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
