 E-Mail The impact of ozone on soybean production can be predicted more accurately thanks to improvements to a computer modelling system. Surface ozone is a pollutant that affects plant growth by entering leaves and reducing the rate of photosynthesis, and rising ozone levels could severely limit production of crops including soy. Being able to estimate this damage on soybean production using a climate-vegetation model is vital for predicting global and regional soy yields in the future. This study uses results from a field experiment in the USA, which found that a normal ozone level of 10ppm/h (AOT40) could reduce soybean yield by 10%.
