- Organic fertilisers do not contain synthetic chemicals, ensuring safety for soil organisms, plants, and the surrounding ecosystem.
- They promote sustainable agriculture by enhancing soil structure and reducing dependency on chemical inputs.
- Unlike herbicides, fungicides, and pesticides, organic fertilisers pose no toxicity risks to beneficial organisms in the soil, such as earthworms and microbes.
Additional Information

- Fungicides: Used to control fungal pathogens, these chemicals can harm beneficial fungi and microbes in the soil.
- Pesticides: These include a wide range of chemicals designed to kill pests but can also affect beneficial insects, soil organisms, and aquatic life through runoff.
