Organic Fertilizer Definition

  • Organic fertilizers are derived from plants or animals, excluding petroleum industry by-products.
  • These fertilizers undergo substantial decomposition, making nutrients available to plants.
  • The total nutrient content of organic fertilizers must fall within the range of 5-10% for:
    • Nitrogen (N)
    • Phosphorus (P2O5)
    • Potassium (K2O)
  • Organic fertilizers may be enriched with microbial inoculants and naturally occurring minerals.
  • No chemical or inorganic fertilizer materials are used in the production or added to the finished product to alter nutrient content, adhering to PNS/BAFS 183:2016 standards.

Composting Process

  • Composting is a managed process that utilizes microorganisms naturally present in organic matter and soil to decompose organic materials.

Microorganism's Role

  • Microorganisms play a crucial role in breaking down organic matter into nutrient-rich compost.

Microorganism's Requirements

  • Microorganisms require Carbon for energy and Nitrogen for Protein Synthesis to grow and multiply.

Carbon Source

  • Carbon is obtained from “brown” materials in the compost pile, such as: • Dried leaves • Straw • Paper

Nitrogen Source

  • Nitrogen comes from “green” materials, such as: • Grass clippings • Kitchen scraps
