Nowadays agricultural firms are more often than in the past decades forced to adapt operations, plans, strategies etc. to changes and uncertainties in their legal and business environment. The Balanced Scorecard (BSC) as an approach to strategic controlling in agriculture is discussed as an answer to the growing management demands in Danish farms. A brief description of the BSC-concept, its development process as well as principle potentials and limitations is given. In a case example on a dairy farm the current Danish strategic planning framework and the BSC are compared. The need for a stricter orientation of strategic planning to external demands (customers, stakeholders) is emphasised. Necessary prerequisites for the implementation of the BSC-concept into practical farming are discussed. Finally five critical success factors to the BSC adoption by Danish farmers are identified.
Abstract
We fogged trees in two pine dominated forests in Norway with a synthetic pyrethroid in order to compare the canopy-dwelling fauna of arthropods between costal (Kvam) and boreal (Sigdal) sites and between old (250-330 years) and mature (60-120 years) trees at Sigdal. Almost 30,000 specimens were assigned to 510 species; only 93 species were present at both sites. Species diversity, as established by rarefaction, was similar in old and mature trees. However, the number of species new to Norway (including nine species new to science) was significantly higher in the old trees. We suggest that the scarcity of old trees, habitat heterogeneity and structural differences between old and mature trees may explain these patterns. Productivity and topographic position at the site of growth explained the between-tree variation in species occurrence for the more abundant species, which were mainly Collembola and Oribatida. Species diversity was similar at the boreal and coastal sites, but there were clear differences in species composition

Artikkelen omhandler forsøksopplegg og reslultater av forsøk med 1) små feilfri prøver tørket ved temperaturer 30 - 60 - 90 - 120 grader og 2) prøver av varierende lengde/kvalitet av vanlig, industrielt fremstilt trelast av gran. For trelast tørket ved temperatur opp til 60-75 grader er det liten endring av likevektsfuktigheten (LVF) og i hysterese, med økende effekt for høyere tørketemperatur. LVF ble funnet å øke proporsjonalt med logaritmen av prøvens lengde, og slik at prøver med kvist mv. har 0.4 %-enh. lavere LVF enn feilfri prøver av samme lengde. Også hysteresis øket med økende lengde. Ettersom bare en begrenset del av området for faktorer som påvirker LVF og hysterese er undersøkt, bør undersøkelsene fortsette.
