The present invention also relates to agricultural and horticultural soils made from lime sludge, Oya stone cuttings and red or black soil.

用いている。In the present invention, "lime sludge" means
After mining lime and dolomite, it refers to sludge generated when washed with water to obtain calcined raw materials and lime-based fertilizer. "Otani stone cutting waste" is the green tuff typified by Otani stone that is used for mining and processing. This is the cutting powder generated at that time. "Red soil" is generally the subsoil of volcanic ash soil, and is the lower soil of the Kanto loam layer in the Kanto region. "Black soil" means soil that is black and has a lot of humus. In the Kanto region, the topsoil of the multi-humic Kuroboku soil on the plateau is used.

This slurry is processed by a filter press and a large amount of sludge is generated as a cake, but most of the sludge has not been used because it has been landfilled or piled up. There are many proposals for using waste as agricultural material.
(For example, JP-A-5-339568, 10-8476
7, 11-335663), but no target for lime sludge. From the point of view of direct use in agriculture, limestone and dolomite fall under the Fertilizer Control Law as calcareous fertilizers, and since there are specifications for their components and particle size, they are ground after washing with water and have a specified particle size and component. It is used as a product or as a granulated product having a size of about 1 to 4 mm.

However, since green tuff contains natural zeolite and has a cation exchange ability, it is useful as a so-called "earth-growing material" for the purpose of improving soil fertilizing ability in agriculture. Especially, cation exchange capacity CE
Those with C of 50 meq or more are designated as soil improvement materials used in the soil strength enhancement method. As an example of the use of natural zeolite, it is proposed to use a high temperature fired product for preventing the outflow of agricultural chemicals from the golf course (Japanese Patent Laid-Open No. 5-8636).

It is made of granules. The significance of mixing cannot be obtained unless at least 10% of Otani stone cutting waste is added, but if the amount exceeds 70%, granulation of the mixture becomes difficult and the problem of waste treatment is related to lime sludge. Since it is more serious, there is a circumstance that it is desired to use a large amount of lime sludge, so the above-mentioned mixing ratio was set.

It is desirable to heat-sterilize this soil before use. The presence of Ca and Mg components may cause the soil to become alkaline, so the pH may be adjusted to 7.0 if necessary.
Or adjust to less. The pH can be adjusted by increasing the amount of red soil or black soil, but it is more effective to add an acidic fertilizer such as ammonium sulfate, lime superphosphate, or potassium sulfate. This soil is 1 Kg (having a particle size of 2-4 mm) when measured with a Kiya type hardness meter by firing.
Those having the above strength can be produced. The burned soil is a horticultural soil that has a good appearance and can be stored easily.
