Fish protein liquid fertilizer has become a transformative force in sustainable agriculture. It provides a rich source of organic nutrients, promotes plant growth, improves soil health, and supports eco-friendly agriculture. This liquid fertilizer is extracted from whole fish or fish by-products and can directly deliver essential amino acids, peptides, and micronutrients to crops, enabling them to absorb and benefit from it quickly and with lasting effects.
LANE focuses on designing and supplying fish protein liquid fertilizer production lines, aiming to maximize nutrient retention, enhance production efficiency, and ensure consistent product quality for both small and large farms.
What is Fish Protein Liquid Fertilizer?
Fish protein liquid fertilizer is produced by enzymatically digesting fish material into a concentrated liquid form rich in nitrogen, phosphorus, potassium, and trace minerals. Unlike synthetic fertilizers, it offers a slow-release nutrient profile that supports plant health over a longer period, while also improving soil microbial activity.
This organic fertilizer is widely used in:
Vegetable farming (tomatoes, cucumbers, leafy greens)
Fruit orchards (grapes, apples, berries)
Greenhouse crops
Turf and ornamental plants
Regenerative agriculture projects
Not all fish fertilizers are equal. LANE’s enzymatic hydrolysis process preserves critical nutrients that cheap heat-processed products destroy:
Nutrient | Concentration | Plant Benefit |
Nitrogen (N) | 4-5% | Leaf growth |
Phosphorus (P) | 2-3% | Root development |
Potassium (K) | 1-2% | Fruit quality |
Amino Acids | 12-15% | Stress resistance |
Chitin | 0.5-1% | Pest resistance |
Pro Tip: Our 5-stage molecular filtration removes heavy metals while concentrating beneficial compounds—a process most competitors skip.
How Fish Protein Liquid Fertilizer is Made – Step by Step
Producing fish protein liquid fertilizer involves a carefully managed process to preserve amino acids, peptides, and micronutrients while ensuring a stable, easy-to-use product.
1. Raw Material Preparation: Fresh fish or by-products are cleaned in a stainless steel washing tank and fed into the system through a feed hopper.
2. Enzymatic Hydrolysis: The fish material is processed in an enzymatic hydrolysis tank with controlled temperature and pH to release nutrients.
3. Separation & Filtration: Using a centrifuge extractor and dual filter, solids are removed to produce a smooth, sediment-free liquid.
4. Blending & Nutrient Adjustment: In a stainless steel liquid mixer, micronutrients, stabilizers, or pH adjusters are added to meet specific crop needs.
5. Homogenization: A homogenizer ensures the fish protein liquid fertilizer is uniform and stable for storage.
6. Filling & Packaging: An automatic liquid filling machine bottles the product into retail or bulk containers, ready for market.
Step | Process | Key Equipment |
1 | Raw material cleaning & feeding | Stainless steel washing tank, feed hopper |
2 | Enzymatic hydrolysis | Hydrolysis reaction tank |
3 | Separation & filtration | Decanter centrifuge, dual-stage filter |
4 | Blending & adjustment | Horizontal liquid mixer |
5 | Homogenization | High-shear homogenizer |
6 | Filling & packaging | Automatic filling machine, capping & labeling unit |
