Qhov sib txawv tseem ceeb ntawm DAP thiab NPK chiv yog DAP chiv tsis muaj poov tshuaj thaum NPK chiv muaj poov tshuaj thiab.

Lo lus DAP yog hais txog diammonium phosphate, thiab nws yog phosphate chiv; phosphorus chiv ntau tshaj plaws hauv ntiaj teb. Yog li, peb tsim cov chiv no siv ob qho tseem ceeb hauv kev lag luam chiv; phosphoric acid thiab ammonia. NPK chiv, ntawm qhov tod tes, yog qhov tseem ceeb ntawm nitrogen, potassium thiab phosphorus. Cov no yog peb yam tseem ceeb uas cov qoob loo xav tau rau lawv txoj kev loj hlob thiab kev loj hlob.

DAP Fertilizer yog dab tsi?

DAP chiv yog qhov chaw ntawm nitrogen thiab phosphorous uas muaj kev siv dav hauv kev ua liaj ua teb. Qhov tseem ceeb ntawm cov chiv no yog diammonium phosphate uas muaj cov tshuaj formula (NH₄)₂HPO_{4Ntxiv mus, IUPAC lub npe ntawm cov tshuaj no yog diammonium hydrogen phosphate. Thiab nws yog dej-soluble ammonium phosphate.}

Nyob rau hauv cov txheej txheem ntawm cov chiv no, peb hnov phosphoric acid nrog ammonia, uas tsim cov slurry kub uas yog ces txias, granulated thiab sieved kom tau cov chiv uas peb siv tau nyob rau hauv ua liaj ua teb. Ntxiv mus, peb yuav tsum tau ua nrog cov tshuaj tiv thaiv nyob rau hauv kev tswj xyuas, vim hais tias cov tshuaj tiv thaiv siv sulfuric acid, uas yog txaus ntshai los daws. Yog li ntawd, tus txheej txheem nutrient qib ntawm cov chiv no yog 18-46-0. Qhov no txhais tau tias, nws muaj nitrogen thiab phosphorous nyob rau hauv qhov ratio ntawm 18:46, tab sis nws tsis muaj poov tshuaj.

Feem ntau, peb xav tau kwv yees li 1.5 mus rau 2 tons ntawm phosphate pob zeb, 0.4 tons ntawm sulfur (S) kom yaj cov pob zeb, thiab 0.2 tons ntawm ammonia rau kev tsim DAP. Ntxiv mus, pH ntawm cov khoom no yog 7.5 txog 8.0. Yog li ntawd, yog tias peb ntxiv cov chiv no rau hauv av, nws tuaj yeem tsim cov alkaline pH nyob ib ncig ntawm cov chiv granules uas yaj hauv av dej; yog li tus neeg siv yuav tsum tsis txhob ntxiv ntau npaum li cas ntawm cov chiv no.

NPK Fertilizer yog dab tsi?

NPK chiv yog peb yam chiv uas muaj txiaj ntsig zoo rau kev ua liaj ua teb. Cov chiv no ua raws li qhov chaw ntawm nitrogen, phosphorus thiab potassium. Yog li ntawd, nws yog ib qho tseem ceeb ntawm tag nrho peb cov khoom noj tseem ceeb uas cov nroj tsuag xav tau rau nws txoj kev loj hlob, kev loj hlob thiab kev ua haujlwm zoo. Lub npe ntawm cov khoom no kuj qhia txog cov khoom noj uas nws tuaj yeem muab tau.

NPK kev ntsuas yog kev sib xyaw ntawm cov lej uas muab qhov sib piv ntawm nitrogen, phosphorous thiab potassium muab los ntawm cov chiv no. Nws yog kev sib xyaw ntawm peb tus lej, sib cais los ntawm ob lub dashes. Piv txwv li, 10-10-10 qhia tias cov chiv muab 10% ntawm txhua qhov khoom noj. Nyob ntawd, thawj tus lej hais txog qhov feem pua ntawm nitrogen (N%), tus lej thib ob yog rau feem pua phosphorous (hauv cov qauv ntawm P ₂ O _{5 %), thiab qhov thib peb yog rau poov tshuaj feem pua (K}2_O%).

Dab tsi yog qhov txawv ntawm DAP thiab NPK Fertilizer

DAP chiv yog qhov chaw ntawm nitrogen thiab phosphorous uas muaj kev siv dav hauv kev ua liaj ua teb. Cov chiv no muaj diammonium phosphate - (NH₄)₂HPO₄Qhov no ua raws li qhov chaw ntawm nitrogen thiab phosphorus. Txawm li cas los xij, NPK chiv yog peb yam chiv uas muaj txiaj ntsig zoo rau kev ua liaj ua teb. Nws muaj nitrogenous compounds, P₂O₅ thiab K_{2O. Ntxiv mus, nws yog ib qho tseem ceeb ntawm nitrogen, phosphorous thiab poov tshuaj rau kev ua liaj ua teb.}

Cov hauv qab no qhia txog qhov sib txawv ntawm DAP thiab NPK chiv hauv daim ntawv teev npe.

Summary – DAP vs NPK Fertilizer

DAP thiab NPK yog cov chiv tseem ceeb heev. Peb siv lawv los ua cov khoom noj rau cov qoob loo hauv kev ua liaj ua teb. Qhov sib txawv tseem ceeb ntawm DAP thiab NPK chiv yog tias DAP chiv tsis muaj poov tshuaj thaum NPK chiv muaj cov poov tshuaj ib yam nkaus.
