Solid beef cattle manure is a good anaerobic digestion feedstock for methane production, but more research is needed to determine how co-products of the anaerobically digested manure may be used in crop production, while limiting the risk of nutrient loss to the environment. Over four growing seasons, we measured the N and P supplied to barley (Hordeum vulgare L.) forage test crops from (i) anaerobically digested solid beef cattle manure (digestate), (ii) separated solids from the digestate (separated solids), (iii) pelletized separated solids (pellets), and (iv) undigested solid beef cattle manure (manure) that were applied to target 1× (260 kg N ha -1 ) and 2× (520 kg N ha -1 ) the recommended N rates. Non-amended soil was the control. Digestate led to 31 to 50% greater barley forage yield than the other amendments. Th e apparent N recovery from digestate (19%) was much greater than pellets (2%) and about double that of the separated solids (9%) and cattle manure (10%). Th e barley N uptake derived from digestate was 41%, which was signifi cantly greater than manure (22%), separated solids (17%), and pellets (2%). Digestate increased P uptake, while signifi cantly reducing soil-test P accumulation compared with the other coproducts and cattle manure when applied at N-based rates. Our results confi rmed that management practices for solid beef cattle feedlot manure may be used for separated solids, but not digestate. Pelletized separated solids may be an eff ective slow release fertilizer, while also supplying C, but determination of its nutrient release patterns is required.
