N2 - Provision of an adequate mineral supply in the diets ofruminants fed mainly on grassland herbage can presenta challenge if mineral concentrations are suboptimal foranimal nutrition. Forage herbs may be included ingrassland seed mixtures to improve herbage mineralcontent, although there is limited information aboutmineral concentrations in forage herbs. To determinewhether herbs have greater macro- and micromineralconcentrations than forage legumes and grasses, weconducted a 2-year experiment on a loamy-sand site inDenmark sown with a multi-species mixture comprisedof three functional groups (grasses, legumes and herbs).Herb species included chicory (Cichorium intybus L.),plantain (Plantago lanceolata L.), caraway (Carum carviL.) and salad burnet (Sanguisorba minor L.). We alsoinvestigated the effect of slurry application on themacro- and micromineral concentration of grasses,legumes and herbs. In general, herbs had greaterconcentrations of the macrominerals P, Mg, K and Sand the microminerals Zn and B than grasses andlegumes. Slurry application indirectly decreased Ca, S,Cu and B concentrations of total herbage because of anincrease in the proportion of mineral-poor grasses. Ourstudy indicates that including herbs in forage mixturesis an effective way of increasing mineral concentrationsin herbage.
