This If the farmers were to rely on nature, it would probably take 10 to 20 years to rejuvenate the fertility of the soil. Then, they projected how current AECs would shift if they imposed future climate change projections (and associated changes in these bioclimatic variables) on top of todays technological, environmental, and cropping system situations. It can be used to reduce the weed seedbank by allowing weeds to germinate, then killing them before they set seed.
