Detalji:<\/h3>\n

Tlo, zemlja mo\u017ee biti kisela, neutralna ili alkalna, ovisno o pH vrijednosti. Ve\u0107ina biljaka preferira pH raspon od 5,5 do 7,5; ali neke vrste vi\u0161e vole kiselinska ili alkalna tla. Ipak, svaka biljka zahtijeva odre\u0111eni raspon pH za optimalan rast.<\/p>\n

pH zna\u010dajno utje\u010de na dostupnost hranjivih tvari i prisutnost mikroorganizama i biljaka u tlu, zemlji. Na primjer, gljivice preferiraju kisele uslove, dok ve\u0107ina bakterija, posebno onih koje opskrbljuju biljke hranjivim tvarima, preferiraju umjereno kisela ili blago alkalna tla, zemlju. Zapravo, u jako kiselim uslovima smanjuje se fiksiranje du\u0161ika i mineralizacija biljnog ostatka. Biljke apsorbiraju hranjive tvari otopljene u vodi u tlu, zemlji, a topljivost hranjivih tvari uvelike ovisi o pH vrijednosti. Dakle, dostupnost elemenata je razli\u010dita pri razli\u010ditim razinama pH.<\/p>\n

Svaka biljka treba elemente u razli\u010ditim koli\u010dinama i to je razlog za\u0161to svaka biljka zahtijeva odre\u0111eni raspon pH kako bi optimizirala svoj rast. Na primjer, \u017eeljezo, bakar i mangan nisu topljivi u alkalnoj okolini. To zna\u010di da bi biljke koje trebaju ove elemente teoretski trebale biti u kiselom tipu tla, zemlje. Du\u0161ik, fosfor, kalij i sumpor, s druge strane, lako su dostupni u rasponu pH blizu neutralnosti. Nadalje, abnormalne pH vrijednosti pove\u0107avaju koncentraciju toksi\u010dnih elemenata za biljke. Na primjer, u kiselim uslovima mo\u017ee postojati vi\u0161ak aluminijevih iona u takvim koli\u010dinama koje biljka ne mo\u017ee podnijeti. Negativni u\u010dinci na hemijsku i fizi\u010dku strukturu tako\u0111e su prisutni kada su pH vrijednosti predaleko od neutralnih uslova (razbijanje agregata, manje propusna i kompaktnija zemlja).<\/p>\n

Mjera\u010d HI99121 ima veliki LCD display visoke razine koji prikazuje i o\u010ditanja pH i temperature istovremeno s 0,01 pH rezolucije i ta\u010dnosti od \u00b1 0,05 pH.<\/p>\n

LCD display tako\u0111er ima indikatore za status i stabilnost kalibracije, kao i poruke o uputama na display-u.<\/p>\n

HI99121 ima mnoge napredne zna\u010dajke koje se nalaze u skupljim prijenosnim instrumentima, uklju\u010duju\u0107i automatsku kalibraciju, prepoznavanje me\u0111uspremnika i temperaturnu kompenzaciju. Razina postotka baterije prikazana je pri pokretanju kao i upozorenja za korisnika na preostalu dostupnu bateriju.<\/p>\n

Isporu\u010dena HI1292D predpoja\u010dana elektroda ima stakleno tijelo te ugra\u0111eni temperaturni senzor koji je posebno dizajniranim za mjerenje pH u zemlji.<\/p>\n
