酸苦土石灰粉とを混合して得られる新規な混合苦土石灰
肥料に関する。[Detailed description of the invention] (Industrial use!?) This invention is a novel mixed magnesia lime fertilizer obtained by mixing magnesia quicklime powder and carbonated magnesia lime powder, which have been recognized to have fertilizing effects. Regarding.

（従来例）従来より肥料として用いられる苦土石灰には大別して、
炭酸苦土石灰、苦土消石灰、苦土生石灰が存していたも
のであるが、それ等を製造段階にて予め混合したものは
存していなかった。(Conventional example) Magnesium lime, which has traditionally been used as fertilizer, can be roughly divided into:
Carbonate magnesium lime, magnesium slaked lime, and magnesium quicklime existed, but there was no one in which these were mixed in advance at the manufacturing stage.

然って施肥の際には単独で用いるか、あるいは施肥溝自
身の技術により撒布時において混合が行なわれていたも
のであった。Therefore, when applying fertilizer, either it was used alone, or it was mixed at the time of spreading using the technology of the fertilizing ditch itself.

（発明が解決しようとする問題点）然し乍ら、かかる従前例にあっては、単独で用いた場合
には、その肥料の性質、即ち、例えば苦土生石灰粉の速
効性、炭酸苦土石灰粉の遅効性と、その溶解速度が相違
し、そのため、慟布時期を夫々異にする必要が生じたり
、撒布肥料のかたより等を生じた。又、速効性肥料と遅
効性肥料を撒布時に混合するような場合には、混合され
た肥料自体にかたよりが生じたり、その混合比率等熟練
者に依る必要があった。(Problems to be Solved by the Invention) However, in such conventional precedents, when used alone, the properties of the fertilizer, i.e., the fast-acting properties of magnesia lime powder, the quick-acting properties of carbonated magnesia lime powder, etc. The slow release properties and dissolution speeds of these methods differed, which led to the need to apply the fertilizer at different times and to vary the distribution of the fertilizer. Further, when a fast-release fertilizer and a slow-release fertilizer are mixed at the time of spreading, the mixed fertilizer itself may be uneven, and the mixing ratio must be determined by an expert.

（問題点を解決するための手段）この発明はかかる従前における不都合に鑑みて案出され

is limestone powder, and (2) is carbonated limestone powder, and 2
It is a powder that passes through 60% of the 00 mesh, but the two lime powders (1) and (2) are mixed in equal amounts, the mixed lime powder is pressurized and formed into a plate shape, and then this is crushed and then passed through a sieve to obtain granular magnesium lime (3) with a size of 1 to 4 m/m.

（効果）以上に於ける構成よりして、この発明は以下の諸物件を
有する。(Effects) Based on the above configuration, this invention has the following properties.

即ち、（ａ）　　酸性土壌の矯正と植物に必要とされる苦土の
補給に際して、含有される苦土生石灰は速効性であり、
又炭酸苦土石灰は遅効性であるため、長期間に亘る一定
の肥効を約束し得る。That is, (a) the contained magnesium quicklime is fast-acting in correcting acidic soil and replenishing the magnesium soil required by plants;
Furthermore, since carbonate magnesium lime is slow-acting, it can promise a constant fertilizing effect over a long period of time.

（ｂ）　　混回苫土石灰肥料を顆粒体としたことにより
、従来の粉体石灰肥料に比して粉塵を発生することなく
、又それによる撒布のかたよりを有効に防止し得る。(b) By making the mixed tomato lime fertilizer into granules, it does not generate dust compared to conventional powdered lime fertilizers, and it is possible to effectively prevent uneven distribution due to the dust.

（ｃ）　　又、かかる石灰肥料を顆粒体としたことによ
り、雨風による流乏が減り肥料効果を増すと共に、単位
面積当りの撒布量が計画的に実施可能とされ作業能率の
向上とコストの低下を期し得る。(c) In addition, by making the lime fertilizer into granules, it is less likely to be washed away by rain and wind, increasing the fertilizer effect, and making it possible to spread the amount per unit area in a planned manner, improving work efficiency and reducing costs. We can expect that.

（ｄ）　　更にかかる石灰肥料を顆粒体としたことによ
りブロードキャスター等の農業機械での撒布が可能とな
り、単位時間当りの撒布量、撒布面積が増大し１作業を
容易性と。(d) Furthermore, by making the lime fertilizer into granules, it becomes possible to spread it using agricultural machinery such as a broadcaster, increasing the amount of spreading per unit time and the area covered, making one task easier.

肥料を効率的に利用することが可能となる。It becomes possible to use fertilizer efficiently.
