What is a natural fertilizer?

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.

🔍 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.
