A natural fertilizer is a substance of plant or animal origin, used to nourish plants and improve soil quality. Unlike chemical fertilizers, which act quickly but can disrupt the soil's balance, natural fertilizers offer a gradual, environmentally friendly action.
đ The main functions of a natural fertilizer
- Nourish plants: Provide essential nutrients such as nitrogen, phosphorus, and potassium.
- Strengthen the immune system: Help plants better resist diseases and environmental stress.
- Preserve soil balance: Improve soil structure, fertility, and water retention capacity.
A natural fertilizer can also be used occasionally to:
- Correct a nitrogen, phosphorus, or potassium deficiency.
- Improve soil quality during planting.
- Acidify or alkalinize the soil according to plant needs.
