Determination of soil available P by a technique of boried anion exchange resin membrane of domestic and exported |
| |
Abstract: | Soil available P in 20 soil samples all over the country was analyzed by different methods. The results showed that the available P values obtained from the resin technique were correlated significantly to those from Olsen method and evaluated by plant uptake. In addition, domestic resin is as good as imported for the determination available P in situ. |
