A meta-analysis of 226 studies, led by Wageningen University & Research in the Netherlands, showed that intercropping can significantly increase yields while reducing fertilizer inputs. The study concluded that intercropping appears to give a 16-29% larger yield per unit area than monocultures in intensive agriculture under the same circumstances, while using 19-36% less fertilizer per unit product. The study results were published in Nature Plants, and researchers noted that these results applied to intensive agriculture as well as low-input agriculture.
