Liquid Biofertilizers from Seaweeds: A Critical Review

Application of various seaweed products such as seaweed liquid fertilizer and seaweed manure improve soil texture and structure, which facilitates better aeration of the soil, enhanced nitrogen fixation, and improved proliferation of beneficial soil microorganisms.

What are the characteristics and advantages of seaweed fertilizer

Compared with chemical fertilizers, it has incomparable advantages in terms of yield increase, stress resistance, naturalness, and no toxic side effects.

Seaweed

One of the most frequently used seaweed-based fertilizing products (SFPs) is plant growth biostimulants applied in the form of extracts. This chapter presents examples of seaweed-based fertilizing products, methods of their production, as well as their effect on plant growth.

Seaweed fertilizers, as a新兴 agricultural resource, are gaining global attention due to their unique bioactivity and eco-friendly properties. Below is a detailed introduction to their efficacy and characteristics:

I. Basic Concept of Seaweed Fertilizers

1. Definition and Composition: Seaweed fertilizers are primarily made from marine microalgae through extraction and fermentation processes. They contain abundant nutrients and bioactive substances, which provide essential nourishment for plants and promote their growth.

2. Classification and Applications: Based on sources and processing methods, seaweed fertilizers can be divided into:

   • Natural seaweed fertilizers: Derived directly from ocean resources, known for their environmental friendliness.
   • Synthetic seaweed fertilizers: Produced artificially. Both types meet plant nutritional needs but differ in specific functions.

II. Nutrient Content of Seaweed Fertilizers

1. Nitrogen Content: Rich in proteins, amino acids, vitamins, and minerals, seaweed fertilizers contain nitrogen in an organic form that is easily absorbable by plants.

2. Phosphorus, Potassium, and Other Elements: Besides nitrogen, they provide essential elements like phosphorus and potassium, which are critical for photosynthesis, growth, and stress resistance in plants.

3. Trace Elements: Seaweed fertilizers also include beneficial trace elements (e.g., iron, zinc, manganese) that enhance plant development and improve crop quality.

III. Bioactivity of Seaweed Fertilizers

1. Growth Promotion: Bioactive compounds such as polysaccharides, peptides, and flavonoids boost plant immunity, stress resilience, and overall growth.

2. Yield Increase: Studies show that seaweed fertilizers significantly improve crop yields by enhancing photosynthesis and nutrient utilization efficiency.

3. Quality Improvement: Crops treated with seaweed fertilizers often exhibit better taste, color, and nutritional value, enhancing market competitiveness.

IV. Environmental Benefits of Seaweed Fertilizers

1. Reduced Chemical Fertilizer Use: As organic alternatives, seaweed fertilizers reduce reliance on synthetic chemicals, minimizing soil and environmental pollution.

2. Ecosystem Protection: Their marine origin and eco-friendly production processes make them sustainable choices. Crops grown with seaweed fertilizers also pose fewer environmental risks.

3. Ecological Balance: By providing diverse nutrients, seaweed fertilizers support marine microbial ecosystems, fostering biodiversity and ecological balance.

V. Future Prospects of Seaweed Fertilizers

1. Agricultural Applications: With growing emphasis on food safety and sustainability, seaweed fertilizers are poised to become indispensable green fertilizers in agriculture.

2. Industrial Uses: Beyond agriculture, they hold potential in industries like food additives and cosmetics as natural ingredients.

3. Research and Development: Ongoing scientific studies focus on optimizing formulations, production techniques, and applications, driving innovation in this field.

seaweed fertilizers stand out for their unique nutrient profiles, bioactivity, and environmental benefits, emerging as a vital resource in modern agriculture. With advancing technology and market demand, their applications are set to expand significantly.
