PURPOSE:To provide a soil conditioner having no foreign odor and being almost freed from fat and salt and relatively small in the content of nitrogenous, phosphatic and potash components. CONSTITUTION:A finely divided vegetable product such as a press residue of apples is used, and water is added to this residue. Calcium oxide is added to the obtained mixture and reacted, and the calcium compounds resulting from the reaction are mixed with and dispersed in fibers of the residue. In this, way, calcium hydroxide, calcium carbonate and an organocalcium compound such as a calcium salt of an organic acid are homogeneously mixed with the vegetable fibers to form a soil conditioner being relatively small in the content of nitrogenous, phosphatic and potash components and assuming alkalinity. When this conditioner is applied to soil, its calcium compounds can be satisfactorily dispersed in the soil and exhibits its alkalinity to neutralize and alkalify the soil without fail and to suppress the growth of bacteria adversely affecting plants through its disinfective effect. Because it is a mixture of vegetable fibers, it can absorb air among the fibers to improve the soil when mixed with soil. |
