Description

Organic ferment complex fertilizer manufacturing process

The present invention relates to a method for preparing an organic fermented compound fertilizer which helps plant growth by restoring contaminated soil, and a composite fertilizer prepared by the method, and more particularly, quicklime, natural fermentation agent, and biodegradable organic matter. Mixing step of mixing the material; It relates to a method for producing an organic fertilizer composite fertilizer comprising a fermentation step of heating the mixed material, stirring and fermentation, and a composite fertilizer prepared by the method.

Frequent use of chemical fertilizers in crop cultivation has gradually acidified the soil and ruined cropland. In addition, industrial development has made our lives convenient and developed, while the environment is rapidly being destroyed. The huge increase in factories, oils and chemicals used in the military, and also the pollution of the coast due to oils and chemicals used in military units, oil accidents, soils near oil depots and gas stations, etc. are gradually increasing. The death of fish due to such pollution and the increase of wasteland due to acidification or oilification of the soil will be more deadly in Korea where resources are scarce.

As a method for restoring the contaminated soil, the polluted soil of the relevant area is periodically sprayed and water is periodically sprayed to stir the contaminated soil and the contaminant is used as a carbon source. And a method of adding a surfactant that slightly promotes microbial activity to the soil, or a method of adding chemical fertilizer as a method of enhancing the microbial activity by dissolving contaminants in the organic solvent somewhat. have.

However, these methods slow the decomposition of contaminants, resulting in longer soil restoration times and less efficiency, and chemical surfactants can desorb pollutants, but chemical surfactants may cause further contamination. There is a problem, and the method of adding a chemical fertilizer for the cultivation of microorganisms has a problem of reducing the vitality of the soil microorganisms and weakening the function of the soil.

Accordingly, the present inventors have repeatedly experimented to solve the above problems, when the fermented organic fermentation compound fertilizer including natural fermentation agent, biodegradable organic matter and quicklime is used, the contaminated soil is quickly restored to grow plants. The present invention was confirmed to be effective.

Accordingly, an object of the present invention is to provide a method for preparing an organic fertilizer composite fertilizer in which there is no secondary and tertiary pollution while activating microorganisms of contaminated soil.

It is also an object of the present invention to provide an organic fermentation compound fertilizer that is effective for plant growth because the soil is quickly restored without secondary and tertiary pollution.

The present invention for achieving the above object is a material mixing step of mixing 5 to 60% by weight of a natural fermentation agent, 30 to 70% by weight biodegradable organic material and 5 to 30% by weight quicklime; It provides a method for producing an organic fertilizer composite fertilizer comprising a fermentation step of fermenting the mixed material by heating and stirring.

In another aspect, the present invention provides an organic fermentation compound fertilizer prepared by the above production method.

The natural fermentation agent used in the present invention is characterized in that the mushroom medium waste sawdust. The mushroom medium waste sawdust is a sawdust that is discarded after cultivating the mushroom, and not only plays a role in controlling moisture of the target substance as a sawdust, but also activates the decomposition and fermentation of microorganisms due to the mushroom spawn contained in the sawdust. In addition, the fermentation time is shorter than when using an artificial fermentation agent, it is beneficial to the soil even when used in the soil, there is a cost advantage.

As the natural fermenter, mushroom yeast waste sawdust may be used by further adding waste yeast as a natural fermenter. Waste yeast means, for example, yeast bacteria left over from beer in a beer factory. Waste yeast is not only rich in protein and other nutrients, but yeast is itself a microorganism that benefits the soil. Let it be. Therefore, when used together with mushroom medium waste sawdust as a natural fermenter, it reduces the fermentation time.

The biodegradable organic material of the material mixing step is characterized in that the waste protein source and various plant and animal waste. That is, as the biodegradable organic material, various food wastes and wastes such as feces and fish and shellfish wastes may be mixed or used. It is effective in restoring and improving the soil by treating wastes and at the same time increasing the supply of protein and carbohydrates at low cost. As a source of protein, it is also possible to add and use Busy.

Quicklime (CaO) in the material mixing step is used to replenish the basic components to alkalinize the soil.

The fermentation step is heated to 45 ~ 50 ℃ the mixture material mixed in the material mixing step is aged for 15 days ~ 1 month and then stirred it. At this time, the humidity of the stirred material is 60 ~ 65%, pH is 6 ~ 6.5.

The first aging and stirred the material is heated to 60 ~ 70 ℃ aging for 15 days ~ 1 month and then stirred it. At this time, the humidity of the second aged and stirred material is 55 ~ 60%, pH is 6.5 ~ 7.

The secondary aging and stirred material is heated to 70 ~ 80 ℃ aged for 15 days to 1 month and then stirred it. Humidity of the third aging and stirred material at this time is 50-55%, pH is 7.5-8.

The fermentation step proceeds while maintaining the moisture at 50-65% in the shady place to expand and reproduce the function of the effective microorganisms. By repeating the process of stirring after heating and aging three times, fermented evenly under different conditions so that the mixture is fermented and matured more effectively, thereby improving the quality of fertilizer and also suitable for use as a fertilizer. While controlling the content and acidity, product manufacturing time can be shortened by more than one month in general compared to the mixed fermentation of ingredients.

The fermented fermented material is used to grind to a particle diameter of 1 ~ 15mm is also convenient when using the actual fertilizer, as well as easy to mix the fertilizer with the soil as follows.

Non-contaminated soil is blended into the fermentation mixture obtained through the fermentation step. The reason for mixing uncontaminated soil is that more than 100 million soil microorganisms live in 1 g of healthy soil, and more than 3,000 species of soil microorganisms are inhabited. It is to strengthen the power. 60 to 90% by weight of the fermentation mixture and 10 to 40% by weight of the soil are mixed with respect to the total weight of the fertilizer to be prepared.

