The findings seem unlikely to sway many fans of organic food. Advocates for organic farming said the Stanford researchers failed to appreciate the differences they did find between the two types of food#differences that validated the reasons people usually cite for buying organic.
Organic produce, as expected, was much less likely to retain traces of pesticides. Organic chicken and pork were less likely to be contaminated by antibiotic-resistant bacteria.

#Organic farming Benefits Go Beyond the Food, Into the Field (Op-Ed) This article was published originally at The Conversation.
Organic farming is a trade off: it prohibits the use of certain chemicals and inorganic fertilisers which usually results in lower yields and hence higher prices.
One reason may be in organic farming s effects not on us but on the environment. In our study published in the Journal of Applied Ecology we re-analysed data collected on biodiversity one potential environmental benefit of organic farming.
We looked at data from 94 previous studies dating back to 1989 covering 184 farms with different crops in
which biodiversity on conventional and organic farms was compared. This was measured in terms of species richness (the number of different species in a particular area or time rather than the number of individuals.
Incidental plants those not being grown as crops seem to benefit the most from organic farming while the largest differences in diversity between conventional and organic is seen in areas of intensive cultivation of cereal crops such as wheat maize and barley.
So consumers who choose to buy organic food can be sure they are paying towards a method that generates an environmental benefit.
One of the criticisms often levelled at organic farming is that while there are benefits to biodiversity lower yields mean more land is required to grow the same amount of food.
So is organic farming a zero-sum game? This is a much harder problem to address and there probably isn t a simple Answer for example in Europe arable farming has a very long history
Organic farming has been shown to maintain species diversity on farmland so it probably does provide one solution to these declines in Europe at least.
Although such estimates can only ever be crude our study revealed that organic farming had greater benefits in areas with high land-use intensity.
In which case perhaps we should deliberately encourage the scattering of organic farms around the landscape to maximise their impact.
Compared to the effects of organic farming the evidence that greening measures which encourage strips of wild habitat fallow land forests

Our study does not tell farmers they should shift to organic agriculture. What our study suggests is that organic agriculture is promoting these more balanced natural enemy communities

their study found that the increased evenness of organic farms compared with that of conventional farms led to 18%lower pest densities and 35%larger plants.
At least as important as what the research says about organic farming is what it says about species evenness.

#Organic agriculture boosts biodiversity on farmlandsdoes organic farming foster biodiversity? The answer is yes however the number of habitats on the land plays an important role alongside the type and intensity of farming practices.
The study shows that even organic farms have to actively support biodiversity by for example conserving different habitats on their holdings.
An international team including scientists from Technische Universitã¤t Mà nchen (TUM) investigated the contribution of organic farming to supporting farmland biodiversity between 2010 and 2013.
whether organic farms are home to more species than their conventional neighbors. The team used uniform methods across Europe to capture data
Organic farming is beneficial to the richness of plant and bee species. However observed benefits concentrate on arable fields says TUM's Prof.
His Chair for Organic agriculture and Agronomy analyzed 16 Bavarian dairy farms. The study investigated farms in twelve regions with different production systems.
Organic farming benefited the four taxonomic groups of plants earthworms spiders and bees --which were sampled as surrogates for the multitude of creatures living on farmland--in different ways.
Obviously most species found in fields on organic farms tend to be concentrated in boundary areas on non-organic farms.
The occurrence of rare or threatened species did not increase on organic farms according to Kainz. Even organic farms need to increase habitatsto sustain farmland biodiversity
which is currently under grave threat researchers have identified complement organic farming methods with dedicated efforts to conserve habitats.
To increase the number of habitats the authors of the study recommend adding structural elements such as woods grass verges
Surprisingly viewed across all regions we did not find a higher number of natural habitats on organic farms than nonorganic farms reports Kainz.

#Organic farms support more species, researchers findon average organic farms support 34%more plant insect and animal species than conventional farms say Oxford university scientists.
'Our study has shown that organic farming as an alternative to conventional farming can yield significant long-term benefits for biodiversity'said Sean Tuck of Oxford university's Department of Plant sciences lead author of the study.'
'For pollinators such as bees the number of different species was 50%higher on organic farms although it is important to note that the study only looked at'species richness'.'
Organic farms had a bigger impact on species richness when the land around them was farmed more intensively particularly
'We found that the impacts of organic farms on species richness were pronounced more when they were located in intensively farmed regions'said Dr Lindsay Turnbull of Oxford university's Department of Plant sciences senior author of the study.'
because the biodiversity benefits of each organic farm will be diluted in clusters of organic farms compared to an organic island providing rich habitats in a sea of pesticide-covered conventional fields.
'The impact of organic farming on total species richness varied significantly across the data with the average gain in species richness varying between 26%and 43%.
In such cases the benefits of organic farming are less clear as this may require more land to achieve the same yield as conventional farming.'
