  Based on the limited phosphate resources on the earth and phosphate resource situation in China,a series of processes in extending the longevity of the phosphate resources are developed and industrialized by "Yuntianhua-Zhengzhou University"(YTH-ZZU in brief)and their coalitions,which includes the following :(1)Phosphate ore containing 15%~25%P2O5 can be concentrated into commercial phosphate rock(containing 30%P2O5)through efficient beneficiation to produce ammonium phosphate and TSP.

Continuous inputs of nitrogen(N)through atmospheric deposition or N fertilizers,the important global change drivers,are likely to change soil phosphorus(P)availability,and thus affect long-term forest
There are some metal ions in the Low or middle-grade phosphate rock,especially when the Mg2+is excess,which is still exist in the phosphoric acid by wet process and that will bring a series of complex

Phosphorus is one of the essential elements for plant growth.Long-term overgrazing usually causes soil P deficiency in grassland.Stipa grandis and Leymus chinensis are dominate species of typical step
Natural resources represent global assets containing extraordinary economic value indispensable for societal and technological development.Early examples like stone,bronze and iron ages show the depen
