Résumé : | Potential damage to wetlands by land-use practices has prompted a need for relatively inexpensive, reliable indicators in monitoring ecological conditions. In this study, soil classification and the following soil tests, sodium bicarbonate-extractable P, nitrate (NO3-) organic matter (OM), pH, electrical conductivity (EC), and 137 Cs distribution, were used to compare four wetlands surrounded by cultivated land or grassland. |
