Comparison of the phytotoxic effect of elemental sulfur and potassium sulfate

In this work considered comparative phytotoxic effect of elemental sulfur and sodium sulfate to the test-cultures oat (Avena sativa L.) and Lupinus angustifolius (Lupinus angustifolius L.). Methodical recommendations "justify the hazard class of waste production and consumption of phytotoxicity" were taken as a basis of the research methods. Toxicant dose range ranged between 1 and 5 MPC (calculated as sulfur). It is shown that in the range of concentrations studied, potassium sulfate has minimal toxic effect, compared with elemental sulfur. Also, depending on the culture, may cause the activating and inhibitory growth properties.
