntxwv zoo li nitrogen starvation. Nyob rau tib lub sijhawm, cov qoob loo ua liaj ua teb raug ncua hauv kev loj hlob, lawv cov stems lengthen thiab nplooj poob. Muaj tseeb, tom kawg tsis tuag tawm, tab sis noj cov xim daj ntseg. Thiab raws li kev tshawb fawb tau pom, nws yog sulfur deficiency uas ua rau muaj kev ua txhaum ntawm nitrogen metabolism. Thiab koj tuaj yeem zam tau yog tias koj ntxiv ammonium sulfate. Fertilizer qhov no yuav pab kho qhov tsis muaj leej faj.

Cov neeg ua liaj ua teb kuj paub tias kev siv cov chiv nitrogen ntau dhau tuaj yeem ua rau muaj teeb meem ib puag ncig, tshwj xeeb tshaj yog tias lawv tsis muaj cov as-ham. Nws tuaj yeem ua rau muaj kuab paug ntawm cov dej hauv av thiab hauv av, pov tseg ntawm cov khoom. Kuj tseem nyob hauv urea thiab nitratechiv, muaj qhov poob loj ntawm nitrogen (txog 30%), uas tshwm sim vim leaching thiab denitrification. Thiab ammonium sulfate poob tsis pub ntau tshaj 3% ntawm cov roj teeb no. Nws yuav tsum tau muab sau tseg tias nitrogen yog nyob rau hauv nws nyob rau hauv lub feem ntau yooj yim daim ntawv rau cov nroj tsuag, thiab nws koom nyob rau hauv tsim ntawm cov qoob loo thoob plaws lub caij loj hlob.

Tsis tas li, ammonium sulfate yog siv los rov siv cov quav cab. Thaum ua li ntawd, nws hloov mus ua chiv. Ntawd yog, nws yog siv rau hauv av nrog rau cov qoob loo seem ntawm ib koob ntawm 10 kilograms ib tuj straw. Nyob rau tib lub sijhawm, nws pab txhawb kom nrawm nrawm ntawm fiber ntau. Hauv qhov no, ntau qhov teeb meem raug daws nyob rau tib lub sijhawm - cov av tau txais cov chiv ntxiv, straw yog siv thiab kev tiv thaiv ib puag ncig. Thiab yog tias cov qoob loo sau qoob loo yog 20-30 centners ib hectare, ces ammonium sulfate, nrog rau cov quav cab tom qab lawv, muaj peev xwm rov qab mus txog 40 kg ntawm nitrogen, 18-24 kilograms ntawm poov tshuaj, mus txog 80 kg ntawm phosphorus thiab 35-45 kg ntawm sulfur rau hauv av, uas nce feem pua ntawm cov protein ntau hauv cov khoom.
