The study, led by Georg Andersson of Lund University in Sweden, investigated the effect of organic farming compared to conventional. They found that the pollination success increased greatly with organic farming, and speculate that this effect may be due to an increase in insect pollinator abundance and/or diversity. They also determined that this effect was apparent within two to four years of the conversion, suggesting that there is not a significant lag time before pollination benefits are seen after adopting organic farming practices.
