Taurin ruwa shine haɗuwa da sinadarai da kaddarorin jiki masu alaƙa da abun ciki na narkar da gishirin ƙarfe na ƙasa na alkaline, galibin calcium da magnesium, abin da ake kira “taurin gishiri”.
Ruwa mai dauke da 100-150 MG na alli a kowace lita yana da karɓa don amfani da hydroponic kuma, bisa ga ka’ida, ga yawancin tsire-tsire, ba lallai ba ne don ƙara ƙarin calcium.
Ruwa mai laushi ya ƙunshi ƙasa da 50 MG na calcium kowace lita. Don samun nasarar ci gaban shuka, ya zama dole a bugu da žari ƙara alli da gishirin magnesium.
Masu kera takin hydroponic suna la’akari da kasancewar calcium da magnesium a cikin tsarin su kuma suna samar da nau’ikan takin mai magani na ruwa mai ƙarfi da taushi.
An bambanta taurin ruwa tsakanin wucin gadi (carbonate) da dindindin.
Taurin ruwa na wucin gadi
Tauri na ɗan lokaci wani nau’in taurin ruwa ne wanda ke haifar da kasancewar narkar da calcium carbonate da magnesium carbonate. Lokacin da waɗannan ma’adanai suka narke a cikin bayani, ƙwayoyin calcium da magnesium cations (Ca2+, Mg2+) da kuma carbonate da bicarbonate anions32-HCO3,). Mafi kyawun pH don hydroponics shine 5,5. pH na ruwa zai yi yawa idan ruwan ban ruwa ya ƙunshi adadi mai yawa na carbonate da bicarbonate (CO).32-HCO3,). Yawancin lokaci wannan yana faruwa lokacin amfani da ruwan rijiya. Don haka, dole ne a bi da wannan ruwa tare da acid don kawar da HCO.3, da rage pH na maganin gina jiki. Adadin acid ɗin da za a ƙara an ƙaddara ta abun cikin HCO3,… Lokacin da aka ƙara acid a cikin ruwa, bicarbonate ɗin yana raguwa ta hanyar proton na acid kuma pH na maganin zai ragu. Calcium (ko magnesium) zai kasance yana samuwa don shayar da tsire-tsire kuma anion acid zai ci gaba da narkar da shi a cikin ruwa. Alal misali, ƙara nitric acid zai haifar da amsa mai zuwa:
Ca2+ + 2 HCO3, + 2 HNO3 ⇋ Ca2+ + 2 KU2 + 2H2O + 2 NO3,
Nitric acid ana amfani da shi sosai don wannan dalili, amma ana iya amfani da acid phosphoric da abubuwan da suka samo asali, kamar urea phosphate. Ta hanyar ƙara yawan acid, za ku ƙara yawan abubuwan anions masu alaƙa a cikin bayani, kamar nitrate da phosphate. Wadannan dabi’un kada su wuce abin da ake bukata don maganin gina jiki. Wannan yana iyakance adadin acid wanda za’a iya ƙarawa don kawar da HCO.3… Saboda haka, na farko taro na HCO3, a cikin ruwa babbar matsala ce mai inganci.
Neutralization na bicarbonate tare da acid yana fara juyin halittar carbon dioxide (CO2) da ruwa. CO2 dole ne a bar mafita na gina jiki da yardar kaina; in ba haka ba, pH na maganin ba zai sauke ba kuma zai canza. Wannan yana nufin cewa acid da bicarbonate dauki dole ne su faru a cikin buɗaɗɗen tsarin, kamar buɗaɗɗen tanki.
