Algae fertilizer refers to the use of large algae growing in the ocean as raw materials, and the extraction of effective components from seaweed through chemical, physical, or biological methods, to make fertilizer and apply it to plants as nutrients. So, what are the characteristics of seaweed fertilizer compared to other fertilizers? What are the advantages? Let's take a look together next.
Characteristics and advantages of seaweed fertilizer
1. Rich in various natural growth substances.
For example, plant auxin, gibberellin, cell like division and polyphenol compounds have high biological activity, which can stimulate the production of non-specific active factors in plants and regulate the balance of endogenous hormones, promote photosynthesis of plants, make crops grow and develop coordinately, improve their vitality and resistance to diseases, insects, drought, waterlogging, low temperature and other stresses.
2. Compared with chemical fertilizers, it has incomparable advantages in terms of yield increase, stress resistance, naturalness, and no toxic side effects. Compared with conventional leaf fertilizers, in addition to significantly promoting crop growth, root development, improving photosynthesis, and strengthening plants, natural seaweed extracts are also rich in proteins, amino acids, carbohydrates, inorganic salts, vitamins, plant hormones, polyphenols, polysaccharides, and other bioactive substances, which can greatly improve crop quality, enhance disease resistance, cold resistance, drought resistance, promote early fruit ripening, and increase economic value.
3. Enhance the water absorption, water retention, drought resistance, and cold resistance of plants. It can be compounded with chemical fertilizer to form organic and inorganic compound fertilizer to enhance fertilizer efficiency, improve soil structure, increase soil air permeability and water retention capacity, and prevent soil deterioration. The mannitol contained can greatly increase the water absorption and retention capacity of crops, as well as the chlorophyll content, resulting in a leaf area increase of over 10%; Abscisic acid regulates leaf stomatal closure, reduces crop water loss, and can reduce fertilizer and water usage by about one-third.
4. It is a good pesticide dilution enhancer that forms a complex with pesticides through physical and chemical interactions. Due to the presence of polysaccharides in seaweed fertilizer, it has strong adhesion when mixed with most pesticides (excluding strong alkaline pesticides), which can significantly improve the efficacy and extend the efficacy period.
