Weed seedbanks are a key driver of long-term weed pressure and are strongly shaped by farming systems, crop rotation, and intercropping. This study evaluated the influence of organic (ORG) and conventional (CONV) farming systems, each managed under high (113–145 kg N·ha−1, 60–83 kg P·ha−1) and low (31–45 kg N·ha−1 and 13–27 kg P·ha−1) fertilization levels, on weed seedbank density, composition, dominance, and diversity in two long-term trials (established in 2007) at Chuka and Thika in the Central Highlands of Kenya. From 2017 to 2019, across six cropping seasons under a three-year rotation, soil …
