Xam cov nqi Fertilizer Raws li cov khoom noj uas muaj ntau dua li Nitrogen

Qee zaum, kev kuaj av yuav qhia txog qhov tsis txaus ntawm cov khoom noj tshwj xeeb thiab pom zoo kom siv cov khoom noj ntawd ntawm tus nqi tshwj xeeb. Piv txwv li, kev ntsuam xyuas av qhia tias qhov tsis txaus ntawm cov poov tshuaj, tab sis lwm cov as-ham tsis xav tau. Cov chiv zoo li potassium sulfate (0-0-50) tuaj yeem siv los muab cov poov tshuaj, tab sis nws yuav tsis muab lwm cov as-ham zoo li nitrogen (uas tsis yog teeb meem vim tsis xav tau nitrogen ntxiv). Hauv qhov xwm txheej no, nitrogen tsis tuaj yeem siv los ua lub hauv paus ntawm kev suav, raws li nws feem ntau yog.

Lwm lub sij hawm, cov khoom noj yuav xav tau nyob rau theem uas qhov piv ntawm cov khoom noj rau nitrogen tsis tuaj yeem pom hauv cov chiv. Piv txwv li, kev ntsuam xyuas av qhia qhov xav tau nitrogen ntawm tus nqi ntawm 0.15 lbs ntawm N ib 100 ft.²thiab potassium ntawm tus nqi ntawm 0.15 lbs ntawm K₂O rau 100 ft²(tus piv ntawm 1-0-1), tab sis qhia tau hais tias phosphorous nyob rau theem siab thiab yuav tsum tsis txhob ntxiv. Txawm li cas los xij, tsis muaj cov chiv muaj rau koj muaj qhov piv ntawm 1-0-1. Hauv qhov xwm txheej no, siv ob qho chiv sib txawv - ib qho los muab cov nitrogen (xws li sulfur-coated urea, 36-0-0) thiab ib qho los muab cov poov tshuaj (xws li potassium sulfate, 0-0-50). Ob qhov kev suav yuav tsum tau ua, ib qho rau txhua qhov chiv.

Kev suav ua raws li Phosphorous thiab Potassium

Thawj kauj ruam los xam tus nqi chiv raws li phosphorous lossis potassium yog los txiav txim seb qhov kev pom zoo yog muab rau hauv phaus phosphate lossis potash ib 100 ft.²los yog 1,000 ft², los yog nws muab raws li qhov tseeb P lossis K ib 100 ft²los yog 1,000 ft².

Kev Pom Zoo Qhia Txog Tus Nqi Phosphate lossis Potash

Yog hais tias muab nyob rau hauv cov nqe lus ntawm phosphate los yog potash ib 100 ft²los yog 1,000 ft², ces cov kev xam yuav zoo ib yam li cov kauj ruam uas tau piav saum toj no. Nrhiav qhov feem pua ntawm phosphate (tus lej thib ob hauv kev tshuaj xyuas chiv) lossis feem pua ntawm cov potash (tus lej thib peb hauv kev tshuaj ntsuam) thiab taug kev los ntawm txhua plaub kauj ruam saum toj no txhawm rau txiav txim siab cov chiv siv tau zoo.

Kev Pom Zoo Qhia Txog Tus Nqi Ntawm Phosphorous (P) lossis Potassium (K)

Yog tias qhov kev pom zoo tau muab rau hauv cov ntsiab lus ntawm phosphorous (P) lossis potassium (K), tom qab ntawd ntxiv cov kauj ruam ntxiv rau kev suav. Kev txheeb xyuas chiv qhia koj qhov feem pua ntawm phosphate (P₂O₅thiab potash (K₂O) nyob rau hauv lub hnab, tab sis cov no tsis sib npaug rau tus nqi ntawm P los yog K tiag tiag.

Hloov ua lwm yam phosphate (P₂O₅) rau elemental P, muab cov feem pua ntawm phosphate (raws li qhia los ntawm tus lej thib ob hauv kev tshuaj xyuas) los ntawm 0.44. Hloov ua lwm yam potash (K₂O) rau elemental K, muab cov feem pua ntawm cov potash (raws li qhia los ntawm tus lej thib peb hauv kev tshuaj ntsuam) los ntawm 0.83.

Piv txwv li, qhov kev pom zoo hu rau 0.10 lbs ntawm K (tsis yog K₂O) rau 100 ft². Thaum xam cov chiv uas yuav tsum tau siv 0-0-22 chiv, thawj zaug muab cov feem pua ntawm cov potash (tus lej thib peb hauv kev txheeb xyuas) los ntawm 0.83 kom tau txais qhov feem pua ntawm cov ntsiab lus K hauv lub hnab. Ces faib tus nqi los ntawm tus lej ntawd. Yog li kev suav yuav yog: 0.10 ÷ [0.22 × 0.83]=0.55. Yog li txhawm rau thov ntawm tus nqi no, koj yuav tsum tau thov 0.55 phaus ntawm 0-0-22 chiv tshaj 100 ft².

Muab xam raws li lwm cov khoom noj

Zuag qhia tag nrho, cov kauj ruam rau kev suav cov chiv raws li cov khoom noj uas tsis yog nitrogen, xws li calcium, boron, lossis manganese, yuav zoo ib yam li tau piav qhia saum toj no.
