The long term and overdose usage of chemical fertilizers in Taiwan have lead to the accumulation of unavailable phosphate (organic phosphate or mineral phosphate) in the soil. These forms of phosphates can not be utilized by crops. We have screened, isolated and characterized bacteria, actinomycetes and fungi with multi-functional phosphate solubilizing activities. However, the application of these phosphate solubilizing microorganisms on different crops will be important and needed. In the past, researches focused only on sole function of bacteria such as tricalcium phosphate or ferric phosphate solubilization. In order to efficiently develop superior phosphate solubilizing microorganisms which are useful on various crops, a team includes Professors C.C.Young, C.C. Tang, H.J. Chen and C.T. Lo in National Chung Hsing University and National Formosa University was established. Microbial consortiums include phosphate solubilizing bacteria, phosphate solubilizing actinomycetes, phosphate solubilizing yeast, and phosphate solubilizing fungi will be designed in the present study and their capabilities to promote crop growth will be demonstrated. The suitable phosphate solubilizing bacterial formula will also be designed. Consideration for the specificity and adaptation of phosphate solubilizing microorganisms to their host crops, the designed biofertilizers will be used as inoculants to increase the yields of various crops meanwhile reduce the overdose usage of chemical fertilizers.Collection of solubilizing-phosphate (PSM) microorganism from different properties of soils and otherstudy. Researching solubilizing ability of PSM in different available concentrations and kinds of fixed of phosphate, then screening appropriate PSM.
