Future drought will offset benefits of higher CO2 on soybean yields

Plant biology professor Andrew Leakey and colleagues report that soybeans will suffer yield losses sooner than previously predicted under future conditions that combine elevated atmospheric carbon dioxide levels with drought.

An eight-year study of soybeans grown outdoors in a carbon dioxide-rich atmosphere like that expected by 2050 has yielded a new and worrisome finding: Higher atmospheric CO2 concentrations will boost plant growth under ideal growing conditions, but drought – expected to worsen as the climate warms and rainfall patterns change – will outweigh those benefits and cause yield losses much sooner than anticipated.
