Abstract

The present invention relates to environment protecting fertilizer. The utilization ratio of general inorganic phosphatic fertilizer is low, because when applied to soil or water, the inorganic phosphatic fertilizer is easy to fix by metal ions, such as calcium ions, magnesium ions, iron ions, aluminium ions, etc., and adsorb by clay mineral particles. As a result, the fertilizer efficiency is reduced, and environments are polluted. Phosphate fertilizer presently used for fertilizer water of aquaculture industry is mainly calcium superphosphate, and phosphorus needs to be complemented because of the lack of phosphorus nutrition. In addition, common phosphate fertilizer is phosphoric acid, and phosphate radicals are easy to fix by metal ions in waste water, so that the utilization ratio of phosphorus is lowered. Excess addition not only increases the medicine cost, but also makes phosphorus content in water easy to be above the standard. The present invention aims to develop high concentration composite organic phosphate fertilizer which has a high utilization ratio of phosphorus and can be used for fertilizer water of aquaculture industry and the biological treatment of organic waste water.
