ORGANIC AMENDMENTS
The application of organic soil amendments is a crucial aspect. In general, it is advisable to apply stabilized and sanitized organic products to reduce potential risks arising from the application of raw organic matter, such as nitrogen immobilization, the release of phytotoxic compounds, the presence of pathogenic microorganisms, weed seeds, etc.
Likewise, organic amendments and fertilizers must have heavy metal contents below the maximum allowable levels established by current regulations.
