Rebaling of silage and haylage and its effects on forage microbial and chemical composition—A pilot study
(Peer reviewed; Journal article, 2020-04-22)Use of big bale silage and haylage can be difficult on farms where daily forage consumption is comparatively low as speed of deterioration of forage after bale opening may be faster than feed‐out rate. Production of smaller ... -
Recent strengthening of snow and ice albedo feedback driven by Antarctic sea-ice loss
(Peer reviewed; Journal article, 2021-10-28)The decline of the Arctic cryosphere during recent decades has lowered the region’s surface albedo, reducing its ability to reflect solar radiation back to space. It is not clear what role the Antarctic cryosphere plays ... -
Recent warming across the North Atlantic region may be contributing to an expansion in barley cultivation
(Journal article; Peer reviewed, 2017-12)Although grass dominates most agricultural systems in the North Atlantic region (NAR), spring barley is the most important cereal and is used for animal feed and food and drink products. Recent changes in climate have ... -
