摘要：
The efficiency of recovery of P by iron oxide-impregnated filter paper, as used in the new P(i) test for soil phosphorus, was found to depend on the method used for impregnating the paper with iron oxide and could range from as little as 28% to more than 98%. The greatest efficiency of recovery was obtained with filter papers which had been washed with deionised water following iron oxide-impregnation. These filter papers were also found to give the most reproducible results.
