Currently, year by year the industrial waste stockpiles increase, but at the same time its recycling is not more than 10–15% of the production. There are several methods of recycling of such waste as phosphogypsum and ash, among which one of the perspective directions is considered using them in agriculture as fertilizer and ameliorator. The limiting factor of their widespread use in agriculture is the presence of heavy metals and radionuclides in them. This article presents data about environmental safety of using phosphogypsum and ash for cultivation spring wheat on the chernozem soils of Northern Kazakhstan. According to the results of research, using phosphogypsum and ash doesn’t give negative impact on the environment, the presence of heavy metals and radionuclides in the soil and grain do not exceed the maximum allowable concentrations.
