Apstrakt
Due to the dissolution properties the phosphate glasses can be promising materials for the development of new ecologically safe fertilizers. The complex polyphosphate glass with a molar ratio (M2O + MO)/P2O5 >1 and addition of microelements Zn2+, Mn2+, Fe3+ and Cu2+ were used in substrate for production of flower and vegetables seedlings. Dissolution tests were conducted in deionized water and 2% citric acid. The effects of the reaction time on the normalized glass mass loss (fm) and the normalized concentrations of the ions (fi) at 20, 30, 37 and 50°C were determined. Dissolution rate constants (kw - deionized water, kc -2% citric acid) were also determined (kw-0.0028-0.0094 gm-2, kc-0.029-0.011 gm-2). Values of kc were higher than those of kw, which confirms a significant effect of solvent type and temperature on the dissolution kinetics of glass. The experiments with plants (one vegetable and one flower) showed that the addition of phosphate glass caused an increase in yield and qua...lity of plants. The applied dose of polyphosphate glass of 1gl-1 showed the best effect on the growth of the examined plant seedlings.

Polifosfatno staklo, u kome je molski odnos (M2O + MO)/P2O5 >1, koje sadrži i mikroelemente Zn2+, Mn2+, Fe3+ i Cu2+, korišćeno je u supstratu za proizvodnju rasada cveća i povrća. Eksperimenti su izvedeni u stakleniku na Poljoprivrednom fakultetu u Beogradu i u laboratorijama ITNMS. Ispitivano je ponašanje polifosfatnog stakla prilikom rastvaranja u dejonizovanoj vodi i 2% rastvoru limunske kiseline na temperaturama od 20, 30, 37 i 50 °C. Ispitan je uticaj vremena rastvaranja na normalizovani gubitak mase (fm) i normalizovane koncentracije jona (fi). Određene su i konstante brzina rastvaranja(kw-dejonizovana voda, kc -2% rastvor limunske kiseline). Vrednosti kc su veće od vrednosti za kw, što potvrđuje uticaj rastvarača i temperature na proces rastvaranja. Rezultati su pokazali pozitivan efekat polifosfatnog stakla na rast i kvalitet ispitivanih biljaka. Primenjena doza polifosfatnog stakla od 1 gl-1 pokazala je najbolji efekat na rast ispitivanih biljaka-rasada.
