organic amendments
The application of organic amendments to the soil is of crucial importance.
In general, it is recommended to apply stabilized and sanitized organic products to reduce potential risks associated with the use of raw organic matter, such as nitrogen immobilization, the release of phytotoxic compounds, the presence of pathogenic microorganisms, weed seeds, etc. Additionally, organic amendments and fertilizers should contain levels of heavy metals below the maximum limits allowed by current regulations.
