The study attempted to determine which plant characteristic was best correlated to acetylene reduction, and at what drought point it would stop. Four legumes were compared: vetch, red clover, -- clover, and black medic. All showed a drop in acetylene reduction around 8% water content on a clay soil. The correlation of various plant parameters with acetylene reduction was poor.
