\n\t\t\t\t\t\t\t\t\tMerenje TDS-a je dug proces. Prvo izvu\u010dete svu vodu iz uzorka tla, zatim isparite vodu i izmerite preostali ostatak nakon isparavanja. Mnogo je lak\u0161e izmeriti elektri\u010dnu provodljivost supstance, a zatim pretvoriti o\u010ditavanje u TDS sa faktorom konverzije. Trik je da se uverite da koristite ispravan faktor konverzije!\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tNe\u0161to \u0161to treba imati na umu kada birate faktor konverzije je da sve rastvorene \u010dvrste materije ne provode elektri\u010dnu energiju. Na primer, ako ste izmerili provodljivost \u010da\u0161e vode, a zatim dodali kuhinjsku so, provodljivost c\u0301e porasti. Ali, ako uzmete tu istu \u0161olju vode, izmerite provodljivost, a zatim dodate \u0161ec\u0301er, provodljivost ne bi bila pogo\u0111ena.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t
\n\t\t\t
\n\t\t\t\t\t\t
\n\t\t\t\t\t\t\t\t\tTo je zato \u0161to se kuhinjska so raspada na naelektrisane jone kada se stavi u rastvor. \u0160ec\u0301er se rastvara, ali se ne raspada na naelektrisane jone. Me\u0111utim, ako biste izmerili TDS dve \u010da\u0161e vode, na njih bi uticalo dodavanje soli ili \u0161ec\u0301era.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\tNaj\u010de\u0161c\u0301i faktori konverzije izme\u0111u EC i TDS su 0,5 i 0,7. Faktor konverzije 0,5 je zasnovan na tome kako se EC i TDS odnose na natrijum hlorid. Faktor konverzije 0,7 zasniva se na tome kako se EC i TDS odnose na me\u0161avinu natrijum sulfata, natrijum bikarbonata i natrijum hlorida. Da biste koristili faktor konverzije, jednostavno pomno\u017eite svoje EC o\u010ditavanje sa faktorom konverzije da biste izra\u010dunali TDS.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tTestiranje va\u0161eg tla je sve u tome da se uverite da su hranljivi sastojci izbalansirani. Merenje pH vrednosti zemlji\u0161ta daje vam predstavu o tome koliko su hranljivi sastojci dostupni, dok vam EC ukazuje na to koliko ih zapravo ima. Zapamtite da je EC dobar u merenju ja\u010dine jona u zemlji\u0161tu. Ovo vam poma\u017ee da pratite hranljive materije koje su dostupne va\u0161im biljkama.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
