1、含氨基酸水溶肥料研究现状及其在农业生产中的应用

本文综述了氨基酸原料的来源和生产工艺，含氨基酸水溶肥料的功能特点、发展现状、在农业生产中的应用和未来发展趋势。 结果表明：含氨基酸水溶肥料在粮食作物、蔬菜作物、水果作物、经济作物中均有广泛应用，对作物生长、果实品质提升和土壤改良等有积极作用，然而在不同作物上的应用需根据其生长发育规律和营养需求进行进一步探索。 单一营养型的含氨基酸水溶肥料已不能满足市场需求，需开发功能与营养相结合的新型含氨基酸水溶肥料。

2、Current Trends on Seaweeds: Looking at Chemical Composition

These are polymers resulting from the combination of different amino acids linked by an amide bond, where there are different ratios of each amino acid and 20 different amino acids (Figure 1), nine of which are essential amino acids (i.e., that must come from food).

3、Types and Functions of Amino Acid Water

Amino acid water-soluble fertilizer is a new type of fertilizer that combines the advantages of amino acids and water-soluble fertilizers, providing comprehensive and efficient nutritional support for plants.

4、Seaweed

Mycosporine-like amino acids (MAAs) are water-soluble secondary metabolites characterized by low molecular weight. They are commonly found in various marine algae, specifically in the intracellular space and surrounding cell organelles, where they protect against UV rays [1].

Seaweed fertilizer vs amino acid vs humic acid vs fish protein vs

At present, there are many kinds of new water-soluble fertilizers on the market, such as humic acid, amino acid, fish protein and seaweed element. Not only farmers but also many dealers and manufacturers are confused.

Research Status of Water

The study reviewed the source and production technology of amino-acids raw material, the functional characteristics, the development status, the application in agricultural production and the future development trend of water-soluble fertilizers containing amino-acids.

Seaweed Proteins: A Step towards Sustainability?

Exploring the nutritional composition, extraction methods, functional properties, and potential health benefits of seaweed proteins, this review provides a comprehensive understanding. Seaweed contains essential amino acids, vitamins, minerals, and antioxidants.

Seaweed Proteins and Amino Acids as Nutraceuticals

Seaweed protein is a source of all amino acids, especially glycine, alanine, arginine, proline, glutamic, and aspartic acids. In algae, essential amino acids (EAAs) represent almost a half of total amino acids and their protein profile is close to the profile of egg protein.

Phytochemical and Potential Properties of Seaweeds and Their Recent

Marine macroalgae, sometimes known as seaweeds, are microscopic, multicellular, photosynthetic eukaryotic creatures. Based on their coloration and depending on their taxonomic classification, they can be classified into three groups: Rhodophyta (red), Phaeophyceae (brown), and Chlorophyta (green).

Seaweed bioactives potential as nutraceuticals and functional

The dietary fibre present in marine algae is divided into two types: insoluble (such as cellulose, mannans, and xylan), and water-soluble dietary fibre (such as agars, alginic acid, carrageenan, furonan, laminaran, and porphyran) (Holdt and Kraan, 2011).

Seaweed water-soluble fertilizer is a nutrient product made from marine plants (seaweed) through processes such as extraction and fermentation. Rich in amino acids, minerals, vitamins, and other active ingredients, it significantly promotes plant growth. Below are common types of amino acid-containing seaweed water-soluble fertilizers:

1. Seaweed Polysaccharide Water-Soluble Fertilizer Seaweed polysaccharides, natural high-molecular-weight carbohydrates with high bioactivity, are combined with amino acids and minerals. This fertilizer enhances photosynthetic efficiency, strengthens disease resistance, and accelerates plant growth.

2. Calcium Alginate Water-Soluble Fertilizer Calcium alginate, a natural calcium source, replenishes essential calcium for plants. It contains amino acids and minerals that improve stress tolerance and growth vigor.

3. Seaweed Polyphenol Water-Soluble Fertilizer Seaweed polyphenols, natural antioxidants, scavenge free radicals to protect plant cells. This formula boosts photosynthesis and supports healthy growth.

4. Seaweed Protein Water-Soluble Fertilizer Derived from seaweed proteins, this fertilizer provides a rich source of amino acids and minerals, enhancing photosynthetic performance and growth rates.

5. Compound Seaweed Polysaccharide Water-Soluble Fertilizer A blend of multiple seaweed polysaccharides, this product delivers balanced nutrients (amino acids, minerals, vitamins) suitable for diverse plants. It improves photosynthesis, disease resistance, and growth.

6. Magnesium Alginate Water-Soluble Fertilizer Magnesium alginate supplies essential magnesium, while amino acids and minerals in the formula enhance plant resilience and development.

7. Compound Seaweed Polyphenol Water-Soluble Fertilizer A mix of seaweed polyphenols and minerals, this fertilizer acts as a potent antioxidant and growth promoter for various crops.

8. Compound Seaweed Protein Water-Soluble Fertilizer Combines multiple seaweed proteins to provide a concentrated source of amino acids and minerals, optimizing photosynthesis and growth.

9. Seaweed Polysaccharide Enzyme-Compound Water-Soluble Fertilizer Formulated with seaweed polysaccharides and enzymes, this product supplies amino acids, minerals, and enzymatic agents to boost photosynthetic efficiency and overall plant health.

10. Magnesium Alginate Enzyme-Compound Water-Soluble Fertilizer A blend of magnesium alginate and enzymes, this fertilizer offers amino acids, minerals, and enzymes to support robust growth and stress resistance.

Amino acid-containing seaweed fertilizers vary in composition and benefits. When selecting a product, consider the specific needs of plants at different growth stages. Proper application is critical; excessive use may lead to nutrient imbalances or deficiencies, harming plant health. Prioritize tailored formulations and moderation for optimal results.
