Why seaweed fertilizer in market is so different

Why seaweed fertilizer in market is so different 

The prices of seaweed Extract products sold by different brands and manufacturers vary greatly. What is the reason for this? First of all, the active ingredients contained in different seaweeds must be different. The best seaweed fertilizer extraction raw materials must be extracted from giant spirulina, Ascophyllum nodosum and other seaweeds in the deep sea. If you use fertilizers extracted from shallow seas, such as kelp and seaweed, the effect will definitely be less effective and the cost will be lower. Secondly, seaweed produced at different latitudes has different contents of active substances. Because high-latitude seaweed has lived in deep seas and low-temperature areas for a long time, the seaweed contains more cold-resistant and active substances. In addition, high-latitude seaweed grows slower, and the active ingredients contained in it will be higher. In addition, the extraction process of seaweed Extract is different. A good extraction process requires good equipment and higher conditions, so the cost will naturally be high. Furthermore, seaweed Extracthas purity. The higher the purity, the higher the content of nutrients, and the higher the cost. Many manufacturers only say that they are seaweed Extract, but do not label the specific content. You can imagine the reason why the price is so low. There are even some unscrupulous merchants who directly pass off humic acid as seaweed Extract. Therefore, when purchasing seaweed Extract, you should not just look at the price. You must also look for the qualifications of the company and the qualifications of the product.
