ることのできる石灰窒素が望まれていた。2. Description of the Related Art Lime nitrogen 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 fertilizer effect may be affected by the soil, and the pesticide effect appears within 1-2 days after application and continues for about one week, but no further effect could be expected. Therefore, there has been a demand for lime nitrogen capable of adjusting the fertilizer effect, that is, the prolongation of the period of ammonification / nitration and the pesticide effect, that is, the prolongation of the elution period of cyanamide.
【0003】そこで、カルシウムシアナミドが尿素に変

10−297985号公報)。Therefore, an invention relating to a lime nitrogen composition in which a modifier that delays the hydrolysis reaction in which calcium cyanamide is converted into urea is added to lime nitrogen has been proposed (JP-A-10-297985).

るということは、この改質石灰窒素は緩効性肥料のうち
の遅効性肥料(シグモイド型肥料)に分類される。In this lime nitrogen composition, the rate of hydrolysis of calcium cyanamide is suppressed, so that the elution concentration of cyanamide per hour becomes constant at a low concentration, and the cyanamide existence time in soil is longer than that of conventional lime nitrogen. It has the advantage that the pesticide effect lasts for a long time. Also, regarding the fertilizer effect, since the hydrolysis rate of calcium cyanamide is suppressed, the subsequent time to change to ammonia nitrogen and nitrate nitrogen is delayed, and the fertilizer effect is prolonged. The fact that nitric acid is produced later than in conventional products means that this modified lime nitrogen is classified as a slow-acting fertilizer (sigmoidal fertilizer) among slow-acting fertilizers.

が不十分となる問題があった。However, when the above-mentioned lime nitrogen composition is applied to soil in which cyanamide is rapidly decomposed, the concentration of cyanamide in the soil becomes remarkably low, and it is against a certain organism having a high threshold (threshold) of cyanamide sensitivity. However, there was a problem that the pesticide effect was insufficient.

The purpose of the present invention is to provide granular fertilizer so that the concentration of the organism to be killed is reduced immediately after reaching the lethal concentration so that the fertilizer does not harm the organism.

Therefore, a small amount of water is mixed in advance with the lime nitrogen. However, it is desirable to hydrate part or all of the quicklime in the lime nitrogen. This operation is preferably performed on lime nitrogen for producing modified lime nitrogen granules.

It is preferable that after the granulation in step 1, a water-repellent substance is added in a tank such as a tumbling granulator and adhered to the surface of the granulated product. Adhesion of water-repellent substances to the surface of granules can be done by directly adhering, impregnating water-repellent substances once melted, melting and spraying water-repellent substances, emulsifying and adhering, impregnating powder such as talc. Means such as allowing them to adhere are adopted. After granulation, if necessary,

It is preferably 0 part. To obtain a slower effect, increase the ratio, and to obtain a faster effect, decrease the ratio. If it is less than 0.1 part, the modifying effect is small,
Further, when it exceeds 20 parts, the nitrogen component of the fertilizer is lowered, which is not preferable.

30 g was weighed, water was added so that the water content became 60% of the maximum water content, and the mixture was transferred to a 50 ml cylindrical container. 6 mg of mixed granular fertilizer was applied to the center of the soil as a nitrogen content. In order to prevent evaporation of water, the lid was covered with aluminum foil to the extent that it was not tightly sealed, and the cells were cultured in a 25 ° C. constant temperature chamber and sampled over time. Cyanamide was extracted from the sample soil using a 2% acetic acid solution. After filtering the extract with filter paper, the amount of cyanamide in the filtrate (that is, the amount of residual cyanamide) was measured by spectrophotometry using pentacyanoammineferroate as a color-forming reagent.

That is, when the amount of change in the residual amount of cyanamide in the sample per day is less than 3.5 mg cyanamide nitrogen / 100 g dry soil / day, the amount of change in the residual amount of cyanamide itself is regarded as the amount of cyanamide eluted from the fertilizer into the soil.
