Agroforestry can be defined as sustainable and multifunctional land-use systems where trees are managed together with agricultural crops or livestock on the same piece of land. This definition fits with how the outfield has been managed in generations in Norway. The Norwegian outfields are a multifunctional land-use system. In the northern periphery area, agroforestry has a long history with woodland grazing, reindeer husbandry and gathering of different non-wood forest resources as herbs, mushrooms, and berries. Traditional agroforestry has gradually disappeared during the 20th century with the intensification of agriculture and forestry. Currently agroforestry systems are gaining new interest, not only from farmers but also from politicians, as this practice can possibly contribute to a more sustainable way of agricultural production. In the northern periphery area, the benefits of agroforestry practices can be manifold not only promoting traditional practices, but also novel systems with the use of new technology. In addition, agroforestry has environmental benefits as a method for conservation and enhancement of biodiversity, improved nutrient cycling, and water quality. Soil humus layer will also increase with several agroforestry systems leading to carbon sequestration. The Norwegian population of 5.3 mill populate an area of 323805 km2. The mainland of Norway is 323805 km2 while Svalbard and Jan Mayen represent 61022 and 377 km2, respectively. Number of persons per km2 are 14, however, as much as 82% of the Norwegian population inhabits cities/densely populated areas. These figures tell us that Norway have a large outfield with forests and mountains. The biggest owner of Norwegian outfield1 is the Norwegian state by the Ministry of Agriculture and Food. The state-owned enterprise Statskog SF is set to administer the property, that alone consist of about 23% of the total outfield-area of Norway. Almost 80% of the state-owned property is above the treeline and covers mountains and alpine grassland who are valuable grazing resources for reindeer herders and local farmers. Most of the forests are also used as grazing areas for local farmers and reindeer herders. The state-owned property in the southern Norway are managed as commons, where locals have rights in commons, typically this is right to graze, hunt and fish on the state ground. In the northern part of Norway, the grazing-rights are defined as user-rights and technically not rights in commons while the right to hunt, fish and gathering of berries and herbs etc. is an “all-mans-right”.

This research aimed to determine if creeping bentgrass (Agrostis stolonifera L.) can be used as an alternative to colonial bentgrass (Agrostis capillaris L.) in a mixture with red fescue [equal rates of Chewings fescue (Festuca rubra ssp. commutata Gaud.) and slender creeping red fescue (Festuca rubra ssp. littoralis [G. Mey.] Auquier)] on Nordic golf greens managed without pesticides. The two mixtures were compared in two experiments: Experiment 1 under the creeping bentgrass management regime (mowing height, 3 mm; fertilization, 15 g N m−2 yr−1) and Experiment 2 under the red fescue management regime (5 mm and 10 g N m−2 yr−1) at three sites during 2015–2018. A seed mixture of red fescue and velvet bentgrass (Agrostis canina L.) was included in Experiment 2 only. The results showed that red fescue plus creeping bentgrass produced greens of equal turfgrass quality and with less Microdochium patch than red fescue plus colonial bentgrass under both regimes. In Experiment 2, red fescue plus velvet bentgrass resulted in higher turfgrass quality than the other mixtures but was more susceptible to Microdochium patch than red fescue plus creeping bentgrass. Tiller counts in the mixed plots at Landvik showed that red fescue was not outcompeted by bentgrass in any of the mixtures and that it was easier to manipulate the balance between red fescue and bentgrass in the mixture with creeping bentgrass than that with colonial bentgrass. More research should be put into optimal management, especially irrigation and thatch control, of mixed red fescue–bentgrass greens.
