Description of the Related Art In rice and wheat cultivation, harvesting by use of a combine is common, and straws, which are residuals, are discharged to a field with the harvesting. Some of the discharged straw is effectively used as livestock feed, litter and raw materials for processed straw and compost, but most of it is incinerated or left in the field. When incinerated, it wastes valuable organic resources and in some areas can cause serious traffic problems due to smoke. On the other hand, when straw is left in the field, the nitrogen content is low compared to the carbon content, and the ripening progresses slowly, causing nitrogen starvation due to insufficiently ripened straw, and the reduction of methane etc. in paddy fields It is known that a growth disorder such as a disorder caused by gas generated in the state and a promotion of phytotoxicity of the herbicide occurs.

On the other hand, it was an effective measure to some extent. However, the nitrogen source of the present invention is not lime nitrogen which is most involved in promoting ripening, but is ammonium sulfate or urea, which is liable to run off or volatilize. However, there was a drawback that it was difficult to exhibit. Also, in some paddy fields, no consideration was given to the often problematic damage caused by hydrogen sulfide.

Was something. However, since there was no effective granulation method, it had to be supplied in powder form, and although it had a high ripening promoting effect, there was room for improvement in terms of use such as dusting during spraying and inapplicability to mechanical spraying.

る。The granular organic matter maturation accelerating / soil improving material of the present invention (hereinafter, also referred to as the "product of the present invention") contains at least 20% by weight of lime nitrogen. When the amount of lime nitrogen is less than 20% by weight, the effect of promoting ripening is remarkably reduced. There is no particular upper limit on the proportion of lime nitrogen, but it is necessary to include urea as a binder in the product of the present invention. Therefore, the upper limit is desirably about 60% by weight. Particularly desirable is 30 to 50% by weight.

とすることによって、造粒が容易となる。The lime nitrogen used in the product of the present invention is 1% of total nitrogen.
Those having 9.0% by weight or more and an alkali content of 50% by weight or more are suitable, but not limited thereto. A calcareous substance such as quicklime, slaked lime and carbonated lime may be further added to this lime nitrogen to make the total nitrogen 10% by weight or more. By setting the particle size of lime nitrogen to 500 microns or less, granulation becomes easy.

This is performed by press molding such as tableting.

に分散する。The product of the present invention granulated using urea as a binder has the convenience of spraying, and after being sprayed, urea absorbs moisture from the soil and rapidly and extremely disintegrates, causing rainfall and tilling. Disperse promptly in each component by a slight stimulus.

１５ｋｇ、直径３ｍｍ程度の柱状体が望ましい。When the amount of urea is less than 10% by weight, the role as a binder is not sufficient, and it is difficult to mold the desired granulated product. The hardness and size of the granulated material can be appropriately adjusted, but for the purpose of the present invention, the crushing load is 5 to 5.
A columnar body of 15 kg and a diameter of about 3 mm is desirable.

おいては、尿素の割合は、造粒を行うのに必要最小限に
止めておくことが望ましく、２０重量％以内とした。On the other hand, the reason why the upper limit of urea is limited to 20% by weight is as follows. That is, there is generally an upper limit to the total nitrogen that can be contained in the ripening promoting material,
If the nitrogen content is higher than that required for straw ripening, the nitrogen may remain in the soil as inorganic nitrogen and adversely affect planting in the following year. Since urea itself contains nitrogen, its use has to relatively reduce the proportion of lime nitrogen, which is considered to be the most effective nitrogen source for organic matter maturation. Therefore, in the present invention, the ratio of urea is desirably kept to a minimum necessary for performing granulation, and is set within 20% by weight.

については特に制限はないが、１０重量％程度までが望
ましい。As described above, in the present invention, lime nitrogen and urea are used in combination as the nitrogen content, but the effect of promoting organic maturation is reduced. Therefore, in order to compensate for this decrease, in the present invention, a phosphate fertilizer is newly added to contain 0.5% by weight or more as a phosphoric acid content. The mechanism of action of phosphate fertilizer is unknown, but although the required amount is small, it is thought that supplementing phosphate, which is a nutrient source of microorganisms like nitrogen, will promote the effect of lime nitrogen. . The ratio of phosphate fertilizer is 0.5
If the amount is less than 10% by weight, the above effect becomes insufficient. The upper limit is not particularly limited, but is preferably up to about 10% by weight.

である。The phosphate fertilizer used in the product of the present invention is not particularly limited, and commercially available general phosphate fertilizer is used. Specific examples include yorin, calcined phosphorus manure, heavy burnt phosphorus, lime superphosphate, lime heavy superphosphate, etc., with yorin being particularly preferred. The reason is that yorin has the ability to neutralize the organic acids produced by the ripening of organic matter. This is because it contains silicic acid which may be applied for soil preparation in the field.

れずに粉化が大きくなる。Next, the product of the present invention contains the iron oxide-containing material in an amount of not more than 20% by weight (excluding 0) as iron oxide, whereby the above-mentioned obstacles caused by hydrogen sulfide can be reduced. If the iron oxide content is higher than the above,
In the granulation, the ratio of the iron oxide-containing material, which is a raw material having a large specific gravity, becomes excessive, so that a granular material having satisfactory strength cannot be obtained and powdering increases.

立つ。The iron oxide-containing material used in the product of the present invention includes bauxite, pyrite and mill scale, and particularly preferably steelmaking slag such as open hearth and converter furnace. These steelmaking slags contain not only the target iron oxide, but also silicic acid, lime, magnesia, phosphoric acid and other trace components which are considered to be effective for maturation promotion. It also helps neutralize the organic acids produced as the organic matter matures.

It is also possible to mix the fertilizer components which are considered to be effective for the maturation of organic substances, to dilute the concentrations of the components, and to granulate.
