Soil remediation from cooper and grass vegetation in contaminated soil

Abstract

Chloride and calcium are essential elements for plants. Conifers also use sodium in their metabolism. In greater amounts, however, especially sodium and chloride are toxic to plants. The aim of investigation is to determine which of the analyzed herbaceous vegetation species (perennial ryegrass, fescue grass, meadow-grass) shows the highest degree of resistance to toxic impact of salts (stress), to set the toxic limits of salt concentrations, and to analyze how salts impact on the core parameters of herbaceous vegetation. The research findings show that technical NaCl contained in soil has the adverse effect on the growth dynamics of grass vegetation i.e. slows down the increase of the above-ground part and reduces the phytomass. The experiments have proved that is the perennial ryegrass that shows the most rapid germination, the most rapid growth and the highest resistance to the toxic effect of salt.
