The present invention relates to a liquid fertilizer prepared by using sericite (sericite, mica) and a method for preparing the same. More specifically, the present invention relates to an alkaline solution containing a large amount of potassium, calcium, and sodium as well as a pH of 12.5. The present invention relates to a liquid fertilizer rich in alkaline ingredients that can promote plant growth as well as neutralize acidic soils to alkaline soils by producing liquid fertilizers and a method for producing the same.

In order to meet the demand for food due to the rapid development of the industry and the explosive growth of the population, the output per unit area must be increased, and the use of pesticides and chemical fertilizers has been rapidly expanded. Conventional farming concentrated on chemical fertilizers and pesticides has resulted in a decrease in intellect and acidification of the soil.

As the above problems emerge, organic fertilizers or composts are used in place of chemical fertilizers or pesticides, and further efforts have been made to improve fermentation production methods using microorganisms.

However, in order to manufacture organic fertilizers, it takes a long time and excessive devices by fermentation of microorganisms, which makes it difficult to use them in actual production, and causes water pollution by waste water due to the production of such fertilizers.

In addition, organic fertilizers lack the trace elements essential for the growth of plants have the disadvantage of being pest.

Accordingly, the present invention solved the above problems by producing a liquid fertilizer using the sericite as a main raw material invented to solve the above problems.

Sericite, also known as chorus, originally referred to as the main component mineral of crystalline schist, especially chorus schist, today refers to clay-like fine muscovite produced by hydrothermal action. The chemical composition is almost the same as that of the mica, but generally potassium (K) is less than that of the mica and somewhat more water (H₂O).

Sericite is used as a mixing material for ceramics and refractory bricks. In addition, sericite has been used in various applications such as paints, electrical insulators, active materials, and cosmetics, but is rarely used as a raw material for fertilizers.

However, when sericite is mixed with water, heat treated with good stirring, and then precipitated, a liquid containing large amounts of elements such as potassium and calcium and small amounts of sodium, which are essential for plant growth, is required. Can produce fertilizer.

Potassium among these components, together with nitrogen fertilizer and phosphate fertilizer, influences the growth of plants. Potassium is necessary for photosynthesis and the synthesis of proteins from amino acids, and is a necessary ingredient to help the physiology of plants and to strengthen plants.

Lack of potassium leads to poor growth and darker leaves. When it gets worse, the leaves have brown spots and the tip of the leaves become red. It also weakens droughts and pests.

Calcium is the fourth most common nutrient that must be absorbed after nitrogen, phosphoric acid and potassium. Enough calcium is enough to make the plant's cell membranes strong enough to produce solid crops of good color. In other words, if calcium is insufficient, growth is inhibited and leaf size becomes smaller, and the stem becomes thinner.

When calcium is insufficient, crops have umbilical rot (watermelon, tomatoes, peppers), tip burn phenomenon (lettuce, lily, leek, onion, leek, garlic), parachute leaves (cucumber), water melon (melon, melon), dobok phenomenon (green onion) , Onions, rice, etc. happen well. If salt concentration is high in soil and fertilizer level is high, calcium absorption is not good, and dry and strong sunlight tends to cause calcium deficiency in crops. In this case, it is very important to spray calcium fertilizer that is absorbed well.

Sodium has nine major elements such as nitrogen (N), phosphorus (P) and potassium (K), and seven major elements such as iron (Fe), manganese (Mn) and boron (B), as well as silicon, aluminum, nickel and cobalt. It is classified as an essential element necessary for crop growth along with six elements such as vanadium and vanadium, and is contained in natural salt. However, as with trace elements such as iron, it is not necessary. Therefore, the liquid fertilizer contains only a small amount necessary.

This liquid fertilizer was mixed with 25 to 35% by weight of sericite and 65 to 75% by weight of water crushed with 300 mesh, then transferred to a stirrer and stirred at 1.5 to 2,5 hours while heating to 70 to 90 ° C. After discharging with a pump and transporting to a tank, the precipitate is precipitated for 3 to 4 hours, and then the sericite powder is settled down, and the above components are concentrated thereon to collect the liquid.

In this way, the liquid collected on the sericite powder becomes liquid fertilizer.

Hereinafter, the present invention will be described with reference to the drawings.

1 is a process chart showing a process for producing a liquid fertilizer according to the present invention.

First, 25 to 35% by weight of sericite ground to about 300 mesh and 65 to 75% by weight of water are mixed.

Sericite must be crushed to 300 mesh to mix well with water.

General water may be used, but since such water contains impurities, it is preferable to use distilled water.

Also. Water can be mixed well with sericite by using water heated to 60 ~ 70 ℃ in the water heater in advance, and it can save fuel.

The mixture thus mixed is put into a stirrer and stirred for 1.5 to 2.5 hours. The stirrer has a double structure, a heating means is built in the double structure, and a stirring blade is provided inside the stirrer. Therefore, while the mixture is heated to 70 to 90 ° C. on the one hand and stirred for 1.5 to 2,5 hours by the stirring blade on the one hand, chemical change gradually occurs in the mixture. The agitated mixture is transferred to a tank and allowed to settle for 3 to 4 hours so that the sericite powder sinks to the bottom and liquid is accumulated thereon. As a result of collecting the liquid collected on the sericite powder as described above, the results are shown in the table below (Analytic Institution: Korea Mining Promotion Agency).
