The soil conditioner of this invention is basically composed of 4 to 4.75 parts by weight of coal ash, 4 to 4.75 parts by weight of slag, and 0.5 to 2 parts by weight of zeolite, and is useful for the overall improvement of soil including not only chemical and physical conditioning of the soil but a

The soil conditioner of this invention is basically composed of 4 to 4.75 parts by weight of coal ash, 4 to 4.75 parts by weight of slag, and 0.5 to 2 parts by weight of zeolite, and is useful for the overall improvement of soil including not only chemical and physical conditioning of the soil but also improvement of its ecological system. In addition to the aforesaid ingredients, this soil conditioner may contain a microorganism having the function of competing with the harmful microorganisms present in the soil or utilizing them as nutrient sources to eliminate the detrimental effects thereof, thereby inducing the propagation of useful microorganisms in the rhizosphere of the desired crop and promoting the growth of the crop, as well as 0.2 to 2% by weight of molasses based on the total weight of the coal ash, slag and zeolite.
