PROSPECTS FOR THE USE OF RECYCLED SEWAGE SLUDGE IN AGRICULTURE

The article is devoted to the systematization of research results on the use of sewage sludge in agriculture and afforestation. The expediency of such systematization is due to the fact that the annual accumulation of sewage sludge in the world is estimated at 200 billion tons with an average humidity of 96%, and studies of the effect of sewage sludge after disposal on agricultural land and forest lands, especially those intended for reforestation, are insufficient. The author studied the environmental indicators taken into account when using sewage sludge as soils for reclamation and biofertilizers for land reclamation and concluded that the fertilizers obtained can provide increased soil fertility and restoration of fire-affected land plots.
