Assessment of the possibilities of using phosphogypsum to increase the stability of lawn ecosystems under conditions of salinization with deicing reagents

The article presents the results of a laboratory experiment to determine the effect of various doses of phosphogypsum on the condition and stability of lawn ecosystems, including biomass, height and projective covering of grass mixtures under conditions of application of solutions of deicing reagents. The results of the study showed that relatively low doses of phosphogypsum in peat-sandy soil (1 g / kg of soil D.V. P2O5 in terms) with increased doses of deicing reagents contribute to the preservation of the viability of the herbage. Relatively high doses of phosphogypsum (4 g/kg) at the same time show lower results (the lowest biomass index at the end of the experiment is 4.4 g/m2).
