Phosphoric acid fertilizer for supplementing phosphoric acid and manufacturing method

The present invention relates to an additional cost phosphate fertilizer composition and a method for producing the same. More specifically, the present invention relates to an additional cost phosphate fertilizer composition and a method for preparing the same, which are easily insolubilized in the aerobic composition so that the fertilization effect can be drastically reduced, and the fertilization of phosphoric acid known to be impossible to add is possible. will be.

In order for crops to grow normally, carbon (C), hydrogen (H), oxygen (N), nitrogen (N), phosphoric acid (P), kali (K), calcium (Ca), magnesium (Mg) and sulfur (S) ), Iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), boron (B), molybdenum (Mo), chlorine (Cl) is known to require 16 nutrients. Of these 16 nutrients, carbon, hydrogen, and oxygen are naturally supplied from air or water, and the rest of these elements can be obtained directly or indirectly from soil rock, which is also called an essential mineral element. Among these, six elements such as nitrogen, phosphoric acid, kali, lime, magnesium, and sulfur are called large or bulk elements because they require large amounts of plants. Iron, manganese, boron, zinc, molybdenum, and copper are plant nutrients. These are called trace elements because they are required in very small amounts. Although these trace elements and large elements differ in quantity, there is no difference in quality and they are equally important for plant growth. This is already known by the laws of plant production known by German scientists Liebig and Wolf. "The production of plants is governed by the least amount of inorganic components," says Wolfe. "In order to achieve the expected output by using a minimum of one component, you must give enough of the other components." This is called the minimum nutrient percentage, and the latter is called Wolf's law.

What we can see here is that no matter how many specific ingredients we use in growing our crops, if the nutrients are not balanced our desired output will never be harvested. Therefore, fertilization management should always be carried out with balance fertilization in mind so as not to overload the essential nutrients necessary for the crop.

However, till now farming methods are indispensable for the growth of crops such as nitrogen, phosphoric acid and kali by the period of crop growth by the initial period of fertilization (method of fertilizing the soil directly before sowing). The main ingredients are to supply. However, unlike nitrogen and kali, phosphoric acid may vary depending on soil, temperature, humidity, etc., but the residual effect is only about 15 to 30 days, and since it is insoluble, it does not help to grow the actual crop. . This is due to the nature of phosphoric acid and the relationship between the soil and the plant's absorption capacity is different from that of nitrogen and kali, and even if it is added to the soil, it is fixed to the soil and changes to insoluble before reaching the root. Not enough to help the plant grow, so after feeding at the time of Gibi was not enough to feed otherwise. Therefore, in the process of plant growth, it is difficult to absorb phosphoric acid, which has already been changed to insoluble in the soil, so that the growth balance is not balanced, so that sufficient growth such as growth, overhaul, poor fruiting, falling fruit, malformation, heat, etc. is not achieved. Due to its low resistance to many pests, one of the main reasons for producing agricultural crops is due to a lack of phosphoric acid. Mostly, the fast-soluble water-soluble phosphate is fixed on the soil before it is absorbed from the roots when it is used as it is on the soil surface. The water-soluble phosphoric acid is insoluble and causes acidification of the soil. Since it is impossible to reach the roots and cannot be absorbed, the conventional fertilization of phosphoric acid has a problem in that a sufficient fertilization effect cannot be expected in the growth of crops.

Therefore, there is a drawback in that it does not supply enough phosphoric acid effectively during the growing period of the crop, which is a problem that the fertilization effect of sufficient phosphoric acid on the crop is not solved. It has been pointed out that it is not desirable in terms of labor and cost, but there was no clear solution.

It is an object of the present invention to provide an additional cost phosphate fertilizer composition and its manufacturing method which is easily insolubilized in the aerobic composition, the fertilizing effect is drastically reduced, and the fertilization of phosphoric acid is known to be impossible.

The additional cost phosphate fertilizer composition according to the present invention may be fermented by microorganisms native to soil fermented raw materials containing starch as 30 to 50% by weight of meat bone or fish meal and 10 to 20% by weight of sugar and residual amount. The obtained organic fermentation broth mixed with 0.001 to 0.003% by weight, phosphoric acid compound 35 to 55% by weight, Kali compound 15 to 35% by weight and a small amount (less than 7%) of water as a residual amount of 20 to 20 to 50 ℃ It comprises fermented product which has been fermented for 30 hours.

