1. Natural Nitrogen Source (Organic Sources)
These are plant-based, animal-based, or microbial sources of nitrogen.
✔ Green Manure – Fresh plant materials (e.g., Ipil-Ipil, Madre de Agua) incorporated into the soil.
✔ Compost – Decomposed organic matter rich in nitrogen.
✔ Animal Manure – Chicken, cow, goat, or rabbit manure.
✔ Fish Amino Acid (FAA) – Fermented fish waste as a nitrogen-rich liquid fertilizer.
✔ Fermented Plant Juice (FPJ) – Extract from nitrogen-rich plants (banana trunk, kangkong, kamote tops).
✔ Vermicast (Worm Castings) – Organic waste processed by earthworms.
2. Synthetic or Commercial Nitrogen Fertilizers
These are manufactured fertilizers that provide nitrogen in different forms.
✔ Urea (46-0-0) – High-concentration nitrogen fertilizer.
✔ Ammonium Sulfate (21-0-0) – Provides nitrogen and sulfur.
✔ Calcium Nitrate (15.5-0-0) – Quick-release nitrogen source.
✔ Complete Fertilizer (14-14-14, 16-16-16) – Contains nitrogen, phosphorus, and potassium.
3. Microbial & Atmospheric Nitrogen Sources
These use natural processes to enhance nitrogen availability.
✔ Nitrogen-Fixing Plants (Legumes) – Plants that convert atmospheric nitrogen into a usable form.
✔ Nitrogen-Fixing Bacteria (Rhizobia, Azospirillum, Azotobacter) – Found in healthy soils and legume roots.
✔ Rainwater & Lightning – Natural nitrogen deposition from the atmosphere.
Final Recommendation
For organic methods → Use Organic Nitrogen Fertilizer
For synthetic fertilizers → Use Inorganic Nitrogen Fertilizer
For microbes & legumes → Use Biological Nitrogen Fixation
