According To Study, Which Are Better for Bees, Organic Farming or Flower Strips?

The effectiveness of agricultural environmental interventions for biodiversity and wild bee populations is determined by a variety of factors, including your point of view.

Agroecologists from the University of Göttingen in Germany and the Centre for Ecological Research in Vácrátót in Hungary demonstrate this.

The study team discovered that biodiversity benefits should be evaluated differently when measuring the success of different initiatives, whether in the field (organic farming) or adjacent to the field (flower strips in conventional farming).

According to the experts, like-for-like comparisons of environmental measurements can be deceptive.

The findings were reported in the journal Basic and Applied Ecology.

The researchers looked at ten agricultural landscapes near Göttingen, each with three winter wheat fields: one organic, one conventional with flower strips, and one conventional without flower strips.

The number of wild bees was monitored at the borders of each of these thirty fields for two years.

The findings revealed that a simple comparison of data collected in specific areas might lead to the idea that conventional fields with flower strips may attract many more bees than organic fields, but this is not the whole explanation, as per ScienceDaily.

When we examined more closely, we discovered that this did not provide a whole picture since it did not account for the fact that flower strips only cover around 5% of ordinary fields, which had far fewer flowers, Professor Teja Tscharntke of Göttingen University's Department of Agroecology explains.

In short, organic farming, which often contains more wild plants than traditional fields, is actually more successful than conventional fields with flower strips in fostering bees, according to Dr. Péter Batáry, group head at the Centre for Organic Research in Vácrátót, Hungary.

The missing piece of the puzzle is that organic grain fields generate just half the crop of conventional farming.

When wheat yield loss is considered, a ten-hectare organic agricultural area should be compared to five hectares of conventional farmland + five hectares of flower strips, which would result in 3.5 times more bees but the same yield.

Organic gardening would not be the greatest approach to assist wild bees in this case.

Organic farming

Organic farming is an agricultural technique that employs environmentally friendly pesticides and biological fertilizers produced mostly from animal and plant wastes, as well as nitrogen-fixing cover crops.

Modern organic farming was established in reaction to the environmental harm caused by conventional agriculture's use of chemical pesticides and synthetic fertilizers, and it offers significant ecological benefits, as per Britannica.

Sir Albert Howard, F.H. King, Rudolf Steiner, and others established the principles of organic agriculture in the early 1900s, believing that the use of animal manures (typically converted into compost), cover crops, crop rotation, and biologically based pest treatments resulted in a healthier agricultural system.

Howard, who worked as an agricultural researcher in India, was inspired by the traditional and sustainable farming techniques he saw there and campaigned for their adoption in the West.

Such approaches were supported further by numerous champions, including J.I. In the 1940s and 1950s, Rodale and his son Robert produced Organic Gardening and Farming magazine, as well as a variety of organic farming publications.

Flower strips

In a number of ways, in-field wildflower strips go beyond beetle banks, as per UK Center for Ecology and Hydrology.

The fact that they are focused on fostering different groups of predatory and parasitic insects that eliminate pests is maybe the most crucial.

According to research, complex communities of predators and parasitoids are the most successful in pest management.

The in-field flower strips are also intended to provide pollen and nectar supplies for early-season agricultural pollinators including bumblebees and solitary bees.

In this regard, they should bring two advantages: improved natural pest management and crop pollination.
