摘要： The present invention relates to fertiliser composition comprising from 95% to 1% by weight, based on the total weight of the fertiliser composition, of a phosphate fertiliser and from 5% to 99% by weight, based on the total weight of the fertiliser composition, of a phosphate binding substance selected from the group consisting of red mud that has been at least partially reacted with a material comprising at least one of calcium ions and magnesium ions, red mud that has been at least partially neutralised by addition of acid, red mud that has been at least partially neutralised by treatment with carbon dioxide, and red mud that has been at least partially neutralised by addition of at least one mineral containing at least one of calcium ions and magnesium ions, the phosphate binding substance having a reaction pH, when mixed with 5 times its weight of water, of less than 10.5. There are further provided methods for preparing the fertiliser and methods for fertilising soils.
