| Abstract: | This rescarch was conducted to evaluate the methods of extracting soil K. Results indicated that electro-ultrafiltration (EUF) extractable K was more closely correlation to K uptake by ryegrass than chemically extractable K did. It was concluded that EUF was a more reasonable method in both thcory and practice than chemical one in the soil K status cvaluation. |
