The essence of agriculture lies in building a bridge of nutrients and vitality between soil and crops. With the rise of green agriculture, biostimulants—derived from natural sources like seaweed, animal and plant residues—are emerging as a new engine for modern farming.
Unlike traditional fertilizers or pesticides, they are made by extracting active ingredients from natural raw materials through scientific processes. They not only supplement nutrients for crops but also activate their inherent potential while improving soil ecology. From the deep-sea energy of seaweed to the natural protection of crustacean shells, these nature-sourced substances are making cultivation more efficient and eco-friendly.
I. Core Biostimulant Products: Full Breakdown of Nutrients and Efficacy

II. Raw Material and Process Characteristics of Core Products
1. Seaweed Acid: A “Crop Vitality Source” from the Deep Sea
Seaweed acid is a natural active polysaccharide in seaweed cells. Seaweed fertilizer, centered on seaweed acid, is a green fertilizer made by extracting marine algae. Different extraction processes directly determine its effectiveness:
- Chemical hydrolysis (common but flawed): Strong alkali and high temperature destroy endogenous active substances in seaweed;
- Enzymatic wall-breaking: Single product, large molecular weight, and low crop absorption efficiency;
- Biological fermentation (patented technology of Enbao Biotechnology): Uses solid-state fermentation with cell wall autolysis to maximize the retention of natural active ingredients in seaweed.
2. Chitin: A “Soil and Crop Protection Shield” of Natural Biopolymer
Chitin (also called chitin) widely exists in the exoskeletons of arthropods and cell walls of fungi. It is a natural linear polysaccharide, with extraction technologies including chemical methods, biological enzymatic methods, and physical crushing.
3. Humic Acid: A “Soil Improver” from Animal and Plant Remains
Humic acid is organic matter formed by microbial decomposition of animal and plant remains and a series of complex geochemical reactions. It is divided into coal-based humic acid (extracted from coal, requires chemical treatment, low cost) and biochemical humic acid (fermented from straw and bagasse, containing active substances like amino acids and enzymes).
4. Amino Acids: The “Essential Nutrient Unit” for Crops
Amino acids come from plant sources (soybeans, cake meal, etc.) and animal sources (leather, fish meal, etc.). Production methods include acid hydrolysis (low cost, simple process), fermentation (long production cycle), and enzymatic hydrolysis (high cost, but retains comprehensive amino acid types and high activity).
5. Fish Protein: A “Compound Active Fertilizer” from Low-Value Fish and Shrimp
Fish protein is made by enzymatic/microbial degradation of low-value fish and shrimp. It contains not only amino acids but also active substances like polypeptides and biological polysaccharides (fish protein produced by biological fermentation has richer activity).
Conclusion
From deep-sea seaweed to terrestrial straw, from crustacean shells to fish and shrimp protein, biostimulants are reshaping the nutrient logic of modern agriculture with their “nature-sourced, agriculture-empowering” characteristics.
