AB  - 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  gt 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 quality of plants. The applied dose of polyphosphate glass of 1gl-1 showed the best effect on the growth of the examined plant seedlings.
AB  - Polifosfatno staklo, u kome je molski odnos (M2O + MO)/P2O5  gt 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.

AB  - This paper investigates the possibility and justification of controlled release glass application as a new ecological material in the production of plants-seedlings of French marigold (Tagetes patula L.). During the investigation its influence on the development of the produced plants-seedlings was monitored. The seedlings were produced in poly-propylene containers (speedling system) and poly-propylene pots (pot system). The trial was conducted in the greenhouse at the Faculty of Agriculture in Belgrade during 2011. In the course of seedling production the glass granulation of  lt  0.5 mm was added in the following doses: 0, 1, 2, 3, and 4 g/l. The results of the research show a positive effect of controlled release glass application in the production of French marigold seedlings, since high quality seedlings were produced justifying its application. The best effect on the analyzed parameters of plant-seedling development was found when substrate was applied in the dose of 1 g/l.
AB  - U radu je ispitivana mogućnost i opravdanost primene stakla sa kontrolisanim otpuštanjem hranljivih elemenata kao novog ekološkog materijala u proizvodnji biljaka-rasada kadifice (Tagetes patula L.). Tokom istraživanja praćen je njegov uticaj na razvijenost proizvedenih biljaka-rasada. Biljke-rasada proizvedene su u polistirenskim kontejnerima (speedling system) i polipropilenskim saksijama (pot system). Istraživanja su sprovedena u stakleniku Poljoprivrednog fakulteta u Beogradu tokom 2011. U toku proizvodnje rasada dodavano je ispitivano staklo granulacije  lt  0,5 mm u dozama 0-4 g/l. Rezultati istraživanja ukazuju na pozitivan efekat primenjenog stakla sa kontrolisanim otpuštanjem jona u proizvodnji biljaka-rasada kadifice. Njegovom primenom dobija se rasad bolje razvijenosti, te je njegova upotreba opravdana. Najbolji efekat na ispitivane parametre razvijenosti biljaka-rasada imala je doza od 1 g/l supstrata.
