Detailed nutrient profile of the organic fertilizer

Organic fertilizer contains a variety of nutrients essential for plant growth. The most important macronutrients and micronutrients in organic fertilizer are:

Macronutrients :

  • Nitrogen (N) – Promotes the growth of leaves and stems.
  • Phosphorus (P) – Supports root development and flower formation.
  • Potassium (K) – Strengthens cell structure and helps with plant disease resistance.
  • Calcium (Ca) – Strengthens cell walls and promotes the growth of roots and fruits.
  • Magnesium (Mg) – component of chlorophyll and important for photosynthesis.
  • Sulfur (S) – Participates in the formation of amino acids and proteins.

Micronutrients (trace elements) :

  • Iron (Fe) – Important for photosynthesis.
  • Manganese (Mn) – Supports enzyme activity and photosynthesis.
  • Copper (Cu) – Plays a role in the formation of enzymes.
  • Zinc (Zn) – Promotes plant growth and maturation.
  • Boron (B) – Supports cell division and the growth of roots and flowers.
  • Molybdenum (Mo) – Necessary for nitrogen fixation in plants.

Organic fertilizers provide these nutrients slowly but sustainably, as they decompose in the soil, providing plants with a consistent and long-term supply. Organic fertilizers also contain organic substances that improve soil structure and promote soil microbiology.
