It is important to recognize that the findings of the Which? Gardening study are based on organic gardening, which is not the same as certified organic farming. As the article itself notes, “Gardening organically and farming organically are very different. There are strict rules for farmers; they can, for example, only add fertilizers to their soil if tests prove that it is lacking in nutrients, and if they state that they farm organically they must have certification from an appropriate body to prove it. Gardeners, of course, face no such restrictions.” As such, the results of the study should not be construed to reflect the nutritional quality or the taste of products produced from certified organic farming. It is also worth noting that the differences between the organic and non-organic produce examined in the Which? study were small. For example, researchers "couldn’t distinguish any real difference in taste” between the organic and non-organic calabrese or the two types of potatoes being examined. At the same time, they found “there was no difference in quality” between the organic and non-organic tomatoes. The study also revealed that the produce raised organically exhibited several positive characteristics. The organic potatoes, for example, had slightly less scab and cracking than their non-organic counterparts. At the same time, the organic calabrese was more uniform in color than the calabrese raised using non-organic methods. Together, these findings illustrate that, at best, more research needs to be done before concluding which method of gardening, organic or non-organic, yields the most flavorful and nutritious produce.
