Evaluation reveals fertilization from bioconverted sewage sludge enhances soil properties and yields without heavy metal contamination.
The evaluation of compost and biocompost based on sewage sludge (SS) produced by various methods as fertilizer for spring grain crops showed that the use of fertilizers in the first year of operation improved the acid-base properties of the soil, increased the content of mineral nitrogen and mobile phosphorus in the arable soil layer. The standardized application of compost and biocompost based on organic fertilizers ensured reliable yield increases and did not lead to contamination of soil and grain with heavy metals.
