摘要

PROBLEM TO BE SOLVED: To provide a crop growth promoting material suppressing absorption of heavy metal by crops to promote crop growth and enabling producing crops using as a farm land soil polluted with heavy metal as it is, to provide a crop growth promoting method using the material and to provide the crops. SOLUTION: This crop growth promoting material comprises a vaterite-containing substance. The BET specific surface area value of the vaterite-containing substance is≥5 m2/g, and the vaterite-containing substance comprises calcium silicate and/or a carbonated product of calcium silicate hydrates. The crop growth promoting method comprises mixing the crop growth promoting material with soil. The crops raised by the crop growth promoting method are also provided. COPYRIGHT: (C)2006,JPO&NCIPI
