Grazed pastures are susceptible to N loss from urine/manure additions, which increases eutrophication, affecting the global N cycle. Plant secondary metabolites (PSM), such as condensed tannins (CT) and terpenes, influence silviculture soil dynamics by generally decreasing N mineralization. We investigated whether cattle‐grazed pastures of non‐traditional grass and legume forage monoculture strips including CT‐containing sainfoin (Onobrychis viciifolia Scop.) and tall fescue (TF) [Schedonorus arundinaceus (Schreb.) Dumort.] influenced soil dynamics compared with traditional grass and legume forage monoculture strips of alfalfa (Medicago sativa L.), without tannins, and TF. Throughout the study, CT in sainfoin averaged 58.9 g kg−1 …
