| Recent research indicates autotoxic compounds leach faster through sandy soils than heavy-textured soils. |
| Some scientists are researching ways to genetically modify alfalfa to decrease the autotoxic effects. |
| A faulty null hypothesis may be accepted if the autotoxic potential of a test species is overlooked in density-response experiments. |
| New seedlings emerging within the autotoxic zone of the old plant still would not likely contribute to yield. |
| The chemical responsible for the autotoxic effects in alfalfa fields has not been conclusively identified. |
