They are used in background fertilization and gradually release nutrients such as nitrogen, potassium or phosphorus but also trace elements essential for the good health of plants. assimilation is slower, there is no risk of leaching. As an example of organic fertilizer “compost and grass clippings do what fertilizers are supposed to do: they enrich the garden soil with nutrients that plants and microscopic forms of soil life they are eager to use”.
