Material for cultivation soils and method of manufacturing thereof

摘要

A material for cultivation soils having a continuous porous structure comprising combustion ash and carbon powder in which electrostatic charges are desorbed and neutralized and ettringite crystals for coagulating to connect the particles of the combustion ash and the carbon powder to each other, and the continuous porous structure comprising relatively large holes and smaller pores for connecting the holes to each other. The material for cultivation soils is produced by mixing the combustion ash and the carbon powder in which electrostatic charges are desorbed and neutralized, with either one of cement or calcium hydroxide, potassium chloride, magnesium chloride, sodium chloride, calcium chloride, sodium nitrate, ferric chloride, citric acid, cobalt chloride and water and then drying them.
