 Five Characteristics Seaweed Fertilizer

Seaweed Fertilizer


Algae are grown in the ocean and low photosynthetic plant nutrition, it is the original producer of marine organisms. Since the algae is grown in seawater this particular environmental media, in addition to containing nutrients it possessed land plants, it also contains a number of terrestrial plants incomparable iodine, potassium, magnesium, manganese, titanium and other trace elements and seaweed polysaccharide , mannitol.

1. Seaweed Fertilizer Nutritious Than Conventional Fertilizers, Growth Equalized Applied To Crops Yield Significant Results, And Rarely Appeared Element Deficiencies.


Seaweed fertilizer with natural seaweed as the main raw material, extracted from seaweed contains a lot in favor of plant growth and development of natural bioactive substances and seaweed from the ocean to absorb and enriched mineral nutrients in the body, including seaweed polysaccharides, phenols more polyethylene compounds.


Mannitol, betaine, plant growth regulators (cytokinin, gibberellin, auxin and abscisic acid, etc.), and nitrogen, phosphorus, potassium and iron, boron, molybdenum, iodine and other trace elements.



2. Seaweed Contains A Lot Of Resistance Factors And Special Ingredients, Fertilizer Medicine Double Effect. After The Crop Resilience Administration Significantly Enhanced Disease Resistance, Spraying Pesticide Effect Can Be Improved.

Seaweed fertilizer seaweed polysaccharides and oligosaccharides contained, mannitol, poly-phenolic compounds, betaine, alginic acid and natural antibiotics and other substances, has significant antibacterial and antiviral, anthelmintic effect, really play a role in fat drug significantly enhance crop of cold, drought, disease resistance, lodging resistance, saline-alkali capacity, to disease, viral disease, anthrax, downy mildew, gray mold, powdery mildew, blight and other produce strong resistance. In addition, seaweed fertilizer alginic acid can reduce the surface tension of water, form a thin film on the surface of plants, increase the contact area, so that the water-soluble substance is relatively easy through the cell membrane into the plant leaf surface cells, the plants most effectively absorb seaweed extract nutrients. If the seaweed fertilizer and insecticides, fungicides mixed use, have a synergistic effect, can reduce spraying costs.


3. Seaweed Contains A Large Number Of Highly Active Ingredients, Easily Absorbed By Plants. After Crops Growing Strong, Can Significantly Improve The Yield And Quality Of Crops.


Seaweed unique seaweed polysaccharides, alginic acid, highly unsaturated fatty acids and other substances, has high biological activity, it can stimulate plants to produce non-specific active factors. Meanwhile, seaweed fertilizer also contains natural plant growth regulator, such as: auxin, cytokinin and gibberellins and other substances, the proportion of terrestrial plants, the proportion of each hormone is similar, with a good balance of endogenous hormones regulate effect. After administration crop yield and quality significantly improved, leafy yield more than 20%, to yield more than 15% of food crops, fruit trees and increase 10% to 30%, while the number of primary fruit of more than 80%, can significantly improve tobacco economic crop quality cotton, flowers, etc., especially for greenhouse vegetable crops, increase value-added effect is very significant.


4. Seaweed Fertilizer Rich In Organic Matter And Release Factor, Fertilizer Long, Can Improve Soil Microflora, Living Soil And Promote Root And Anti-Cropping.

Seaweed fertilizer can be used directly by plants or soil to increase soil organic matter, activated in a variety of beneficial microorganisms in soil. These microorganisms can act as a catalyst in a plant, microbial metabolism cycle, so that the biological effectiveness of the soil increases. Plants and soil microbial metabolites may provide more nutrients for the plants. Meanwhile, the formation of chelation system seaweed polysaccharides can make nutrition a slow release, extended fertility. In addition, it contains natural compounds such as sodium alginate is a natural soil conditioner, can promote the formation of soil aggregate structure, improve soil internal pore space, the solid coordination soil, liquid, gas three percentage recovery due to soil overburdened and chemical pollution and the loss of natural gums balance, increase soil biological activity, promoting the release of available nutrients, it is conducive to root growth, improve crop resistance and anti-cropping capacity.


5. Seaweed Fertilizer Pollution-Free Natural Security


Traditional chemical fertilizer fertilizer single, serious pollution, long-term use can cause soil structure is destroyed. Seaweed is a natural seaweed extract, and terrestrial plants have good affinity to human, animal non-toxic, environmental pollution, has the advantage of any other chemical fertilizers are unmatched in foreign countries were included in the organic food for fertilizer. Seaweed fertilizer polymerization variety of active substances in the ocean, offers many advantages nutritious, disease yield, live earth, pollution, is the real development of modern agriculture in line with good fertilizer direction.
