Seaweed Extract “Power” is an advanced biological fertilizer invented by Dongyang Lianfeng Biological Technology Co.，Ltd. by merging multi-principle technologies of plant nutrition and immunology.
　　Seaweed Extract “Power” is a 100% natural seaweed extracts produced by two-phases fermentation using sea plants, lichen, and plant pollen etc as raw materials in the presence of specific fermentative bacteria. The natural bioactive materials in seaweed are furthest maintained in “Power” by using unique biological techniques instead of high pressure, high temperature and chemical processing.
　　The principium of microbe zymotechnics in producing Seaweed fertilizer is: by using multifold enzyme which is obtained during the process of microbial metabolizing, to decompose larger molecule substances of seaweed into smaller and water-soluble ones, so that they can both be absorbed by microbes itself for growth and reproduction, and be absorbed easily by the roots and leaves of plants as nutrients and bioactive substances.
　　The leading advantage of zymotechnics is the multiformity of the effective ingredients of the end product, which can be absorbed completely easily by plants. Therefore "Power" is a highly effective and high-activity bioactive seaweed fertilizer.
　　Fermented seaweed extracts "Power" is a perfect multifunctional fertilizer converging nutirents, bioactive substances and counter-stresses genes. All of substances contained in "Power" is from completely nature, so “Power” is safe to humans being, animals and the environment.
　　“Power” has its advantages in product composition and concentration of nutrients and processing techniques over other fertilizers:

　　1) Benefit to the environmental protection
　　Long term use of traditional chemical fertilizers will damage the physical and chemical properties, the biological characteristics, and the micro-ecology of soil, leading to deterioration of quality of plant products. However, Seaweed Extract “Power” is quite different from the traditional chemical fertilizers because it is a natural product derived from algal materials and it can complex with heavy metal ions in soil and enhance the permeability of soil. Therefore, “Power” can help soil to avoid erosion by wind or water and it can enhance the resistance of crop plants to adverse factors. Also Seaweed Extract is safe to humans and animals, and the environment.

　　2) Low application rate, Highly effective
　　It is a highly effective fertilizer because it contains both nutritious materials and regulatory matters. Extremely low dose of “Power” could reach much higher effects than traditional fertilizers.

　　3) Easily to be utilized by crops
　　Seaweed Extract “Power” could be quite absorptive and highly efficient to crop plants because it is manufactured by unique processing techniques to obtain extremely fine particles. Seaweed Extract could be absorbed by plant within several hours after application.

　　4) Wide application scopes
　　Many experiments have been conducted and the results indicated that Seaweed Extract “Power” is highly effective on grain crops such as corn, rice, barley, and wheat, on vegetables such as sweet potato, potato, peanut, pea, cucumber, tomato, eggplant, Chinese cabbage, water melon, celery, garlic, green Chinese onion, and ginger, on fruit trees such as apple, pear, peach, persimmon, orange, banana, mango, grape, and jujube tree, particularly on cotton, tobacco, mulberry, and tea.

　　5) Rich in variety of nutrients
　　Seaweed Extract “Power” contains various nutrients of macroelements and microelements ( N, P, K, Ca, Mg, S, Fe, Mn, Cu, Zn, Mo, B etc.) as well as 18 kinds of protein amino acids, plant growth regulators (auxins, cytokinin and gibberellins etc.), arachidonic acid，vitamines, nucleotides, alginic acids, humic acids and counter-stresses genes, which can be easily absorbed by plants, and stimulate plants to generate specific biological factors, which may promote plant growth.

　　In conclusion, “Power” is a new generation of natural fertilizer containing highly effective nutritious, which can significantly increase yields of many crops and enhance the resistant ability of plants to adverse factors. This product will greatly contribute to the agriculture because it is safe to the environment and highly economical.

2 Processing techniques
2.1 The processing system

2.2 Product processing
Select raw materials and dry under 60℃. Grind the material to 0.1 mm particles. Mix the ground raw materials together proportionally. Then put the mixture into fermentation tank and add fermenting microorganisms. The materials in the fermentation tank undergo two phases fermentation and the seaweed extract is obtained after fermentation.

3 Product Toxicology
3.1 Acute toxicity
3.1.1 Acute oral and inhalation toxicity

3.1.2 Acute skin and mucous membrane irritation tests
　　1) Tails of rats are dipped in the solution of the fertilizer for 4 hours.
　　● No change on skin observed.
　　● No changed observed on main functions.
　　● No mortality observed.
　　2) The lowest limit of rabbit mucous membrane irritation：11.7g/L

3.2 Accumulative toxicity and effects on the environment
3.2.1 Accumulative toxicity
　　① Inject “Power” fertilizer at dose of 525mg/kg into stomach of laboratory animals, very less 　　accumulation is observed but no effects on the function of internal organs of the body.
　　Following administration of the fertilizer, approximately 74.2% of the administered dose was recovered within 12~13hours in urine (17.3%) and faeces, 91~92% was recovered within 18 hours, nothing was recovered 24 hours after administration.
　　② No accumulative toxicity in plants、soil and water
　　● In plants the fertilizer was metabolized within 2~3days, and the metabolites were incorporated in the plant metabolism.
　　● In soil the fertilizer was oxidized and was transformed into humic acids.
　　● In water microorganisms degraded it within 13 days and CO2 and H2O were formed.
3.2.2 Acceptable Daily Intake, ADI = 0.2g/kg/day
3.2.3 Toxicity to fish : To Cebreteg reticulates acute LC50(48hr) = 27g/L
3.2.4 Toxicity to aquatic organisms: To Daphnia pulex LC50(48hr)=17.4g/ L

4 Functions and characteristics
1) Enhance plant vigor, improve quality of crop products, and increase yield
　　The Fermentd Seaweed Extract contains a lot of nutrients which are easily to be absorbed and transformed by plants, and it promote growth of plants.
　　Gibberellin contained in the product could induce the re-formation of α-amylase，promote cell dissociation and elongation. It could also break the dormancy of seeds, tuber, and bulb，promote germination，adjust the shape of flower plant, promote elongation of flower stem, protect the flowering and fruiting of vegetables and fruits, and increase their yield.
　　The Seaweed Extract contains quinonyl and polyphenol-combined humic acid which take part in redox reaction and increase the activity of α-amylase and the synthesis of phosphorus compounds---leading to increase of sugar content in fruits and melons. In addition，this product could also extend the flowering period for about 40 days and the storage durability for 10 to 30 days.

2) Enhancing the ability of water absorption and maintenance and resistance to drought and cold
　　The product contains mannitol which can enhance water absorption ability and increase the content of chlorophyll in plant leaves and the leaf area by 10%. The Seaweed Extract contains abscisic acid which can adjust the open and close of air hole in plant leaves, reducing loss of water and saving one third of water and fertilizer.

3) Enhancing the resistance to pests and diseases and stresses
　　Phenol polymers and betaine contained in “Power” can adjust the osmotic pressure of cell fluids and chloroplast to protect the activities of enzymes in plant cells, and marktedly enhance the resistance of plant to pests, fungus, diseases and adverse factors.
　　The product contains iodide, copper, and zinc which could combine with humic acids to form a stable complex resistant to plant diseases.

4) Effective soil amendment
　　Extract of algae can combine with humic acids in soil，enhancing aggregate structure and its water maintenance ability by 10 times and aggregation force by 7 times, activating microelements in soil, improving the development of roots, enhancing the ability of roots to absorb nutrients in soil, and modifying soil fertility.
