| Research Abstract |
In the current studies, plant performances just occurring in soil as a heterogeneous system were investigated and considered their applications to alleviate soil stress. Localized supply rather than uniformly supply of phosphate, which is immobile in soil, was shown to be effective for plant growth. When a root system encounters spatially heterogeneous soil moisture, water efflux can occur from the root into dry soil. By using the process, some root system had a potential to reduce salinity level of saline water. It was found that Al toxicity, which is a major factor of acid soil stress, could be alleviated by soil compaction.
