いた。2. Description of the Related Art Lime-nitrogen fertilizer is a slow-release fertilizer containing calcium cyanamide as a main component and also has a pesticide effect, and has been used for many years. However, the slow-release effect of lime nitrogen fertilizer is easily affected by soil, and the pesticide effect was developed within 1-2 days after application and continued for about a week after that, but it was difficult after that. , It was necessary to apply fertilizer in several times, which made the agricultural work busy. Therefore, the appearance of a lime-nitrogen fertilizer, which can adjust the fertilization effect, for example, the period until nitrification, and the pesticide effect, for example, sustained release of cyanamide, without waiting for the influence of soil and the like, has been awaited.

（特公昭４０−２２８９６号公報）。Conventionally, it has been known that the fertilizer is made into granules and the surface thereof is coated with a resin or the like in order to adjust the solubility of the fertilizer components and achieve the slow release effect (Japanese Patent Publication No. 60-304.
No. 0, Japanese Patent Publication No. 60-21952, Japanese Patent Publication No. 2-
However, all of these target fertilizers relate to urea, ammonium sulfate, ammonium nitrate, potassium chloride, etc., and not lime nitrogen fertilizers. Regarding the lime nitrogen fertilizer, it is only disclosed that the surface of a granular one is coated with sulfur in order to prevent weathering (Japanese Patent Publication No. 40-22896).

には至っていない。Granular lime-nitrogen fertilizer coated with sulfur is manufactured with consideration so as not to suppress elution, so when the soil is different, the slow-release and pesticide effects are adjusted while maintaining the fertilization effect. Often difficult to do. Also,
Some efforts have been made, such as granulating lime nitrogen fertilizer and coating the surface with a thermoplastic resin or a rubber polymer, but simply coating it has not been sufficient to adjust the hydrolysis rate. .

ることが困難であった。That is, the above-mentioned coating method is intended to substantially reduce the surface area of lime nitrogen in the portion in contact with water when calcium cyanamide in lime nitrogen fertilizer is hydrolyzed. When the hydrolysis of lime nitrogen was started, its effect was lost, and it was difficult to adjust the slow release effect and pesticide effect while maintaining the original fertilizing effect of lime nitrogen fertilizer.

得られないことが未解決であった。[0006] Therefore, the present applicant delayed the hydrolysis rate of lime nitrogen by the presence of a specific substance, so that the fertilizing effect and the pesticide effect could be adjusted in many soils, and the handling property was excellent. A granular lime nitrogen composition was previously proposed. However, it has been unsolved that the effect of delaying hydrolysis of the lime nitrogen composition cannot be sufficiently obtained in the soil containing a large amount of soil colloid.

損なわせない限り含有させることができる。As the lime nitrogen used in the present invention, generally available lime nitrogen suffices, calcium cyanamide (CaCN 2 ) being the main component, quick lime (CaO), slaked lime (Ca (OH) 2 ) and carbon. Various compositions having (C) as an auxiliary component are known, and any of them can be used. Further, the lime nitrogen can contain a plurality of fertilizer components such as a phosphoric acid component, a potassium component, and other trace components as long as the purpose of delaying the hydrolysis rate of lime nitrogen is not impaired.

Ammonium ion (NH
4 +), nitrate ion (NO 3 - is known to vary in). Thus, in soil, lime nitrogen is hydrolyzed to release cyanamide, but in general, the hydrolysis ends in 1-2 days, and the cyanamide produced further changes to urea, etc., The pesticide effect ends in about a week. Therefore, if the hydrolysis rate of lime nitrogen is delayed to slow the generation rate of cyanamide, the subsequent generation rate of urea and the like can also be delayed, so that the fertilization effect can be prolonged and extended.

Furthermore, since there is no medicinal damage and the fertilizing effect continues for a long time, it is possible to use the fertilizer not only as a basic fertilizer but also as an additional fertilizer for a plurality of doses at a time.

It is preferable to add it by spraying, dipping, etc., and roll it. According to the latter granulation method, the proportion of the water-repellent substance in the granulated substance is higher in the vicinity of the surface than in the central part, so that the amount of the water-repellent substance used can be reduced and the reduction of fertilizer components can be prevented. be able to.

Also, when a large amount of quick lime is contained in lime nitrogen, the volume expansion when quick lime hydrates may cause the granulated material to collapse and become powdered. It is desirable to mix a small amount and to dissolve some or all of quicklime in lime nitrogen. Urea can also be used as a binder.
