如くいわれている。2. Description of the Related Art In recent years, the term "environmentally conserving agriculture" has been a word of success, and a shift from conventional fertilizer-intensive agriculture to low-input, sustainable agriculture has been called for. Against this background, chemical fertilizers, especially generalized chemical fertilizers, are quick-acting fertilizers, but are quickly nitrified and leached to increase the nitrate nitrogen content in groundwater and become one of the ozone depleting substances. It is said to be the cause of environmental pollutants because it produces nitrous oxide.

In addition, dicyandiamide is known as an excellent nitrification inhibitor, and fertilizers to which dicyandiamide is added are used.However, in those fertilizers containing dicyandiamide, dicyandiamide is denatured during the manufacturing process, or obtained. There were problems such as the slow-release effect of dicyandiamide in fertilizers and the ability to inhibit nitration were not sufficient.

ことを見出し、本発明を完成させるに至った。SUMMARY OF THE INVENTION The present invention provides a fertilizer which continuously supplies nutrients corresponding to the amount of crop absorbed from the viewpoint of fertilization technology for reducing environmental load. A fertilizer that does not accumulate excess nutrients in the soil. Various studies were conducted with the aim of developing a sigmoid-type nitrogen-eluting fertilizer. The present inventors used a sigmoid-type biodegradable lime-nitrogen metabolite as a base fertilizer, focusing on dicyandiamide in particular, coexisting this with an organic substance, and granulating the fertilizer with other fertilizer raw materials. By doing so, it has been found that denaturation of dicyandiamide in the production process can be prevented, and the sustainability of the nitrification-inhibition ability when fertilized can be increased, and the present invention has been completed.

By enhancing the ability of fertilizers to control nitrification, the nitrification of not only fertilizer-derived nitrogen but also soil-derived nitrogen is suppressed, and the loss and denitrification of mineralized nitrogen is suppressed, and the nitrogen utilization rate is increased. The effect is expected.

にほとんどジシアンジアミド態としては残らない。However, dicyandiamide is quantitatively converted to guanylurea when a temperature is applied under acidic conditions, and is further converted to guanidine or melamine under severe conditions. For this reason, under normal granulation conditions, denaturation of dicyandiamide is inevitable. Although dicyandiamide has a high resistance to metamorphosis near neutrality as in the case of advanced chemical formation, it is still unavoidable that metamorphosis occurs during a drying process that requires a high temperature. In addition, in low-temperature formation with many acidic regions, generally, almost no dicyandiamide remains.

推定される。However, the present inventors have found that when a fertilizer raw material containing dicyandiamide and an organic substance is used, even under ordinary fertilizer production conditions under which dicyandiamide is liable to be transformed, the dicyandiamide can be converted to a low-grade chemical at about 70-90% of the original amount. It was found that most of them remained in advanced chemical formation. This is presumed to be because the lipophilic dicyandiamide is wrapped in organic matter and is less susceptible to acid-catalyzed hydrolysis reactions.

推定される。Further, the present inventors have found that the ability to inhibit nitric acid formation derived from dicyandiamide is enhanced by the combined use with an organic substance, and that the rapid nitrification formation after mild mineralization of an organic substance can be suppressed. I found it. This is also presumed to be due to the interaction between dicyandiamide and the organic matter.

能である。Hereinafter, the chemical fertilizer containing organic matter of the present invention will be described. The fertilizer raw material used in the present invention contains dicyandiamide and an organic substance, and may further contain a commonly used fertilizer component. The added amount of dicyandiamide is important because if it is added too much, there is a risk of damaging the crop. Usually, the nitrogen content of dicyandiamide is 0.01 to 25% by weight based on the total nitrogen in the chemical fertilizer of the present invention. , Preferably within the range of 1 to 20%.

Examples of such organic substances include, for example, animal and plant organic fertilizers such as fish cake, steamed bone meal, dried blood meal, rapeseed oil cake, and soybean oil cake, fermented dry soil fertilizer, sludge fertilizer, and organic waste fertilizer such as dried cell fertilizer. Composts such as cow dung compost, pig dung compost, and bark compost can be mentioned, and one or more of these can be selected and used.

のが挙げられる。[0014] There is a negative correlation between the usage ratio of the organic substance and the conversion rate of dicyandiamide. As the usage amount of the organic substance increases, the conversion rate decreases and the residual rate of dicyandiamide increases. The general use amount of the organic matter is 5% to 80%, preferably 10%, based on the weight of the chemical fertilizer of the present invention.
~ 70%. If it is less than 5%, most of the dicyandiamide is denatured, and if it exceeds 80%, the granulation ratio tends to decrease. As a fertilizer raw material used in the present invention, a commonly used fertilizer component can be used in addition to dicyandiamide and organic substances as appropriate. Examples of such fertilizer components include the following.

0.18 kg of urea, 0.67 kg of ammonium sulfate, 0.16 kg of dicyandiamide, 0.81 kg of salted water, 1.78 kg of lime superphosphate and 0.12 kg of gypsum are thoroughly mixed in a pan granulator, and water is supplied appropriately. Granulation was carried out. After the obtained granules were dried in the sun, dicyandiamide in the fertilizer was analyzed by liquid chromatography. As a result, the dicyandiamide content in the fertilizer was 0.131 kg, and the residual ratio was 82%. The results of Examples 2 and 3 and Comparative Examples 2 and 3 show that although there is not much difference as in the case of low-grade chemical conversion, even in the case of advanced chemical conversion, the addition of an organic substance increases the residual ratio of dicyandiamide.
