Glasses are ecological materials able to incorporate different oxides such as MoO3, B2O3, V2O5, and Fe2O3 in their composition, useful for plant growth [1-3]. The paper presents a study on glassy fertilizers based on phosphate glass doped with 1-7 mol % MoO3, B2O3, V2O5, and Fe2O3, respectively.. Glasses were prepared by melting the raw materials at 1100 - 1200 oC for 2h using ceramic crucibles put in electric furnaces. The glasses structure and properties were analyzed. The solubility in water was determined on glass powders by using three methods: i) boiling for 1 h, ii) solubility after 21 days at room temperature and iii) by measuring the dependency of the solution conductivity on time. In order to establish the vitreous fertilizers solubility, the conductometry method was used. Glass structure was analyzed by FTIR (range 400 - 4000 cm-1) and Raman spectroscopy (range 100 - 4000 cm-1) revealing specific maxima [4-7] for P-O stretching and bending vibrations mode and the network former role of phosphorous pentoxide.
