用いられる酸性土壌用地力涵養剤に関するものである。Detailed Description of the Invention (Field of Industrial Application) The present invention addresses the effects of acid rain on topsoil, including changes in underground hydrogen ion concentration, imbalance of plant-useful elements, and destruction of microbial cycles. This invention relates to a soil recharge agent for acidic soils that is used to reduce the effects of acid rain and restore soil fertility to the resulting decline in surface soil strength.

っている。Acid rain penetrates into the soil and leaches calcium, magnesium, etc., which are important nutrients for plants, making the soil malnutritive.
As acidification progresses, harmful metal ions in the soil are eluted, fatally destroying plant root threads. This also destroys the microbial cycle in the soil, which has a closer symbiotic relationship, and renders the topsoil incapable of supporting plants. This kind of destruction of topsoil can be dealt with locally using conventional soil conditioners, seedling raising soil, culture soil, etc., but in forests, fields,
It cannot be an effective means for destroying topsoil in large areas such as mountains, and countermeasures are currently an urgent issue in terms of national land conservation.

素イオン濃度においてもｐＨ１０，２〜８．０と酸性雨
対策用資材として好適であり、加えてスラッジ焼却灰は
濾水性に優れている。Since the pulp sludge incineration ash is a plant combustion residue, its composition is composed of essential plant components, and the hydrogen ion concentration has a pH of 10.2 to 8.0, making it suitable as a material for countermeasures against acid rain. In addition, sludge incineration ash has excellent drainage properties.
一方、石炭灰は、置換酸度を低下させる効果において良
好であると共に、保水性に優れている。On the other hand, coal ash has a good effect of reducing substitutional acidity and also has excellent water retention.
従って、パルプスラッジ焼却灰と石炭灰とは、各々単独

割合とすることで最も好ましい状態となる。Therefore, pulp sludge incineration ash and coal ash can not only be used alone, but also pulp sludge incineration ash, which has freeness, and coal ash, which has water retention, can be used as appropriate depending on the condition of the acidic topsoil. By mixing in proportions, it is possible to prepare materials that are most advantageous for topsoil restoration. In particular, the balance between water retention and freeness is most preferably achieved by setting the ratio of 10 to 70 parts by weight of coal ash to 1 part by weight of pulp sludge incineration ash (1 part by weight of lf).

55% (Effect of the invention) As mentioned above, the present invention uses mainly pulp sludge incineration ash discharged from paper mills, but also coal ash discharged in large quantities from thermal power plants in various places, either alone or in combination. By doing so, it neutralizes acidic soil, protects or restores the underground microbial cycle, and thereby contributes to the enrichment of surface soil, which is significantly related to the national land environment.The main raw material is available at an extremely low cost. Coupled with this great advantage, it also has great environmental conservation value from an industrial standpoint.
