From Mark De Young
The vision of turning “barren, salt-laden soils” into “lush farmland” by
growing genetically modified plants whose leaves accumulate sodium has one flaw
(4 August, p 13). What happens to the sodium as the leaves decompose back into
the soil? To regenerate saline soils, surely these leaves would need to be
removed to enable a net removal of salt.
