Ib zaug, xyoo 1669, ib tus kws kho mob alchemist H. Brandt tau ua qhov kev sim hauv qab no: nws evaporated cov zis kom qhuav, sib tov cov hmoov av nrog xuab zeb thiab thee, thiab tom qab ntawd muab cov dej sib tov sib xyaw rau hauv qhov kaw retort. Yog li ntawd, nws tau txais ib yam khoom uas muaj tej yam yees siv uas ci ntsa iab hauv qhov tsaus ntuj. Qhov no yog li cas phosphorus tau thawj zaug. Ntau tshaj li peb puas xyoo dhau los txij thaum ntawd los, tam sim no cov tshuaj no tau siv dav hauv ntau yam lag luam, nrog rau kev ua liaj ua teb. Cia peb tham txog qhov kev siv ntawm superphosphate tuaj yeem muab rau hauv tsev rau lub caij ntuj sov thiab yuav ua li cas nws ntau yam txawv ntawm ib leeg. Peb vam tias tsab xov xwm no yuav qhia tau zoo rau txhua tus neeg uas cog qoob loo hauv lawv lub vaj.

Fertilizer with the prefix "super"

Qhov nrov ntawm cov tshuaj no yog vim qhov tseeb tias, thawj zaug, nws tsis muaj tshuaj lom, tiv taus hluav taws thiab tawg, thiab qhov thib ob, nws tsim nyog rau yuav luag txhua hom av. Kev siv cov superphosphatetso cai rau koj kom tau txais txiaj ntsig zoo ntawm pob kws, beets, qos yaj ywm, flax, zaub, cereals thiab lwm yam qoob loo. Ntxiv mus, cov kws tshaj lij pom zoo kom tau txais txiaj ntsig zoo los ua ke nrog kev siv cov tshuaj no ua ib feem ntawm kev hnav khaub ncaws sab saum toj nrog kev sib ntxiv ntawm ib qho me me rau lub qhov lossis kab tam sim ua ntej sowing. Los ntawm lub sij hawm no, tej zaum koj twb muaj lus nug txog yuav ua li cas npaum li cas cov chiv no yuav tsum tau siv. Nco ntsoov tias kev siv superphosphate ncaj qha nyob ntawm theem ntawm cov av fertility, kev siv cov organic additives thiab cov qoob loo loj hlob. Tsis tas li ntawd, hom chiv siv yuav tsum raug coj mus rau hauv tus account. Piv txwv li, rau cov qoob loo zaub, qhov nruab nrab koob yog 40-60 (thaum muaj ib qho yooj yim) los yog 20-30 grams ib 1 m2 (yog tias koj npaj yuav siv ob npaug superphosphate).

Kev siv cov chiv no tau pom zoo nyob rau hauv thaj chaw uas cov txiaj ntsig tau nyob ntawm cov ntsiab lus ntawm cov sulfur hauv cov av, uas ua lub luag haujlwm tseem ceeb hauv kev cog qoob loo ntawm oilseeds, cereals thiab legumes. Nws yog qhov zoo dua los siv superphosphate nyob rau hauv kab - qhov no, phosphorus siv tus nqi yog ob peb zaug siab dua li thaum thov random ua ntej plowing. Nyob rau tib lub sijhawm, cov chiv no yuav tsum tsis txhob raug tsim txom. Tshwj xeeb tshaj yog tias peb xav txog tias hauv 2-3 xyoos kev nqus coefficient ntawm phosphorus hauv superphosphate yog kwv yees li 40%.

Kev sib xyaw thiab ntau yam

Ntxiv rau nws cov khoom tseem ceeb, cov chiv no tseem muaj nitrogen, sulfur,magnesium thiab calcium. Nyob ntawm qhov feem pua ntawm phosphorus absorbed los ntawm cov qoob loo ua liaj ua teb, superphosphate tuaj yeem yooj yim, ob npaug thiab ntxiv. Lub tom kawg nyob rau hauv nws muaj pes tsawg leeg occupies ib tug nruab nrab txoj hauj lwm ntawm thawj ob. Niaj hnub no, cov chiv no tuaj yeem yuav ob qho tib si hauv hmoov thiab granular daim ntawv. Hauv thawj kis, kev siv superphosphate yuav raug nqi rau cov neeg siv khoom pheej yig dua. Vim nws yooj yim sib tov, hom chiv no yog qhov zoo tshaj plaws rau composting. Ntawm qhov tod tes, kev npaj hmoov hauv qee qhov xwm txheej coj cov txiaj ntsig tsawg dua li granular superphosphate. Kev siv tom kawg tsis txhob caking, tswj kom zoo dispersion, thiab nws muaj phosphorus ntau (txog 22%).