The organic material may be selected from the group consisting of meat bone meal, rice bran, fish meal or a mixture of two or more thereof.

The production method of the additional cost phosphate fertilizer composition according to the present invention, (1) 30 to 50% by weight of meat bone or fish meal and 10 to 20% by weight of sugar and the remaining amount is grown natively in the soil collected fermentation raw material containing starch Fermentation by a microorganism to make, followed by compression to obtain a fermentation broth; (2) 0.001 to 0.003% by weight of the fermentation broth obtained by pressing the fermentation product obtained in the first fermentation step, 35 to 55% by weight of phosphate compound, 15 to 35% by weight of kali compound and a small amount (less than 7%) A second fermentation step of mixing organic materials including water and fermenting them at 50 to 70 ° C. for 20 to 30 hours; And (3) a post-treatment step of drying and packaging the fermentation product obtained in the second fermentation step.

The first fermentation step may be heated fermentation for 12 to 36 hours at a temperature of 60 to 70 ℃.

In addition, the first fermentation step may be room temperature fermentation for 60 to 90 hours at room temperature.

Hereinafter, the present invention will be described in detail with reference to specific examples.

The additional cost phosphate fertilizer composition according to the present invention may be fermented by microorganisms native to soil fermented raw materials containing starch as 30 to 50% by weight of meat bone or fish meal and 10 to 20% by weight of sugar and residual amount. The obtained organic fermentation broth mixed with 0.001 to 0.003% by weight, phosphoric acid compound 35 to 55% by weight, Kali compound 15 to 35% by weight and a small amount (less than 7%) of water as a residual amount of 20 to 20 to 50 ℃ Characterized in that it comprises a fermented product fermented for 30 hours.

The fermentation broth is obtained by fermenting a fermentation material comprising starch as meat bone meal or fish meal 30 to 50% by weight, sugar 10 to 20% by weight, and the balance using microorganisms native to the soil, the present invention specifically In the illustrative example, microorganisms native to the soil collected from the tidal flats of the Taean Peninsula in Korea and microorganisms native to the foliar soil collected from the middle of Gayasan Daegu Metropolitan City in Korea were used. The method of using microorganisms is not specifically screened for microorganisms, and the microorganisms can be directly fermented by mixing soil grown by the microorganisms with the fermentation raw materials or by embedding them in a foliar soil in a state where a wooden box containing the fermentation materials is covered with a common blank paper. It was used for fermentation of fermented raw materials.

The fermentation broth was originally fermented by microorganisms present in the soil, and there are a large amount of aerobic and anaerobic fermentation bacteria in them. It is converted into a state, and in particular, after fertilization, the insoluble phosphate compound is decomposed over time by moisture in the soil, so that the growing crops can be easily absorbed. In the present invention, the fermentation bacteria were not screened and identified, and in general, the microorganisms native to the soil in Korea were used for fermentation as it is, and the fermentation bacteria were not used as a bacteriologically separated sugar (disaccharide) or starch. Sugars such as (polysaccharides) function as essential nutrients for the cultivation of microorganisms, and in particular, sugars such as sugar or starch, by themselves, not only create conditions for fermentation microorganisms to grow and grow, but also alcohol or organic acids when fermented. It is easy to use because it does not become corrupt as it becomes a kind.

When the fermentation broth is included in less than 0.001% by weight, there may be a problem in that the effectiveness of the decomposition of insoluble phosphoric acid by the fermentation broth becomes too small, so that the application of sufficient phosphoric acid does not appear, on the contrary, exceeding 0.003% by weight In particular, it is only a waste of fermentation broth without any significant difference in the effectiveness of phosphoric acid.

The phosphate compound is a compound for supplying phosphoric acid to a growing crop, which is the same as or similar to that included as a phosphate fertilizer in a conventional compound fertilizer, and can be easily understood by those skilled in the art as well as commercially available. It can be understood to be known enough to be used. Examples of such phosphate compounds include phosphates of Ca, Al and Fe, organic phosphate compounds, and phosphates adsorbed on hydroxide type atomic groups of Al and Fe (AlOH-, AlOH2, FeOH-, FeOH2, etc.). When the phosphoric acid compound is included in less than 35% by weight, there may be a problem that the growth is inhibited due to the lack of phosphoric acid compound, the lack of phosphoric acid as a bulk element, on the contrary more than 55% by weight is one of the other mass elements The relative lack of phosphorus compounds may also lead to problems with growth inhibition.

