Organic Fertilizers Definition

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
