Urban Farm DB summary
A 5-year experiment (2015-2019) in China compared weed occurrence in a corn–earthworm coculture (CE) system and a corn monoculture (CM). The CE system significantly decreased weed diversity, dominance index, total weed density, and biomass, while increasing the weed evenness index. The 5-year mean number of weed species per plot was 8.4 in CE versus 10.7 in CM, and total weed density and biomass in CE decreased by 59.2% and 66.6% respectively compared to CM.
