Description

The present invention relates to a soil conditioner that uses chicken manure, which is a social problem because it occurs in large quantities in poultry farms and the like.

  Conventionally, poultry manure is generated in large quantities in poultry farms and the like, and this has become a social problem over its disposal. However, chicken manure contains organic compounds that are useful for agricultural crops and is a soil conditioner. It is effectively used as a fertilizer. In order to use chicken manure as a soil conditioner or fertilizer, it is naturally dried by the sun, forcibly dried by using fuel, or further subjected to a fermentation treatment.

  And in order to use chicken manure as a soil improvement and fertilizer, chicken manure is naturally dried by the sun as it is, or by forced drying by using fuel, bad odor due to spoilage etc. occurs, Even if it takes a lot of time to finish the process, the cost of the process is high, and even if it is subjected to a fermentation process, harmful gases may be generated by the fermentation. There are problems that it is difficult to produce a soil improver and fertilizer of stable quality because experience and technology accumulated over many years are necessary to control the fermentation, but various solutions have been achieved.

  For example, Patent Document 1 discloses a soil conditioner in which calcium salt and sulfuric acid are added and mixed with chicken dung, which is a main component, and granulated brown rice and a residue after decomposition of soybean enzymes are mixed. . Moreover, the soil improvement agent which mixed the humus soil with the soil improvement agent is also disclosed.

Japanese Patent No. 4392542

  However, the soil improver described in Patent Document 1 described above is used although the conventional problem that it is difficult to produce a bad odor due to spoilage or the like and to produce a soil improver having a stable quality is used. The effect of increasing the number of general viable bacteria in the soil was not sufficient. In other words, from the standpoint that industrial waste, which is a large amount of poultry manure generated at poultry farms, can be effectively used as a management resource called a soil conditioner, there is a merit for operators of poultry farms, etc. From the viewpoint of the person skilled in the art, the soil improver described in Patent Document 1 is less attractive for the effect as a soil improver, for example, the effect of increasing the number of viable bacteria in the soil used, and further improvement has been demanded.

  In addition, the soil conditioner described in Patent Document 1 has been experimented on the increase in the number of general viable bacteria for a soil conditioner mixed with humus, which is generally known as a nutrient. There was a need for a high soil conditioner.

  Therefore, in the present invention, the generation of malodors due to processing of chicken manure and the quality can be stabilized, but the effect as a soil conditioner, for example, the effect of increasing the number of general viable bacteria in the soil to be used is high. An object is to provide a soil conditioner.

  That is, the soil conditioner according to the present invention includes at least any compound of calcium silicate or calcium carbonate, and chicken dung mixed with sulfuric acid, granulated brown rice, soybean enzymatic decomposition residue, amino acid, It is a soil improvement agent characterized by containing.

  And it is said soil improving agent by which 0.005-10 weight part of said amino acids are mix | blended with respect to 100 weight part of agents containing the said chicken dung, the said brown rice, and the said soybean enzyme degradation residue.

  And said amino acid is said soil improving agent containing at least any one of glutamic acid, arginine, aspartic acid, phenylalanine, or cystine.

  If configured in this way, the generation of bad odor due to processing of chicken manure and the quality can be stabilized, but the effect as a soil conditioner, for example, the effect of increasing the number of general viable bacteria in the soil to be used is high. can do.

  As described above, according to the present invention, as described above, the generation of bad odor due to processing of chicken manure and the effect as a soil improver while being able to stabilize the quality, for example, the number of viable bacteria in the soil to be used The effect of increasing can be increased.

  Hereinafter, the embodiment regarding the soil improvement agent which concerns on this invention is described in detail. In addition, the description which shows the range in description contains an upper limit and a minimum.

  The soil conditioner according to the present invention contains at least a compound of either calcium silicate or calcium carbonate, and chicken dung mixed with sulfuric acid, granulated brown rice, soybean enzyme degradation residue, and amino acids. For example, it is manufactured as follows.

  The chicken manure used in the present invention can be recovered and used without processing anything that has been generated in large quantities in a poultry farm or the like. Calcium silicate and calcium carbonate are used to granulate chicken dung, and at least one of these compounds may be mixed, but both may be mixed. This compound or these compounds are mixed in an amount of 10 to 20 parts by weight per 100 parts by weight of chicken manure.

  Furthermore, sulfuric acid is mixed to react with the basic compound in chicken manure to neutralize it. Commercially available concentrated sulfuric acid can be used, and diluted sulfuric acid diluted with water. Sulfuric acid can also be used. This sulfuric acid is mixed in an amount of 3 to 15 parts by weight with respect to 100 parts by weight of chicken manure.

  Thus, at least any compound of calcium silicate or calcium carbonate and sulfuric acid are mixed with chicken manure, but at least either of the compound of calcium silicate or calcium carbonate and sulfuric acid is first of all. Although it may be mixed with chicken manure or simultaneously, it is preferable to add sulfuric acid first in order to effectively remove malodor. When sulfuric acid is added to chicken dung and mixed well, at least one compound of calcium silicate or calcium carbonate is mixed, and the viscous form of chicken dung changes into a dumpling lump. Furthermore, the chicken dung which became dumpling-like lump is granulated by, for example, applying it to a grinder or a granulator.

  The pulverized brown rice used in the present invention only needs to be obtained by pulverizing the brown rice into a powdery or granular form, and is limited to those pulverized by high-heat roasting of the brown rice used in the following examples. Is not to be done. This granulated brown rice is mixed in an amount of 1 to 3 parts by weight with respect to 100 parts by weight of chicken manure mixed with at least one of the compounds of calcium silicate or calcium carbonate and sulfuric acid. In addition, the soybean enzymatic degradation residue is fermented with Aspergillus oryzae, immediately after enzymatic digestion and extract extraction, etc. are mixed, and at least one of the above compounds of calcium silicate or calcium carbonate, and 1 to 3 parts by weight is mixed with 100 parts by weight of chicken dung mixed with sulfuric acid.

  And the amino acid used in this invention is an organic compound provided with the functional group of both an amino group and a carboxyl group in a molecule | numerator, and is a raw material which contributes greatly to the increase in the general living microbe in soil. Examples of such amino acids include alanine, arginine, asparagine, aspartic acid, cysteine, glutamine, glutamic acid, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine. Preferred are amino acids, and cystine, which is a dimer obtained by dehydrating condensation of an amino group and a carboxyl group of these amino acids. Of the above, glutamic acid, arginine, aspartic acid, phenylalanine, cystine and the like are more preferable. These amino acids can be used alone or in combination of two or more. The amino acid is preferably added in an amount of 0.005 to 10 parts by weight, and 0.01 to 5 parts by weight based on 100 parts by weight of the agent containing the chicken dung, the brown rice, and the soybean enzyme degradation residue. More preferably. If the amount is within this range, the number of viable bacteria in the soil can be greatly increased compared to the conventional method, and even if more amino acids are added, the effect tends to decrease. The increase in cost due to can also be suppressed. These liquid or solid amino acids may be mixed as they are, but once dissolved in water, at least any compound of calcium silicate or calcium carbonate, and chicken manure mixed with sulfuric acid, You may impregnate and mix the agent containing a granulated brown rice and a soybean enzyme degradation residue.

  In addition, various additives can be added to this invention as needed within the range which does not affect the increase in the number of general viable bacteria in soil.

  As described above, the soil conditioner containing various components is granulated and manufactured. The granulated soil conditioner may be pelletized by a tableting machine or the like.

  Next, the preferable Example about the soil improvement agent of this invention is given, and the result measured about the increase in the number of general viable bacteria at the time of using the soil improvement agent is shown.
