Description

Device for producing liquid fertilizer using seaweed and liquid fertilizer produced thereby}

The present invention relates to a liquid fertilizer that simultaneously supplies inorganic matter and organic matter necessary for the growth of crops, and in particular, a liquid using seaweed that enables the recycling of pollutants by applying seaweeds such as green seaweed that are reflected on the shore as the main component of the liquid fertilizer. It relates to a fertilizer manufacturing apparatus and a liquid fertilizer manufactured thereby.

In general, fertilizer is one of the growth promoters that not only promotes growth during the cultivation process of crops, but also prevents various damages caused by diseases and pests. Such fertilizers are inorganic fertilizers obtained by chemical treatment or decomposition of animals or food. Organic fertilizers obtained in the process are widely known and used.

However, although the use of the inorganic fertilizer has the advantage of inducing rapid growth of the crop, various environmental damage including soil pollution due to the abuse of the inorganic fertilizer, as well as cancer due to the intake of harmful ingredients remaining in the crop The same secondary damage is caused, and its use is gradually restricted.

In addition, in the case of the organic fertilizer, a method of fermenting animals or plants is mainly used, but crops cannot be grown smoothly due to harmful gases such as ammonia generated during the fermentation and decomposition of the animals and plants. As reliability has declined, they are increasingly avoiding use.

On the other hand, instead of the inorganic fertilizer or the organic fertilizer, liquid fertilizer produced by fermenting microorganisms is on the rise, and the liquid fertilizer has a good effect on the growth of crops by secondary products generated in the process of decomposing organic matter by microorganisms. Of course, it is known to have high utility value due to low natural pollution.

However, since the liquid fertilizer is manufactured through a complicated manufacturing process, it is not only relatively expensive, and if the nutrients of the raw material added to the liquid fertilizer cannot be sufficiently extracted, it cannot contribute to the growth of the crop, and thus a large amount of the liquid fertilizer is used. Because it has no choice but to supply, the cost increases.

Therefore, in the process of growing the crop, not only nitrogen components or phosphoric acid components supplied through inorganic fertilizers or organic fertilizers are required, but mineral components such as magnesium and iron components are also required. There is an urgent need for research on liquid fertilizers.
