How to match Seaweed fertilizer with other fertilizer
Seaweed fertilizer is a new type of high-efficiency and environment-friendly fertilizer, which uses seaweed as raw material to break seaweed cells, release the contents, and then concentrate to form seaweed concentrate, which greatly retains the natural active components of seaweed.
Characteristics of seaweed fertilizer

1. Rich nutrition
Seaweed fertilizer is rich in more than 40 mineral elements such as potassium, calcium, magnesium, iron, zinc and iodine, which can comprehensively supplement the nutrition of crops and avoid the lack of certain trace elements and physiological diseases.
At the same time, it contains a large number of seaweed polysaccharides, phenolic polymers, mannitol, alginic acid, highly unsaturated fatty acids, amino acids, carbohydrates, inorganic salts, vitamins, polyphenols, polysaccharides, a variety of natural plant growth regulators and other natural bioactive substances, which can stimulate the production of non-specific active factors in plants and regulate the balance of endogenous elements, So as to improve yield and quality.

2. Easily absorbed by plants
After special treatment, the effective components of seaweed fertilizer are easily absorbed by plants, and the conduction speed in the body is very fast. They can enter the plants 2 ~ 3 hours after application. At the same time, alginic acid in seaweed fertilizer can reduce the surface tension of water. When water contacts the plant surface, it forms a film and increases the contact area. Water-soluble substances are easy to penetrate the stem and leaf surface cells, so that plants can effectively absorb the nutrients in seaweed fertilizer.

3. Improve soil and increase fertilizer efficiency
Seaweed fertilizer is a natural biological system, which can work harmoniously with plant soil ecosystem. It can increase organic matter in soil directly or through plants, and activate various microorganisms in soil. These microorganisms can act as catalysts in the plant microbial metabolite cycle, establish a complete ecosystem, increase soil biological efficiency, increase the metabolism of plants and soil microorganisms, and provide more nutrients for plants.

4. Enhance the disease, insect and stress resistance of plants
Phenolic polymers and betaine in seaweed fertilizer regulate the osmotic pressure of cell fluid and chloroplast, protect a series of enzymes from transforming into active resistant chemicals in the cells damaged by drought, cold and insect diseases, and have strong abilities of insect resistance, fungus resistance, nematode resistance, aphid resistance, cold and drought resistance. Iodide, copper and zinc in seaweed fertilizer are combined with humic salt to act on crops. It is a disease resistant bactericide with stable chemical properties.
It can improve the vitality and immunity of crops, inhibit plant diseases and insect pests, reduce the harm of drought, waterlogging, low temperature, salinity and other adversity to crops, and benefit the recovery of crops after disasters.

5. Improving quality, increasing production and environmental protection
Experiments and demonstrations on dozens of crops such as grain crops, cash crops, fruit trees and flowers in China, Thailand and Australia have proved that the yield increase of seaweed fertilizer is 8.6-36.5%, and the input-output ratio is 1:8.3-225.
At the same time, seaweed can significantly improve the quality of agricultural products and improve their commodity value. For example, it can improve the oil content of oil crops, improve the sugar content of sugar crops, improve the sweetness, flavor and color of fruits, improve the uniformity of products, promote the early maturity of crops, market in advance, prolong the storage period, etc.
Moreover, the raw material comes from natural seaweed, has good affinity with terrestrial plants, is non-toxic and harmless to human and livestock, and has no pollution to the environment. It is a high-quality fertilizer for the production of harmless vegetables.

Although seaweed is good, it also has defects
Seaweed fertilizer releases the cells, substances and contents contained in seaweed, and seaweed in the production area of seaweed raw materials generally absorb a large amount of inorganic salts. If a large amount of unreasonable use will lead to salt enrichment in the soil, which will seriously lead to soil salinization. Seaweed fertilizer with poor raw materials will be used to add some seaweed residue, When the addition amount of seaweed residue exceeds 30%, the heavy metals must exceed the standard, so the more seaweed fertilizer is used, the better. It will also have defects!
Therefore, seaweed fertilizer is good, but it is better to match with the following types!
It's better to match these two
1. Compound microorganism
The role of microbial bacteria is very strong. It is well known to the public. It can promote the repair of roots, take root, nourish roots and protect roots, inhibit harmful bacteria, improve and activate soil, improve soil salinization, fix nitrogen, hydrolyze phosphorus and potassium, improve fertilizer utilization, and so on.
For example, the combination of Bacillus subtilis and Trichoderma harzianum combined with seaweed fertilizer will greatly improve the efficiency of soil improvement, repair damaged roots, inhibit the infection of harmful bacteria, protect and promote the growth of crop roots, and avoid the phenomenon of soil salt enrichment.
2. Mineral humic acid
Mineral derived humic acid also has a strong effect on soil, crop roots, microbial flora in soil and soil aggregate structure. It not only promotes crop rooting and root growth, but also directly acts on soil, improves soil aggregate structure, improves activated soil, alleviates continuous cropping, reduces heavy metal pollution, and improves fertilizer utilization rate.
Combined with seaweed fertilizer, it can promote each other and make up for some deficiencies of seaweed fertilizer.
