The research showed that SP11 improved nitrogen, phosphate and potassium contents of the pea plant significantly in phosphate-lack soil. Especially SP11enhanced 32.6% nitrogen content, 22.5% potassium content of the pea plant in rock-phosphate fertilizer treated soil compared to soil without phosphate fertilizer. SP11 and T50 also improved soil microbial biomass. T50 has back effects on growing of the pea plant in this experiment although it can improve nitrogen content of the pea plant in available phosphate treated soil. SP11 is the better microbial fertilizer.
