| Abstract: | The effects of phosphate activator on phosphorus efficiency using 32 P trace technique were studied in the article. The results showed that applying phosphate activator can raise the supplying ability of soil and fertilizer phosphate improve improve the soybean sbsorbing phosphate from soil and fertilizer and also apparently increase the phosphate utilization efficiency. |
