ABSTRACT

In the results of field experiments we established that the use of fertilizers based on sewage sludge when optimizing their doses ensures sustainable productivity of agrocenoses of perennial grasses and fiber flax, increases the fertility of sod-podzolic soils, their biological activity, preserves biodiversity, does not cause heavy metal accumulation in soil and plant production.
