Problems solved by technology
[0003] Especially recently, as the frequency of acid rainfall has increased, soil acidification has further accelerated, resulting in a significant reduction in agricultural productivity and tree growth in forests.
[0004] To neutralize the acidic soil, calcium carbonate (CaCO 3 ) or quicklime (CaO), etc., but if too much lime is used, it is easy to reduce the ratio of magnesium (Mg) to calcium (Ca) in the soil, resulting in magnesium (Mg) deficiency
[0005] Although this chemical treatment can neutralize the acidic soil, on the other hand, there is the following problem: when in contact with water, heat is generated, thereby significantly reducing the presence of beneficial microorganisms with natural purification capabilities in the soil, thereby reducing the soil's natural Purification ability, and destroy the physical and chemical balance of the soil, thereby reducing the regeneration ability of the soil, thereby harming crops

[0080] Examples 1-7 and Comparative Examples 1-6: Manufacture of soil conditioner
[0081] First, the bauxite residue (the particulate insoluble residue (SiO 2 25.8% by weight, Al 2 o 3 20.8% by weight, Fe 2 o 3 23.8% by weight, CaO 2.68% by weight, K 2 O 0.09% by weight, Na 2 O 10.5% by weight, TiO 2 5.39% by weight, MnO 0.06% by weight, P 2 o 5 0.03% by weight)), curing agent (molasses) and thickener (bentonite) are mixed into the granulation system and stirred for one minute. As a result a solid mixture was obtained.
[0082] The pan was then tilted by 50° and the pan shaper was rotated at a rotational speed of 40 rpm so that the solid mixture slowly fell into the pan. At the same time water is added to the disc former through nozzles.
[0083] The rotation speed of the disk was then adjusted to 60 rpm for 20 minutes. The result is a granulated soil conditioner.
[0084] Table 1 below shows the ratios of bauxite residue, molasses, bentonite and water for...

A composition for preparing a soil conditioner, the soil conditioner and a method of conditioning soil are disclosed. The disclosed soil conditioner comprises 100 parts by weight of bauxite residues,5 to 15 parts by weight of a solidifying agent, 5 to 25 parts by weight of a thickener, and 7.5 to 10 parts by weight of water.
Description
technical field [0001] The invention discloses a composition for making a soil conditioner, a soil conditioner and a soil conditioner method. Specifically, a composition for producing a soil conditioner capable of improving acidic soil to a soil within a pH range of 6.0 to 8.0, a soil conditioner, and a soil conditioner method are disclosed. Background technique [0002] Usually more than 50% of Korean soil is composed of granite and granitic gneiss. Due to the concentrated rainfall in summer, soil loss and calcium (Ca) leaching, as well as excessive use of chemical fertilizers, etc., gradually acidify the soil. [0003] Especially recently, as the frequency of acid rains has increased, soil acidification has further accelerated, resulting in a significant reduction in agricultural productivity and tree growth in forests. [0004] To neutralize the acidic soil, calcium carbonate (CaCO 3 ) or quicklime (CaO), etc., but if too much lime is used, it is easy to reduce the rati...
