A recent study has shown that both organic farming and the use of wildflower strips can boost biodiversity on wheat farms. Researchers from the University of Göttingen and other institutions compared the ecological and economic impacts of these methods over two years in nine different landscapes. They studied three types of winter wheat fields: conventionally farmed with wildflower strips, organically farmed, and conventionally farmed with no additional environmental measures. The results showed that both organic farming and wildflower strips increased biodiversity by 20% to 30% compared to conventional farming without any interventions.
Organically farmed fields had the highest number of wild plant species, while wildflower strips supported a similar number of species. However, wildflower strips attracted three times as many bee species as organic fields. Both methods, however, supported significantly more bee populations than conventional fields. Ground beetles, spiders, and hoverflies also thrived under both organic and wildflower interventions, with 20% to 30% more species compared to conventional areas.
Economically, organic farming proved to be the most profitable option. Even though organic wheat yields were 50% lower than conventional yields, profits were more than 150% higher. This was due to better market opportunities and EU subsidies. In contrast, the profit from conventional fields with wildflower strips was only slightly lower than the control fields when subsidies for the strips were included.
The study also found that conventional fields with wildflower strips had 5% lower yields and 21% lower profits than conventional fields without strips. This suggests that farmers might have planted wildflower strips in less productive or more peripheral areas of their farms. The findings highlight that organic farming and wildflower strips each support different species, making them complementary in promoting biodiversity. Combining such measures could help create agricultural landscapes that serve both ecological and economic purposes. The results of the study were published in the Journal of Applied Ecology.
