The main goal of agricultural production should be the production of a sufficient amount of
agricultural products with the least possible impact on the environment. In traditional agricultural
production, to obtain a satisfactory yield, artificial fertilizers are used, which have multiple negative
impacts on the environment. Glassy fertilizers are a type of fertilizer that, at least according to
previous research, do not have a negative impact on the environment, and at the same time the use of
these fertilizers yields no less than when using traditional fertilizers. Glassy fertilizers are fertilizers
with controlled dissolution, they do not pollute groundwater or surface water, and the pH of the soil
does not change with their use, by changing the composition they can adapt to the requirements of
each crop individually, etc. The paper presents three phosphate glassy fertilizers of different chemical
compositions, obtained at the Centre for Inorganic Technologies, ITNMS. The method of obtaining
glassy fertilizers, their dissolution rates in a medium that simulates soil conditions, the changes in pH
values of solutions for different dissolution times, and the effect of temperature on dissolution rates
are shown. Also, the results of the influence of glass fertilizers on plant cultures in real conditions are
presented.
