Aims of this study were to measure the effects of fodder crop species with contrasting root traits and duration of cropping on BP density (BPD), and also to address the consistency of these effects over different years focusing on the effects of root decay. Methods: Soil BPD was quantified after growing three perennial fodder crop species with contrasting root systems, namely, lucerne (Medicago sativa L.), chicory (Cichorium intybus L.) and tall fescue (Festuca arundinacea Schreb.) for 1, 2, and 3years with 2years fallow in two repeated field trials from 2007 to 2014. Results: Total BPD after taprooted fodder crops (421 ± 14m−1) was significantly higher compared with fibrous-rooted crops (337 ± 12m−1). Cropping duration did not affect soil BPD. On average, density of medium-sized BP (BPmed; 2-5mm) increased 14% after 2years of fallow, whereas BPD decreased by 5% for coarse-sized BP (BPcor; >5mm) after the fallow. Conclusions: Taprooted fodder crops enhanced BP formation into subsoil. Accurate assessment of biopores (BPs) and their persistence must take account of the temporal dynamics, including effects of root decay.