It is aged at 30-40 ℃ for 15 days ~ 1 month. The fermentation process allows the microorganisms contained in the fermentation mixture to be effectively propagated in the mixed soil.

Hereinafter, the manufacturing method of the present invention will be described in detail with reference to Examples.

As a result of the experiment, when the organic fermented fertilizer complex fertilizer of the present invention was added 60% by weight, the grass grew 2.3 cm after 28 days, and the organic fermented compound fertilizer of the present invention 50% by weight. After 28 days, the grass grew 2.5 cm, and when the organic fermented fertilizer complex fertilizer of the present invention was added 40% by weight of the total weight, the grass grew 3.5 cm, and the organic fermented product of the present invention. When the compound fertilizer was added 30% by weight relative to the total weight it can be seen that the grass grew 2.0 cm after 28 days.

On the other hand, the soil did not grow at all, and when using the organic fermented fertilizer of the present invention, even when 40% by weight, the ratio of grass growth, was applied to ordinary compost or urea fertilizer after 28 days Was 0.7 cm and 0.3 cm, respectively, and it can be seen that the organic fermented compound fertilizer of the present invention showed a similar effect as when used for 7 days.

On the other hand, if the grass was grown without fertilizer on uncontaminated soil, it can be seen that after 28 days 2.3cm grew.

Therefore, when the organic fermented fertilizer complex fertilizer of the present invention is used in contaminated soil, it can be seen that the contaminated soil is improved and the grass grows, rather, the grass grows better when grown in uncontaminated soil. Can be.

Experimental Example 2

For the contaminated soil in Experimental Example 1, the state change of the soil was observed 28 days after and before using the organic fermentation compound fertilizer of the present invention. For this purpose it was observed using 60% by weight of soil contaminated with petroleum (light oil) + 40% by weight of the organic fertilizer composite fertilizer of the present invention.

division PH of the soil Hexadecane (C ₁₆ H ₃₄ ) Before using organic fermented compound fertilizer of the present invention (when polluted soil is 100% by weight) 4.9 2000 ppm 60% by weight of contaminated soil + 40% by weight of organic fertilizer compound fertilizer of the present invention 7.5 40 ppm

As a result of the experiment, when the pH was low to 4.9, the acidity was severe, but after 40% by weight of the organic fermented fertilizer of the present invention, it can be seen that the soil was alkalized to pH 7.5.

It can also be seen that the hexadecane level of petroleum has changed from 2000 ppm to 40 ppm.

The changed value is almost similar to the general soil uncontaminated, and therefore, it can be seen that the organic fermentation compound fertilizer of the present invention has an effect of quickly restoring the contaminated soil in only one.

Experimental Example 3

Using the organic fermentation compound fertilizer and the conventional compost and urea fertilizer of the present invention in the soil before pollution, each of 10 cabbages were cultivated, and while 10 cabbages were also grown in the soil restored through Experimental Example 2, The average growth length of Chinese cabbage was measured for each period. The results are shown in Table 3.

division 4 days (cm) 7 days (cm) 14 days (cm) 21 days (cm) 28 days (cm) 100% by weight of soil before pollution 0.5 1.3 2.1 2.8 3.5 60% by weight of soil before contamination + 40% by weight of urea fertilizer 0.7 2.0 3.0 4.3 5.1 60% by weight of soil before contamination + 40% by weight of conventional compost 0.6 1.8 2.0 3.8 6.0 60% by weight of soil before pollution + 40% by weight of organic fermented compound fertilizer of the present invention 0.8 2.1 4.3 8.0 12.0 100% by weight of restored soil 0.7 1.7 3.9 7.0 10.5

When the Chinese cabbage was grown using only soil before pollution, it grew only 3.5cm after 28 days. When urea fertilizer or normal compost was used on soil before pollution, it grew 5.1cm and 6.0cm after 28 days. Can be seen. On the contrary, when the cabbage was grown using the organic compound complex fertilizer of the present invention in the soil before the contamination, the cabbage was grown by 12.0 cm, and the cabbage was recovered after restoring the contaminated soil using the organic fermentation compound fertilizer of the present invention. In the case of cultivation, it can be seen that after the growth of 10.5 cm.

That is, in the case of cultivating cabbage in the general soil before contamination, the cabbage was hardly grown even after 28 days, and even in the case of using ordinary compost or urea fertilizer, it grew more than using only soil, but compared to these When the Chinese cabbage is grown using the organic compound fertilizer in the soil before pollution, it can be seen that the cabbage has grown significantly, and even when the soil is restored using the organic compound compound fertilizer of the present invention, the present invention is applied to the soil before pollution. It can be seen that the cabbage was grown to a similar extent as when grown using the compound fertilizer.

Therefore, the compound fertilizer of the present invention not only has a significantly better effect as a fertilizer than a conventional chemical fertilizer or compost, but also when used in a contaminated soil, the contaminated soil of the present invention, which remains at the same time as the contaminated soil, is grown. You can see that it plays a very good role.

As described above, the present invention provides a method for preparing an organic fermentation compound fertilizer and an organic fermentation compound fertilizer prepared by the method by mixing and fermenting a natural fermentation agent with a biodegradable organic material and quicklime. As it is shortened, the polluted soil is quickly restored without the secondary and tertiary pollution. Also, it is harmless to the human body, and the plant growth is faster than that of the conventional fertilizer. It is possible to prevent, and is an effective invention when cultivating plants using pots in apartments or houses as well as farmland.