The kali compound is also a compound for supplying kali to a growing crop, and is the same or similar to that contained as a calcibis ingredient in a conventional compound fertilizer, etc., which can be understood by those skilled in the art and can be easily purchased as well as commercially available. It can be understood to be known to the extent possible. The form of such a kali compound is mainly a water-soluble salt, and the types of salts are chlorides, sulfates, nitrates, carbonates, phosphates, ie, potassium chloride (KCl), sulfuric acid (K2SO4), and other fertilizers. When the Kali compound is included in less than 15% by weight, there may be a problem that the growth is inhibited due to lack of Kali compound, lack of Kali as a large element, on the contrary more than 35% by weight is one of the other mass elements Relative shortage of phosphorus phosphate compounds may also lead to problems with growth inhibition.

The organic material may be selected from the group consisting of meat bone meal, rice bran, fish meal or a mixture of two or more thereof. However, the organic materials are not limited only to the meat bone meal, rice bran or fish meal as described above, and it can be easily understood by those skilled in the art that the by-products obtained in the conventional concentrated aquatic product processing process can be used. The organic material is also decomposed by the fermentation broth as described above and supplied to the crop as nutrients, and serves to fertilize the soil. The organics contain a small amount (less than 7%) of water as the remainder. If the amount of the organic matter is insufficient, there may be a problem that the lack of soil fertilization, etc., or the lack of other organic components. The water contained in the organic matter is naturally contained in a small amount even when using a conventional dry matter or only a small amount of water is added as needed, and can be understood as a water content of an acceptable level in conventional fertilizer production. Can be.

The manufacturing method of the additional cost phosphate fertilizer composition according to the present invention, (1) 30 to 50% by weight protein, such as meat bone meal or fish meal, 10 to 20% by weight sugar and the remaining amount of the fermentation raw material containing starch is collected in a natural state Fermentation by microorganisms native to soil, followed by compression to obtain a fermentation broth; (2) 0.001 to 0.003% by weight of the fermentation broth obtained by pressing the fermentation product obtained in the first fermentation step, 35 to 55% by weight of phosphate compound, 15 to 35% by weight of kali compound and a small amount (less than 7%) A second fermentation step of mixing organic materials including water and fermenting them at 50 to 70 ° C. for 20 to 30 hours; And (3) a post-treatment step of drying and packaging the fermentation product obtained in the second fermentation step.

The first fermentation step is an initial fermentation step to expand and culture the microorganisms in order to use the microorganisms native to the soil, and to ferment them again with ordinary phosphate compounds and kali compounds. The microorganisms used in the first fermentation step are not screened and identified separately, but are mixed or contacted with the fermentation material directly or indirectly so that the microorganisms are expanded and cultured as the fermentation raw materials are fermented. And anaerobic fermentation bacteria are mixed with the phosphate compounds and kali compounds and used as a method of fermentation again.

In the second fermentation step, the fermentation broth obtained in the first fermentation step is not screened and identified separately, but is fermented again with common phosphoric acid compounds and kali compounds to obtain fermented fertilizer. Such a natural fermentation method is to use the fermentation principle using the microorganism as it is naturally obtained, such as in the manufacture of conventional compost, the production of meju and fermented foods such as kimchi, which are widely known, and those skilled in the art as described above It can be understood, of course, that it can be carried out as is based on the detailed description to produce a predetermined additional cost phosphate fertilizer composition described in the present invention.

The first fermentation step may be heated fermentation for 12 to 36 hours at a temperature of 60 to 70 ℃. Warm fermentation can be easily understood by those skilled in the art to warm the fermentation mixture to promote fermentation to promote microbial growth. If heated to less than 60 ℃ in the fermentation, there may be a problem that the promotion of fermentation is insufficient, rather than 70 ℃ may be a problem that the fermentation promotion is also insufficient due to inactivation by heating of microorganisms. have.

In addition, the first fermentation step may be room temperature fermentation for 60 to 90 hours at room temperature. Room temperature fermentation can also be easily understood by those skilled in the art. If fermentation is less than 60 hours at room temperature fermentation, there may be a problem that the promotion of fermentation is insufficient, more than 90 hours may cause problems such as rancidity.
