Qhov sib txawv tseem ceeb ntawm nitrogen thiab phosphorus chiv yog nitrogen chiv yog tsim los ntawm ammonia, whereas phosphorous chiv yog tsim los ntawm phosphate pob zeb.
Fertilizers yog cov khoom siv los ntawm ntuj los yog hluavtaws thiab, thaum siv rau hauv av lossis cog cov ntaub so ntswg, tuaj yeem muab cov khoom noj rau cov nroj tsuag. Peb tuaj yeem txheeb xyuas lawv qhov txawv ntawm cov ntaub ntawv liming thiab lwm yam tsis muaj kev hloov kho av. Muaj ntau qhov chaw ntawm chiv. Niaj hnub no, peb lub ntsiab macronutrients tseem ceeb rau cov nroj tsuag muaj xws li nitrogen, phosphorus, thiab poov tshuaj, sau npe NPK. Qee lub sij hawm, peb yuav tsum ntxiv cov hmoov av pob zeb ua cov micronutrient thiab. Daim ntawv thov ntawm cov chiv kuj tuaj yeem sib txawv ntawm ib qho mus rau lwm qhov, xws li. pelletized los yog kua daim ntawv thov, siv cov khoom ua liaj ua teb loj lossis cov cuab yeej siv tes, thiab lwm yam.
Nitrogen Fertilizer yog dab tsi?
Nitrogen chiv tuaj yeem piav qhia raws li cov ntsiab lus nitrogen loj rau cov qoob loo uas tsis yog cov nplej nplej. Peb tuaj yeem ua hom chiv no los ntawm ammonia. Cov txheej txheem uas peb siv rau qhov kev tsim khoom no yog txheej txheem Haber-Bosch. Feem ntau, cov txheej txheem no yog cov txheej txheem siv hluav taws xob ntau qhov uas cov pa roj ntsha feem ntau muab hydrogen thiab nitrogen tau los ntawm huab cua. Peb tuaj yeem siv ammonia los ua khoom noj rau txhua hom nitrogen chiv, suav nrog anhydrous ammonium nitrate thiab urea.

Ntxiv mus, peb tuaj yeem pom cov khoom tso ntawm sodium nitrate (ib hom chiv nitrogen) hauv cov suab puam Atacama hauv Chile. Nws tsuas yog nitrogen-nplua nuj chiv tam sim no thaum ntxov. Txawm li cas los xij, tib neeg tseem mine cov deposits rau chiv. Ntxiv mus, peb tuaj yeem tsim cov nitrates los ntawm ammonia los ntawm cov txheej txheem Ostwald.
Y Phosphorous Fertilizer yog dab tsi?
Phosphorous chiv tuaj yeem piav qhia tias yog cov khoom siv phosphorous loj rau cov qoob loo hauv kev ua liaj ua teb. Peb tuaj yeem yooj yim tau phosphorous chiv los ntawm kev rho tawm ntawm pob zeb phosphate. Muaj ob yam tseem ceeb ntawm phosphorous hauv pob zeb no, uas suav nrog fluorapatite thiab hydroxyapatite. Ob cov zaub mov no tuaj yeem hloov mus rau hauv dej-soluble phosphate ntsev los ntawm kev kho cov khoom hauv sulfuric acid lossis phosphoric acid.
Daim duab 02: Phosphate Rock
Kev rho tawm ntawm phosphorous chiv los ntawm phosphate pob zeb yog ib qho kev cuam tshuam loj hauv kev loj hlob ntawm sulfuric acid txhua xyoo. Thaum lub sij hawm Odda txheej txheem los yog cov txheej txheem nitro-phosphate, phosphate pob zeb uas muaj txog li 20% phosphorous yog yaj nyob rau hauv nitric acid rau zus tau tej cov sib tov ntawm phosphoric acid thiab calcium nitrate. Peb tuaj yeem muab cov tshuaj no sib xyaw nrog cov poov tshuaj chiv txhawm rau tsim cov chiv sib xyaw uas muaj peb qhov macronutrients, suav nrog N, P, thiab K, rau hauv daim ntawv yooj yim yaj.
Qhov txawv ntawm Nitrogen thiab Phosphorus Fertilizer yog dab tsi?
Fertilizers yog cov khoom siv los ntawm ntuj los yog hluavtaws uas, thaum siv rau hauv av lossis cog cov ntaub so ntswg, tuaj yeem muab cov khoom noj rau cov nroj tsuag. Nitrogen chiv yog cov khoom siv nitrogen loj rau cov qoob loo uas tsis yog cov qoob loo qoob loo, thaum phosphorous chiv yog cov khoom siv phosphorous loj rau cov qoob loo hauv kev ua liaj ua teb. Qhov sib txawv tseem ceeb ntawm nitrogen thiab phosphorous chiv yog nitrogen chiv yog tsim los ntawm ammonia, whereas phosphorous chiv yog tsim los ntawm phosphate pob zeb.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm nitrogen thiab phosphorous chiv.
Summary – Nitrogen vs Phosphorus Fertilizer
Nitrogen chiv yog cov khoom siv nitrogen loj rau cov qoob loo qoob loo uas tsis yog cov noob qoob loo. Phosphorous fertilizer yog cov khoom siv phosphorous loj rau cov qoob loo hauv kev ua liaj ua teb. Qhov sib txawv tseem ceeb ntawm nitrogen thiab phosphorous chiv yog nitrogen chiv yog tsim los ntawm ammonia, whereas phosphorous chiv yog tsim los ntawm phosphate pob zeb.
