PURPOSE:To prevent the damage by agrochemical pollution and increase the yield of crops. CONSTITUTION:A powdery or granular extraction residue of a plant is mixed with soil for agriculture, the obtained mixed soil is packaged with a paper sheet or a synthetic resin to obtain a packaged soil and a metal complex is added to the mixed soil. As an alternative, a powdery or granular extraction residue of a plant or a porous powder or granule of the residue is magnetized by a magnetizing treatment or a magnetized water treatment and fresh soil is kneaded with the produced soil singly or as a mixture of treated soils. |
