している。The industrial waste generated during polishing of this whetstone is usually 44μ
The clay has the following average particle diameter, and the clay used is preferably one with a relatively high count and a fire resistance of about 5K28 to 34. Next, these industrial wastes and clay are kneaded in a weight ratio of, for example, 7:3, extruded through a nozzle provided with predetermined holes, and sequentially cut into predetermined lengths. This yields a granular material. The above-mentioned kneading and extrusion are performed, for example, by an extruder well known as a so-called clay kneader, and the extruded material is cut, for example, at a position adjacent to a mouthpiece defined at the tip of the extruder. This is done using a rotating or reciprocating wire. Next, after rolling the granular material into a spherical shape and drying it,
For example, I 150 °C in a rotary kiln or other firing furnace.
The granular soil conditioner of the present invention can be obtained by bisque firing at a temperature of . This granular soil conditioner has countless fine pores, for example, 40% porosity, 25%
It has a water absorption rate of , a true specific gravity of 2°9, and a bulk specific gravity of 1.9.

されることとなる。An example of the composition of the granular soil conditioner is shown in column 1 of the table in FIG. In addition, the unit of the numerical value shown in FIG. 2 is weight percent. The granular soil conditioner thus produced is passed through a predetermined mesh sieve, then packaged and shipped.
次に、以」二のようにして製造された粒状土壌改良剤を
用いて下記のような試験を実施し、タマネギ（ヘビーオ
ニオン）の成長に及ぼす影響を調べた。Next, the following tests were conducted using the granular soil conditioner produced as described above to examine the effect on the growth of onions (heavy onions).
まず、試験管を１１本用意し７てそれらに水道水をそれ

図の表の■欄に示す粒状土壌改良剤の組成は、ｈ記の試
験後に測定したものである。First, prepare 11 test tubes and fill them with tap water.The 6 test tubes numbered 1 to 016 are filled with water only, while the 2 test tubes numbered 7 and 8 are filled with 10 test tubes in water. gram of the above-mentioned granular soil conditioner was added, and for three testers No. 9 to No. 11, 20 grams of the granular soil conditioner was added into the water. Next, we placed 1 m long tama spears on the openings of 11 test tubes, left them for 3 weeks, and measured the state of rooting and germination. The results were obtained. In addition, the second
The composition of the granular soil conditioner shown in column (■) of the table in the figure was measured after the test described in h.

判る。As is clear from the test results shown in Figure 3 above, in the test examples No. 7 to No. 11 of Group B to which granular soil conditioner was added, No. 11 of Group A to which granular soil conditioner was not added. - Compared to Test Example No. 6, the number and length of roots and the length of shoots are relatively significantly increased. here,
Tap water contains the same ingredients as soil, and 1ro
Z.
Since rO2 is significantly higher than soil, ZrO
It is presumed that the presence of 7 promoted rooting and germination. In addition, the average weight of roots per Icm in group B, to which the granular soil conditioner was added, was overall lighter than in group A, which indicates that group B has thinner roots.
なお、上記の試験データはタマネギを水道水中で栽培し

あっても、上記の粒状土壌改良剤の効果を略同様に得る
ことができると考えられる。The above test data is for onions grown in tap water, but tap water containing the same components as soil is roughly equivalent to soil containing water from rain or sprinkling. Considering this, it is thought that substantially the same effects of the above-mentioned granular soil conditioner can be obtained even when cultivating in soil.
また、上記粒状土壌改良剤は、タマネギ以外の植物であ

壌改良剤を使用すれば、芝の成長か促進され、冬場にお
いてもグリーンを好適に維持することが可能となる。Further, the granular soil conditioner can promote the growth of plants other than onions even more favorably. For example, if the above-mentioned granular soil conditioner is used on the grass of a golf course green, the growth of the grass will be promoted, making it possible to maintain the green well even in winter.

るようにしてもよい。In addition, in the above-mentioned embodiment, the granular material is formed from clay and the industrial waste left during grinding of the whetstone, but this is not necessarily necessary, and for example, instead of industrial waste as mentioned above, Alternatively, organic matter such as bulb pieces, cellulose, or wood flour can be mixed with granular element + A, and the organic matter can be dispersed during firing to form a granular soil conditioner. Larger pores may also be formed.
また、前述の実施例では、粒状素材は１１５０°Ｃにて

としての機能を好適に確保するためには、１０００〜１
３００°Ｃの範囲内の温度で焼成する必要があるのであ
る。Further, in the above embodiment, the granular material is fired at 1150°C, but it may be fired at a temperature within the range of I 000 to +300°C. That is, ZrO□
Since it contains a lot of Al2O3, 100
If the firing temperature is lower than 0°C, sufficient strength will not be obtained and it will easily weather, while if the firing temperature is higher than 1300°C, it will turn into mullite and lose its pores, so it will suitably maintain its function as a soil conditioner. In order to do this, 1000 to 1
It is necessary to bake at a temperature within the range of 300°C.
また、前述の実施例では、押出材を逐次切断して得られ
た粒状素材を九粒化した後焼成するように構成されてい
るが、粒状素材を九粒化することなくそのままの形状で
焼成するようにしてもよい。In addition, in the above-mentioned embodiment, the granular material obtained by sequentially cutting the extruded material is configured to be made into nine particles and then fired, but the granular material is fired in its original shape without being made into nine particles. You may also do so.
また、前述の実施例では、篩を通された後の粒状土壌改

にしてもよい。In addition, in the above-mentioned example, it is explained that the granular soil conditioner after being passed through a sieve is packaged and shipped as is, but this is not necessarily necessary. Alternatively, by drying a granular soil conditioner that has absorbed water such as liquid fertilizer or pH adjuster, the fertilizer or pH adjuster can be turned into a solid form. It is also possible to include it in the granular soil conditioner in its state, or it is also possible to include fertilizers, pH adjusters, etc. that are not separated in the firing process in the granular material before firing.
