PROBLEM TO BE SOLVED: To artificially reproduce a mechanism that a plant release the electric charge by the adsorbed and adherent water for a short time. SOLUTION: The soil texture and soil conditioner includes at inorganic metal salts, for example, sodium chloride, potassium chloride, magnesium chloride and calcium chloride in addition to citric acid and manifests the function to weaken the electric charge of the adsorbed and adherent water on the soil particles, the function to convert the adsorbed and adherent water having weakened electric charge to free water and the function to form and develop needle crystals. The soil modified with the soil conditioner according to this invention solidifies as the soil particles construct the card-house structure. In the resultant solid soil, the space in the card-house structure forms ultramicroporus pores of the angstrom level having spaces communicating to each other thereby giving continuously porous bodies of markedly increased water permeability and air permeability. |
