The seaweed extract consists of nitrogen, phosphorus and potassium, organic matter, seaweed extracts, refined humic acid, amino acids, proteins,beneficial active bacteria and other raw materials. It is especially added with rooting agents, trace elements, etc., and refined by scientific formula. The development of seaweed has gone through three stages: decaying seaweeds → seaweed ash (powder) → seaweed extracts. Therefore, natural seaweed fertilizers are the most needed fertilizer for the development of organic agriculture.
The seaweed extract can work in harmony with the plant-soil ecosystem. It contains natural compounds. For example, sodium alginate is a natural soil conditioner that promotes the formation of soil aggregates, improves the pore space within the soil, and coordinates the solids in the soil.
The proportions of liquid and gas will restore the natural gum balance lost due to overburdened soil and chemical pollution, increase soil biological activity, increase the release of available nutrients, and facilitate the growth of roots and improve the resistance of crops.
Continuous use of seaweed extract can improve the soil, promote deep rooting of crops, enhance immunity, destroy harmful bacteria, eggs, reduce the amount of pesticides, and reduce the harm of phytotoxicity and fertilizer. Long-term use can loosen the soil, make the crops resistant to high temperature, drought, increase the temperature, prevent freezing, and resist heavy weight, so that the crops can fully absorb the nutrient of nitrogen, phosphorus and potassium in the soil, improve the photosynthesis of crops, improve the metabolism, and make nutrients. The utilization rate reaches the highest value, and the effect of increasing production is very significant.
The Traditional chemical fertilizers have a single fertilizer effect and serious pollution, and long-term use will result in the destruction of the soil. Seaweed fertilizer is a natural seaweed extract that is harmless to humans and livestock and has no pollution to the environment. It is listed as a special fertilizer for organic foods in foreign countries. Seaweed extracts and series products are very suitable for the production of green foods and organic foods in China. The functions of the seaweed extracts and series products make up for the shortage of traditional organic fertilizers in China and slower fertilizer efficiency. Its application will help China's agricultural products enter the international market. According to statistics, there are more than 100 kinds of large-scale economical seaweeds in China, among which there are no shortages of high-efficiency species and abundant resources. The prospects for the development and application of seaweed fertilizers are broad.
